Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Cedar Rapids home, it’s time to contact Ilten's Incorporated. Occasionally a lack of warm air from your gas furnace results in a big repair, but many times it can be a simple 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 may 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, both could be the reason why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a gust of air to put out 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 mean challenges 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 not be able to bring warmth to your home.

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 even reaches the vents throughout the home.
