Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cool air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Denton home, it’s time to contact Oak Point Heating and Air LLC. Sometimes a lack of warm air from your gas furnace results in a large repair, but a lot of time 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 might be overheating

If you haven’t had routine maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, each could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace could overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes 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, especially with older furnaces, for a gust of air to extinguish 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 cause issues 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 fight to stay lit and reduce the warmth inside your house.

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 can get to the vents.
