Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Erie home, it’s time to contact Patterson & Stirling Inc. Occasionally a lack of warm air from your gas furnace means a big repair, but many times it can be an easy fix. Here are several reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had regular maintenance completed on your gas furnace lately and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing cold air. A dirty air filter can block 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 credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, for a gust of air to smother a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause issues for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and leave you in the cold.

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 even reaches the vents throughout the home.
