Stewart Heating & Cooling is a Trane Dealer, which means we consider Trane products the best in the market, so that is what we sell. At the same time, we are able to service any major brand of air conditioner you have, and in most cases, use brand-specific parts. It can be pretty miserable indoors when the A/C breaks down on a humid 90º day, or when the unit you have is too small for your total square footage. A properly sized and installed A/C unit should provide 15 to 20 years of summertime comfort. Learn about our maintenance programs by clicking here.
