Keystone Htg & AC Co, Inc

Super Service! Jack did a great job of helping us out in an extremely COLD pinch! New furnace and AC have been ordered.

Paul, a.k.a. "Winston" was very professional, a great communicator, and an excellent technician. I won't hesitate to use Keystone Heating again.

Put our air conditioning in 26 years ago. Had no problems. Just put in new unit last week. Excellent professional service. Very tidy.

Jeremy informed us of the maintenance work accomplished for the heating season and reattached a disconnected W2 wire of which we were unaware. Appreciate the very thorough inspection preventing future problems..

Adam checked out my ac unit and was very friendly, knowledgeable professional and efficient.

I had an excelllent experience all the way around. I would definitely use them again. I'd like to especially compliment the install team for doing a great job.
