Why Your Furnace Could be Blowing Cold Air

You hear your HVAC system turn on and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not what you want when it’s cold outside!

There are a handful of reasons why your furnace could be blowing cold air. Service Experts Heating & Air Conditioning is here with some of them to help you locate the issue.

• Thermostat

It may seem silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it isn’t really heating the air being released, thus blasting cold air. Turning 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

The majority of air filters need to be changed every month to avoid them from getting dirty and clogged. If your filters aren’t swapped out often enough, the clogged air filter may impede airflow into your heating system. If this occurs, it can overheat your equipment, causing the equipment to stop heating as a safeguard.

• Duct Work

If your duct work includes leaks, connection issues, or was not designed properly, it could allow warm air from the furnace to escape out. This would not only cause your heating system to produce cold air, it could seriously run up your energy bills since your furnace is heating non-living space, and will have to work overtime to keep your home warm.
