Faulty AC blower motors can wreak havoc on your HVAC system, so here are some red flags to keep an eye out for!

AC repairs in northern Utah

Every AC system’s blower motor is meant to help the system move air throughout the rest of the air conditioner’s components—until it’s ready to enter your home. Without a properly functioning blower motor, your AC simply won’t be capable of providing its necessary cooling effect.

It’s important for northern Utah home and business owners to understand how there are several different types of blower motors, and that there are certain red flag warning signs that you should know about in terms of recognizing faults and other malfunctions.

Below we’ll be detailing what you need to be on the lookout for when it comes to your AC system’s blower motor!

Understanding Your AC System’s Type Of Blower Motor

The first and foremost thing that you should know about in terms of your AC’s blower motor is what type of motor it is.

Most standard AC systems entail single-speed blower motors, which means that it’ll simply be on or off and function at the same speed while operating. There are also variable-speed and two-speed motors that are available for home and business owners.

Two-speed fans are as they seem with two speed settings, and variable-speed motors will offer many different speed options to choose from. Most of today’s high-efficiency AC systems either have variable or two-speed fans.

Knowing what type of blower motor you have will help you understand what type of issue and repair that you’ll ultimately require, and below are some red flags of a faulty motor that you should be on the lookout for:

Weak Vent Airflow  

One of the most common warning signs of a faulty blower motor is when less air exits your home’s vents. It’s also possible that a clogged air filter could cause this symptom, so you should also double-check your filters when noticing weak airflow coming from your vents.

It’s also a good idea to check your system’s thermostat, particularly when you have a two-speed or variable-speed motor. If a low fan setting isn’t causing the issue, then it’s time to reach out to your local HVAC specialists and have them examine your system’s motor.

Little To No Airflow

Faulty thermostats, relays, and capacitors can contribute to little or no airflow coming from your system, but it’s important to understand how this symptom generally indicates pretty serious mechanical problems.

It’s likely that you’ll also experience other troubling symptoms when your lack of airflow is connected to your fan motor, and these HVAC repairs are always complex and require professional assistance.

Loud & Unusual HVAC Sounds

Failing blower motors will usually make a lot of strange sounds, which often come in the form of squealing and screeching. This is particularly the case if your motor is experiencing worn-out bearings.

It’s also possible to hear banging or rattling sounds coming from your AC unit when certain motor components have become loose.

Unexpectedly High Energy Bills

When your energy bills are rising unexpectedly, it’s likely connected to an abnormal increase in your property’s electricity consumption. When your home is suffering from an electrical drain, it could be a failing blower motor that’s creating more systematic resistance.

So, if your blower motor is failing, it’ll ultimately cause your home to consume more energy—which will take a hit on your wallet!

Consistent System Overheating

Overheating is another hazardous warning sign associated with a struggling blower motor. This could also be associated with burning smells emanating from your home’s vents.

This, of course, is a very serious situation that’ll require you to immediately turn your system off and schedule a service call with the Beehive Team!

Tripping Circuit Breakers

Your AC system will cause consistent circuit breaker trips when the unit is using up too much power. This type of scenario is sometimes caused by blower motor failures, but it can also be connected to compressor and condensing unit fan issues as well.

This type of repair job will require a professional HVAC technician to properly troubleshoot and fix.
