No, Your Furnace Should Not Be Blowing Cool Air


Here’s the deal: when you bought your furnace, you did not agree to have a second air conditioner installed in your home. See, if your furnace is blowing cool air, it is definitely a cause for concern — fortunately, you needn’t worry too much.

For your convenience, we have listed some of the reasons why this might be happening. All you have to do is keep reading to find out more… and of course, remember to call our team of furnace repair experts when you have a problem!

So, Why Is My Furnace Blowing Cool Air?

Like we mentioned above, there are a number of issues that can cause your furnace to blow cool air, including:

Thermostat Troubles

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 it’s 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.

A Clogged Air Filter

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.

Broken Heating Elements

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

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. Fortunately, a certified HVAC professional can locate and seal any ductwork breaches.

Call in a Professional

If your furnace is in need of repairs, do not hesitate to call in a certified HVAC professional for help. Only a professional has the tools, training, and expertise to safely and correctly handle the complex needs of your system, the first time around.

And yes, there may be plenty of amateurs willing to service your system for a fairly cheap price, but remember, sometimes an attempt to save money could end up costing you much more in the long run. Trust us, when it comes to your comfort and your budget, you don’t want to take any risks!
