Furnace was constantly shutting down, making an odd sound the entire time. The team from Hy-Pro was called at 8am, arrived by 12 noon and had the problem fixed by 1pm. I was charged only the diagnostic fee which was already initially agreed to on the phone. I was kept up to date multiple times along the way from the admin staff on when they could be expected to arrive. Highly recommend this company and will be using them for any upcoming HVAC issues.
