Critical: Professionalism, Quality
Friend had a problem with his evaporator dumping water all over his furnace and floor. This company installed the completely wrong sized evaporator coil for the furnace and covered the imperfections with foil tape, also ran bad drain lines. Do not recommend.

I had a very noisy episode with my furnace and it really scared me. I called Gilray and when they showed up, we found that a mouse had committed suicide in our furnace, which is what caused the noise. He completely cleaned out the interior of the furnace and checked everything for us! I will now have my furnace cleaned yearly, he found it wasn't the first visitor from above! Great service, great prices, now a loyal customer.

Our gas furnace has been leaking water since early fall when we first turned it on for the season. Multiple attempts to schedule with a different provider, recommended by a friend, were unsuccessful. I left my name and information several times, and never received call-back. Low on cash, I decided to use up whatever firewood, heating the house by fireplace for the season instead. Running out of wood early, I again attempted to contact Gilray's competition, as the amount of water leaking from the furnace had significantly increased. Kindly, a representative from Wills called me back stating they

Suppose to come on a Monday or Tuesday to service our furnace. Never came and never returned calls. This was when it was really cold. What a way to run a business!! And what a way to leave people who need help hanging. Terrible!!!

They did an excellent job on a few projects I needed done professionally before I could close on our house. I was very happy with their communication, the work, and the final price. I highly recommend...
