Why Your Furnace Could be Blowing Cold Air

You notice your heating system kick on and you’re expecting a comfy blast of warm air, but instead all you feel is cool air blowing. That’s no good in freezing temperatures!

There are a few reasons why your heating system could be putting off cold air. Stevenson Service Experts is here with some of them to help you find the culprit.

    • Thermostat

It may feel silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it is not actually heating the air coming out, thus blowing cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfy.

    • Air Filter

The majority of air filters need to be changed once a month to avoid them from growing dirty and clogged. If air filters aren’t swapped out often enough, the soiled air filter may restrict airflow into your heating equipment. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safety precaution.

    • Duct Work

If your duct work includes leaks, connection troubles, or was designed incorrectly, it could let warm air from the heating equipment to escape out. This would not only cause your furnace to blow cold air, it could seriously run up your utility bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
