How to know what is wrong with your furnace?

The simplest answer is to trust the professionals but there are common reasons furnaces need repair. Identifying the signs of these issues may save you time, frustration, and money. If minor issues are repaired early enough they prevent major issues or even complete replacement of your furnace. 

Common Signs Something is Wrong With Your Furnace

Air Filter

Your furnace’s air filter keeps your furnace clean and prevents it from filling up with dust and debris. In order to operate efficiently, your furnace needs to have a steady source of clean air to distribute heat efficiently through your home. Restricted airflow from a full air filter forces the furnace to work harder and more frequently.

Your filter is easy to change, and you can buy most furnace air filters at your local hardware store.  During repairs and maintenance, our technicians can show you the filter location. Regularly checking and changing your filter is the best supplemental maintenance you can perform between annual HVAC inspections.  


If it seems like your furnace is running non-stop, first check your thermostat to make sure that the fan is set to “auto” and not “on.” If that doesn’t help, there may be a disconnect between your thermostat and your home’s heating system. 

Heat Exchanger

If your system is overtaxed, this primary component may fail. Lack of maintenance, overuse, and dirt in the system all play a role in a broken heat exchanger. If your carbon monoxide detector goes off, it’s often a sign that your heat exchanger might have cracks in it and is causing carbon monoxide to leak.

Short Cycling

If it seems like your furnace turns on and then turns off very quickly without heating your home, then it is experiencing short cycling. This can be caused by a number of factors including an old furnace filter or a broken pilot light. 


Squealing sounds coming from the furnace often indicate a damaged, frayed, or broken blower belt. New belts help to quiet the furnace and restore efficiency.


This term refers to when your furnace runs more frequently than normal. There are many causes for this issue and repairs should be made immediately. Clogged filters, improper airflow, and other issues may cause over-cycling. If you notice a sudden spike in energy bills without an increase in usage, it’s likely that your system is not running efficiently and is using more energy than it needs to in order to heat your home, and repairs can restore your furnace to peak efficiency. 

Metallic Sounds

Anytime your furnace sounds different than normal, you should call the professionals immediately. Metallic noises may be as minor as worn bearings or a stretched belt. The longer you wait the more likely it is these minor issues will snowball into a bigger problem.
