Just wanted to say how impressed and pleased I was with the furnace service I received from the serviceman with Gregg's Plumbing & Heating. We had 2 furnaces to be serviced and the serviceman worked on our furnaces for approx. 3.5 hrs. which included replacing a damaged flame sensor (after he explained this problem to me, quoted me a price, and asked if I would like this done). I believe that this part needed replacing because our furnace had quit working last winter and we had another company come out and "clean it off" but stated it didn't really need replacing. Thanks again for the great service.
