An AC unit is a useful appliance in your home, particularly when temperatures begin to rise. It is important to regularly maintain your air conditioner unit to ensure that it doesn’t break down when it is needed the most. In case your AC unit is acting unusually or not providing cool air, then you should contact an HVAC professional to check where the problem is and have it fixed as soon as possible.

There are many factors that can cause an air conditioning unit to malfunction. Some of them can be fixed easily while others may require some parts–or even the whole system–to be replaced. The blower motor is one of the most important components in an HVAC unit. It must be in good condition to ensure your air conditioner is operating efficiently.

There are two major types of AC motors: the single-speed motor and the variable-speed motor. When it’s on, a single-speed motor blows air at one speed and to full capacity. It will turn on and off based on the settings of the thermostat. A variable-speed motor runs at more than one speed, allowing for more temperature control and even air distribution throughout the home.

Signs That Your AC Motor Needs to Be Replaced

If you start experiencing issues with your AC system, it could be a problem with the blower motor. Just like any part of the air conditioning unit, an AC motor becomes more vulnerable to mechanical issues as time goes by.

While repairing the motor can help improve things, the best option would be to replace it as soon as you start having issues with it. Contact an HVAC technician from Element Air LLC to replace your blower once you start seeing the following signs.

No Airflow

A total lack of airflow is likely a sign that your HVAC motor has become inoperable. The only solution to this kind of problem is replacing the motor. However, the lack of airflow could also be a result of a bad battery, a faulty thermostat, or a fan control issue. The person who’s most qualified to determine the source of the problem is an HVAC specialist from Element Air LLC, so give us a call if your system stops blowing cool air.

Weak Airflow

Another one of the first signs of a faulty blower motor is weak airflow, which means that the blower is experiencing difficulty pushing air through the ducts to attain the right temperatures. This could be due to a bad capacitor or dust and dirt build-up in the motor. It would be a good idea to have a heating a cooling expert find out if the blower motor is the cause of weak airflow.

Strange Sounds

Unusual sounds coming from your air conditioning unit may be a sign that something is wrong with the blower motor. Screeching or squealing noises is an indication the blower motor has a damaged or broken belt.

This problem can be fixed by lubricating the bearings or replacing the belt. In case the motor is producing a lot of clanking, rattling or banging sound, then there could be a broken or loose part somewhere.

Unusually High Energy Bills

An AC motor uses a lot of energy. An old, dirty, or damaged motor must overwork to generate and circulate conditioned air throughout your home. This uses more energy. If you’re using an AC unit with a compromised motor, replacing it would be the best way to save money on your energy bills and stop taxing your system.


This is another sign that you need to replace your AC motor. Grime and dirt on the motor may be preventing it from venting, causing heat to build up over time. Additionally, an old AC unit can easily overheat because of the extra work it has to do to regulate temperatures in your home.
