Why Your Furnace Could be Blowing Cold Air

You hear your heating system turn 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 couple reasons why your heating system could be giving off cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you find the issue. 

  • Thermostat 

It might sound silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, 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 really heating the air coming out, thus putting off 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 comfy. 

  • Air Filter 

Typically air filters need to be changed monthly to avoid them from growing dirty and clogged. If air filters aren’t changed often enough, the soiled air filter may restrict airflow into your heating equipment. If this happens, it can overheat your equipment, causing the furnace to stop heating as a safety measure. 

  • Duct Work 

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

There are several 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 problem and get your home warm and comfortable again in no time.
