    Onofreo saved Christmas!Woke up to a very cold house the weekend before Christmas. Talk about panic! No heat, temps are plummeting toward single digits, and we’re hosting Christmas in a couple days. First call was to Onofreo! They arrived within a few hours and quickly diagnosed the issue. Unfortunately it was not a quick fix but one that required a plan and strategy. They came up with several different approaches, looking at it from all angles (short term, long term, cost, etc). They thoughtfully walked me through the pros and cons of each scenario. My wife and I selected the option we felt most comfortable with, and the crew was here Monday morning to execute. The team was friendly and professional and got it done as planned. Would highly recommend Mark and his crew.Merry Christmas!!!

    We had our 2 air conditioning units replaced with 2 heat pumps in the Spring of this year, 2024. Everyone involved did a terrific job. All knowledgeable and extremely helpful. Good folks. Honestly wouldnt hesitate to use them again.

    Replaced old oil furnace with new high efficiency gas furnace 2 years ago. (no problems) Excellent removal including in basement oil storage tank. Very nicely done installation of furnace and additional gas line to new gas range. Quite a savings from oil furnace. Additionally, this year they needed to look at my AC (16 yrs. old) expected new installation but instead a fairly minor repair. Honesty is very welcome! Thank You Onofreo! Of course, AC is on borrowed time.

    Onofreo exceeded all our expectations when they installed our new air conditioning unit two years ago. On a sweltering summer day, after we had endured days without AC, their team arrived ready to tackle the challenge. The installation proved more difficult than anticipated, with stubborn, cemented bolts in hard-to-reach places in our attic. Despite the grueling heat and unexpected complications, the technicians worked tirelessly without a single complaint, demonstrating true professionalism and dedication.What impressed us most was their integrity in recommending an AC unit that perfectly suited our homes needs, rather than pushing the most expensive option. This thoughtful approach has paid off – our house has been wonderfully comfortable ever since the installation. Their commitment to customer satisfaction didnt end there. In the two years since, Onofreo has provided exceptional maintenance service. Even during their busiest summer periods, theyve managed to squeeze us in for urgent repairs, showcasing their reliability and genuine care for their customers. From installation to ongoing support, Onofreo has consistently delivered top-notch service.

    Had a furnace installed by these guys they did an amazing job had a small issue almost a year later. They took care of me,no questions. Im also out of town and not able to be there communication was great very trust worthy. Ill use them again for sure and reccomend them 1000%.

  • Review 6 (2024-08-15 - Rating: 5)

    Onofreo came through with flying colors for us twice - in the winter and the summer! Our aging furnace decided to conk out during one of the coldest weeks of the year, right around Christmas. Within two days (during which they lent us space heaters), they were able to install a brand new furnace and fancy new thermostat. Come summer during one of the hottest days of the year, our central a/c died. They came out the next day, diagnosed, and replaced the almost 20 year old a/c motor. During the whole process, their team was polite, efficient, responsive, and all the work was reasonably priced. Do not hesitate to call. Highly recommend!

    The office staff is friendly and helpful. The work crew was punctual and polite. All work was done to my satisfaction. Price was fair. Over all I was very happy with the whole job.

    Very professional and very knowledgeable in the work they did in the upgrade conversion of our home heating and air conditioning system in our new home. I would not hesitate in asking for their services.

    Working with Onofreo has been a really good experience for me. They are fairly prompt. Shayna is very prompt with communication to set everything up. I will work with them again.

    Extremely responsive whenever called. Very reassuring to know they will get back to you, even on a weekend. Installed a new heating and air conditioning unit for me and is working great. Will set up a contract with them in the fall . Pleasure doing business with Onofreo Systems.

    Amazing company. I’ve used them on multiple homes for different large projects and they are right on target with the process each time . No guess work, and follow through to completion and beyond without a hitch. They go above and beyond and are reasonable with costs. No gouging.! Highly recommend.

    Onofreo installed my new air conditioner and gas furnace in May, 2020, and has continued to service them ever since. I have nothing but praise for this company. They are responsive, honest, reliable and customer-centered. I highly recommend them for your home comfort needs!

    Very professional company Replaced an ancient central a/c system for me last yearThey came when promised, finished on schedule, were neat and pleasant to work with. Lastly, their price was competitiveJust a solid company with old fashioned service, rare to find these days.

  • Review 17 (2024-07-12 - Rating: 5)

    We couldnt be more satisfied with the overall service Onofreo provided from the initial assessment to job completion, including the office staff, who showed extreme patience with my concerns. There were challenges, as this was a replacement AC unit. Despite that, the expertise of everyone involved was clearly evident in every aspect of the instillation. We wouldnt hesitate to recommend the services Onofreo Home Comfort Systems offer.

