Not happy with my furnace
My home is heated by a forced air furnace that links to a system of air ducts.
The ducts are mostly concealed inside of walls and ceilings and connect to vents located in the rooms of the home.
I am not overly impressed with this type of heating system. While it is the most popular choice and quite energy efficient, there are some drawbacks. The heated air passes through the ductwork multiple times a day. If there’s any dust, pollent, mold growth or bacteria concealed within these pipes, it can become airborne and spread throughout the house. If there are any tiny holes or cracks at the seams of the ducts, the heated air leaks out and is wasted. A duct system that is operating at peak efficiency typically allows four percent of conditioned air to escape. The air that reaches the vents is blown into the various rooms. This influx of heated air creates temperature fluctuations within the space. Plus, hot air naturally rises, which means that our heated air floats straight up to the ceiling. It only drops back down once it’s cooled. With the highest temperature in the room being up near the ceiling, I need to raise the thermostat setting to keep my family comfortable. The furnace is very susceptible to issues from dust accumulation. I need to make sure I replace the air filter every month and schedule professional maintenance every fall. If I allow the dust and other debris to build up, it restricts airflow and forces the heater to work much harder. There’s the potential of the furnace overheating and causing a crack in the heat exchanger. Since the heat exchanger keeps carbon monoxide out of the living space, it’s an important part. It also costs more to replace than a whole new furnace.
