5 Star Rating

We are proud of our 5 star rating and continue to strive for providing excellent service!

The guys from Gray's Mechanical did a great job with the installation of a new furnace and air conditioner at my mother's house. They came out to do an estimate the same day I called. They came on time and completed the install of both furnace and air conditioner in a matter of hours. They removed all old parts and cleaned up after themselves. I would recommend them for any residential heating and air conditioning needs.
