Why Is My Chambersburg, PA Air Conditioner Making Loud Noises?

July 31, 2020

Every heating, ventilation and air conditioning system makes sounds associated with phases of operation. You may hear whirring as the unit starts up, air blowing through vents or a background hum when the system is on. However, unusual sounds can indicate a serious problem. If you hear loud noises in your Chambersburg, Pennsylvania, HVAC system, call your local air conditioning repair company to investigate.

Squealing, Screeching or Screaming

Squealing is common for some units on startup. However, the sound should not continue during operation. If squealing continues, it may signal a bad belt or worn motor bearings. If you hear a high-pitched scream, shut the unit down immediately. This sound may be due to leaking refrigerant or too much pressure in the compressor. Call for AC repair service immediately.

Banging or Clanging

Banging often indicates a loose part inside the compressor or a problem with the blower. If the problem is inside the compressor, have the unit checked as soon as possible to avoid further damage. If too much damage occurs, repairs may not be cost-effective, requiring a new unit.

Clanging can be caused by a fan blade hitting the housing, an unbalanced blower or a loose motor mount. Attending to repairs quickly reduces the potential for major damage.

Clicking or Tapping

Take time to listen to your system as it turns on, operates and shuts down. When you are familiar with normal sounds, you will be alerted to unusual sounds. Clicking is often heard as a system starts up or shuts down. However, if clicking continues throughout the cooling cycle, it may indicate a fault in the electrical system.
