Why Is My Furnace Blowing Cool Air?

cold-manYou depend on your furnace for endless heat during the winter. Temperatures here in Western Michigan can dip well into the thirties, so as you can imagine, the last thing you’d want is for your furnace to blow cool air! If the air coming from your furnace is not an appropriate temperature, you definitely have a problem on your hands! If you’ve noticed cool air coming from your vents, it’s time to schedule your furnace repair in Rockford, MI.

There are a number of potential reasons as to why your system is blowing cool air, some being more significant than others. Only a trained HVAC technician can accurately diagnose and correct the problem. In any case, it’s best to schedule your repairs as soon as possible to avoid causing further damage to the system. Below, we have outlined some of the potential causes of cool air. 

Your Furnace Might Be Blowing Cool Air Because:

There is an issue with your thermostat

Sometimes the problem isn’t with the furnace itself, but rather with the thermostat. If your thermostat is malfunctioning, it might be misreading indoor temperatures or it might not be properly regulating the temperature in the furnace.

We also recommend checking your thermostat to see if its set to “AUTO” rather than “ON.” When it is set to “ON,” the fan will blow continuously, even if the furnace isn’t actually heating the air.

Your air filter is clogged

A clogged air filter can cause significant problems if ignored, one of which is a lack of heat. A dirty air filter restricts airflow into your furnace, causing it to overheat. When this happens, your system will shut down as a safety measure. The fan, however, will continue to blow air to cool down the heat exchanger.  Changing your clogged air filter might just be the way to restore heat to your home.

There are broken heating elements

When any of the elements responsible for heating air are broke, you can expect cool air from your furnace. A professional can inspect each element of your furnace to pinpoint the source of the problem.

There is a ductwork breach

When there is a breach in the ductwork, warm air will leak from the system. In addition, a breach will cause air from other parts of the house, most of it colder than air from the furnace, to enter the system causing a drop in temperature. A professional and locate and seal any ductwork breaches.
