Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Pekin home, it’s time to call Accurate Heating & Cooling LLC. 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 some of the main reasons your gas furnace might 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 recently 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 block air from flowing freely through your furnace. If that happens, the furnace may overheat and shut down its burner.

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 systems, for a gust of air to extinguish 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 mean challenges 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

If your ducts aren’t sealed properly or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
