Amazing service from start to finish. The best customer service I have ever experienced. Punctual. Professional. Proficient. My story: I had 6 giant AC units in wall and in windows and they were loud, unattractive and ineffective. Well, the team came to my rescue big time. Everything was explained by Chris, then Kyle and Will showed up early every day to tackle this 3 level cooling project. Nicest guys you’ll ever meet and they go above and beyond to help make your experience easy. They even pulled out the giant in wall unit to make room for the ductless cooling system which they installed. Love love love these guys. Now my house is beyond cool and the units are totally silent! Thank youAynen

We recently had some warranty covered repairs done in our hvac system. All the team members we met with were professional, knowledgeable, and extremely helpful.

Very happy with my new Carrier HVAC system! AJ and his team were nice and efficient! Matt explained the system to me and they set up the e new thermostats and made sure I knew how to use them before they left. I will get my downstairs unit from USS as well! Overall, I am extremely happy with the entire process and the speed at which I got the install done. Thanks again!!

Fantastic company. My elderly parents heat went out during one of the coldest weeks. United Service Specialists fit them in their schedule and made sure my parents were taken care of. They are amazing and the employees worked so diligently to get it done quickly.

The professional service men Carlos and Dennis for my AC/heating unit were exceptional, demonstrating a high level of expertise and efficiency. Carlos probably identified and resolved the issue. I highly recommend their services for anyone in need of a reliable and skilled heating maintenance.

We love the team at United Service Specialists! We’ve been working with Carlos on our HVAC system after having multiple other service calls from other companies. Carlos was knowledgeable, kind, and helped us to diagnose a new to us AC unit. He’s also serviced our boiler system as well to make both run like new! Carlton has also been helpful at our routine service calls. We’ve had plumbers come out as well, Justin & Chris most recently to help us with a leaky kitchen faucet which turned out to be a whole home water pressure issue. They quickly diagnosed the issue and found the most cost effective solution for us. We’ve also had Marvin come out to help us with a bathroom faucet. Thank you United for helping us with our first home!

Upon arrival, Technician Manual Hernandez went to work on the leaking furnace valve and replaced the backflow preventer and expansion tank. After the work was done, he explained in easy to follow terms what was involved and what to expect from the system which is aging. He carefully answered my questions. The sounds of humming and whistles from both men gave me comfort that he and Dennis enjoy their work! They were considerate and easy communicators. This is my new go to company for heat service.

What a fantastic experience! The response was very quick to my need. Matt (the technician) was terrific. He even sent a text identifying himself prior to his arrival. He took time to explain everything as he diagnosed the problem. He was on time and extremely friendly. Customer service and satisfaction is clearly is top of mind for United Service Specialists. I would highly recommend them!

(Part 2, continued from earlier post)Most impressive though was that if they did run into a snag, they found a solution and worked with someone on their team who could help; if they needed support, they asked for it; and the company provided it. Early on, I heard from Bob the owner who called me at home to tell me he personally was on the job and committed to finding a solution. Clearly he has set the right tone for this company. But I was most impressed with the folks he had on the ground. Matt who was a senior tech on the heating side of the business was very knowledgeable and could not have been more responsive. When he realized we might be delayed in getting heat, he sent someone over during the weekend with space heaters for us to use until they could get us a proper unit installed. While situations like these are inevitable as part of home ownership, they are still unfortunate and certainly an inconvenience for all when they happen. Lets be honest - no one ever wants to be without heat in the winter or AC in the summer or hot water at any time. But its sure nice to know when the gremlins strike you have a team you can count on to work with you and who will step up and see a project through. They sure earned my business. Thanks, USS!

Willy came over to look at our AC, which was not working. It took him a bit to go through all of the possible options, and he eventually called a co-worker to help identify the issue (rather than waste our time), and together they determined that the issue was a faulty condensation pump, once they identified that, they notified me of the price to replace and install the part, did so after I approved it, and waited an extra 10 minutes to confirm that everything worked properly. All in all the main technician (who is younger) did a good job and the more veteran technician did a great job helping out and helping his co-worker. Good communication, prompt, effective. A bit more expensive than I hoped for, but I really am grateful for their good work.

I remember from quite a while ago being so impressed with Carlos Ramirez, that I made a note to request him on the next service call. That may have been decades ago. The very next service call, I think he was not available...and usually we dont plan for emergencies well. My wife got him started on the repair. He had said that he had serviced us before, but, we have all aged. I did not recognize him....and my apologies. I remembered the name when I went through the emails post job completion. Ill be requesting him again next time if things are so urgent. Miss the cheap Honeywell circular thermostats of yore. Are they illegal now??? Never should have thrown away the old one we had. I am sure I could get my hands on a few working used ones. One can buy a laptop for the price of the current fancy thermostat. That is my only complaint.

