Why Your Furnace Could be Blowing Cold Air

You listen to your furnace start up and you’re expecting a cozy blast of warm air, but instead all you feel 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. Service Experts Heating & Air Conditioning is here with a couple of them to help you find the culprit. 

  • Thermostat 

It may seem 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 and not “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it isn’t heating the air being produced, thus blasting cold air. Turning it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy. 

  • Air Filter 

Most air filters need to be changed once a month to prevent them from growing dirty and clogged. If your filters aren’t changed often enough, the soiled air filter may impede airflow into your heating equipment. If this takes place, it can overheat your system, causing the equipment to stop heating as a safeguard. 

  • Duct Work 

If your duct work includes leaks, connection troubles, or was not designed correctly, it could let warm air from the heating equipment to escape out. This would not only cause your heating equipment to give off 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 at the desired temperature. 

There are many other reasons that your heating system could give off cold air. Call Service Experts Heating & Air Conditioning today and we’ll send a professional to diagnose your issue and get your home warm and comfortable again in no time.
