4 Common Furnace Problems and How to Spot Them

November 29, 2018

Keeping your furnace running properly in your Fayetteville, North Carolina, home is vital as the cold weather begins to approach. Making sure your furnace is operating at its peak efficiency involves being able to spot possible problems that can make it work harder than it should or put it at risk of a possible breakdown. Here are four of the most common furnace issues you may encounter. Read on to learn more about how you can spot these issues.

A Slipped or Frayed Belt

When belts are worn out from normal wear and tear, they need to be replaced. Once they have become damaged enough to affect your furnace’s function, you will begin to hear squealing when it’s running.

Clogged Air Filter

As dirt and debris move through your system, it will be stopped by your furnace filter. Your filter should be replaced on a regular basis. If it is not, there is a risk it will become clogged and reduce the airflow. If you notice overall reduced air coming from your vents, or the hot air only comes out for a short time, it may be time to replace your filter.

Thermostat Malfunctions

When your thermostat is not functioning properly, it will seem cold even if the temperature is set right. This could mean the thermostat needs to be replaced or there is a problem with the power supply to it.

Worn Ball Bearings

Ball bearings can wear out over time or become damaged as the furnace is used. You will notice a problem with the bearings if you hear scraping sounds coming from your furnace. This repair will need to be made by an HVAC technician and should not be attempted on your own. If you hear this noise, immediately shut down your furnace and call for repair.

If you think you may have a problem with your furnace, don’t wait for it to get worse. Contact the HVAC repair technicians at Cape Fear Air Conditioning, Heating & Electrical Company, Inc. at 910-216-9394 today.