  • Review 18 (2023-05-01 - Rating: 5)

    I had Onofreo HCS install a new Hydro-air system last year to replace my 35 year old system that kept giving me trouble - Mark, his office staff, and his techs were prompt, professional, and clean. Mark showed up to do his estimate, I got the proposal signed, they pulled the permit, dropped off a check, and in three days I had a brand new system installed. I knew what was going on every step. The install looks great and they provided free cleaning and tune up service afterward. I have also referred my mom to them and she was thrilled with the service. I would highly recommend anyone who needs maintenance or a new system to Onofreo HCS.

  • Review 21 (2024-06-19 - Rating: 5)

    Entire team was professional and courteous. Work was well done and any issues I had were corrected. They also beat competing pricing and went over equipment to make the right decision. Anthony one of their technicians provides outstanding service. Office team answers phone and is responsive. I highly recommend this company.

  • Review 22 (2024-05-10 - Rating: 5)

    We had a new AC system installed. It was great experience from start to finish! From quote to completion was around 2 weeks off season. 4 days in total to complete the job. The crew was great, you can tell they enjoy working together as a team.Onofreo also services our boiler to keep it running top notch. Weve had to call back when we used other companies for various reasons when they have serviced our boiler; will never use another company other than Onofreo for all things heating and cooling.

  • Review 23 (2024-03-11 - Rating: 5)

    Tom, Jack, Brandon, Anthony, Kelly, Shana were great to deal with. The entire Onofreo team works efficiently and effectively to get your project done and follows up on rebates in a timely fashion. We had a heat pump system added to our house with partial ducting as well as a heat pump water heater. Everything was sized correctly (our house is incredibly comfortable) and works perfectly. Pricing was middle of the road, but the service was top notch. No servicing experience yet but Im sure theyll be great. Overall very positive experience.

  • Review 24 (2024-09-28 - Rating: 5)

    Onofreo was very instrumental with its people in getting the job done in my home! Gas conversion, new hot water heater, air and heat central very professionally done!

  • Review 25 (2024-01-09 - Rating: 5)

    Great experience all around. Very informative staff . And Id highly recommend them. The installation crew was very professional. They worked all day and night to get my new heating system up and running. They were also very clean.

  • Review 26 (2024-04-24 - Rating: 5)

    Ive had a wonderful experience with Onofreo Home Comfort Systems. When I needed a new furnace and didnt know how to pay for it, they helped me find a program to help me pay for it. When the furnace started acting funny, because my water pressure it too high theyve taken care of it every time under warranty. Others would have told me it wasnt covered and charged me. I cant say enough wonderful things about this company! So glad my dad found them and recommended them to me!

  • Review 27 (2024-03-12 - Rating: 5)

    If you are thinking of installing a heat pump system, we highly recommend the Onofreo company. The office staff (Shana and Kelly) and sales (Shane) were very good at explaining all the steps involved. Matt and his installation team did a great job removing the old equipment and installing the new system. They also came across as enjoying their work. After the installation, the company sent a technician to make some adjustments that increased our confidence that they stand behind their work.

  • Review 28 (2023-07-10 - Rating: 5)

    I could not be happier with the quality of service we received from Onofreo. We were planning an AC replacement and saved up for a year and lo and behold the furnace crapped out first. Onofreo had worked with us to keep our 25 year old AC limping along until we had the funds and then again when we had to switch gears and replace the furnace first. The furnace works great now!The original system also wasn’t properly sized for an addition put on the house years before we owned it.Onofreo just finished all the work on installing and replacing the AC, making sure everything was properly balanced, etc.The system works great!!! The best the temperature control on this house has functioned in years! The entire staff, from the first phone call to end of install, including the owner, were professional, knowledgeable, kind, and super clean when working inside the house. Plus I got 3 quotes, 3 different times, before getting all this work done and Onofreo was totally reasonable and the least expensive on 2 of 3. The price difference on the 3rd quote wasn’t worth sacrificing the quality of work and people I’d already experienced with Onofreo.I highly recommend this company for anything from repairs all the way to replacement. Just great! Thanks Onofreo!

  • Review 29 (2024-08-06 - Rating: 5)

    When the gentlemen came in they explained to my mom how the units would be installed. They walked through each room with my mom to ensure proper install. Once units were installed they cleaned any areas they came in contact with. The units look GREAT in each room and work perfectly!Thank you for your service.

  • Review 30 (2024-08-19 - Rating: 5)

    Onofreo is and has been wonderful to our family. Also professional and courteous and reasonably priced. They have installed 2 furnaces for us over the past few years at 2 different locations. Being a Real Estate Broker, I have referred them to numerous clients. Top Notch Service!!

  • Review 31 (2024-06-01 - Rating: 5)

    Our previous HVAC Co. got so bad! Long story short they said our 9 year old furnace was not fixable and were forcing us to buy a new furnace. Leaving us without heat or hot water in February for four days. Fortunately the furnace sales rep recommended Mark Onofreo, who along with some of his team were past employees of the previous company!!!They in fact installed our furnace. When Kelly heard that we had been without heat for four days and recognized our name , she sent Anthony out and he immediately repaired our furnace and said it still was in good shape. Anthony was professional and he described in detail everything he had to do.If you need a new HVAC company or need to make a change choose Onofreo Home Comfort Systems, you will be pleasantly pleased!We wish we had known sooner that Mark had started his own company, We would have followed him.

