“Very satisfied!”

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.”

– Hank

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!”

– Sharon L.

We had numerous mechanical difficulties with 2 different heat pumps

“I’m very greatful for the professionalism and commitment you showed to achieve customer satisfaction. You have intervened on our behalf when we had numerous mechanical difficulties with 2 different heat pumps ultimately absorbing the cost of a replacement system of a different brand. This type of commitment to the customer, in my experience, is rarely seen. This dedication to quality service permeates the entire company from receptionists to schedulers to technicians to the owners.”
