Why Your Furnace Could be Blowing Cold Air

You notice your heating system kick on and you’re ready for a cozy blast of warm air, but instead all you get is cool air blowing. That’s no good in the freezing weather! 

There are a handful of reasons why your heating system could be putting off cold air. Service Experts Heating, Air Conditioning & Plumbing is here with some of them to help you find the culprit. 

  • Thermostat 

It could sound silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air coming out, thus blowing cold air. Changing it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfortable. 

  • Air Filter 

Typically air filters need to be changed once a month to prevent them from becoming dirty and clogged. If your filters aren’t changed often enough, the dirty air filter may restrict airflow into your heating system. If this happens, it can overheat your equipment, causing the system to stop heating as a safety precaution. 

  • Duct Work 

If your duct work has leaks, connection problems, or was not designed correctly, it could permit warm air from the heating system to seep out. This would not only cause your furnace to give off 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 comfortable.
