    I selected Diamond Air Services from 4 other highly rated companies, and Im glad I did. The entire experience was positive. The team arrived on time and replaced my old equipment in a few hours without any issues. I feel that I can trust this companys workmanship and I highly recommend them.

    Diamond Air replaced the Air conditioner for our house with a brand new Carrier SEER 17 unit and we couldnt be happier. From the first phone call to set up a consultation and then meeting with Anthony to determine the best unit to fit our needs, to working with Bobby and Mike on the install team, dealing with Diamond Air was quite pleasant. Our installers Mike and Bobby were very knowledgeable. They answered any questions we had and worked seamlessly until the job was done. They were focused , efficient, and clean. When installation was complete, Bobby showed us how to use the new thermostat and even helped us sink it to our phones for easy control. Our house is so cool now! If you need any help with your heating or air, call Diamond Air. They are a great company and we highly recommend them!

    The DIAMOND AIR - HEATING & AIR CONDITIONING Team is knowledgeable and professional. Mike is especially meticulous and dedicated to quality. I trust Diamond so much I had them install an HVAC system at my Mom’s. Now they are working on my sister’s home.

    Mike came out to check out my ac. He was on time, friendly and knowledgeable about the system I have. He answered all my questions and recommended I do somethings that could help out keeping my place cooler. He showed me where and how to replace my filter. I recommend Mike and Diamond Air Services to everyone. I will definitely use them again in the future if needed.

  • Review 5 (2024-09-06 - Rating: 5)

    Mike was great helping me out with my ac thermostat setup. He walked me through all the app setup as well and showed me where to find phone numbers in case I need to contact Diamond Air for questions. A great experience from the appointment making to the final installment!

    We been working with Howie from Diamond air service for more than 2 years. All work done was superior! Fair price, compared to other companies. We are very happy with them. We used them for yearly maintenance services, and repairs. We are so grateful for them.Thank you team Diamond!

  • Review 7 (2024-11-09 - Rating: 5)

    I was very pleased with the installation of my HVAC units by Diamond Air Services about two years ago. However, I had a minor issue with some of the air duct insulation and I called Anthony at Diamond Air Services. He had no hesitation with sending a guy out to take care of it. The next day, Mac shows up right on schedule and was happy to take care of the repair. Mac did a wonderful job with no charge. I respect Diamond Air Services for standing behind their work as they promised they would.

  • Review 8 (2023-05-20 - Rating: 5)

    First and foremost, Howie is amazing! I contracted his company to remove and replace my Heating/AC unit from my rooftop. In addition, he also reconstructed and engineered a new platform for the roof. The existing platform was over 30 years old in a 70-year-old home. He also took on this complicated project knowing he needed to coordinate with my roofing contractor as well, and vice versa. Because I had 2 projects that needed to start at the same time, Howie was super flexible and patient with me. He always called, texted and emailed me over a 10-week time period to stay in touch for scheduling. This year, we had a very wet season, and, it goes without saying that this delayed the project for so long. When the work finally started, Howie and his team; Mac, Bobby, and Carl, had a sense of urgency to complete it, that I cant overstate it. They are professional, courteous, clean, on time, smart and very detailed. His team blended in very well with the roofing team. And, last but not least, in Howies pricing, in comparison to his competitors, he offered a super great deal for an awesome Heating/AC unit brand and workmanship. Look at the posted images and youll see what I mean. Btw, it feels amazing inside my home now. A huge improvement! I cant wait for this summer to come! 5 stars!

    We had Diamond Air Service install our carrier in 2021, and recently, the fan outside our house stopped spinning. I texted Anthony this morning, and he replied instantly. Within an hour, he sent two technicians to fix it. Everything is now working perfectly. I’m very happy with their fast and efficient customer service!

  • Review 10 (2024-10-04 - Rating: 5)

    Diamond Air has always been quick to respond and their techs always do a great job troubleshooting the problem with my HVAC and AC Condensers. I have used them for 3+ years now and will continue to recommend them to friends and family within their service area!

  • Review 11 (2024-10-01 - Rating: 5)

    This was a requested Annual Maintenance Check Up.Diamond Air sent a photo of my technician when he was on his way. He arrived on time. Worked quickly & professionally. Check in the attic and our outdoor AC. Also check the air filter and replace it.

