With Ottawa’s winter approaching, it’s time for your furnace to battle the cold. If you’ve fired up your furnace only to find it blowing cold air, we understand your concern. Luckily, there are a few troubleshooting steps you can take to identify the issue and get your furnace back in shape.
1. Check Your Thermostat
Start with your thermostat. If it’s set to “ON,” the fan runs continuously, which means that when the furnace shuts off, cold air will circulate throughout your home. Switch the fan setting to “AUTO” so it only runs when the furnace is heating. This simple adjustment can often resolve the cold air issue.
2. Dirty or Clogged Air Filter
A dirty or clogged air filter can restrict airflow, potentially causing the furnace to blow cold air. Fortunately, cleaning or replacing the air filter is an easy task for homeowners. This small step can ensure that your furnace runs properly and optimally.
3. Overheated Furnace
If your thermostat is correctly set and your air filter is clean, but your furnace is still blowing cold air, it might be overheating. Furnaces have a safety switch that trips when the system gets too hot, causing it to push cold air through your home. In this case, it’s best to contact your local HVAC company.
4. Pilot Light Issues
If your furnace is older, it probably relies on a pilot light to ignite the main burner. If your furnace is blowing cold air, the pilot light may have extinguished. Relighting it is generally simple, and you can often find instructions on the appliance itself. However, if the pilot light continues to go out, contact your trusted HVAC company to resolve the issue.
