Why Your Furnace Could be Blowing Cold Air

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

There are a few reasons why your heating system could be blowing cold air. Epperson Service Experts is here with some of them to help you find the culprit. 

  • Thermostat 

It might sound silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, 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 heating system only blows when it’s truly heating the air to keep your home warm and cozy. 

  • Air Filter 

Most air filters need to be changed monthly to keep them from getting dirty and clogged. If air filters aren’t replaced often enough, the dirty air filter may obstruct airflow into your heating system. If this happens, it can overheat your system, causing the equipment to stop heating as a safety precaution. 

  • Duct Work 

If your duct work includes leaks, connection problems, or was designed incorrectly, it could permit warm air from the heating system to escape out. This would not only cause your heating system to blow cold air, it could significantly run up your energy bills since your heating system 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 blow cold air.
