Why Your Furnace Could be Blowing Cold Air

You notice your furnace start up and you’re expecting a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in freezing temperatures! 

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

  • Thermostat 

It could seem silly, but the thermostat is the first thing you want to look at. 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 really heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and cozy. 

  • Air Filter 

Typically air filters need to be changed monthly to prevent them from becoming dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may impede airflow into your heating system. If this takes place, it can overheat your system, causing the equipment to stop heating as a safety precaution. 

  • Duct Work 

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