Why Your Furnace Could be Blowing Cold Air

You notice your HVAC system kick on and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not what you want in freezing temperatures!

There are a handful of reasons why your heating equipment could be blowing cold air. Stevenson Service Experts is here with a couple of them to help you find the culprit.

    • Thermostat

It might sound silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Verify 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 produced, thus blowing cold air. Changing it to “auto” will make sure the heating equipment 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 once a month to prevent them from becoming dirty and clogged. If they aren’t replaced often enough, the dirty air filter may obstruct airflow into your heating equipment. If this takes place, it can overheat your furnace, causing the system to stop heating as a safety measure.

    • Duct Work

If your duct work has leaks, connection troubles, or was designed incorrectly, it could allow warm air from the furnace to leak out. This would not only cause your heating equipment to blow cold air, it could seriously run up your energy bills since your heating equipment is heating non-living space, and will have to work harder to keep your home warm.
