Great work, I would highly recommend this company for any project you may have. They were very transparent with pricing. I was glad they were willing to make sure they could repair AC vs trying to sell me a new one. To me this show honesty and will definitely continue business with them!!

I cannot recommend Grays Mechanical enough especially Sergio! I needed the AC filters in the window unit replaced. Sergio was very timely, courteous, and efficient. 5 star service!
Gray's Heating & Cooling's reply
Sergio did service your PTAC (heat/cool) window units and replaced all the reusable filters. Maintenance is key in keeping your units working efficiently. We look forward to providing any HVAC needs you may have in the future.

I had an amazing experience with this company and their employee Sergio. He was very nice and professional and got our heater fixed so quick. He had to leave to get a part to fix it and came back super fast. I would highly recommend this company to family and friends!
