As the seasons change, the more you feel the cooler air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Rocky Mount home, it’s time to reach out to Davis Heating & Air Conditioning. Occasionally a lack of warm air from your gas furnace calls for a major repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had regular maintenance completed on your gas furnace for some time and you’ve forgotten to change your air filter, either could signal why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace may 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, specifically with older systems, for a gust of air to put out 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 result in issues 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 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 could be losing a lot of heated air before it ever reaches your vents.
