Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Brighton home, it’s time to contact D & D Heating & AC. Occasionally the loss of warm air from your gas furnace results in a big repair, but a lot of time it can be an easy fix. Here are several 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 recently and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a draft to extinguish 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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 ever reaches your vents.
