Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Bossier City home, it’s time to call Brooks Heating and Air Conditioning. Sometimes an absence of warm air from your gas furnace calls for a major repair, but a lot of time it can be a simple fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had regular maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, both could indicate 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 might overheat and shut down its burner.

Your pilot light may have gone out

It could be that 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 causes of an extinguished pilot light are faulty 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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 may be losing a lot of heated air before it ever reaches your vents.
