Is Your AC System Gossiping? 👂 What Those Weird Noises Really Mean!

Here’s a guide to what those common AC noises might be trying to tell you:
Your air conditioner should keep you cool—not keep you guessing. If your system is making strange noises, it’s trying to tell you something. At Coastal Comfort Air Conditioning, we help South Florida residents decode those sounds and fix them fast.
Buzzing
Could mean electrical issues, a loose part, or debris near the outdoor unit. Call for AC repair before it becomes a safety risk.

Hissing or Whistling
Usually points to a refrigerant leak or duct issue. Both need attention from an experienced HVAC technician.

Clicking
This can be normal at startup but ongoing clicking might mean a failing thermostat or relay issue.

Banging or Clanking
Loud, metal-on-metal sounds can signal broken parts inside the compressor or blower. Stop running the system and call right away.

Squealing
A high-pitched squeal could mean a worn belt or motor bearing. These problems won’t go away on their own—and they usually get worse.

At Coastal Comfort Air Conditioning, we diagnose and fix weird noises. Our licensed techs offer everything from simple repairs to full AC installations, using the latest tools and parts to keep your system running right.
