Why Your Furnace Could be Blowing Cold Air

You listen to your HVAC system kick on and you’re anticipating a comfortable blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather! 

There are a couple reasons why your heating equipment could be giving off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the culprit. 

  • Thermostat 

It could sound silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Make sure the system is set to “auto instead of “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it isn’t really heating the air coming out, thus blowing cold air. Changing it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfortable. 

  • Air Filter 

The majority of air filters need to be changed every month to avoid them from growing dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may impede airflow into your heating equipment. If this happens, it can overheat your furnace, causing the system to stop heating as a safeguard. 

  • Duct Work 

If your duct work contains leaks, connection troubles, or was designed incorrectly, it could allow warm air from the heating system to leak out. This would not only cause your furnace to blow cold air, it could actually run up your energy bills since your furnace is heating non-living space, and will have to work more to keep your home warm. 

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