Air Treatment Company

The technician sent was Trevor. I was called 20 minutes before arrival and within the range given. Trevor was thorough, professional and personable. Air Treatment Company is a great company with outstanding well trained professionals!

We have been customers of Air Treatment Heating & Cooling for well over 30 years. Chris Hunt came to troubleshoot our water heater (16 years old). Replacement made the most sense. Less than 24 hours later we had a new water heater installed by Van and Ju. They were fantastic! Air Treatment is our go to. They take great care of our systems.

I have used Air Treatment for at least 40 years. They are always prompt, professional, explain problems, recommend what's needed. No hard upsell, just what works for your home. Everyone I have ever dealt with has been friendly, courteous and kind. A great hometown (Vienna Virginia) company.

Technician was knowledgeable. He was able to find out the problem and had it fixed in a timely manner.

The technician was polite but unfortunately everything that's where all the positives ended. He tested the execution sequence up to the point where the igniter glowed and stopped short of checking the gas valve and provided the following diagnosis on the service visit invoice - “…I found no voltage being sent to gas valve from furnace control board. The furnace control board has failed and needs to be replaced ($923.78)”

I was already quite familiar with startup sequence of the Furnace from my own troubleshooting research up to that point so wasn't easily convinced about his diagnosis. I had already determined that the inducer motor fired and the igniter came to a full glow but that's where I stopped and called Air Treatment for help. After the technicians departure I proceeded to check for voltage supply to the gas valve during the few seconds when the igniter glowed bright and was surprised to find there was voltage supply to the gas valve during that period before the igniter went out again. I repeated this test a couple of times thereafter. Clearly the problem was with the gas valve and not the board, even though there was an outside chance that the voltage being supplied was not adequate as I only had the tool to check for supply, not to determine the precise level of voltage. Note, the technician had diagnosed there was no voltage supply to the gas valve whatsoever.

I proceeded to get quotes for the gas valve and the control board from the few HVAC servicing providers that did not mind providing a quote without requiring a diagnostic visit. Not surprisingly each of them quoted significantly less for changing the control board ...between $700 and $500. Finally I stumbled upon a provider who offered a free second diagnostic if I could show them a receipt from the first one. Their technician proceeded to test the startup sequence and confirmed a correct voltage supply to the gas valve and then setup to test the pressure/supply to the gas valve and to our surprise this time the Furnace fired and worked as normal. He asked if there had been recent gas utility work done in the street and I vaguely recalled a crew's presence near my home a few days ago.

We conjectured it could be a number of possibilities including introduction of some kind of lag or air pocket or possibly the beginning of intermittent trip ups of the gas valve that was beginning to fail. Granted he was unable to provide a clear diagnosis but the Furnace was inadvertently fixed as a result of his opening up the gas pressure/supply checking access points of the gas valve after establishing that the fault was not with the voltage supply from the Control Board. The Furnace has been working flawlessly since for nearly a week now.

Either way, it was certainly not a problem with the Control Board as the Air Treatment technician had concluded without testing out the entire sequence and checking voltage supply to the gas valve or the gas valve pressure/supply. Glad I got the second opinion, saved me the ridiculous $900+ that Air Treatment was asking to replace a perfectly working Control Board that had nothing to do with the problem.

They actually came 4 hrs early! I was going to do the job myself, but it would have taken me days of crawling around the attic wt bad knees. They crushed it in like 2 hrs and did a perfect job and the price was great! I was very pleasantly surprised, even wt them giving me great service in the past. Appt was easy to set up. A+A+

Have used Air Treatment Company since we moved into the house 6 years ago as the previous owners recommended them. On multiple occasions they have come to our rescue for A/C repairs and just recently our furnace went out. Their techs are great.

We have replaced our A/C and furnace twice and used Air Treatment Company both times. Excellent customer service and everyone is so nice. The Technicians who have come to perform the (twice a year) system check and maintenance have been extremely polite and helpful. I would highly recommend this company!

Dee did a great job, showing up when needed, and taking care of the problem efficiently and professionally. Additionally, since I wasn't home, he phoned me with all the details and recommendations on things I could do to monitor the system better and reduce future problems. Great service!

Their Technician “Dee” is very professional. He takes extra time to explain everything and the best options available. He is very honest which is becoming a rare commodity.
