No, Your Furnace Should NOT Be Blowing Cold Air


It’s getting rather chilly out there, so of course, the last thing you need in your home is another air conditioner! See, your furnace should definitely not be blowing cool air so, if it is, there’s definitely a cause for concern.

There are a number of things that can lead to cool air blowing from your furnace, and below, we have listed some of them for you. All you have to do is keep reading to find out more, and of course, remember to schedule your HVAC services in Round Rock, TX with our team soon!

So, What’s the Deal?

Like we mentioned above, there are a number of reasons why your furnace might be blowing cool air, such as:

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 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.

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.

Schedule Your Repairs ASAP

If your furnace seems to be acting more like an air conditioner than a heater, it is definitely time to call in a certified HVAC professional for repairs. Trust us, you don’t want to wait! Waiting will only make matters worse, which we know is definitely not something you want!

And yes, there may be plenty of amateurs willing to provide these services for a fairly cheap price, but remember, sometimes an attempt to save money could end up costing you much more in the long run. Therefore, it is always better to call in a pro and get the job done right the first time around.
