CORETEMP Heating and Air was recommended to us by a friend. We called and asked for an estimate on a tankless water system. Richard was very obliging and provided an estimate on a new furnace at the same time at my request. After a very informative discussion with Richard we decided to proceed with both items. The job was completed according to the appointed date. I hardly knew they were in the house. When they finished, I anticipated having to cleanup inside and out. But to my complete surprise there was nothing left to clean up. I would recommend this company very highly.
