Why Your Furnace Could be Blowing Cold Air

You hear your furnace start up and you’re ready for a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not what you want in freezing temperatures!

There are a couple reasons why your heating system could be putting off cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you find the culprit.

• Thermostat

It may sound 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 instead of “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it is not actually heating the air being produced, thus blowing cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and comfy.

• Air Filter

Typically air filters need to be changed monthly to prevent them from becoming dirty and clogged. If air filters aren’t swapped out often enough, the dirty air filter may restrict airflow into your heating system. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

• Duct Work

If your duct work has leaks, connection problems, or was designed incorrectly, it could let warm air from the furnace to seep out. This would not only cause your heating system to blow cold air, it could actually run up your energy bills since your furnace is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
