HVAC reviews in Vienna, Virginia

I contacted several companies before going with this one to replace my broken ac and old furnace because the service technician, Chris Hunt was very friendly and their quote was the most reasonable. Even though we changed our mind at the last minute from replacing just the ac to replacing the entire system, they also accommodated our order change. Then on the day of install, Andres and Ted worked wonders to get it finished in extreme heat. I would recommend this company to anyone looking for a reasonable and trustworthy HVAC company.

They did a fantastic job and they were my significant margin less expensive than the five other bids I got for the same top of the line equipment

Teams showed up on time and completed the work on schedule. They had no problem installing a wifi enabled thermostat instead of the original one in their proposal. We also got a new AC unit (not pictured) - they will come back in the spring to test when the weather is warm enough to see if it can be made colder! The company provided the permit and we scheduled the inspection - work passed with no problem from the City of Fairfax (gas furnace). The inspector also looked at the AC unit but I wasn’t exactly sure why.

Excellent service. I emailed the company in the evening (my A/C stopped working), and they answered first thing in the morning and came to my house at a convenient time for me that day. Lilly expertly diagnosed and fixed the problem quickly, and my A/C was working again. She was very professional, informative, and highly skilled!

I have used Air Treatment for my heating a cooling system for well over a decade and their customer service is top notch. Tgeir pricing is quite fair. The technician always shows up during the designated window. And the technicians are always professional and knowledgeable and are happy to answer questions. I recommend them to my friends who are in need of a new HVAC company.

I had an AC unit and a heat pump installed in the last two years. All the Air Treatment technicians I interacted with were very knowledgeable and helpful.

The technician, Chris, arrived well within the window I was given. He was careful with my house. He was friendly and efficient. And he explained to me what he had done and the state of my system. Very satisfied.
Air Treatment installed my system 10 years ago.

Great Company & Staff! Air treatment has serviced and replaced the HVAC systems in my home for years. The office staff is great at proactively helping me get service scheduled and the technicians are always very knowledgeable, offering suggestions without being pushy or trying to over sell me. Would highly recommend to anyone for annual maintenance or emergency calls

Highly recommend - I’ve had a service contract with them the past few years and they’ve always taken care of me. Had to replace my entire system and they quoted me a great price and did a great job during the install. They really go above and beyond and care about their customers.

Our furnace stopped working. Trevor, the technician who visited our house on the same day we called for help, he was exceptional. He was honest, efficient, and quickly diagnosed the issue. He fixed it, provided great advice on maintenance tips, and made sure everything was in order. Thanks ATC team!

This is a team of very professional, reliable, knowledgeable, and friendly people! We have been using them for over ten years and have had nothing but positive experiences with each person and each service.

I was having an evaporator coil that was freezing up, and I chose Air Treatment because of the excellent customer service I received from a previous install of a new condenser. Lilly was the tech that was assigned to assess the issue, she was very meticulous and very knowledgeable ( which also taught me a few things regarding the science behind HVAC systems and the somewhat complexity of balanced refrigerant) Lilly did an excellent job in making sure my system was operating properly after troubleshooting and correcting the issue. I had another great experience with this company and I highly recommend them A++!

Prompt excellent service. Mike is an absolute expert on the functioning of our commercial HVAC system. We have relied on him for almost a decade. Air Treatment Company has amazing technical support and customer service.

Fantastic service steve was great. These are very trustworthy people. I’m glad that I was recommended to them.

Working with Air Treatment was a great experience. The office staff was polite, professional, and promptly returned my calls and kept me informed about the product wait times and the installer’s ETA on the day of. The sales rep was by far the most knowledgeable of the various companies we got quotes from. The quote and pitch were very low pressure, which was appreciated. Pricing was by far the most straightforward and very competitive, and the recommended products were top of the line and in line with my existing system and expressed goals. The installation went smoothly and professionally. The installers were careful and followed through with protecting the yard as requested. System works perfectly. I couldn’t be more pleased. Do your due diligence and get additional quotes but you will very likely settle on Air Treatment.

I called them at the recommendation of a colleague after my AC stopped working in the middle of a high heat warning. We have pets and wanted to get things fixed ASAP. They came the very next morning and spent about 30 minutes here. They discovered the likely issue, fixed it, and explained how to monitor things to ensure the fix worked. The technician was nice, he arrived on time, and was knowledgeable about our system. I will use Air Treatment Company from now on!

We had a great experience with Air Treatment. They were able to get us an estimate quickly, gave numerous options, and answered all my questions when selecting which system made most sense for our house - all with no pressure or upselling. They got us on the schedule really quickly for the install, and performed the work professionally. The entire process was positive and smooth. Would highly recommend.

I post very infrequently, but Air Treatment did such a great job that I felt it was important to support such exceptional service. They very quickly inspected our furnace when it had a problem, and offered reasonable pricing when it was clear the furnace needed to be replaced (they even price matched when we found another service that quoted us a lower number). They arrived precisely on time for both the inspection and installation—which as you know, is highly unusual these days—and were incredibly professional. To top it off, across the board they were some of the nicest people we have ever met in the service industry. If you ever have to replace your furnace, I would highly recommend Air Treatment Heating and Cooling!

During the early July brutal heat wave, our A/C system completely gave out and required replacement. Our regular provider was so swamped they were unable to dispatch assistance for several days, which would not have been feasible. Although we were not Air Treatment Company customers, they jumped right in and someone come out the next morning. They then got a crew to volunteer to come in on a Saturday and do the required work. Kyle and Taylor were fantastic. We were very pleased with the courtesy and the service provided. Thank you.

Outstanding service is the Air Treatment (AT) hallmark. Our system was installed by another company. However, they did not follow up on problems which arose. We asked AT to check their work and they came up with solutions to the problems. They pointed out that the system was not installed properly. That was at least 5 years ago and they've provided great service twice a year to our system ever since. They are competent, very knowledgeable, friendly and timely. A Great Company.

I couldn't be more pleased with Air Treatment Company. I had them replace my air conditioning system (condenser unit and evaporator coil) last November prior to the change to the new freon requirements. I got quotes from several companies and Justin was by far the most knowledgeable (having previous technician experience) and professional estimator, walking me through my options and explaining everything in detail. While they weren't the least expensive quote I got, they did provide very competitive pricing and no one else offered the labor warranty they offered. Ted and Andres did a great job installing the system. Air Treatment goes above and beyond other companies installing items and performing certain installation techniques that other companies don't take the time to do. When it was time to start using my new system, JP and Kyle did an excellent job making sure the system was performing properly and explained everything I needed to know for proper operation. Air Treatment really goes above and beyond and I couldn't be more happy I went with them. I highly recommend them and I will be using them from now on for my HVAC and hot water heater needs. Thanks Air Treatment!
