Three towns on both sides of the Mohawk
The Mohawk River runs through this part of our service area. It forms the north and east town lines of Niskayuna, where Erie Canal Lock 7 sits. Glenville is on the north side, with Schenectady County Airport north-northeast of Scotia, and Rotterdam is to the west, home of the Mabee Farm Historic Site.
We work each of these towns the same way: test the system, explain what we found in plain terms and give you the price before anything gets touched.

Highly recommended- I had a complex project and Stable Air was the only team who provided a solution, and was reasonably priced. I had an oil furnace and some duct work running through my 200 year old farm house, and no a/c. I wanted to convert to solar power and have mini splits to have clean …
In 2023, after installing solar panels, we decided to ditch our gas furnace and transition to heat pumps for heating and cooling to finish our home’s transition to all-electric. Tony was very knowledgeable and did a fantastic job, including making sure we had heat pumps that could handle the winter …
Back in 2022, Stable Air completed a full overhaul of our HVAC system, removing our old, extremely inefficient fuel oil furnace and base board heating and replacing it with a brand-new ducted heat pump system with all-new ductwork. They also upgrade our homes insulation by sealing and insulating …
We can't recommend Stable Air Heating & Cooling enough! As first-time homebuyers, we unfortunately learned the hard way that we had been taken advantage of when purchasing our home. The house had vents throughout for central AC, and there was clear evidence that a unit had previously been …
Anthony installed central AC and a new furnace in our house. The AC has worked great, even on the hottest days. We have not used the heat much yet, but we are very excited for the built in whole house humidifier, that he installed as part of the system. In the winter, we'll have hot humid air …
Stable Air exceeded my expectations in nearly every way. The owner was extremely well communicative not only while price shopping, but once we had confirmed and begun the work. The work itself was professional and top of the line in quality and performance. They gave us an upgraded unit for the …
I was having problems with my furnace and had read some reviews on Nextdoor about Stable Air. I decided to give them a call and make an appointment. The owner of the company came over and examined the furnace. He told me he could clean it and presented an alternate idea…a new system. He gave me a …
I have been using Stable Air Heating & Cooling since 2022. I originally contacted them to replace my aging furnace. Not only did they give me a great price, the work they did made a world of difference. I had ticking noises in the ductwork prior, the owner took time to redo some of the ductwork …
It is very important to me being comfortable in my home. Stable Air Heating and cooling has been helping me with this for years. The owner is knowledgeable and fair. He went out of his way many times to diagnose problems and get my furnace up and running so i wouldn't be without heat. One time he …