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

    Howie and the rest of the team were very professional. Day one- peeled away old roofing, day two-took off the old unit, installed the new one. Day three-re-roofed. Done! So good!Called to find out why the heater wouldn’t come on. Came out in one day. , easy fix. Great service!!!Called due to water leaking from roof. Came out right away, patched up the area on the roof. Prompt and happy with service

  • Review 13 (2024-06-05 - Rating: 5)

    Anthony and his team were awesome from start to finish. Upfront pricing that beat out multiple competitors and no pressure on sales. Communication was excellent. The crew who came to install 2 complete hvac units were professional and friendly. They kept my house clean with drop cloths and picked up afterwards. Would highly recommend Diamond Air and use them again the future.

  • Review 14 (2024-08-07 - Rating: 5)

    I was referred to your AC services by my sister and Howie was the main person that I interacted with. After reviewing several quotes from other AC companies, yours was the most transparent and provided clear information regarding the cost and necessary repairs, supported by photographic evidence.I intend to utilize your services for any future needs and hope your business prospers!Thank you!

  • Review 15 (2024-07-02 - Rating: 5)

    Diamond air was great! Anthony’s communication with me was fantastic and he & his team were a pleasure to work with. Hopefully we won’t have any big issues to have to call them again, but if anyone needs a rec in the area, I’d recommend Diamond without hesitation.

  • Review 16 (2024-12-12 - Rating: 5)

    Diamond replaced the ducting in the attic of my very old home. The new ducting improves the A/C performance now and will comply with the 30 yr old roof and A/C when needed. 5 STARS

  • Review 17 (2024-06-07 - Rating: 5)

    Complete professional, and super nice staff. Tiffany that does the booking and asks questions about your needs. Was extremely knowledgeable and answered all my questions and addressed my concerns. The 2 technicians who came to my home to service the HVAC were extremely excellent at their job and very people friendly. Will inspected everything first and informed me on every aspect of what they were going to do. Carl who cleaned the ducts took time to make sure everything was done correctly. We also had our dryer vent looked at. Ashton went over and above making sure the area behind our stackable washer/dry was cleaned. He also had wonderful people skills and was a great communicator.In my opinion this company is at the top of their game with the work. The technicians really mad me know that they listened and did their work accordingly. Will definitely have them do yearly maintenance on our HVAC system from now on!Thank you Will, Carl, Ashton, and Diamond Air for your service!!

  • Review 18 (2024-03-26 - Rating: 5)

    Anthony came out and was a Great guy. His price and service was outstanding. His installers Aldo and Will were very professional and knowledgeable about their work.I highly recommend Diamond Air Services for your heating and air.

  • Review 19 (2024-04-14 - Rating: 5)

    Mac came out to perform a complete checkout of our 3 AC units before summer weather hits and did a professional and thorough job. He explained what he was doing and why and I feel confident that our AC system is ready for the summer. I plan to continue to use Diamond Air Services for any future needs that we may have.

  • Review 20 (2024-04-09 - Rating: 5)

    Entire experience was OUTSTANDING! I got quotes from three different companies and Anthony from Diamond Air was the best for equipment options and price. The installation crew (Aldo, Oscar, Will & Carl), were professional, and courteous, while providing quality craftmanship services. They kept me informed on the status of their work. Completed work within the promised time schedule. Upon completion work area was clean.THANK YOU, DIAMOND AIR.

  • Review 21 (2024-05-16 - Rating: 5)

    Received a quote from Anthony for a full AC and furnace change. He was very polite and explained to us everything that needed done. A very detailed quote was sent. Not the cheapest but not the most expensive. Job was done by the beginning of next week. Crew was very polite. Only issue was cleaning after the project. There was some messed left. Anthony came and did a final walkthrough and easily fixed the next day! Installation, HERS and city inspection all done within the week. Awesome customer service!! Highly recommend!

  • Review 22 (2023-04-07 - Rating: 5)

    The tape unraveled from the duct that flows air to the house. I called Diamond Air and was able to schedule a same day appointment. Service Tech Joey Carroll was extremely professional and went the extra-mile to ensure the duct was thoroughly taped. Also, as a courtesy he checked my HVac system to ensure all was working well. Joey was extremely acknowledgeable and helpful. I would definitely recommend this company.

