Why Your Furnace Could be Blowing Cold Air

You listen to your furnace turn on and you’re ready for a cozy blast of warm air, but instead all you have is cool air blowing. That’s not preferable when it’s cold outside!

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

    • Thermostat

It might seem silly, but the thermostat is the first thing you want to look at. 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 furnace will blow continually, even when it isn’t heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfy.

    • Air Filter

Typically air filters need to be changed once a month to avoid them from growing dirty and clogged. If they aren’t replaced often enough, the clogged air filter may obstruct airflow into your furnace. If this occurs, it can overheat your furnace, causing the furnace to stop heating as a safety measure.

    • Duct Work

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