An air conditioning system uses several motors to operate. This is where most of the electrical power goes, and the reason you see an increase in your electric bills during the summer. The most powerful motor drives the compressor, the heart of the AC. There are several other motors in operation, such as the blower fan motor responsible for the circulation of air through a house and moving warm air across the evaporator coil to cool it down.
Motors have a finite service life. They will eventually wear down and need to be replaced. With proper care, you can help keep the motors in your AC running until it’s time to have the entire air conditioner replaced (usually in the 10 to 15-year range). But motors may run down earlier.
We’re going to look at signs you have motors in trouble and the ways you can help keep your AC’s motors running with proper maintenance and air conditioning system repair in Loganville, GA.
Signs of a Burnt-Out Motor
Here are a few symptoms that might indicate a motor in your AC is in jeopardy:
- Strange noises: If you hear grinding, screeching, or rattling sounds coming from your air conditioner, it’s a strong indication that a motor is struggling. These noises often occur because of worn bearings, lack of lubrication, or internal components that have come loose.
- Unusual odors: A burning smell coming from the vents or the unit itself is a serious warning. This could mean the motor is overheating, and it’s burning through its insulation. If you notice this, shut off the AC immediately and contact professionals.
- Reduced airflow: When the blower motor begins to fail, it can’t push air as effectively through the ducts. You might notice weaker airflow from your vents, which can also cause the AC to work harder and increase energy costs.
- AC won’t start: If you attempt to turn on your air conditioner and it doesn’t start, a burnt-out motor could be to blame. In some cases, the motor might struggle to start, resulting in a brief attempt to run followed by a shutdown.
Preventing Motor Burnout
- Schedule regular maintenance: Care for motors is a key part of professional maintenance. During spring maintenance, technicians will clean and lubricate the motors as necessary, helping to reduce strain that can lead to burnout.
- Regularly change filters: A clogged air filter will restrict airflow, causing the blower motor to work harder than necessary. Make it a habit to check and replace the air filters every 1 to 3 months.
- Get repairs done promptly: If you notice any of the warning signs mentioned above, don’t wait to call experts. Early intervention can prevent minor issues from escalating into major, expensive repairs.