  • Review 23 (2024-06-12 - Rating: 5)

    Diamond Air is absolutely the best team for immediate responsiveness and professional AC service! Howie and the team are great at what they do and most importantly do it with business honor instead of many businesses that try and upsell. Highly recommended!!!

  • Review 24 (2024-04-10 - Rating: 5)

    Diamond Air always provides friendly, reliable and affordable service. They installed our heat pump at a great price with unbeatable financing. Theyve earned my familys trust to keep us comfortable year-round in our home.

  • Review 25 (2024-10-10 - Rating: 5)

    Will and his partner were very helpful and the air quality feels different already. Would recommend them to anyone looking for dry and air vent cleaning!

  • Review 26 (2023-12-27 - Rating: 5)

    Diamond Air Services deserved more than 5 stars review! Service call a couple days ago for furnace issue. Anthony M. immediately scheduled one of the technicians, Mac to come out to inspect the unit on the next day. Mac was very knowledgeable, courteous, and punctual. After diagnosed, a new part was needed. New part arrived a couple days later and new appointment was scheduled. Mac and Will came out to repair the unit in a just a couple hours. Their service was efficient. My furnace is back on running. Im extremely satisfied. Yay.... :) Great company with excellent staff from Anthony, Mac, Tiffany and Will. Whats a good team. Last but not least, it was very reasonable price. Thank you so much for your service and will definitely recommend to friends and family. Excellent Experience.

  • Review 27 (2024-08-20 - Rating: 5)

    Great company. They get back to your AC needs in a very timely manner. Highly recommend them. Thanks Howie.

  • Review 28 (2024-06-07 - Rating: 5)

    I didn’t get all the guys’s names that serviced our house today, but Will and company were great. They cleaned my air ducts and also cleaned and replaced the dryer vent. They let me know when they were on route and throughout the entire process kept me up to date with what they were doing. I worked from home today and they were able to get my room done first so I can get back to work. They wore foot booties and placed plastic around the areas they were working on. They even had a dust pan and broom to clean up any little debris that might not have fell on the plastic. I’m slightly OCD when it comes to having things cleaned and I was so happy they did all that. Oh let’s not forget Tiffany who took my initial call and went over the process with me regarding getting my air ducts cleaned and a quote. I didn’t feel pressured at all. Definitely recommend Diamond Air Services for your HVAC needs!

  • Review 29 (2023-11-21 - Rating: 5)

    Mac did a great job with our service. Again another great job and another great company. Thanks Anthony and Mac for a 5 star service. Highly recommend this company!!

  • Review 30 (2024-07-22 - Rating: 5)

    As my last experience, excellent and professional customer service. Bobby was super respectful to the property and went above and beyond to answer all my questions in detail. My permanent AC go to company for maintenance and repairs!

  • Review 31 (2023-06-15 - Rating: 5)

    My HVAC unit is pretty old and wasn’t really functioning properly, 30+ years old and so I needed an honest opinion if it was time to upgrade. Called up Diamond Air services to check it out and spoke to Anthony to set up a schedule, Joey showed up and diagnosed the whole unit and gave me an intelligent honest opinion. We decided to upgrade and Anthony gave me a thorough breakdown on how the process goes. Scheduled the week after for install and would take 2 days. On the day of install the crew showed up, Bobby, Mike, I believe (Sean and Carl? And another person) I’m sorry if I didn’t remember the names correctly. They were courteous, efficient, and fast. One crew worked outside on the AC and another in the attic for the heater/duct work. They were done on time and did an awesome job. The AC was finally blowing nice cool air all over the house, It felt great. There was a slight issue with the heater fuse and primary drain being clogged, so they rescheduled to come back and fix it. Joey showed up to do the fuse install and fixed the main drain clogged and everything is now working properly. Overall Diamond Air services did an excellent job and I would definitely use their service again. If you ever need help, Anthony is the person to call. Thank you Diamond Air Service for the awesome job!!Edit: update, still had issues with the AC primary/secondary drainage and Mac did an awesome job diagnosing and fixing the problem.

