Why Your Furnace Could be Blowing Cold Air

You notice your heating system kick on and you’re expecting a cozy blast of warm air, but instead all you feel is cool air blowing. That’s no good in the freezing weather! 

There are a few reasons why your furnace could be blowing cold air. Air Engineers Service Experts is here with a few of them to help you find the culprit. 

  • Thermostat 

It could sound silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Make sure the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it isn’t heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the furnace 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 monthly to avoid them from getting dirty and clogged. If your filters aren’t changed often enough, the dirty air filter may obstruct airflow into your heating system. If this happens, it can overheat your system, causing the furnace to stop heating as a safeguard. 

  • Duct Work 

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

There are many other reasons that your furnace could produce cold air.
