Customer Reviews

Rose Ehrgott

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

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.

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
