"Highly recommend Mike Gross & Son's Heating & Cooling. Called requesting AC service, was here, did repair and was done by mid morning on the day that I called. We have called the original installer of our heating/cooling system. He doesn't pick up. He doesn't respond to messages left... MIKE GROSS is our NEW GUY."