  • Review 32 (2024-07-11 - Rating: 5)

    Professional Technician Harvey explained what the problem was and helped me to understand the issue. I felt comfortable with him and he was very patient and kind! Thank you so much for another awesome experience with Diamond HVAC! Your technician is definitely an asset to your company! :)

    We recently had our 30 year old furnace replaced by Diamond Air. Anthony was extremely helpful with answering all of our questions and concerns and providing us with the best affordable options. The installers Aldo and Oskar, who were very professional, they made sure to prep the area for work and completed the job in a timely manner. We were very pleased with the service and would definitely recommend Diamond Air.

  • Review 38 (2023-12-07 - Rating: 5)

    Had a new 4-ton HVAC system installed this year, not only were their prices the best, so was their service. Every employee and technician treats your house as it if were their house. Every single person went above and beyond. The personal touches and attention to detail is something Id thought had gone the way of the dodo. Id recommend them to everyone who needs HVAC replacement or services. Diamond Air is the best, and only has the best technicians, the best employees, the best installs, and the best service!

  • Review 39 (2024-08-16 - Rating: 5)

    Oscar was great. 10/10. Fixed the problem, knew exactly where to look for it, and did it in a timely and efficient manner. He was also upfront about pricing, and the price was more than fair!

    I had such a good experience today with Diamond Air. Mac Apodaca came to do services on the AC/ heater and he explained how my thermostat needed batteries and he was super helpful and showed me how to maintain my filter. Thank you so much Mac you were such a big help and I can’t wait to use my AC/ heater.

  • Review 41 (2023-12-08 - Rating: 5)

    So far, so good. Mac, very nice and polite, came out and went through everything on the furnace. Looks like a motor problem so will have to return. Hopefully that visit will go well too. Update: everything good. Diamond called within 48 hours to schedule the repair. Mac came out and replaced the motor. He was on time and completed the work in less than expected time. Everything works as it should. When I asked about routine maintenance, Mac didnt try to sell me on every 6 months etc. He gave me maintenance recommendations and assured me that I am now a Diamond customer and their priority is customer satisfaction. I wont be calling anyone else, and will recommend Diamond to all my friends.

  • Review 42 (2023-12-03 - Rating: 5)

    Diamond Air is awesome! Anthony & Steve are professional, personable and knowledgeable. They’re timely arrival, quick, efficient appraisal of our situation & reasonable estimate made us feel comfortable with them and their work was thorough. We highly recommend them.

  • Review 43 (2023-01-13 - Rating: 5)

    Our furnace died a few days before Christmas--the worst timing ever! I saw how good the reviews were for Diamond Air Services, so I gave them a call. Anthony was here within the hour, I had an estimate that day, and we were getting a new heating system installed within a few days. Excellent price, superb customer service, hes on-time and communicates, and his team was spectacular, clean, and professional. We could NOT have asked for anything else. Thank you, Diamond! We have found our forever service provider in you!

    Diamond Air did a super job replacing my furnace, air conditioner, hot water heater, and a fire door with new equipment. They showed up on time, communicated effectively and frequently, answered all of my questions, did a high quality installation, and left the work site immaculate. The best contractor Ive had the pleasure to work with.

  • Review 48 (2024-04-09 - Rating: 5)

    I found Diamond Air on Yelp and hired because of the great reviews I read there. Easy to schedule an appointment. Mac came out to tune-up my Lennox HVAC before it started getting hot in spring/summer. Very punctual, communicated when he was on the way. Super nice, professional, knowledgeable, walked me thru step by step what he was doing and gave me easy recommendations on how to keep my HVAC in tip top shape. Highly recommend Mac and Diamond Air and will call them again in the future for my HVAC needs.

  • Review 49 (2023-08-07 - Rating: 5)

    My A/C unit went out and Anthony was able to get a tech out in 4-5 hrs. Mac was our service tech. He was on time, professional and knowledgeable. He walked me through everything that he was going to do to fix the issue on both units. Extremely honest, clean and got the job done fast and A/C was running in a few hours.My appointment time was from 1:30-2:30. I received a call from Anthony the owner just to let me know that Mac might be a few minutes behind but he showed up in my hour window. Communication was something you typically do not get these days.Diamond Air will be my first call if I am in need for a service.

