Foss Heating & Cooling has been serving Skagit Valley since 1974. We specialize in residential and light commercial service, retrofit, air quality, and water heaters. We are a Trane Comfort Specialist and Mitsubishi Diamond Dealer, which means that we must attend training and offer exceptional support for those brands while servicing all other brands as well. Our focus in on 100% customer satisfaction and taking extra care to educate our clients on the importance of proper equipment sizing, efficiency, safety, air quality, yearly service, and properly sized, sealed, and insulated ductwork.