Hard to say enough thanks for anyone who shows up at your door on a Saturday morning after being summoned two hours earlier. Will took amazing care of us, and was hugely professional — and obviously knowledgeable and competent. He solved our short-term emergency and made a plan for a durable fix in the near future. Three cheers.

United Service Specialists repaired my HVAC unit. I called on Wednesday and the tech came out Thursday morning. They had to order a part but navigated the order and warranty so that my unit was repaired on Monday morning. Customer service was outstanding. Tech explained everything that he did. And I appreciated the texts letting me know when to expect the tech within the 4 hour service window. Highly recommend.

We recently had a new furnace and AC unit installed in a DC townhouse by United Service Specialists. It was not an easy job with the limited space available, but the team at United Service Specialists listened to our needs and helped us to pick the right equipment. The works was done quickly and efficiently, and everyone who came to our house took very good care of our home. We are very happy with our new equipment and the work completed by the United Service Specialist team. All members, including the staff who help to coordinate the schedule, are very nice and extremely helpful. We highly recommend the team at United Service Specialists.

Review 22 (2021-11-14 - Rating: 5)
Jay was great to find us in the system from previous use of their services- she was professional and friendly. They went above and beyond other businesses by sending a text when the technician was on his way. We didn’t realize they had our street misspelled but reached out quickly to get the address clarified. Matt, the technician, did a great job of offering a clear explanation to my husband of the situation, what he did, and whether or not it was reasonable to make repairs to avoid the same problem in the future.Usually, I’ll give 4 stars for really good service. A business has to do something that other businesses don’t do in order to get 5 stars from me. United Services Specialists did that by sending the text with the ETA and by the clear, unsolicited, honest explanation of options to avoid the same problem in the future. They even noted that the option we thought best wouldn’t likely be worth the cost.I can’t recommend them highly enough!

Contracted with USS to add a second HVAC system in my attic. Everyone I dealt with was very professional and the installation was completed quickly without any issues. Also used them for a service call at a rental condo. The issue was resolved quickly and inexpensively. Its great to have an HVAC service that you can trust! I definitely recommend them.

I have used USS for years (both for routine maintenance and emergencies) and I’ve always been impressed with their professionalism and the competence of their technicians. Angela (who handles scheduling) is awesome to work with: kind, smart, efficient with great customer service skills. Chris has serviced my AC unit a couple of times and he is fantastic. Incredibly knowledgeable of HVAC systems, very friendly, and works extremely efficiently. I would recommend Chris and the USS team to anyone.

I had a hole in a water pipe in the crawl space of my house that was spraying water everywhere. United Service Specialists sent Marvin to assess the problem and fix it. Marvin was wonderful. He actually came at least an hour before the time I was told and had it fixed in less than 30 minutes. He was professional and extremely knowledgeable. They are my go-to company for all of my plumbing and HVAC needs.

I reside in Boyds, MD and am very pleased that I found United Service Specialists Heating, Air Conditioning & Plumbing. They were honest, professional and concise in addressing the problem with my AC unit.Carlos and Kyle were my technicians, I received a text with their photos, a bit about themselves and a live tracker on where they were on route to my house. No more being a hostage in your own house for a 4 hour window.They explained the remedy to the issue and are following up.I highly recommend United Service Specialists Heating, Air Conditioning & Plumbing.

We had to use them a couple of times for our apartment building and they have been absolutely fantastic every time. From the moment you call to the moment they get the service done, they make sure that you understand every single aspect of their work and that all of your questions are answered. They are extremely quick to reply as well. They confirm your appointment via email, and when the technician is on the way, you are able to see where they actually are so that you don’t have to waste time wating for them to come. Speaking of the technicians, Carlos is a pleasure to work with, he throughly follows apartments regulations (i.e. 6 feet apart, sanatizing hands) and he makes sure that you understand what is wrong with the unit, what can be done to prevent the issue from happening again and what he will do to fix it. United Services has been of great help and business to work with and I strongly recommend it.

Amidst the COVID-19 chaos, our air-conditioning failed late in the afternoon. To my surprise, I was able to schedule an early appointment for the following day. The representative was very punctual and very professional. Within minutes the system was repaired (blown fuse) and good to go. I was even able to sign up for a routine maintenance agreement, dropping the labor cost of the air-conditioning repair. Fantastic service!