  • Review 50 (2023-06-14 - Rating: 5)

    This is my second time using Diamond Air for AC services. The first time was for maintenance two months ago and this time it was to repair the AC unit. Both times have been really good experiences for me. Theyre very respectful, punctual, and willing to explain details.Joey Carroll was the technician that came out this time and he did a phenomenal job taking care of my unit in a timely manner. He knew I was curious and wanted to see what the unit looked like after he opened it up; he took the time to call me when he had it opened and explained in detail what he was doing. I will never be able to do the work that he does (he has 11 years of experience), but I appreciate knowing how the work is done in theory. He also gave me more info about how else I can continue to maintain my current unit, so that it continues to last.

  • Review 51 (2023-09-18 - Rating: 5)

    I recently had Mac service my AC unit, and it was an exceptional experience from start to finish. Macs punctuality, detailed explanations, and professionalism were truly impressive. He kept the work area clean and even went the extra mile by cleaning the condensers and replacing the air filters as part of his service.Mac ensured my AC was not only serviced but also running at its best. Im thrilled with the results and highly recommend Mac for any AC needs. His commitment to excellence sets him apart in the field, and I wont hesitate to call on him again in the future.

    It is my second time working with Diamond Air Services and I truly could not be more impress with their caliber of expertise and work ethics. Unfortunately for other companies, you truly set the bar high, but Im happy to be at the receiving end of such stellar service. Thank you so much to both Mac and Anthony for going above and beyond in resolving my A/C issue. Mac Apodaca came out to fix my A/C unit that another company tech attempted to fix, but was unable to do so in a timely manner. Mac is very skilled at what he does and very professional. He was very thorough in his inspection and was able to pin point on the problem without any unnecessary delays. He is also very personable which made the interaction very pleasant. You cant go wrong in picking this company and better yet in requesting Mac.

    My A/C unit, which was installed by Diamond Air Services, was not cooling after the first summer. I called them and made an appointment one day later. The service technician arrived on time, checked the unit, and concluded the coolant level was low. Since the installation was under warranty, they added coolant and the service was free. The people at this company are friendly and they stand behind their work. Thanks!I had a follow up call since my A/C was not cooling again. The technician added coolant to keep me cool during the next hot week. He will come next Friday to do a leak detection test and fix the issue.This time, Diamond Air Services is attempting to fix the coolant leak by adding more coolant which includes a sealant. We will wait and see if that corrects the problem. The technician who came by was on-time, friendly, performed the upgrade, and checked the system before he left. Overall, Diamond Air Services has a good staff.

    Very kind and efficient. Anthony was easy to work with, very informative and quick to schedule and appointment. Steve serviced our home and was very informative and kind as well. We enjoyed seeing the before and after pictures! Such a great clean up process as well when they packed everything up before they left. Will definitely be returning in the future. They were referred to us by my neighbor and I will definitely be sharing this referral with other friends and family.Thank you Diamond Air!

  • Review 61 (2022-07-01 - Rating: 5)

    Diamond installed an all-new AC & heating system in my home, after my legacy system finally gave out after many years of hard use. They were very professional and responsive from day one. They arranged interest-free financing for me the same day I called, and began installation the very next day. The crew arrived right on time, and treated me and my home very respectively. It took a couple of days to install when some unexpected fitment issues arose, but they always kept me informed and did what they said they would do, when they promised. After installation I had a couple of issues with the thermostat and a breaker, but they came right back and addressed both issues quickly, at no extra charge to me. I am very satisfied with the product and impressed by their commitment to stand by their work. For sure this was a bigger expense for me than I had originally hoped, but Diamond exceeded my expectations by making it as fast, easy and financially practical as reasonably possible. My family and I expect to be reaping the benefits of their hard work for many, many years to come!

    I would most definitely recommend Howie of Diamond Air Services for all of your AC needs! Howie is quick to respond, timely, and is extremely knowledgeable. He even gave me tips on how to ensure that my unit runs well moving forward. I will continue to use their services and I cannot recommend Howie enough!

