How to Know When Your AC Capacitor Is Failing – Signs, Causes & Quick Fixes

⚙️ What Does an AC Capacitor Do?

Your air conditioner relies on a small but mighty part called the capacitor. It stores and releases electrical energy to power the motors — mainly the compressor and fan. Without a working capacitor, your system can't start or run efficiently.

🚨 Signs Your Capacitor Might Be Failing

• AC won’t turn on
• Warm air blowing instead of cold
• Unusual humming or clicking sounds
• AC starts but shuts off quickly
• Rising energy bills

If you’re experiencing any of these symptoms, a failing capacitor may be the cause.

⚠️ Common Causes of Capacitor Failure

• Age and wear over time
• Power surges or lightning strikes
• Overheating from clogged filters or dirty coils
• Poor installation or low-quality parts

✅ What to Do If Your Capacitor Fails

Capacitors can store dangerous voltage — so never attempt a DIY fix. Call a licensed HVAC technician to inspect and replace it safely. Acting fast prevents more serious damage to your compressor or system.

🛡️ How to Prevent Future Issues

The best defense is regular maintenance. Annual tune-ups check all electrical components, clean coils, and ensure every part runs smoothly — including your capacitor.
