Fortunately, we live in Texas, which means that we don’t have to worry too much about cold, snowy winters. But even still, you expect that your heating system works as it’s supposed to, and therefore, if your furnace is blowing cool air, it is definitely a cause for concern.
There are a number of reasons why your furnace might be blowing cool air, and below, we have listed some of them for you. All you have to do is keep reading to find out more… and remember to call our team when you need furnace repair in San Antonio.
So, What’s the Deal?
Like we mentioned above, there are a number of issues that can cause your furnace to blow cool air. These include:
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.
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.
