Why Your Furnace Could be Blowing Cold Air

You listen to your heating system start up and you’re expecting a comfy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!

There are a few reasons why your furnace could be putting off cold air. Knochelmann Service Experts Heating & Air Conditioning is here with some of them to help you detect the culprit.

• Thermostat

It might feel 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 HVAC system will blow continually, even when it isn’t heating the air being produced, thus blowing cold air. Changing it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and cozy.

• Air Filter

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

• Duct Work

If your duct work has leaks, connection troubles, or was not designed correctly, 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 significantly run up your energy bills since your heating system is heating non-living space, and will have to work harder to keep your home comfortable.