    They came to my house put in my new furnace and air conditioning system. It works great. I could not be happier. Great service for my reliable system

  • Review 33 (2023-10-12 - Rating: 5)

    All of our dealings with Onofreo have been positive. From having a central air conditioning system installed from scratch, to an emergency heating call in the dead of winter, Onofreo has always responded with promptness and professionalism. We also have yearly maintenance checks done of our heating and cooling systems, and they keep us from experiencing any surprise issues. We are also very happy with the office staff. Very friendly, helpful and professional. We highly recommend Onofreo for all of your heating and cooling needs.

  • Review 34 (2024-01-18 - Rating: 5)

    We have had a positive experience with Onofreo. They had installed a new system for us and returned to install a return filter grill. The technician was very neat, respectful and did nice work. We recommend them for your heating and cooling needs!

  • Review 35 (2023-02-20 - Rating: 4)

    Like the famous tag line in the legendary sitcom Cheers state, sometimes you want to go, where everybody knows your name and theyre always glad you came.I spent 6 weeks trying to get a quote from every single big name in the industry, and im still waiting on a call back. Until I found these guys. Not only was i able to have onofreo give me a quote, but walk me through the process of installation, finance, and all other issues as it pertains to my energy conversion project.So I went with them, and they made quick work on the project. Shoot, they even moved my furniture, and that wasnt the job. Quick on service response and / or what I like to call, a technical talk down.Shout out to Shanna and everyone on the team for an amazing conversion to propane at my house.P.s. I dont know anyone there personally, but I believe if you got exceptional service, you should share it so others can experience it too.

  • Review 36 (2024-03-20 - Rating: 5)

    Always prompt and outstanding service at Onofreo! Our old house has needed some TLC over the years, from a finicky hot water heater, to a brand new furnace and other issues in between. Knowledgeable and trustworthy staff have made these inconvenient headaches disappear quickly with fair pricing on top of it all. I highly recommend Onofreo Home Comfort systems to anyone and everyone in need of HVAC work or repairs!

  • Review 37 (2024-12-11 - Rating: 5)

  • Review 38 (2024-01-22 - Rating: 5)

    Onofreo has our highest recommendations. We wanted to replace our very old furnace and central A/C with either a geothermal or air-based heat pump. Ted responded promptly to our request for information and estimates. Deeply knowledgeable, he patiently and thoroughly explained all the factors to consider and produced two detailed proposals. After further research and proposals from other companies, we decided Ted’s proposal was the best. He was easy to reach and generous with his time whenever we had questions, and he carefully supervised and inspected the installation. We were also impressed by the professionalism and friendliness of the installers, Chris and Joe, and the office staff, including Shana. We could not have had better service, and we are completely satisfied with our new heat pump.

  • Review 39 (2023-11-10 - Rating: 5)

    Your company has been phenomenal to work with. I purchased a Mitsubishi mini-split system from you. From the sales person, Shane to the installation people, Joe and Chris, to the Asst. Office Manager, Shana…who seems to hold the whole operation together…your service has been stellar!!! Everything was done when you said it would done, in a timely manner. You had to deal with a condo assoc. that had very stringent guidelines. You addressed all concerns professionally, with grace, patience a desire to satisfy me, the customer, as well as the condo association. I just cannot say enough good things about your company. I recommended our condo association hire you as consultant to assess the installation of the mini-split systems for the complex as a whole. I, certainly, recommend your company to anyone who is interested in installing these systems. You truly are amazing!!! I wish all companies had your work ethic and astonishing customer service!

    I called for my annual heating system service. I was promptly given an appointment. Mark showed up on time and diligently serviced the system, filling me in on what he did and what he found. I have been using Onofreo since my former HVAC company, Bren Air retired a few years ago, and was sold to them. They have never disappointed. I definitely recommend them!

    Onofreo Home Comfort provides exceptional & timely service. Mark Onofreo, owner, and his employees are skilled tradesmen who take pride in their work and service. The service is reasonable, prompt, thorough and masterful. I could not have been more pleased with the work conducted on my home.

  • Review 42 (2023-11-13 - Rating: 5)

    Onofreo has been wonderful. We wanted a new high efficiency (condensing) boiler for heating our house to replace an ancient and inefficient monstrosity, plus a heat-pump water heater to replace an older and less efficient conventional water heater. Andrew was a wonderful sales agent. (Hes not paid by commission, which is a plus.) He was extremely patient in answering our many questions about this fancy technology, discussed numerous options, and was meticulous in measuring and photographing the installation area.Matt, Jeff and Bill did a wonderful job with the installation. They kept things (reasonably) quiet, let us know what theyd be up to, and kept the hot water shutdown very short. They diagnosed and fixed a problem with our pre-existing emergency shutoff. They left the basement cleaner than when they started! Jeff (a different Jeff) had to come out a couple of times after the installation. The first time was to re-connect a wire (for the outdoor reset thermometer) that was disconnected during testing. All follow-up visits were easy to schedule with the very knowledgeable office staff and occurred quickly.

