My partner and I have an old gas gas furnace that is almost 15 years old. I remember when we bought the gas gas furnace. It was the middle of a cold Winter time season, and my partner and I thought we ran out of fuel. It started to get legitimately cold in the middle of the night and my first thought was that the pilot light went out. Unluckyly, pilot light was not the problem. After carefully checking through the gas furnace, I felt that the concern was an issue with the heat exchanger. This was not an issue that I can fix at home, and I knew that I would have to contact the heating repair supplier. When we woke up in the morning, my partner called the heating supplier to request an appointment time, however luckily, they had an appointment for the same morning. My partner and I had to wait until the morning to see the heating repair guy, however he investigated the concern for many hours before he came to tell us that the heat exchanger could not be fixed. He recommended that we buy a brand new gas gas furnace, since ours was already more than a decade old, but now we have another gas furnace that is just as old and it is starting to have complications. Both of us have had a gas gas furnace for almost several decades and it might be time to option something different. I might choose an electric gas furnace this time, so my partner and I do not have to worry about running out of gas in the middle of the cold Winter time season.
