Why Your Furnace Could be Blowing Cold Air

You listen to your furnace turn on and you’re ready for a comfy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather! 

There are a few reasons why your furnace could be putting off cold air. Service Experts Heating, Air Conditioning & Plumbing is here with a few of them to help you find the problem. 

  • Thermostat 

It might feel silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it isn’t really heating the air being released, thus putting off cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and cozy. 

  • Air Filter 

The majority of air filters need to be changed monthly to keep them from becoming dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may obstruct airflow into your heating equipment. If this takes place, it can overheat your system, causing the equipment to stop heating as a safety precaution. 

  • Duct Work 

If your duct work has leaks, connection problems, or was not designed correctly, it could allow warm air from the heating equipment to seep out. This would not only cause your heating system to give off cold air, it could seriously run up your energy bills since your heating system is heating non-living space, and will have to work more to keep your home comfortable. 

There are many other reasons that your heating equipment could blow cold air.
