4 Signs Your Furnace Has a Failing Blower Motor in Knoxville, TN

The blower motor in your furnace is responsible for circulating heat throughout your Knoxville, TN, home during the winter. When it doesn’t function properly, it won’t be able to do its job. Here are four signs your furnace has a failing blower motor and why you should schedule a repair or replacement right away:

Strange Noises

If you hear strange noises from your furnace, it’s a sign that the blower motor is starting to fail. These noises can range from a gentle hum to a loud banging. For most HVAC systems, these noises are signs that you need to schedule a repair.

Decreased Airflow

Another sign that your furnace blower motor is failing is decreased airflow. If you turn on your furnace and notice that the airflow is weaker than usual, it likely means the blower motor is struggling to circulate air. This could make your home feel uncomfortable and can cause your energy bills to increase.


Short-cycling is when your furnace turns on and off more frequently than normal, which usually happens because the blower motor is overworking itself to circulate air. If you notice your furnace is short-cycling, call a professional so they can inspect the blower motor and make any necessary heating repairs.

Higher Energy Bills

Higher energy bills are a common sign that your furnace blower motor is failing. The harder it has to work to circulate air, the more energy it uses, which can drive up costs. If you’ve noticed a sudden spike in your energy bills, especially since your last HVAC maintenance appointment, call a professional for an inspection.
