If your AC unit has started making strange noises, don’t ignore it—those sounds are often warning signs of underlying issues. Whether it’s a buzzing, banging, or high-pitched squeal, each noise can indicate a specific problem. In this blog, we’ll break down common AC sounds, what they mean, and when you should call a professional specializing in Air Conditioning Jacksonville FL.
Common Air Conditioner Noises and Their Meanings
Banging or Clanking
This usually means a loose or broken part inside the compressor or fan. Over time, components can become unbalanced or detached, causing damage if not fixed quickly.
Possible cause: Loose fan blade, broken connecting rod, or compressor issues.
Solution: Schedule a professional inspection right away to avoid further damage.
Buzzing
Buzzing can be caused by several issues, including electrical problems, loose parts, or debris around the unit.
Possible cause: Faulty capacitor, loose wiring, dirty condenser coils.
Solution: Turn off the unit and call an HVAC technician for proper diagnosis.
Screeching or Squealing
This sound often indicates a worn-out belt or issues with the motor bearings. If ignored, it could lead to system failure.
Possible cause: Worn fan belt or motor malfunction.
Solution: Have your AC system inspected and lubricated by an HVAC professional.
Clicking
While clicking at startup and shutdown is normal, constant clicking can signal a failing thermostat or control issue.
Possible cause: Faulty relay or electrical control board.
Solution: Get it checked immediately to prevent breakdowns.
Hissing
A hissing sound could mean a refrigerant leak, which not only affects cooling but can be hazardous to your health.
Possible cause: Refrigerant line leak or internal valve issue.
Solution: Contact an expert in Air Conditioning Jacksonville FL to detect and fix the leak safely.
