Common Causes
- The AC drawing too much current from a failing capacitor or compressor
- A short circuit in the unit's wiring
- An undersized or aging breaker
- The outdoor unit's contactor sticking
- General electrical wear, especially in older homes
What You Can Safely Check
- You can reset the breaker one time and see if the system runs normally afterward
When to Call NILOV
- The breaker trips more than once — do not keep resetting it repeatedly, as that can be a fire risk
- You are unsure whether the panel itself is original to an older home
- The breaker trips as soon as the AC starts, every time
