As the weather changes, the more you feel the cool air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Justin home, it’s time to contact Pepper AC & Htg Inc. Once in a while an absence of warm air from your gas furnace means a big repair, but often it can be a small fix. Here are several reasons your gas furnace might be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace may overheat and force the burner to shut down.
Your pilot light may have gone out
It’s probable a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, for a gust of air to extinguish 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 result in issues 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 battle to stay lit and not be able to bring warmth to your home.
Your ducts may not be properly sealed
When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it can get to the vents.
