"We had a fan noise from our furnace and knew we needed service for the first time in 20 years. Having seen your trucks often in our neighborhood, we guessed you were good. We confirmed it with comparison shopping on the Internet (ratings). We are so glad we decided to work with you, as our furnace totally failed in advance of our new-furnace install date. Who knew! We called on Sunday and you completed a temporary installation Monday. Warm regards!"
