Why Your Furnace Could be Blowing Cold Air

You listen to your HVAC system turn on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not preferable when it’s cold outside! 

There are a handful of reasons why your heating equipment could be giving off cold air. Stallion Heating and Air Conditioning is here with a few of them to help you detect the problem. 

  • Thermostat 

It could feel silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it is not actually heating the air being produced, thus blasting cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfy. 

  • Air Filter 

Typically air filters need to be changed every month to avoid them from growing dirty and clogged. If your filters aren’t replaced often enough, the clogged air filter may restrict airflow into your furnace. If this occurs, it can overheat your system, causing the system to stop heating as a safety precaution. 

  • Duct Work 

If your duct work includes leaks, connection issues, or was not designed properly, it could permit warm air from the furnace to seep out. This would not only cause your heating system to blow cold air, it could actually run up your heating bills since your heating system is heating non-living space, and will have to work more to keep your home at the desired temperature. 

There are several other reasons that your heating system could blow cold air.
