Signs Your HVAC Blower Motor Needs to Be Replaced

Winters and summers can be really harsh and without a properly functioning heating and cooling system, your home will fail to provide comfort. A malfunctioning furnace or failed air conditioner is the last thing you want when temperature plummets or soar. To keep your HVAC system functional throughout the year, regular maintenance is important. Due to several reasons such as age or poor upkeep, the heating or cooling system could fail to maintain a comfortable indoor environment.  Your system could also malfunction if there’s an issue with the blower motor. As one of the most important elements of your HVAC system, blower motor should stay in top working condition.

It is responsible for blowing the conditioned air through the vents in your home. The blower motor circulated the cool air created by your air-conditioner. This crucial electrical component plays a vital role in maintaining the temperature level dictated by the thermostat. The motor works to spin a fan for moving air through the ducts and vents in your home. So, if your HVAC system is showing unusual behavior, possibly blower motor is malfunctioning. Similar to other electrical parts, the blower motor is also susceptible to mechanical damage. It suffers wear and tear over time and needs replacement. So, if your air conditioner or furnace is creating trouble, take a look at the motor. Here are some signs that your blower motor needs replacement.

Poor or No Airflow from Air Vents

If your AC or furnace lacks proper air flow, it’s a clear sign that your blower motor has a problem. Sometimes, poor airflow is the result of dirt buildup that can clog the filter. Other issues like bad capacitor, leaky air duct, or system age can also be the cause. While some issues can be fixed with a repair, others might need motor replacement. When blower motor reached the end of its service life, it gets hard to push air through the ducts. So, get the motor check and install a new motor blower if you’re experiencing weak airflow.

Skyrocketing Energy Bills

Another sign of faulty motor is unusually high energy bills. When blower motor gets worn-out, it has to work harder to properly circulate conditioned air throughout your home. As a result, the HVAC system consumes more energy, increasing your utility bills. If the motor is not clogged with dirt, possibly aging is the issue. With age, the motor starts wearing down. High energy bills could be a sign of a leak in the air duct or a deteriorating blower motor.

Weird Smell or Strange Noises

When something goes wrong within the HVAC system, you could hear strange noises or odd smells. Your furnace could make squealing, screeching, rattling, or clanking sound if the blower motor is malfunctioning. These noises could be due to other issues also such as bearing problems or belt issues. However, banging sounds usually indicate that the blower motor needs to be replaced. Other signs of faulty motor include overheating bower motor or burning smell coming from vents when you turn on the system.
