Heat Pump Maintenance in Sedro Woolley, WA 98284

November 16, 2021

“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"”

“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!”