    We built a Net Zero home. Mark Onofreo and his staff were amazing. They were the stars of the project.

We so appreciated their involvement in the project. Thank you Mark and staff!!!

    Lets get this right out the way 1st.5☆s is where I would start!!! I called Onofreo Home Systems about 4 months ago just before Christmas. Our furnace was malfunctioning, working sporadically. They were able to come out the SAME day!!! The tech was able to get us going, but warned it was likely a temporary fix. (Turns out, honest and correct.) Did I mention it was DURING that snow storm?!!! About a week later Home Comfort Systems was at the house installing a Brand New Furnace! Tyvm! Ill be calling them soon after this review to install my Central Air Condenser for the summer. THANKS Mark and Crew!! Affordable and Professional

    We recently had our air conditioning units replaced. From start to finish, the team at Onofreo was responsive, professional, and their bid was very competitive to others we had received.

    We had a propane furnace combustion chamber fail completely on a cold night in December. After receiving a vague high quote for replacement, we called Onofreo. Not only did they offer a price significantly lower, they were able to order the new furnace and replace it within two days, bring our whole system up to current building code standards, and obtain a heating emergency installation permit from our town. Onofreo Home Comfort provides exceptionally prompt, professional service and precious peace of mind!Adding to above 11/26:2024.We have been with Onofreo Home Comfort since they started (actually before then, but that’s a longer story.) Over the years they have installed and maintained two furnaces and three A/C (heat pump) units in ourhouse. We have annual maintenance on all these and have felt our security and comfort really matter to the company. Minor adjustments or function resets were esven handled by phone call or FaceTime with a service expert. Tele-maintenance !!are wearing out and will need future replacement. They have even ordered parts ahead of replacement to be ready as needed.All utilities eventually wear out. We can count on Onofreo to recommend appropriate replacements within our means.Andy WightBranford. CG

    Consummate professionals all around from the staff in the office, quote consultant, and the technicians. Additionally they were very patient with the slow home energy loan process through the state. Highly recommend and I’ll be using them again when I can!

  • Review 53 (2023-10-18 - Rating: 5)

    I’ve used them for years and have always been happy with their service and prices. But my recent experience exceeded all expectations. During a routine maintenance check of my furnace, the technician reported that the CO levels were close to the danger zone, and that I should think about proactively replacing the 14 y.o. furnace. While I was pondering the quote for a new furnace, another technician (who’d serviced the furnace many times before) asked to stop by for a double check. He adjusted a gas valve setting and the CO levels went down to normal levels. Onofreo could have sold me a new furnace before I really needed one and I would have never known, but they instead prioritized me over profits. I applaud their integrity!

    These guys do a great job; they installed an AC and Heating system for us and did a perfect job with it. They were on time, courteous, and very efficient, finishing the job in less time than they had estimated. The systems have been working to perfection, there have been absolutely no problems with them at all. Office staff is great too, they have responded to every call I have made (in my case it has only been to do the annual service maintenances so far) and have efficiently set appointment times up for me.

    High marks for Onofreo Home Comfort Systems, Inc. No high pressure sales pitch. The condition of my old furnace and air conditioning systems was clearly explained and I was provided with multiple options to correct the situation. The work crew arrived on time, were courteous and their work was very professional. They even corrected flaws found in the old setup. The workers left the work areas SPOTLESS, both inside and outside. Before leaving, they explained my new systems and how to properly maintain them. I am very pleased with the service I received and would highly recommend Onofreo Home Comfort Systems to those who need heating and cooling repairs. Great company and excellent work crew. Thank you, Onofreo!

    We just wanted to say thank you for sending out a technician to repair our AC today. You guys arrived fast, fixed it fast and didn’t charge an outrageous price.

Our family will be comfortable. Thanks to you!

    First off, they deserve 5+++ stars. Right from the start I was impressed with their response from my web inquiry as i reached out to 3 different companies that day and the only one to respond to my request was Shana. I never heard from the other two and after speaking with her and setting up an estimate for the job and dealing with Andrew the Comfort Jedi he was awesome and lives up to his nick name. This was the company I was going with and at this point because of the professionalism I received there was no need to deal with anyone else. Everyone was very responsive to my questions along the way weather it was by phone or email. Installation was flawless and completed on time. The guys were courtesy, clean, and punctual. I will use this company in the future and recommend to anyone that asks. Thank again and keep up the excellent work.

    We chose Onofreo to install our new combi-boiler and ductless AC. They were professional, friendly, and always available to answer our many questions throughout the process. We are extremely happy with the end result and would recommend them without hesitation. If you are looking for an honest, reliable and professional company, you couldnt do better than Onofreo.

