Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Odessa home, it’s time to call Redhawk Heating & Air Conditioning. Occasionally an absence of warm air from your gas furnace results in a large repair, but many times it can be a small fix. Here are several reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace could be overheating

If you haven’t had routine maintenance completed on your gas furnace lately and you’ve neglected to replace your air filter, either could be the reason 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 could overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable 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, particularly with older furnaces, for a gust of air to put out a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean 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 fight to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
