Airflow Matters: The Blower Motor in Your HVAC System

September 27, 2024

Does your home struggle to reach your desired temperature? Your HVAC blower motor could be to blame. 


Find out why this main component of your HVAC system can lead to significant airflow issues, signs that it’s starting to fail, and what you can do to preserve your equipment.


The Role of Your HVAC Blower

You can’t sustain proper airflow from your heating or cooling system without an efficient blower motor. This motor operates the fan inside your furnace, heat pump, or air conditioner so heat or cool air can fill your home. The blower motor will kickstart whenever your thermostat sends a signal that the space isn’t at the right temperature. 


Without a working motor, your airflow balance will be off. Your home won’t reach the ideal temperature and you’ll end up paying more in energy costs by continuing to operate a faulty motor. 


Common Signs of HVAC Blower Motor Failure

How can you tell if your HVAC blower motor isn’t working? Most homeowners will experience the following issues:


  • Strange sounds or smells coming from the heating or cooling unit
  • Increases in energy bills despite no change in monthly heating or cooling habits
  • Little to no air distribution from the vents

If your motor starts to fail, it could lead to other significant problems with your HVAC system. For example, the unit may continue to run to the point of overheating and damaging other internal components. Have a professional technician inspect your system at the first sign of a problem and they’ll recommend solutions. 


Tips for Preserving Your System’s Blower Motor

Blower motors can fail for several reasons, including electrical issues or normal wear and tear with age. Paying for a motor replacement will be inevitable if you don’t properly care for your system.


Make sure that you regularly change your HVAC air filter since debris buildup can restrict your airflow and cause the motor to overwork. In addition, check that all of your home’s vents are open and not blocked by furniture or other large objects. Simple steps like these will help your furnace or air conditioner work more efficiently and maintain strong airflow. 


It’s worth investing in annual HVAC system maintenance to check for other issues that may cause your motor to fail, including:


  • Worn-out bearings
  • Faulty electrical components
  • Temperature control problems
  • Leaky or damaged air ducts

Experts will perform a thorough inspection of your HVAC system and detect common problems that require repairs. A tune-up is the best way to prevent damage to your motor blower and keep your HVAC equipment in excellent condition.