  • Review 63 (2022-04-23 - Rating: 5)

    Diamond Air Services exceeded all of my expectations and were a wonderful company to work with! They were accommodating, professional, honest, on time, and a quoted us a fair price. We dreaded finding someone to install our AC & heating due to bad experiences in the past but they were great and alleviated any fears. They were able to completely replace and install everything within 2 days and they came out a week after our first call and consultation. I highly recommend them to anyone looking for anything AC/heating or duct related. :)

    Mac visited with me and my father today. He reviewed our AC system and whole house fan and explained how they work and what should happen going forward.

    I have an old AC that I scheduled maintenance work for with a different company. They said that it probably should be replaced. I received a quote but wanted to get a couple other quotes. I called Anthony from Diamond Air Services and when he came out, he said the unit was still good and maintenance would be sufficient. Joey came out replaced a worn compressor part, cleaned up the condenser, and recharged the refrigerant and got the unit blowing cold. Thanks Anthony, Joey and Diamond Air Services!

    Oscar was at my house first thing in the morning. Very pleasant and professional. When he diagnosed the problem as a component replacement, I immediately thought it would be like dealing with a car dealership, i.e. headache. Not the case at all! Oscar was back 20 minutes later, fixed the issue and my heater was back up and running. These guys (Diamond Air Services) are the real deal!

    I rarely give any reviews online, however, I felt that these guys need a review of the great work they have done.First of all, the Diamond Air Customer Service is beyond awesome. I read a lot about their customer service in yelp and other places and it was all great which encouraged me to contract them. When they came for installation, they missed up on few things but quickly apologized and fixed the issue immediately. Few months, after installing the new system (AC and Heater), we had issues with the gas furnace. Once again, they showed up immediately and fixed the issue, and bought the needed parts. All this was done with great professionalism and welcoming customer service. Forgot to say that before I install the system, there was a tough heat wave in California (Mid to end of July). They offered to come and fix some of my 25 years old system to get me going through the heatwave until they can come to replace the system. They did all this for free!!Thank you, Anthony and all the team at Diamond Air

    The people were very nice, professional and responsive. There were 5 or 6 people sho in up on time and started work right away. They replaced our furnace and condenser units as well as thermostat. They came on time and finished everything in a day including cleaning of the duct and replace all the vents. Price was also very reasonable. I recommend this company. I will use them for the maintenance.

  • Review 76 (2024-08-30 - Rating: 5)

    Allow me to express how my experience with Diamond Air has been nothing less than top notch. From first call to the office, to receiving a very quick appointment (Next day), to a return call and confirmation of the scheduled appoint, then to top it office, Anthony (The man himself) calls me to inquire my issues. After explaining the problem, Anthony tell me he has a cancellation and Mac (Great Guy) was about 20 mins out.Hell, who could ask for anything better than that. From the time I receive the installation of my new unit last year to this very day, Diamond Air had been very responsive each time I have called them, and it has not been many. I have and will continue to recommend them for any and every type of AC/Heating problem I have.Lastly, Mac, this guy is the greatest. He was very professional, funny, engaging, and most so, carrying about my needs as customer. I did not feel rushed, nor did he do a rush job. When it first checked out the system, he immediately determine the problem, fixed then check to make sure everything was working properly before leaving. He provided me with suggestion on ways to set my temperature for best result of both system.Thank you all. Im cool now. lol

    I had to get a brand new unit as my AC finally died after 30 years. Considering I am new to HVAC replacements I had 4 quotes done. Anthony showed up and listened to my needs. Instead of upselling and explaining why I need the fancier unit, he explained why I didn’t need it. He explained what work could be delayed and showed me what he’s seeing. A stark contrast to the other companies who pushed for the high end stuff with the reasoning - why not, we can finance it. On installation day, Mike and his team came and I can really see they took the time to do everything right. I would highly recommend and would use this company again.

