Furnaces are essential components of every home, providing necessary heat during the cold winter months. However, like all mechanical systems, furnaces can experience problems that require repairs. To help you get to know your furnace a bit better, here are some of the most common furnace problems and what they could mean.

1. Dirty Filter

Your furnace’s air filter is responsible for catching dirt, dust, and other airborne particulates that otherwise would accumulate in the system and cause breakdowns. A dirty filter can drastically reduce the efficiency of your furnace by restricting proper airflow.

2. Pilot Light Issues

Gas furnaces use a pilot light to ignite the main burner. If the light is out, your furnace won’t work. In some cases, the pilot light may be lit, but the color may be yellow or orange instead of blue, which could indicate that the oxygen level is too low and needs to be adjusted.

3. Cracked Heat Exchanger

The heat exchanger is the part of your furnace that helps to transfer heat from the burning fuel to the air being blown through your home. If this component cracks, it can allow potentially dangerous and harmful gases, like carbon monoxide, to escape into your home. You may notice a musty odor or soot around the furnace if this is occurring. Unexplained health problems may also be signs of a cracked heat exchanger.

4. Not Blowing Air

If your furnace is running but not blowing air, there could be a few possible causes. The blower motor may be broken, or the fan belt may need to be replaced. Additionally, the limit control switch or thermostat could be faulty and need to be repaired or adjusted.
