  • I'll definitely go back to Air Treatment and ask for Mike M. specifically.

    “I would highly recommend the Air Treatment Company. Mike M. came out to our home to help us balance the cooling in our house. After inspecting our home and cooling system, he made several recommendations as to courses of action. He also showed us how to program our thermostat so that the house was more comfortable. The house is much more evenly cooled now (even in the middle of a DC summer). I'll definitely go back to Air Treatment and ask for Mike M. specifically for service in the future.”

  • I have used Air Treatment for years but I thought the service this time was exceptional.

    “I was very impressed with the recent service provided by Air Treatment. I had the normal seasonal maintenance performed and had a smart thermostat installed. The technician, Mike, was very knowledgeable and helpful in the thermostat purchase and installation process. I have used Air Treatment for years but I thought the service this time was exceptional. I highly recommend this company.”

    Jack T.

  • Absolutely top notch service provider.

    “Excellent installation of our Carrier HVAC systems, both attic unit and basement unit, and excellent after-sales support as well. Very knowledgeable about indoor air quality and the company was able to accommodate unique air quality challenges and other sensitivities in our home and in our family members. We wanted a duct-bypass VOC filter installed besides the HVAC and they did it the job really well. They recommended air scrubber and we went for it to maximize indoor air quality. They also helped us install additional sound-proofing so that the sound from the systems were further minimized (the Carrier systems we went for were already some of the most quiet on the market, but we wanted to make it even more quiet). These people are very professional and gave me the confidence to go with Carrier HVAC systems which I have been very happy about since the installation. I would recommend them to anyone else without a hitch and also use them again for any future installation and service support issues. Absolutely top notch service provider.”

Both of the technicians (De and Mike M) who provided the service on the respective calls were courteous, educated and took time to explain exactly what they did. They also made me aware of beneficial pricing that I was not aware of. This indicates that the company recruits and trains their people well.
