About Us
Built for North Decatur's Established Homes
Westcrest Heating & Cooling is based at 2920 N Main St in Decatur, on the city's north side, where much of the housing stock has been standing for decades and the heating and cooling equipment in it often has too.
Owner Reid Thornton built the business around honest diagnosis of aging systems and real Midwest four-season reliability: a furnace you can count on in January and an AC that keeps up in July.
