Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Marshfield home, it’s time to reach out to House of Heating Incorporated. Once in a while an absence 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 some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had routine maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, the furnace might overheat and cause the burner to shut down.

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 systems, for a breeze to smother a pilot light. Other factors when it comes to an extinguished pilot light are defective 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 appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