Felix Salgado arrived at our home on time with a willingness to listen as we explained our plumbing issues and need to have a new kitchen faucet and garbage disposal installed. Because a leak had been identified by our neighbor, we initially thought that pipes would have to be replaced but Felixs professional experience guided him to immediately assess what needed instead to be repaired to ensure proper installation of our new appliances. Felix was thorough, astute, and efficient. We appreciate his taking time to explain what needed to be corrected and why. And taking time before he left to ensure that we were completely satisfied. I highly recommend Felix. He demonstrated that he is indeed a master plumber.

I contacted this company seemingly at the same time everyone else did--the first REAL hot week of the summer this year. This meant that their employees were probably booked from dawn til dusk. Despite their overloaded schedule, they made both visits very easy. Carlos was professional and polite, and gave me some advice outside of the service requested that was very helpful. I must say, they were considerably past their 12pm-4pm arrival window for both appointments, but I cant dock a star based on that, because their office was extremely communicative, even past their normal business hours. I would not hesitate to recommend this company to anyone; thank you all so very much for your hard work.

Just had my HVAC replaced including the AC coil and heat pump. Could not be happier with the service and the quality of work. Technicians were on time, respectful of the property, worked cleanly and efficiently. Your HVAC system is basically only as good as the installers and they took every step to make sure it was done correctly. Even corrected a venting error caused by a previous plumbers installation of our tankless water heater. Love the honesty & size of USS. When you call you know exactly who you will end up talking with. Great communication via text & phonecalls. So lucky to have found this company. They recently saved us literally thousands on a sewer main repair bc they were so honest which is why we trusted them with our hvac install. I’ve dealt with at least 8 plumbing and hvac contractors in the last month & most were big names in the DC area. They were all dishonest & pressured us with a ton of sales tactics and ALL suggested work we didn’t need! We got none of that from USS. Absolutely love this company. My installer (Matt D) led a friendly and professional crew today. We had a complete HVAV tear out and install done between 8am and 2pm. WIll definitely be sticking with them for maintenance as well.

My HVAC evaporator coil leaked and was still under warranty. Technician performed a leak test and found leaks on the bends of the indoor evaporator coil. I had refrigerant added earlier, but it stayed cool for only over a month before it stopped producing cool air. The office provided a price quote on the repair estimate and arranged to get the replacement part from Trane. They received the part after I accepted the repair order along with a 50% deposit. They set up an appointment to have the same technician to install the new coil. Technician arrived at the time of the appointment and completed the replacement installation in a little over an hour and added refrigerant back to the system. System was checked for proper operation and job was completed. Company was very prompt in responding to questions and technician did a very efficient and competent job.Note: This review got posted on the company address listing with a Gaithersburg location. My service came from the College Park, MD location.

No complaints here! Billing used to be much slower and our bsuiness was not receiving invoices. Due to a great new system and/or billing practices, invoicing and quotes are handled within MINUTES!!!! Customer Service Staff top notch, and our repair tech, Carlos Ramirez, is even BETTER!

United Service Specialists sent out two experienced technicians today, the latter of whom quickly found (and fixed) a problem with my rooftop AC. My AC is hard to get to (requires 2 story ladder), but USS brings that along, and they do the servicing up there very professionally, despite the access hassle. All the USS team members who have done work here (including Matt and Carlos today) have been pleasant, professional and competent.

After receiving bids for air conditioning splits from four companies, we accepted the bid for a Mitsubishi system from United Service Specialists because of the thoughtfulness and efficiency of its representative, Chris Anderson. The technicians who began installing the system, Dennis Castro, Kyle Williams, and Will Hawkins, were polite and obviously quite knowledgeable and did their work in a quiet, efficient manner. When the outdoor units could not be delivered due to supply chain bottlenecks, the whole enterprise could have gone quickly south, but Manager Brendan Warshauer and Scheduling Manager Tien Cao stayed on the case, giving us updates as needed. Eventually, when it became clear that no Mitsubishi units could be obtained in the near future, the team found us a comparable Daikin system. The techs came back and took down the old indoor Mitsubishi units and installed the new Daikin system, inside and out. The finishing work was well done, and we are now enjoying cool, quiet air. I must note that the USS bid was not the lowest, but from the beginning, I felt that the teams professionalism and attention to customer service would pay off. It did.

