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 percent 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.

Air Conditioner Maintenance in Anacortes, WA 98221

“Arrival time was well communicated and updated. Brett was very professional and friendly. The results were well documented and explained. No pressure to upgrade or purchase additional services. An excellent example of how a maintenance visit should go.” – Dennis S.

Boiler Repair in Sedro Woolley, WA 98284

“I called two other heating companies before Foss, they wouldn’t even give me a call back.

Foss sent a guy out the same day , Jarrod did an excellent job in diagnosis and repair and cleanup. Foss is my new go to heating company!”

– William L.

Heat Pump Maintenance in Anacortes, WA 98221

“Michael came out to do the first maintenance on a duel fuel HVAC system that FOSS installed last year. He was very professional, knowledgable and personable, and even stayed late on a Friday afternoon to install an air scrubber that was not part of the original plan. I had been thinking about one recently, and he provided a lot of information, and gave me time to do my research online while he did his maintenance. Since he had an ozone-free model in the truck, he just installed it then and there. And cheerfully too, esp at 5 PM on a Friday. Very excellent service”

– Barb T.
