Our furnace had been working fine for 10 years with no issues. We had another company come out to service it and shortly after our furnace stopped working. That company came back and said nothing was wrong and our furnace was still not working. Called Gerard and Action Heating & Air Conditioning LLC and they came out and got our furnace working again. Very friendly and hard working. Did not just try to sell me another furnace. I would recommend them to anyone!
