Is it normal for my AC to make noise when it starts?

A single click when the system starts or stops is normal — it's the relay switching. Squealing, banging, hissing, or continuous clicking are not normal and require a technician's inspection.

What does a hissing AC mean?

Hissing usually indicates a refrigerant leak. Refrigerant leaks reduce cooling efficiency, can damage the compressor, and are EPA-regulated — they must be repaired by a licensed technician. Call Bradford for same-day service.

My AC is rattling — should I be worried?

Rattling can be as simple as a loose panel screw or debris in the condenser. Check the outdoor unit for leaves or twigs first. If the rattling is internal or doesn't stop after clearing debris, call Bradford to inspect the blower assembly.

6 AC NOISES — WHAT THEY MEAN & WHAT TO DO

Use this guide to identify your AC noise and decide whether to call now or schedule service.

BANGING OR CLANKING

High Severity

Cause: Loose or broken part inside the compressor or blower assembly — a connecting rod, piston pin, or crankshaft.

Shut off the AC immediately and call Bradford. Running a system with a loose internal part causes compressor failure.

SQUEALING OR SCREECHING

Medium Severity

Cause: Worn fan belt (older systems) or failing motor bearings in the blower or condenser fan motor.

Schedule service within 24–48 hours. The belt or bearing can be replaced before it causes motor failure.

RATTLING

Low–Medium Severity

Cause: Loose panels, screws, or debris (leaves, twigs) in the outdoor condenser unit. Can also be a loose blower wheel.

Check for debris in the condenser. If the rattling is internal, call Bradford to inspect the blower assembly.

CLICKING AT STARTUP/SHUTDOWN

Normal Severity

Cause: A single click at startup and shutdown is normal — it's the relay switching. Rapid or continuous clicking indicates a failing relay or capacitor.

Continuous clicking = call Bradford same day. The capacitor or contactor may be failing.

HISSING OR BUBBLING

High Severity

Cause: Hissing usually indicates a refrigerant leak. Bubbling or gurgling can mean refrigerant is low or there's air in the refrigerant lines.

Call Bradford immediately. Refrigerant leaks are EPA-regulated and require a licensed technician to repair and recharge.

GURGLING NEAR INDOOR UNIT

Medium Severity

Cause: A clogged or slow condensate drain line. The gurgling is air bubbles passing through standing water in the drain pan or line.

Check the drain pan for standing water. If full, call Bradford for same-day drain line clearing to prevent overflow damage.

WHY AC NOISE ISSUES ARE URGENT IN GLENDALE

In Glendale's extreme summer heat, your AC runs 12–16 hours a day from May through September. That continuous operation puts enormous stress on every moving part — compressor, fan motors, belts, and bearings. A noise that might be minor in a cooler climate can escalate quickly when your system never gets a break.
