As the weather changes, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Opelika home, it’s time to reach out to Farnell Mechanical, Inc.. Occasionally the loss of warm air from your gas furnace means a major repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of warming up your house.
Your furnace may be overheating
If you haven’t had regular maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might overheat and shut down its burner.
Your pilot light may have gone out
It could be that 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, specifically with older furnaces, for a breeze to smother 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 result in 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 reduce the warmth inside your house.
Your ducts may not be properly sealed
If your ducts aren’t sealed properly 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.
