As the seasons change, the more you feel the cooler air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Bossier City home, it’s time to contact Central Aire Heating & A/C Inc. Occasionally the loss of warm air from your gas furnace means a major repair, but often it can be an easy fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, either could signal why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace may overheat and cause the burner to shut down.
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, especially with older models, for a gust of air to smother a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean problems 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
When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it can get to the vents.
