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 feel is cool air blowing. That’s not what you want when it’s cold outside!

There are a few reasons why your furnace could be blowing cold air. Service Experts Heating, Air Conditioning & Plumbing is here with a couple of them to help you find the problem.

    • Thermostat

It may seem silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Make sure 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 heating the air being produced, thus blowing cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and cozy.

    • Air Filter

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

    • Duct Work

If your duct work contains leaks, connection troubles, or was designed incorrectly, it could allow warm air from the heating system to seep 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 more to keep your home at the desired temperature.

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