Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cooler air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your West Columbia home, it’s time to contact Tri City Fuel & Heating Co., Inc.. Once in a while an absence of warm air from your gas furnace means a large repair, but many times it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace could be overheating

If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve forgotten to change your air filter, both could be the reason why your furnace is blowing cool 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’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, specifically with older furnaces, for a gust of air to smother a pilot light. Other causes of an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in challenges 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 could be losing a lot of heated air before it can get to the vents.
