We needed our furnace checked out for winter. Dennis came, he was very good about putting covers on his shoes every time he came in and out of the house. We had previous trouble with the furnace before, it kept coming on for a short period of time then turning off. It took him a while to find the problem, but he kept checking and tried using different instruments. He found the problem, fixed it, and now it works nicely. We are pleased with the job he did.
