Why Your Furnace Could be Blowing Cold Air

You notice your heating system kick on and you’re ready for a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in freezing temperatures! 

There are a few reasons why your heating equipment could be giving off cold air. A1 Chesney Service Experts is here with a few of them to help you detect the problem. 

  • Thermostat 

It could seem silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it is not actually heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and comfortable. 

  • Air Filter 

Most air filters need to be changed monthly to prevent them from getting dirty and clogged. If your filters aren’t swapped out 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 measure. 

  • Duct Work 

If your duct work has leaks, connection troubles, or was designed incorrectly, it could let warm air from the heating equipment to seep out. This would not only cause your furnace to give off cold air, it could actually run up your utility bills since your furnace is heating non-living space, and will have to work overtime to keep your home comfortable. 

There are multiple other reasons that your heating system could give off cold air.
