Why Your Furnace Could be Blowing Cold Air

You listen to your furnace turn on and you’re expecting a cozy 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 giving off cold air. Stevenson Service Experts is here with a few of them to help you detect the problem.

    • Thermostat

It could sound silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Verify 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 being produced, thus blowing cold air. Flipping it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and comfy.

    • Air Filter

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

    • Duct Work

If your duct work contains leaks, connection problems, 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 actually run up your energy bills since your heating equipment is heating non-living space, and will have to work more to keep your home at the desired temperature.

There are multiple other reasons that your furnace could blow cold air.