    I hired Diamond Air Service for my entire houses air duct cleaning last December, the crews were prompt and efficient. This year, I called Diamond Air Service again for different issues, just because they gave me good impression last year. The technician Bobby was sent to my house for diagnosis on my old HVAC/AC, the heater doesnt work, the AC is not cool, so Bobby quickly fixed the AC issue, but suggested he can fix my heater first instead of replace my old entire system which I think he is very honest about this advise. When the part arrived, Bobby went ahead to repair my old heater, and their company policy is if this repairing doesnt work out in the future, they will apply this repairing cost toward the futures new system cost which I think it is a very fair, reasonable and thoughtful policy. Thank you to the owner Anthony, and his crews. I will definitely refer this Diamond Air Service to my friends and relatives.

    I have never been totally pleased with any air and heating company in my 40 years of home ownership. Until now. After reading reviews, I decided to try Diamond Air, really just figuring I had nothing to lose at this point. I was immediately impressed with the amount of information I received on the phone (she told me what to look for so I would already have an idea of what might come from the estimate). I had to wait two weeks for Howie to come, but the wait was worth it. He immediately confirmed what my compressor needed (the woman on the phone was correct) gave me an estimate in writing and scheduled Brendon to come the next day. Brendon explained to me why the compressor had a leak in the first place, did the work, and I gave him a check (even though I was told I could wait for a bill). That same day, Howie called to inform me that I had OVERPAID, because they did not use all the refrigerant that was included in the estimate. He said I would be getting a refund for the difference in the mail. Again, quite impressive. Now I wish Diamond Air did other home services than just heating and air, because this level of workmanship and integrity is becoming quite rare.

    We hired Diamond Air Services to replace our AC unit in the middle of the summer. Anthony came for the initial inspection and explained to us what we needed and what we didn’t need. He sent us a written estimate of the proposal that afternoon. We had received several other estimates that were thousands more and some that were cheaper. However, we decided to go with Anthony because he made us feel comfortable throughout the entire process explaining and answering any questions we had. The price was also very reasonable.Howie, Albert and their team members installed the new unit in quick time. Howie was there throughout the entire process to make sure we passed city inspection.The story doesn’t end there. I had some issues with passing city inspection with electrical work completed by a different company (Yelp 4 1/2 star company). Owner refused and finally admitted he did not have the capabilities to finish the job to pass inspection. After explaining the issue to Howie, he volunteered to help me resolve the issues. He was a man of his words. He worked with the city over several months and we finally passed inspection. We couldn’t have done it without Howie’s help.We are more than satisfied with their professionalism and kindness.Anthony, Howie and their entire crew are awesome. I highly recommend this company to anyone needing HVAC support .

    Since my HVAC system is over 25 years old and costing a lot $$ in summer and winter, I decided it was time to replace the entire system. I received two quotes and decided to go with Diamond Air Services since I had a great experience with them before.I reached out to Howie as he was my point of contact before. Howie put me in touch with Anthony, Customer Service Manager. Anthony called me on the same day and made an appointment to come out on that Saturday morning. Surprisingly, both Anthony and Howie came out. They looked at the old system, the attic (air ducts), and the vents. Both Anthony and Howie were extremely professional and friendly as always.Anthony provided two quotes (Goodman Vs. Carrier) that same afternoon. I had questions regarding the quotes and Anthony answered my call on a Saturday afternoon!You can’t go wrong with Diamond Air Services as they will NEVER upsell you anything you don’t need. This company is very honest and customer satisfaction is their priority.I decided to go with Carrier 5-ton 16 Seer and we scheduled the installation date. Anthony called me last week to see if I would want to move my installation date up since they had a gap. Unfortunately, it didn’t work with my work schedule, so I kept my original installation date.Howie came out the day before to take more measurements and walked me through the process of the installation day.Today was the big day and the entire experience was nothing but PLEASANT!! Anthony arrived bright early and again, walked me through the process. Shortly after, Mike, Albert, and two other gentlemen arrived. Everyone was professional and friendly. You can tell this company treats their employees right because everyone seemed very happy!The installation took less time than expected. Mike was very patient and explained everything thoroughly. He installed the Nest Learning Thermostat, showed me how to use it, and even helped me program it on my phone.I am extremely pleased with my new HVAC system. It’s nice to have a quiet system and my home cools fast now!I want to thank Anthony, Howie, Mike, Albert, and the other two gentlemen for making this experience so pleasant.I again, strongly recommend Diamond Air Services for any AC/Air Ducts/Furnace needs. It makes a HUGE difference when you are treated with high respect and world-class customer service!

