Customer Testimonials


Ductless Mini-Split Installation in Anacortes, WA 98221

“The Foss team showed up on-time, well-prepared and did a great job of installing our Mitsubishi mini-split system. Mark walked me through all of the options and was prompt in answering any questions during the process. The installers were meticulous making sure that the indoor heads were correctly placed and that any visible components were level, plumb and cleanly installed. The process wrapped up with the system activation and a thorough test in both heating and cooling modes, verifying that the units were within the manufacturer's specifications by performing wet-bulb/dry-bulb tests and lots of calculations. The numbers were right on the mark. It was easy to see that the guys knew what they were doing and not just "going through the motions". The subsequent follow-up to make sure that we are satisfied with the system has been great as well. There's no question that we will continue to use Foss for our HVAC needs.”– Chris M.

Gas Furnace Maintenance in Mount Vernon, WA 92873

“Upon recently purchasing our home in late 2018, we had a few issues in the winter that prompted us to coordinate some repairs and subsequent ongoing maintenance. The furnace unit in the home had a maintenance sticker from Foss in the past, so we figured we would start there – and we are glad we did! Our experience with Andrew and the customer support from Foss has been fantastic! They corrected some existing issues for free and got us on a maintenance plan that is well worth the value it brings to our family and home. We highly recommend Foss to everyone in the area, and will continue to utilize their services for years to come!”
