Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the colder air blowing outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Chadron home, it’s time to contact MPC Heating & Cooling. Sometimes the loss of warm air from your gas furnace calls for a large repair, but many times it can be a simple fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

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, either could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.

Your pilot light may have gone out

Sometimes 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, particularly with older furnaces, for a gust of air to put out a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 properly 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 sealed properly 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.
