Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Wheeling home, it’s time to contact Local HVAC Repair & Service . Once in a while an absence of warm air from your gas furnace results in a large repair, but many times it can be an easy fix. Here are several reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had ongoing maintenance completed on your gas furnace for some time and you’ve neglected to replace your air filter, either could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace could overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a gust of air to smother a pilot light. Other factors when it comes to 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 issues 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 fight 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 ever reaches your vents.
