NO! Your Furnace Should NOT Be Blowing Cool Air!

NO! Your Furnace Should NOT Be Blowing Cool Air!

If you’ve ever noticed your furnace blowing cool air from time to time, you may just assume that it’s a part of its typical cycle, but that isn’t the case. Something is wrong, and you may need to fix or replace furnace in Dickson, TN. 


Here are some of the reasons that could be behind your heating problem:


The Furnace Isn’t Starting

One of the most common reasons why you may not be getting heat from your furnace is the fact that it isn’t starting up. A variety of factors can lead to such an issue: For gas furnaces, the pilot light could have gone out, and on other systems, there are also safety features to be aware of, such as the reset switch or flame sensor, that could be out of order.


Restricted Air Flow

Your furnace maintains a variety of controls to ensure that it doesn’t overheat. If a clogged air filter or other problems are restricting airflow, there won’t be enough air drawing heat away, causing your furnace to reach the safety shutoff temperature and continue blowing air to dissipate heat, even once it has cooled down quite a bit.


Damaged Ductwork

Your home’s ductwork is essential for the proper function of your furnace. Segments that have become disconnected can let substantial amounts of air out, making your home’s heating less effective. Even small rips and tears can add up, reducing the system’s efficiency and lowering temperatures throughout your home.


Thermostat Calibration

What may seem like a furnace issue could actually be a problem with your thermostat. If your thermostat isn’t properly calibrated, it may shut off your furnace even when your home is still cold. Luckily, professionals can quickly determine whether the thermostat or other control components are at fault and provide effective repairs or replacements.
