Why Is My Heater Blowing Cold Air?

You notice your HVAC system kick on and you’re anticipating a comfortable blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

Why is my heater blowing cold air

There are a few reasons why your heating equipment could be giving off cold air. Air Factory Heating & Cooling can help you find the culprit and fix the problem!

Thermostat

It might sound 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 and not “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it isn’t heating the air being released, thus blasting cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.

Air Filter

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

Duct Work

If your duct work has leaks, connection problems, or was designed incorrectly, it could permit warm air from the heating equipment to leak out. This would not only cause your heating equipment to blow cold air, it could significantly run up your energy bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home warm.
