Customer Reviews
What People Are Saying
 

“Save money, time and aggravation. Just call these guys. I have two other heating companies charge me and couldn't solve the problem. Grey Furnace figured it out in 10 minutes with a simple adjustment.”
— Tom S.  |  Angi
“Worked past five PM to complete installation and start up. Had an issue with condensate drain line leaking in the attic. Gray furnace sent out an excellent technician to correct the problem immediately after it was reported. Very satisfied.”
— Eric M.  |  Angi
“Gray Furnace Service technician Dave arrived at the scheduled time of 10:00 am, quickly accessed what he had to do and went right to work. He was prepared bringing all the materials and tooling needed. He recovered the unit's Freon, then proceeded to disconnect electrical power and undo refrigeration lines. Once he verified new location of condenser unit, he placed it there and went about reconnecting copper lines and electrical. The air conditioning unit was then recharged and run to ensure proper operation. Dave then proceeded to access the second a/c unit. He made a quick repair to a copper line that had a small hole then recharged the system. Upon completion of unit recharge, system was started and checked for proper operation. Dave displayed the skill of a true professional. The quality of his work was very good and he was very courteous. I will use the service of Gray Furnace again without question.”
— Luis M.  |  Angi
“Responded quickly, courteous and knowledgeable. Disconnected the booster fans. ramped up the furnace fan to high, and allowed me to "live with it" for a few days to see if the change provided sufficient heating to the upstairs. It is still the first week and I am evaluating the result, and I appreciate Don's handling of my problem in this manner. I am hopeful that the booster fans are not necessary any longer (they sound like an airplane taking of and landing when they go on and off). Will definitely also call on him to do the A/C tune up in a couple of months.”
