As the seasons change, the more you feel the colder air blowing outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Norco and St. Charles Parish home, it’s time to contact Mayeuxs AC & Heating. Once in a while the loss of warm air from your gas furnace results in a major repair, but a lot of time it can be a simple fix. Here are some of the main 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 routine maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace could overheat and shut down its burner.
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, particularly with older models, 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 mean problems 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 struggle to stay lit and leave you in the cold.
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 can get to the vents.
