Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the colder air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Central Point home, it’s time to call Titan Heating & Air Conditioning. Occasionally a lack of warm air from your gas furnace calls for a major repair, but a lot of time 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 might be overheating

If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It could be that 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 models, for a gust of air to smother a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems 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

When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it even reaches the vents throughout the home.
