Why Your Furnace Could be Blowing Cold Air

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

There are a few reasons why your heating equipment could be putting off cold air. Stevenson Service Experts is here with some of them to help you find 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. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it is not actually heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy.

    • Air Filter

Typically air filters need to be changed every month to keep them from becoming dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may restrict airflow into your heating equipment. If this occurs, it can overheat your system, causing the furnace to stop heating as a safeguard.

    • Duct Work

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

There are several other reasons that your heating system could blow cold air.
