My brother messaged me a few days ago, because he didn’t think the gas furnace was heating the house. I am not a full-time gas furnace maintenance contractor, although I am currently going to college to become certified. I told our brother that I could only lend a helping hand and I would not be able to repair the headache that I was having; The best I could do was deliver him a system of what could be wrong. I went to the house last night and I could tell that the gas furnace wasn’t entirely working right. The moment I walked through the door, I could tell that it wasn’t quite as hot as it should be. The temperature on the control unit was reading 72 degrees, however it was definitely not that hot inside of the house. I told our brother to get the thermometer from the front porch and put it in the front of the living room. I had a sneaky suspicion that the problem wasn’t the gas furnace, however certainly the control unit! We sat around the supper table and had spaghetti, meatballs, garlic bread, and a healthy helping of cheesecake. I wanted to deliver the control unit time to calibrate before I checked the temperature, and just as I imagined, the temperature on both control units did not match. I told our brother that I was almost certain that he needed a new control unit, however he is going to get one sometime this month and see if that fixes the problem. If it does, after that the two of us just saved our brother a ton of cash.
