Why Your Furnace Could be Blowing Cold Air

You notice your heating system turn on and you’re ready for a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want when it’s cold outside! 

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

  • Thermostat 

It may 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 as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it is not actually heating the air being produced, thus blasting cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable. 

  • Air Filter 

Typically air filters need to be changed monthly to keep them from growing dirty and clogged. If air filters aren’t swapped out often enough, the dirty air filter may restrict airflow into your heating equipment. If this takes place, it can overheat your equipment, causing the equipment to stop heating as a safeguard. 

  • Duct Work 

If your duct work has leaks, connection problems, or was not designed properly, it could permit warm air from the heating equipment to escape out. This would not only cause your furnace to produce 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 furnace could give off cold air. Call Service Experts Heating, Air Conditioning & Plumbing today and we’ll send a professional to diagnose your issue and get your home warm and comfy again in no time.
