Found out my furnace was not working while I wasnt in town today. I called more than 12 companies, including the company that regularly serviced my heating/ac system and no one was available. Clark returned my call and was at my house within 15 minutes. He also fixed the problem within 15 minutes and for a reasonable price! Highly recommend this company!

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.
