Why Your Furnace Could be Blowing Cold Air

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

There are a couple reasons why your heating system could be giving off cold air. Norrell Service Experts is here with some of them to help you locate the issue. 

  • Thermostat 

It might feel silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto as opposed to “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 blowing cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and cozy. 

  • Air Filter 

Typically air filters need to be changed every month to keep them from getting dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may obstruct airflow into your furnace. If this takes place, it can overheat your system, causing the furnace to stop heating as a safety precaution. 

  • Duct Work 

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

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