Customer Testimonials


Water Heater Replacement in Mount Vernon, WA 98273

“Brett and Mason were here last June, 2018 to replace our heat pump with a more efficient air conditioning unit. This time it was to replace an aging water heater.
Both times both Brett and Mason were on time, courteous, and communicative, and did what they said they'd do.
Brett is excellent in explaining everything they do, and when he suspects you're not understanding what he's saying he'll approach it from a different point of view until you understand. We would highly recommend Foss to friends and neighbors!”– Paul B.

The house is warming up, the boiler totally repaired, cleaned and functioning. We are happy customers that will certainly refer Foss to friends and neighbors. Thank you.”

Would highly recommend

“Brett and Mason arrived on time and worked without a break until the job was finished (about 9 hours total). They were very courteous, involved us in decisions regarding installation options and kept us informed of job progress. System was installed in a professional manner and job site thoroughly cleaned upon completion. Would highly recommend.”

Very happy with Foss H&C

“Very happy with Foss H&C. Contracted them to do repairs on a house we are preparing to sell. Kendra, Trevor, and Brett were all easy to work with in terms of scheduling, the repair specialist arrived promptly when he said he would (and even called ahead to let me know he was on his way), and their prices were very fair. Would definitely hire again for future HVAC needs!”

– Josette C.

A great experience

“A great experience. Team arrived at scheduled time. Did diagnostics and advised us of problem and cost. We agreed to repairs and the work was immediately completed. We had a few questions about our system and heating/cooling systems in general which were completely and courteously answered. Entire visit was handled within an hour. I am considering Foss for heating system replacement. A very good experience!”