    I wish I could give more than 5 stars! Onofreo Home Systems came to our rescue when our heat stopped working. They had a tech out within an hour on a Saturday. The team was able to replace our system with an affordable unit. The office personal was friendly, the service people were prompt and followed all safety protocols. When we had questions, the owner called us directly. The entire team is very knowledgeable and I would highly recommend them to family and friends. Thank you Mark and team for the great work!

    Onofreo installed both a new furnace and new AC. Everyone was so helpful, prompt and efficient. Of all the proposals we had for an estimate Shane was the most thorough, friendly and informative. Shana in the office explained the financial aspect professionaly and courteous. On install day we couldn’t have asked for better technicians. Jack, Drew and Pat arrived exactly on time ready to get to work. They were courteous, fast, efficient, professional, competent and friendly. I would highly recommend this company in all departments. We will be using them going forward for all maintenance and service. Great experience with great people.

    Onofreo is an amazing company That is represented by excellent products and professional staff. When I first called them they were extremely responsive to my needs and took care of the initial concerns that I had with an old air conditioning system. They got the old system up and running and put together an extremely comprehensive and thoroughly thought out recommendation for a new air-conditioning and heating system including new thermostats. We excepted their recommendations and had the new AC and heating system installed in a little over one day. The technicians came on time and worked with us to make sure everything was to our satisfaction. I have recommended Onofreo to my neighbors and advised the homeowner is association how satisfied we are with them. We look forward to a long relationship with them. John & Kathy

    This company was amazing to work with! In a time we cant get half of what we need Onofreo went above & beyond to put in our ductless A/C & HEATING system. Parts were hard to get for certain things pertaining to installation. They totally kept us in the loop & found an electrical box needed to upgrade our service. The installation process was exactly what they said it would be. Shania, Mark, John & John I can say thank you enough for being so professional and helpful in this process. We would recommend Onofreo to anyone. We are thrilled with our ACS.Gregg & Dawn French

    Onofreo has proven themselves yet again to be the best in the business. My wife and I went to them a second time, this time to replace our Central AC unit. First of all, they came right out to inspect, then they gave us a price that was much lower than I had expected. The install happened very quickly and everything is perfect. Mark and his team are absolutely wonderful and I cant recommend them highly enough. Truly a first class company all around. If you need work done, this is where you should start. Thank you for another great experience!

  • Review 76 (2022-12-17 - Rating: 5)

    Anthony saved the day. A few weeks ago, my oil company attempted to fix a minor, intermittent problem with the wiring on my oil boiler. By the time they were done, four of my seven zones didnt work (they had all worked before the oil company arrived). They proceeded to tell me that they had nothing to do with the problems and that I had to completely redo my wiring. They then referred me to an electrician who parroted the same information then offered to fix my problems for $4000. Declining this generous offer, I instead contacted Onofreo. When Anthony arrived, he carefully checked over the complex wiring, and instead of throwing his hands up in despair as other companies had done, he diligently traced down the issue. To my wonder and amazement, a short 45 minutes later he had the whole thing working. Total cost: $175. An important lesson here is to make sure the company who maintains your boiler can do both the electrical and the combustion. Many oil companies will only handle the combustion and will do light electrical work, but cant fix a problem when things get hard. Onofreo can maintain the whole system. The next time I have an issue with my boiler, I know who I am going to call.

As I was a customer, Mark came quickly to their house, diagnosed the issue and got them up and running. The temperature outside was dangerous.

    We did a major renovation to a house which needed full HVAC replacement. Mark and the team - from the front office to Jack our expert installer - a first class operation.I dont do reviews, but felt this time warranted it. Mark sat with me and together we figured out how to replaced three older units with two new ones including Heat Pumps and NG Furnace back ups and save 30% over competitors and this was with top line equipment.The team at the house was responsive, friendly and extremely professional. More importantly they were conscientious. Keeping their work neat and at a high standard.I would not hesitate to recommend or use them again. There are a lot of HVAC companies out there - Onofreo is one of the best!As far as I am concerned I would do it all again with them - they are simply trustworthy.

    We recently had to replace our central Air Conditioning and received estimate from various HVAC specialists, including the one we currently have a service contract with. Shane, the sales constant, was by far the most professional, patient, kind, honest, and thorough person that I met with. Not only did he provide excellent options for our current needs, he was also helpful with researching our future heating and cooling needs. He answered every one of our questions by phone and email with such thoughtfulness and competence. The installation team was also really excellent, efficient, and considerate. And the owner, Mark, even had the team come back to make tiny tweaks to make things were perfect. We are so glad we found Onofreo HC and look forward to working with them for years to come.

