5 Sounds Your AC Makes and What They Mean

Picture this: a Thursday at 8:42 a.m., you're two blocks east of Biscayne Blvd on NE 123rd St, and the TPMS light comes on.

And more importantly, when should you call Aventura HVAC Maintenance?

Why is my AC making strange noises?

AC systems are complex machines with many moving parts. When something goes wrong, these parts can create unusual noises that can be alarming. Understanding these sounds can help you diagnose the problem and decide whether to call a professional.

How do I know if my AC is making a loud humming noise?

A loud humming noise is often the first sign of a problem. This sound can be caused by a variety of issues, including a failing compressor, a loose fan blade, or a dirty or clogged air filter. If your AC is making a loud humming noise, it's important to address the issue promptly to prevent further damage.

What causes a rattling or grinding noise in my AC?

A rattling or grinding noise can indicate that there's something loose or worn out inside your AC unit. This could be a loose screw, a worn-out belt, or a damaged fan blade. If you hear this noise, it's crucial to have a professional inspect your AC unit to prevent further damage.

Why does my AC make a hissing sound?

A hissing sound is often a sign of a refrigerant leak. Refrigerant is the substance that cools your home, and if it's leaking, your AC won't be able to do its job effectively. If you hear a hissing sound, it's important to call a professional immediately to address the issue.

What causes a squealing or screeching noise in my AC?

Why does my AC make a clicking or popping noise?

A clicking or popping noise can indicate that there's something wrong with the electrical components of your AC unit. This could be a faulty capacitor, a damaged start relay, or a worn-out contactor. If you hear this noise, it's important to call a professional to address the issue promptly.
