Is a Bad Blower Motor Affecting Your Anderson Creek, NC Home Comfort?

August 26, 2022

Your Anderson Creek, NC home’s HVAC system is complex, with many parts to make it work properly. The blower motor is responsible for drawing air into the system and circulating it back into your home. Discover how a bad blower motor may reduce your home’s comfort and why they go bad.

No Airflow

No air coming from your supply vents is a telltale sign you have an issue with your blower motor. Without any air coming from your vents, your home will never achieve your desired temperature.

There are other issues that may cause a complete airflow block, such as a frozen evaporator coil. Have a professionally trained technician troubleshoot the issue for an accurate repair plan.

Reduced Supply Airflow

Before you end up with the system failing to circulate air at all, you’ll likely experience reduced airflow. This happens when the blower motor begins spinning more slowly as it loses its ability to rotate effectively. Less air coming from your vents means your home won’t heat or cool evenly and will require longer cycles.

Again, other issues may cause reduced airflow, such as a clogged air filter. Work through troubleshooting the issue, including checking your air filter, to avoid unnecessary repairs.

Unusual Sounds

Part of the comfort of your home is controlling the sounds you hear. Your HVAC system should run nearly silently when it’s working properly.

A faulty blower motor may produce some loud sounds that will disturb your home’s environment. These sounds may include a loud screeching or squealing, rattling, banging or clanking. These sounds may originate from worn bearings, a broken or loose part, or older units may have loose fan belts.

Why Blower Motors Fail

Blower motors will eventually fail due to age, but they’ll usually last the full service life of your HVAC system. Dirt accumulating in the motor from neglected HVAC maintenance commonly causes premature failures.

If you think you have a failing blower motor, have it professionally inspected and replaced. Call to schedule your heat or AC repair with the experts at Cape Fear Air Conditioning today.
