Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Dallas and Atlanta surrounding areas home, it’s time to contact Innovative Mechanical, LLC. Sometimes an absence of warm air from your gas furnace results in a large repair, but often it can be a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had regular maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace could 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, especially with older systems, for a breeze 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 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 may be losing a lot of heated air before it ever reaches your vents.