    Jeffrey Lane came out to give me an estimate. He was friendly, knowledgeable, and patient. He answered all my questions and never pressured me into a decision.He was sensitive to my financial situation and offered me three options, in writing, the same day.The website is top-notch and easy to navigate. And, because Jeffrey knew about available rebates and low interest State of CT loan optionsat https://energizect.com/search, I was able to easily apply online. You can stretch the payments out as far as 11 years, depending on your credit score, making the purchase affordable.Note *** I am in no way affiliated with this company, although I probably sound like I am.The installers took care of everything. My boiler failure was catastrophic, causing steam and soot damage to the entire utility room, including my electrical panel. I was without heat for three weeks, mainly because I had to wait for an insurance adjuster to come out to inspect the damage.Once again, Jeffrey, out of concern for me and my Great Dane, Moose, brought a ceramic heater to me without my even having to ask.The installation process was flawless, including carting away the boiler and hot water heater, which I no longer needed.The office staff was tremendously helpful as well. Shana was efficient and organized. She answered all my questions promptly, helping to make the entire project go smoothly. Because of her, I was able to reply to my insurance company as soon as they requested documentation.Jeffrey and Shana put together the written estimate within hours. It was comprehensive, and my insurance company never once asked me for clarification. Because Onofreos is accredited with the State of Connecticut, not to mention they have a five-star rating, the State of CT loan application was also accepted immediately as well.I also have to give a shout-out to Homesite Insurance Company for their prompt response. and generosity. This was the first claim I have ever submitted, and to be honest, I had no idea what to expect. The insurance adjuster came out while Jim and Jeff were installing the new, highly efficient combo system. Jeff (Aka Keff #3) from Homesite surveyed the damage, took some pictures, and was greeted with great affection by Moose, who is a great judge of character. BTW, Jeff and Jim from Onofreos were also a big hit.Elaine, the insurance adjuster, issued a check within a day or two of receiving the inspection report. She was totally helpful and friendly.For my part, I did quite a lot of research and previously had gotten an estimate from a competitor. They were also highly rated. Their estimate was about the same, and Im sure I would have been satisfied with their service.The main differences, and he reason I chose Onofreos, were:1. Michael, the owner, gave me a $500.00 rebate for signing quickly.2. Jeffrey listened to me. He offered me several options based upon my needs.3. Both my next-door neighbor and my son-in-law had had a lot of issues with the units theyd purchased elsewhere. When I voiced my concerns to Jeffrey, he was empathic and explained that although the model I wanted was more expensive, it was more reliable, and replacement parts were more readily available. Plus, the rebate Mike gave me helped to defray the difference.In the end, I chose a model made in Germany. I wasnt offered a choice with the first company. The only unit they offered was made by the company that made the units that had issues, and parts were difficult to come by.Thanks, everyone!https://www.onofreohomecomfort.com/https://energizect.com/searchhttps://go.homesite.com/

    I had Onofreo install a new AC and Furnace (conversion from oil to propane) in May 2021. I spent a lot of time sorting through the reviews of the best rated companies on Google before choosing them. I could not have been more satisfied with the job they did. They were on time, professional and even came back a second time to answer questions that I didnt know to ask on the day of the installation. I will say Anthony and Giovanni deserve a special mention for their exceptional customer service.

    We called Onofreo Home Comfort Systems on several occasions for service to our Air Conditioner and Home Heating System. Each time, the service representative was very professional in his manor, on time, and before they move forward with any work, they work out an estimate of costs. The service representatives were knowledgeable and understood what repairs were needed. After the work was performed, there was a call the next day to follow-up on the repairs. Costs were reasonable, work was clean for the customer. We now have a service agreement in place and I recommend Onofreo to any future customer.

  • Review 94 (2021-09-21 - Rating: 5)

    Onofreo installed a new central AC unit and air handler for me this summer. I got several quotes, and I chose Onofreo because they 1. were honest about what I needed and really advised against a complicated system! 2. gave me a couple of options and agreed with me about which brands were reliable and which might be overpriced (naming no names!) 3. gave me a fair (not cheap but reasonable!) price 4. were prompt with their estimate and could do the job the soonest 5. are certified installers (this is important for having your warranty certified by the AC unit manufacturers - as I read everywhere, its better to have a basic unit installed well than an expensive unit installed poorly), and 6. the customer service/phone service was very good. The women I talked to on the phone were pleasant, prompt, and knew about my account. They even mailed me an AC rebate form a few weeks later all filled out for me to mail in! In terms of the day of installation, the two gentlemen came on time, were neat, took all the safety precautions I asked, spent quite a bit of time making sure all the fluids and levels were correct, and finished in a day. I would suggest that you throw down a tarp over any hardwood floors as they are carting in a lot of metal equipment over the course of their work. I was really pleased, and happy that I got a 16 Seer unit (more efficient than a 13, but not the SUPER efficient kind) because my summer electric bills seemed maybe $50 lower than last summer per month (1800 SQFT house), which was nice. I would use them again.

    I had my brand new centralized airconditioning installed by Onofreo in May 2022. Shana from the office has been very responsive with my issues, new airconditioning unit has been loosing freon three times already since it was installed, last one was in July this year, they were quick to response taking care of the leak. So far Iam happy with their quick responses but Im hoping they have fixed the issue of leak and loss of freon once and for all. I will review again in the future if this problem will persist. I hope they have truly fixed the issue for good so I can really put my 5 star rating for good. Crossing my fingers at the moment. We shall see.

