As the weather changes, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Manassas home, it’s time to call Air-Right Energy Design, Inc.. Occasionally an absence of warm air from your gas furnace results in a major repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.
Your furnace might be overheating
If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, either could signal why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.
Your pilot light may have gone out
Sometimes a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a breeze to put out a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause problems for your gas furnace, so can other furnace components if they aren’t appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and not be able to bring warmth to your home.
Your ducts may not be properly sealed
If your ducts aren’t properly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it can get to the vents.