  • Review 129 (2020-12-10 - Rating: 5)

    I had some issue in my AC that a previous small HVAC company came to inspect. The other company didnt try very hard to find the problem and I ended up paying for a recharge that died out at the end of that summer. The next summer, I limped along on a portable system because I was so loathe to call another HVAC company and pay 500 for a recharge and no effort. That was a hot and sweaty mistake for me. This year I called Diamond Air and they were able to trace it back to a bad gasket within 30 minutes.Diamond Airs communication, engagement, payment, and feedback were top notch and equivalent to that of a very long time successful corporate big name entity. At the same time, the tech engagement felt like a very small town know-you-by-name business. I dont know what it is but it felt like they found some secret way to toe the line and be best of both worlds.My tech came out on time, wearing a mask the whole engagement (early days of Covid) and fixed the issue that the other local competing small business failed to address 2 years before. It cost me less in TOTAL than the other guy charged just for a recharge without fixing the problem. My issue is actually resolved this time!Beyond the service, Diamond volunteered a discount to me after switching my appointment earlier by an hour and then being unable to meet the earlier appointment. Instead they arrived at the original appointment time. There was no inconvenience on my part and no need for them to give me the discount but they did it just as a professional courtesy anyway. I wasnt able to remove the discount because it was already applied to the invoice within their electronic payment system. The best I can do is give them this review:They will blow you away with their service and that air will be cool, crisp, and temperature checked by an IR scanner before they take their ladder back to the car.

I had vetted several HVAC companies, some were high pressured sale pitch rep that wouldnt leave my house unless I signed on the dotted line. I was totally annoyed and asked them to leave. When Anthony came to look at my ageing HVAC system, he gave his honest assessment and provided a list of options. His crew handled themselves with professionalism and were easy to communicate with. The job was done quickly and efficiently. I had the city permit officer come by to look at their work and confirmed that the installation met city code and regulations. Hire them.

    Apple Stores sure are pretty, right? Guess who pays for them? Their customers. And thru the eyeballs. DIAMOND doesnt stick flyers in your mailbox and billboards everywhere. Which is how I got an entire new system for my condo for a 3rd off the big competitor. And these guys are beyond professional. If youre not getting their quote youre throwing money out the window. Trust me.

    Anthony is a great guy and very honest. Initially, they quote me for the heater logic board but found out that the actual problem is the flames sensor. This lower cost tremendously. I definitely love their services and true honesty!

    The technician from Diamond Air (I forgot his name - sorry) had been to our home before after we had just purchased it, and what was cool is that he remembered us. His service and professionalism were still the same as when we first met him. He came out to service our 3 yr old HVAC system because it wasnt blowing cold air. I really like this company so I will start using them on an annual basis to service the HVAC.

    Diamond Air installed my HVAC system almost 5 years ago. I have been using them for my annual maintenance because they are reliable and provide good quality work. This time my compressor does not work. I can hear the humming noice but the fan does not spin. Checked both fuse and circuit breaker, and they are fine. I contacted Diamond Air in the evening, and they were able to send a technician out the next day. I really appreciate for a quick response during this hot summer. The technician was so happened is the Diamond Air owner, Howie. He did a quick check and found out I have a bad capacitor. No further issue was found. Howie stayed a little longer and made sure the compressor is working properly before he left. Good service!

  • Review 194 (2024-03-29 - Rating: 5)

    My mom has severe asthma and these Santa Ana winds really triggered it badly that she had to be hospitalized. So I did what any child would do... get a air purifier and deep clean the house. But deep down, I knew that wasnt enough. So I had the idea of getting our air ducts cleaned out since its been forever. Yelp was my go-to and I researched around based on reviews or worksmanship, knowledge, and the availability of appointments. I found Diamond Air services and they came out the next day! Will and Dylan were great! They were courteous, polite and made sure we understand everything going on. Every step of the way. I would definitely recommend this company and will refer them to our neighbors needing this type of cleaning. Trust me....when they took out our filters and started cleaning everything...i was amazed at how much dust they got rid of, but also not surprise! haha. Thanks again!
