Like any other mechanical device, AC motors have a limited life span and eventually need replacement. However, several factors can affect how long an AC motor will last, so it’s vital to recognize signs indicating your need for a replacement.

Age of the Unit

One of the most significant factors in determining how long an AC motor will last is the age of the unit. Generally, AC motors in newer units will last longer than those in older units. This is because manufacturers have improved AC motor technology over time, resulting in more durable and longer-lasting products.


Another factor that can affect an AC motor’s life span is usage. Units used more frequently will typically need their engines replaced sooner than the ones that get used less often. This replacement occurs because frequent usage puts more wear and tear on the motor, which causes it to break down sooner.

A Noisy Unit

If your air conditioner makes strange noises, it could be a sign that the motor is starting to fail. Typical sounds that indicate a problem with the AC motor include grinding, squealing, and humming.

Decreased Efficiency

If your air conditioner isn’t cooling as well as it used to, it could be because the motor is losing power. This loss of strength can cause the unit to work harder, which uses more energy and increases your utility bills.

Burnt Smell From the Vents

A burnt smell from the vents is another sign that the AC motor needs replacement. This smell indicates that the motor is overheating, thus damaging the unit and shortening its life span.
