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.

“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!”

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”

Heat Pump Maintenance in Sedro Woolley, WA 98284

“The first annual check up on my heat pump. Michael MacLachian was the service technician that arrived to do the work. Very involved and thorough going through the equipment inside and out, replacing the filter, even checking the outside fan and cage to make sure all was clean and in good working order. I was very pleased with Michael, how efficiently and professionally he did his job. Just like the crew that did the installation a year ago. All hard workers, no cutting corners, quality workmanship, equipment and product. Would always recommend Foss, he hires the best! That is why when the inspector came to check the installation last fall, he said "he never worries about Foss workers not doing top quality work"”

Air Conditioner Maintenance in Mount Vernon, WA 98273

“Brett called before arriving and came to our home on time. He was personable, professional, and very informative in answering questions that we had. He performed the Spring maintenance of our home system as part of our service agreement. He shared about several issues that we know we have with our system. He replaced the thermostat with a model that will work great for our needs without selling us the most expensive one. The explanations and recommendations made for resolving our long-term heating and cooling needs were excellent and we believe them to be accurate. Brett is an excellent Foss Heating & Cooling representative and we are very pleased with the service we received!”
