HVAC reviews in Sterling, Virginia

Jose arrived early, was very knowledgeable, answered all of my questions, and got the job done quickly and efficiently. Highly recommended.

Subash was so professional and easy to work with! He helped me with all our plumbing needs and installed a garage disposal that stopped working when he had almost walked out the door! He was truly a blessing to me today!

My experience with United Air Temp was exceptional. I submitted my claim with my home warranty and they were out the very next day! The tech that came out was very professional and kind! He asked me if he needed to take his shoes off. He was very thorough with addressing the issues that I had with my sink and garbage disposal! He explained everything to me and let me know they would have to return with a replacement part!

David, our technician, came out and identified the capacitor in the HVAC had blown. He replaced the piece but also said that was probably a secondary effect of another issue. He checked the unit and found oil leaking in the bend of the feeder pipe. He repaired the leak and our AC unit is now functioning properly. David was professional, knowledgeable and thorough.
My one complaint is towards the company. We were an "on call" appointment, which means they will get to you that day when they can fit you in. The hours of that can be 8am to midnight. I appreciate the company trying to fit us in, but working such late and long hours is not a great way to keep your talented technicians. Remember if you want to keep your reviews and customer satisfaction high, it all starts with your front line people, your techs. Take care of them, and in return they take care of you.

The Tech, Malachi, was excellent. He thoroughly checked and cleaned our entire HVAC system, inside and outside. He was quiet, polite, and respected our carpet. I have nothing problems recommending him as your next service tech.

We signed up for a service contract. We’ll probably save money over the 12 months and this ensures we’ll get a second cleaning in 6 months -a good thing in the long run.

WORST HVAC EXPERIENCE – They Broke My Working AC and Refused to Come Back

This company is absolutely unacceptable. My AC was working perfectly fine before United Air Temp came out through my home warranty provider (American Home Shield). Their technician barely diagnosed the issue, ordered the wrong part, and said the unit “should work” until the part arrived. Two hours after he left, the entire system failed.

I called their office immediately around 4:30 PM that same day, trying to get the technician back out to fix what had clearly gone wrong. They stalled, said someone would follow up—and then told me to call my warranty company instead. I called again and was promised a supervisor callback. No one ever called.

Today, I called again and tried so hard to get them to understand that this wasn’t a new issue—it was something their technician caused. The system was working before he touched it. It completely stopped working after he left. What do they think happened? It didn’t break on its own. But they still refused to send anyone out and said I have to wait several days for a new part—the wrong part they ordered in the first place.

It’s clear they’re trying to avoid responsibility instead of owning the fact that they made things worse. I saw another review from a week ago where someone said they had to wait a week for a part, too. But in that case, the AC wasn’t working to begin with. In my case, United Air Temp broke it—and now won’t fix it.

This isn’t just poor service. It’s negligence. I’ve filed formal complaints and will be escalating this further with the Better Business Bureau and state consumer protection agencies.

Avoid this company at all costs.

I called United around 7:30 PM Friday night and got in touch with Marcy who was very helpful in setting up an emergency stop for one of their technicians in the area. My AC unit fan had stopped and one of the components fried. With the temperature is in the 90s and 100s— and I have pets— I was eager to find someone to come out to my house as soon as possible. That’s where United Air Temp stepped in. My service tech, Nicholas, arrived and set to work fixing the unit. Nicholas was very kind and clearly had been in this field for a some time. His confidence and experience made comfortable with how this transaction would pan out. He explained everything thoroughly and helped me better understand the unit and what to look out for in the future. I did not feel pressured to purchase additional items or services even though in the end, I did, simply because the customer service that I received in this emergency scenario was fantastic.

As usual Terry analyzed the problem and fixed it! We are up and running and very grateful for his service excellence and quick response! To be honest he has been working on my units for years and would have no one else here as we have a great relationship! Will say James has Ben here as well and provided the same service!

They were the only one who responded to call on Saturday after 6 hrs looking for a plumber and very fast and quick setvup me with a emergency- on the go - appointment and the plumber called and showed up 8:30 on Sunday morning! I'm
Very happy with them

Sebastian S. Was great! Very professional and knowledgeable. Appreciated his great customer service.

Update to review - AC issue after they came out. AC was not turning off when hitting desired temperature and stopped cooling. Called and they came back out next day and I was advised I had a clog and there was an ice buildup…not sure how it goes from system is great to this issue within 24 hours. Fast forward to today and another company comes out and finds I have NO Freon! As well as a leak to boot! Now have to pay for 6 pounds of Freon and wait for the repair. System has been down since last week!!!! So upset this is where we ended up…no clog was found either…next steps will be reaching out the corporate office.

Technician was not able to do diagnostics because the machine was overheating and he wanted the machine to "naturally cool down", told us that the machine needed to be looked at the next day and that the company would give us a call. I called the company and not only did he not make an appointment for us, turns out we were supposed to call, and they don't have any availability for another 36 hours.

Another company already told us we have a leak on the inner coil, took them 1 minute to figure out after plugging a machine to look for leaks.

I wish I could post a video. Had a faucet replaced and they left it way worse than it was before. To close the faucet you have to turn it 3 or 4 times. It is also leaking. I am disappointed that the gentlemen would leave with the job not done. I have had ok experiences in the past but this is by far the worse.

I am a long term customer, 20 years of superior services provided by United Air Temp! Jose called to confirm his arrival time. He explained findings and recommendations.

The technician called to see if he could come early! Showed up when he said. Did a good job. Offered advice and other services without feeling pushy.

Absolutely outstanding service! Very thorough review of a leak we had near our AC unit, and full maintenance was done after as well. Highly recommend. Thank you again for the great service, Mike!

Shawn was an excellent service technician. He took his time to clean the system and explained how to continue the up keep. Awesome, thanks much.

David displayed an awesome mix of professionalism and approachability. He was very patient and detail oriented in addition to doing a an excellent job. He explained everything before starting. Discussed options and gave personalized recommendation. Asked if I had any questions before starting the work. Reviewed everything with me after he was done. And asked again if I had any questions. He was really willing to help all the way. He also offered other services his company provided in case I wanted a step further with upgrades and such.

The best service ever! The technician took his time showing me what went wrong, explaining how everything works and was a very professional!! 10/10 would recommend

He was great, explaining about his work and his recommendations, we even install the condense overflow switch !! Great service ,Mr. Cardenas

For years, I've been very happy with UAT and my favorite technician, Jose. He's very friendly and knowledgeable!

Rudy Junior was excellent and totally different experience than 2 years ago with same firm. He knew the issues and fixed them quickly while explaining what he found and what we could do to pre ent similar issues . Highly recommend asking for Rudy Junior