The install happened much quicker than I anticipated and they were SO clean, I would have never known they were in my house cutting into walls, etc. The system itself is awesome - very quiet and cools down the house super quick.

    Of course on one of the hottest days of the year, the air conditioner quit. We called Onofreo and Jeff responded that he wouldn’t be able to get out until the next day and even that wasn’t guaranteed but he gave us a number of things to try first. Unfortunately none worked but Jeff came the next day and got the job done. It was a holiday weekend too so we were very grateful. He was very polite, helpful, honest and professional unlike some other companies we tried that advertised “emergency service” but then acted like we were inconveniencing them. This is our new go-to company for HVAC and highly recommend!

  • Review 102 (2021-01-12 - Rating: 5)

    Very happy with their work and responsiveness.We purchased our home 1.5 years ago with a 15+ year old AC. This past summer we noticed the AC was not functioning properly. We contacted Onofreo after looking online for HVAC companies and are very happy that we did. A technician came out within a day or two of our call and thoroughly evaluated our unit. He informed us there was a small coolant leak somewhere in the system and that was probably causing the problem. He made a couple of small repairs and refilled our coolant. Prior to doing this he was clear that this may or may not work and at best we had about another year or so out of our AC. The unit did work better for about a week but really wasnt functioning as well as we wanted and so we called back for an estimate for a new unit. Within 2 weeks we had a new AC/furnace. But what really set Onofreo apart was their continued customer service.During the coldest part of the winter we realized our furnace kept shutting off and was not adequately heating our house. I called them in the morning and at 6pm they came out to evaluate. He thought he figured out the problem and made an adjustment but said to call back if it didnt work. This did not solve the problem (after giving it 2 days) and I called them back Friday morning. Another technician came out at 5pm on Friday night and spent 1.5 hours evaluating our unit. He finally and correctly figured out that the unit was fine but the gas flow into our house was low and that there was a clog in our gas line. He stayed at our house while I called the gas company so he could provide any additionally information to ensure they would come out and evaluate the line. The gas company came out that night and agreed that we had a clog and then unclogged the line which led to our heat functioning properly. It also fixed the problem with our stove (which we had thought was just because it was old but turned out it was because the gas pressures were so low).Overall, I could not recommend them more highly. They were polite, professional, and prompt. I am very happy we used Onofreo for our new units.

    We used Onofreo for an oil-to-gas conversion, replacing our old oil furnace with a gas furnace. At the same time, they replaced our A/C unit with a new unit that matches the furnace. Overall, we were very satisfied with our experience with Onofreo. First, they provided a competitive quote, and Shane did an excellent job explaining the ins and outs of the conversion. Shane gave us two quotes, one with a higher cost furnace (2-stage vs 1-stage) and a slightly more efficient A/C. Importantly, when I explained that we were planning on staying in the house for less than 10 years, Shane very quickly recommended the lower cost quote since we would not recoup the cost in energy savings in our time here. Second, Kelly and Shana in the office are unparalleled. The gas company caused scheduling snafus (claimed they installed the service line when they had not), and Kelly went above and beyond to help straighten things out with the gas company. We eventually had to move our installation date back two weeks due to the gas company, and Kelly and Shana somehow finagled the city inspector to agree to an inspection date that they initially said they would not do. I was incredibly impressed with the front office at Onofreo. Finally, the installation itself went very smoothly. They even left our basement cleaner than they had found it. Everything has been running well for the last month or so. I will definitely be using Onofreo for any HVAC servicing in the coming years.

    Very professional and the crew were on time and did the job right. This was a very well coordinated removal of a 20 year old system that required rewiring by electricians etc. Well worth it and with very easy financing and quality work. Will hire again for a mini split in my basement.

    The team was awesome. They worked with my requests and my 1947 constructed home. As you may know, older house have a unique challenge of not being up to current building standards and everything opened up is a surprise. They did a great job and kept our space clean. I highly recommend this group for any of your HVAC needs.

    Onofreo Home Comfort Systems LLC installed a new ductless, mini-split air conditioning system in our home. Very completive pricing when compared with other area contractors. The two installers were Brandan and Levi. They provided high quality work, answered all our questions and made very helpful suggestions for the installation. They were very professional, knowledgeable, personable and friendly and thoroughly cleaned up the worksite at the conclusion of the job. In sum, we highly recommend Onofrio.

    The technician was very polite. He assessed the situation quickly but thoroughly and provided a honest diagnoses. He told me exactly what was wrong and needed to be done and he performed the job well because everything is working perfectly. I will call them for my future needs and recommend them if you do not have a HVAC provider.

    Onofreo was a delight to work with. Their staff is knowledgeable and the installers were impeccable. My home was left as clean they found it, but with two new mini-splits! I will continue to use Onofreo and their services in the future!

