As the seasons change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Omaha home, it’s time to contact Interstate Heating & Air Conditioning. Once in a while an absence of warm air from your gas furnace calls for a major repair, but a lot of time it can be an easy fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace could overheat and force the burner to shut down.
Your pilot light may have gone out
Sometimes 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, specifically with older models, for a breeze to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean 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 fight 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 ever reaches your vents.
