Rose Ehrgott on Foss Heating & Cooling

We replaced our 30 year old gas furnace and the whole team from sales through installation and system start up were fantastic. Competitive price, and exceptional service. Great communication and professionalism. They explained the new system to us and made sure we were comfortable with the operation of it.

Graham Armstrong on Foss Heating & Cooling

I used Foss to get a second opinion on our aged, broken furnace, and I am very glad that I did. Brett was very professional and he was able to diagnose the issue very quickly. Total repair cost was less than what another company estimated just to finish the diagnosis. I felt he was very considerate with his explanations and suggestions.

Jim Kendall on Foss Heating & Cooling

Foss performed an overhaul of our HVAC system, and we couldn’t be happier. The quality was top notch, service afterwards was immediate and efficient, and everyone was professional. Their pricing was fair and transparent, you get what you pay for in this sector. They’re the only outfit we’ll choose in the future, thanks guys

Andre at Foss Came to our rescue with very little notice during a cold week in February. I was at work at the time and my wife was not confident to deal with the situation, but he did a great job of communicating with her and making her feel at ease. He kept in constant contact with me while I was at work. He was very transparent about the repairs to our very old gas heater and gave me several options to work with. He got our heat back on in time for my wife to get to her job. She later told me that if we ever need more repairs we have to get Andre again.

Oh. And they liked my dogs!!