    Just had Jeff from Onofreo Home Comfort at my place to service my 25+ year old oil fired boiler. Called before he arrived during the appointment window. Arrived when expected. Most importantly, performed annual maintenance and DID NOT attempt to scare me into replacing my ancient boiler, even though Im well aware that its days are numbered. When it is time to replace the unit, Ill be calling Onofreo.

  • Review 128 (2023-10-01 - Rating: 5)

    Was very pleased with excellent customer service at all levels. The installers accomplished an impressive amount of work in a short amount of time with minimal disruption to the flow of the household.One day after the installation, there was an issue with the hot water. I called and a technician responded immediately. The problem turned out to be the faucets with aerators were so clogged that it restricted water flow and the on-demand hot water will not work if under a certain flow rate. Quickly diagnosed and fixed.

  • Review 129 (2020-07-23 - Rating: 5)

    We scheduled the appointment the day before and were given a four hour window for the technician to arrive. Anthony called within the window to let us know he was on the way. He came shortly thereafter, diagnosed the problem, gave me the price to fix the problem and fixed it after I let him know I wanted to go ahead with the repair. I will use Onofreo Home Comfort Systems again and I recommend them to anyone who could use their services.

    My furnace died a few days before a snow storm. The  team at Onefreo from top to bottom was impeccable and made the process of replacing my AC and furnace stress free. I cannot thank Tommy,Kelly,Jeff and John enough.I wish every business  was conducted and run in the same professional manner. Its the small things that stood out to me that separates Onefreo from the rest.* next day consultation  without pushing for a replacement.*The installers, Jeff and John, worked through their lunch break to ensure my furnace and ac were installed before the storm and an hour earlier than promised.*  clean detailed work.* offering to  drop off space heaters for my family before they go out.* registering my furnace for warranty and a rebate.* reaching out and helping me with the town inspection.A+++++Again, Thank you Onefreo!

    We put in a last minute plea for help after our heat decided to stop working today, on a Sunday of all days. Kelly helped organize it and was very efficient. Anthony arrived so fast, and was very thorough, informative, and professional. He gave us a ton of good suggestions and even helped us figure out how to use our homes humidifier system that we had never touched. Now we have heat again, and we might not get zapped by static electricity so much as a bonus. Thank you for the fantastic service!!

    My four year old ac fan stopped working on one of the hottest days this summer. The original company would not send anyone out but Onofreo was not only super responsive they were also so professional and kind and had the fan working the same afternoon. I will be taking all maintenance in the future to Onofreo.

    I loved Everything about this company! From my first phone call with the office staff to the installation (had ac and water heater done at different times), and clean up. Every person involved was efficient, knowledgeable and took time to be sure everything was working properly. I would also add that with my water heater, it was an “emergency, “ and they did everything to get a technician out ASAP to make sure it was taken care of.

  • Review 144 (2020-02-25 - Rating: 5)

    When my furnace stopped working I panicked knowing I have small children in my home and it was 19° outside. I have used a small company in Branford for years that over time I lost faith, trust, and interest in using due to their constant change of staff and inconsistencies with diagnosing issues with my hvac systems but against my better judgement I called them to come out and look at my furnace. Them knowing me well and the fact that I have small children, not only were they in-compassionate but they also didn’t return my call promptly to schedule a tech to come out. The woman took my information down and said she’d have to get back to me as they have a lot of “no-heat” calls already and doesn’t know when they could possibly get to me. So, I had to turn elsewhere. I found the number of Onofreo Home Comfort Systems through an ad on Facebook and decided to give them a call. I noticed an immediate difference starting with the staff that answered my phone call in comparison to the old company. A woman named Kelly was warm, welcoming, professional, and genuinely concerned for the needs of myself and my children. We talked a bit about the history of the furnace (age, previous issues, etc., she went through a few quick troubleshooting issues over the phone in order to eliminate any small possibilities or quick fixes that we wouldn’t need a tech for and since we didn’t get anywhere with that she promised to get a tech out to me as soon as possible. She put my mind at ease and made me feel a lot more calm. I was FLOORED when a tech knocked on my door just two hours later!! The tech was also friendly, professional, and wanted to get right to the bottom of the issue. May I also add that he arrived in uniform and the truck he was driving was clearly marked with their business name so I felt at ease knowing it was the company I called. The tech immediately got to work on diagnosing the issue, which just so happened to be a quick pop out and pop in part that started my furnace right up and put me at ease knowing my children would not be cold. I thanked the tech and he told me to call the office right away should any additional issues occur and he’ll be sure to come right out. Needless to say I will be using Onofreo Home Comfort Systems for all of my future hvac needs.

    My furnace broke down on a Saturday night, of course, after calling around to multiple companies, the only one to call back was Onofreos. Enter Anthony, my night in shining armor, he happy agreed to come to and help address my heating problems. In no time at all he had my furnace up and running. I was impressed with his professionalism and knowledge so i decided to purchase a service contract with him. Im looking forward to working with Onofreos and Anthony again in the future.

    Anthony called prior to the visit. Arrived on time & found a capacitor was bad on our compressor.