After dealing with many different HVAC companies, I have never had a better experience than with United Service Specialists. Absolutely incredible service and care. I called them at night after our HVAC broke and they were there the next morning. My husband and I both felt like we were treated like family and that is not something you find in today’s world. Matt spent time with my husband and took his time being thorough checking everything and immediately had Carlos come that same afternoon to take care of Some parts we needed. USS sends out texts to let their customers know when the technician will arrive as well as a description of who the tech will be. The customer service they provide is exceptional. Brendan, the vice president of USS, is there for you no matter what and they make you feel so valued. Plus, they are very honest. USS are also air quality experts in creating the cleanest air, looking out for our health in our homes. I can’t recommend United Service Specialists enough.

Had originally scheduled a spring maintenance look-see on my SpacePak AC system but the day before my appointment my AC system went kaput. Great timing and super-responsive team of Kyle & Will who diagnosed the issue stat: Squirrels had nested in my attic crawlspace and chewed through several wires, drain tubes -- and even flipped the off/on switch to off (!) They returned the next am and replaced the wires, tubing, drain pan, added safety overflow protection, and made it squirrel-proof. Kyle & Will went above & beyond and thats putting it mildly! Highly recommend. Theyve been my go-to HVAC team for 25 years dating back to AB Chelini and the amazing Alexander who was the OG HVAC guru.

Patrick and Nelson did a great job installing the new water heater.However, the preliminary measurements werent perform properly, so they brought the unit of the wrong size initially (it didnt go through our utility room door).

Justin, Chris, and Willie are the absolute best! As a new homeowner, I wasn’t sure about hardly anything but Justin helped me out a ton. Saved me a ton of heartache in the future by giving me tips for preventative maintenance and making even the smallest adjustments for my satisfaction. I’ve used them to service my radiators, put in new toilets, and change my water heater. I keep adding services because I trust these guys so much. Super nice and friendly. Very knowledgeable and they definitely go above and beyond for you!

We just replaced our old and failing HVAC system with a hybrid heat pump system. We shopped around for estimates and based on the quality of our interactions with and information from the company we feel we got the best product and price from USS. Our salesman Matt was quick to respond when we called with questions and concerns, and the installers were prompt, professional, and did the job quickly and with apparent care. Were very pleased with our new system and I would easily recommend USS if you need any of their services.

Review 114 (2021-07-15 - Rating: 5)
I needed some work done on my home from two different technicians for two different issues within the same week. Marvin is a great guy and knows his stuff. He had my old sump pump that was deep in a dirty old pump well all cleaned up with a new pump in no time. And Carlos was also a great guy! He diagnosed and addressed the issue with the AC unit leaking water onto the basement floor. Both gentlemen were timely and very professional. They never talked down to me or anyone in my family and were always happy to show us what they were doing and why they were doing it.

Christmas Eve during a Bomb Cyclone is the worst time for a heating system to go down... and after contacting over 15 HVAC companies who understandably were swamped, or closed, United Service Specialists came through big time! From the first contact by phone to the Tech is on the way tracker, diagnosis of a frozen condensate line and fair pricing all within a few hours! My HVAC and plumbing company from now on!

Review 116 (2021-06-17 - Rating: 5)
Our inside heat exchanger needed cleaning. They were the 3rd company that looked at it. The first 2 claimed we needed a new system. I didnt believe them. It was 4 years away from the beginning of when it might go. I have had 2 systems that had to be replaced and this wasnt close to how the other 2 behaved. It was cooling very well but the air flow wasnt as good as it needed to be if it was real hot. I thought it needed cleaning. Then if it couldnt keep up I would consider a new one.Ours only couldnt keep up when the weather was in the 90s it was fine in the high 80s. The tech was honest and said it needs cleaning and after it was done it was fine. I will likely report the first company who changed us $150 to lie to us. They were top rated too.

They responded quickly. Problem with furnace diagnosed and repair was completed in less than 30 minutes. American Home Shield contractor wanted me to replace furnace for $2900. Their contractor also misdiagnosed the problem. United Services repair cost less than $300. I am requesting a refund from AHS and will close my account with them.

Review 147 (2025-01-08 - Rating: 5)
Our furnace needed a new motor and they were waiting on the part to arrive from PA so they could complete the repair. With the recent snowstorm and frigid weather we expected a delay getting the part. Luckily we had space heaters and a gas fireplace help keep the main level of our home slightly warm while we navigated what we needed to do from day to day. Fortunately the furnace in the attic works fine and kept the upper level where the bedrooms are pleasantly warm so we could sleep:) We survived and I was never so happy to see a serviceman arrive at my door! Mike was extremely pleasant and knowledgeable and performed all of the necessary tasks to get the unit working properly. I’m so grateful to this company as we have been working with them for many years. We have a plumbing issue which is being assessed by their plumbing department on Friday. When it rains it pours as they say!
