Why Your Furnace Could be Blowing Cold Air

You listen to your furnace kick on and you’re expecting a comfortable blast of warm air, but instead all you have is cool air blowing. That’s not what you want when it’s cold outside! 

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

  • Thermostat 

It may feel silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it isn’t heating the air coming out, thus putting off cold air. Flipping it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and cozy. 

  • Air Filter 

Most air filters need to be changed every month to prevent them from growing dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may impede airflow into your heating equipment. If this takes place, it can overheat your system, causing the system to stop heating as a safety measure. 

  • Duct Work 

If your duct work contains leaks, connection issues, or was not designed properly, it could permit warm air from the heating equipment to seep out. This would not only cause your heating system to give off cold air, it could significantly run up your heating bills since your furnace is heating non-living space, and will have to work harder to keep your home warm. 

There are multiple other reasons that your heating equipment could blow cold air.
