OUR HISTORY

We want the quality of your new heating and cooling system to give you comfort and satisfaction. 

Thermal Associates is a heating and air conditioning company servicing the Glens Falls area including Warren, Washington and Saratoga counties.  We have been in business for over 40 years and it is our award winning service that has kept us here. Marty and Marj DeVit, founded Thermal Associates in 1982 leading the industry in green energy HVAC systems. Adam DeVit followed his father’s footsteps into the industry in 2004. Marty & Marj officially retired in 2023, passing the torch to Adam who plans to continue leading the industry using improved green HVAC technology.


Thermal Associates was a pioneer in air source heat pump technology during the fuel shortages of the 1970's and 1980's. As a logical progression Thermal Associates lead the way to earth coupled heat pumps, now called geothermal heat pumps or ground source heat pumps. Marty patented a heat pump in 1990 and was very active in the production of heat pumps in the Northeast under Cantherm and Amtherm.



Over the years, geothermal technology has progressively grown into highly efficient systems as produced by WaterFurnace Renewable Energy, Inc. As a company that has been working with heat pump technology for over 30 years, Adam DeVit, his family and Thermal Associates are industry leaders in the Capital District. Moving into our next generation, Thermal Associates is ready to lead the way with new HVAC technologies for our customers.
