Reviews
What customers say
- Rated 5 out of 5
Install crew was in and out in one day and left the basement cleaner than they found it.
- Rated 5 out of 5
Furnace died at 9pm on a Sunday. Ridgeline had someone here in an hour and the heat back on before midnight. Price was exactly what they quoted.
- Rated 5 out of 5
Got three quotes for a new AC. Ridgeline was not the cheapest, but they were the only ones who measured the house. The new unit is so quiet.
