Woman Checking Temperature Air Conditioning

Air conditioner sounds should blend into the background, becoming white noise in your Kilgore, Texas, home. However, unusual clanks, squeals and bangs could indicate a problem with your HVAC system, warranting a call to a service technician.

Rattling or Clanking

Loud clanking or rattling sounds typically indicate an issue with the motor or blower assembly. Oftentimes, there’s a loose component somewhere in the system. Because loose parts can disconnect completely, it’s important to have the problem checked before you’re faced with more expensive repairs. If you hear these sounds when the blower is on, turn off the system and schedule an HVAC appointment immediately.


A distinctive thwapping noise occurs when something is stuck between the blower blades. Think of it as the sound playing cards make when flapping against bicycle spokes. In most cases, thwapping noises aren’t critical, because there’s likely debris inside the housing. But the resistance can wear out the motor over time if you don’t clean it.


Blower motors make squealing noises when there’s a bad belt or problems with the motor bearing. Fortunately, belts are a common and inexpensive repair. But you must replace them before they break; otherwise, the blower can’t turn. Your service technician might add lubricant as needed to solve screeching or squealing sounds not involving the belt.


Clicking is normal when you turn your air conditioner on and off. But if you hear repeated clicking noises, you could have a defective relay.

Other issues causing repeated clicking sounds involve the outside compressor or electrical controls. Your HVAC service technician will investigate the system thoroughly to identify the cause before coming up with a solution.


A low hum or whistle is generally a minor concern. In most cases, humming indicates a damaged or loose seal. This is a quick fix for any licensed HVAC contractor.

Prevent unusual sounds from plaguing your system by scheduling an annual air conditioning service. Call JD’s A/C at (903) 759-7483 to set up an appointment.
