Gas furnace blowing cold air
If your gas furnace is blowing cold air, it could be due to several reasons. One of the most common causes is a malfunctioning thermostat. If your thermostat is not working properly, it may not signal the furnace to turn on the heat. Another possible cause could be a clogged air filter. A dirty air filter can restrict airflow, causing the furnace to overheat and shut off.
A faulty ignition system or a malfunctioning pilot light could also be the culprit. It’s important to have a professional HVAC technician inspect and diagnose the issue to ensure proper repair and safety. Regular maintenance and cleaning of your furnace can help prevent these issues from occurring in the first place. Don’t hesitate to call a licensed professional if you’re experiencing issues with your gas furnace.
