As the weather changes, the more you feel the colder air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Mechanicsburg home, it’s time to reach out to H & H Service Company. Sometimes a lack of warm air from your gas furnace means a big repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had routine maintenance completed on your gas furnace recently and you’ve overlooked changing your air filter, either could indicate 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 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, specifically with older furnaces, for a gust of air to extinguish a pilot light. Other reasons for an extinguished pilot light are faulty 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 properly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and leave you in the cold.
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 even reaches the vents throughout the home.
