Why Your Furnace Could be Blowing Cold Air

You listen to your HVAC system turn on and you’re anticipating a comfortable blast of warm air, but instead all you have is cool air blowing. That’s no good in the freezing weather! 

There are a couple reasons why your furnace could be blowing cold air. Stevenson Service Experts is here with some of them to help you locate the issue. 

  • Thermostat 

It may feel silly, but the thermostat is the first thing you want to look at. It’s the first place any heating system technician will check, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air being produced, thus blasting cold air. Changing it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and comfortable. 

  • Air Filter 

Most air filters need to be changed every month to avoid them from becoming dirty and clogged. If your filters aren’t swapped out often enough, the soiled air filter may impede airflow into your heating equipment. If this occurs, it can overheat your system, causing the system to stop heating as a safeguard. 

  • Duct Work 

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

There are multiple other reasons that your furnace could blow cold air. Call Stevenson Service Experts today and we’ll send a technician to diagnose your issue and get your home warm and cozy again in no time.
