As the temps change, the more you feel the colder air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Hodgenville home, it’s time to reach out to Phelps Heating & Cooling. Occasionally a lack of warm air from your gas furnace results in a big 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 making your home warm and cozy.
Your furnace could be overheating
If you haven’t had routine maintenance completed on your gas furnace recently and you’ve forgotten to change 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. If that happens, the furnace might 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 credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older furnaces, for a draft to extinguish a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in 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 battle to stay lit and reduce the warmth inside your house.
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 might be losing a lot of heated air before it ever reaches your vents.
