About Us

Tech in Front of FOSS van.

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 is on 100 percent customer satisfaction and taking extra care to educate our clients on the importance of proper equipment sizing, efficiency, safety, indoor air quality, yearly service, and properly sized, sealed, and insulated air ducts.

We have 17 full-time employees and continue to grow mainly through community involvement and referrals from satisfied customers. All of our journeyman field employees carry their Washington State 06 electrical cards, and all of our technicians are North American Technician Excellence (NATE) certified. Foss invests in over 60 paid hours of training a year for each employee. We have an active apprentice program that trains our new technicians and installers internally.
