As the weather changes, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Keokuk home, it’s time to call WM J Kraus & Son. Sometimes an absence of warm air from your gas furnace means a big repair, but often it can be an easy fix. Here are several reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had routine maintenance completed on your gas furnace for some time and you’ve overlooked changing your air filter, either could be the reason why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace might overheat and cause the burner to shut down.
Your pilot light may have gone out
It could be that 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, particularly with older models, for a breeze to extinguish a pilot light. Other factors when it comes to 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 properly 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
If your ducts aren’t properly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it can get to the vents.
