The capacitor is one of the hardest-working parts in your AC. It stores and releases the jolt of electricity that gets your compressor and fan motors going, and because it works that hard every cycle, it’s also one of the most likely parts to fail. Here are eight signs yours might be going bad.
8 Signs of a Failing AC Capacitor
- Weak cooling, the AC runs but can’t keep the house cold
- The AC won’t turn on, or hums and clicks without starting
- The system shuts off on its own (short cycling)
- A humming or clicking noise from the outdoor unit
- Higher energy bills as the system strains to run
- Delayed start, the AC takes a while to kick on
- A visibly swollen or leaking capacitor in the outdoor unit
- The AC suddenly stops working entirely
Why Capacitors Fail
Age and heat are the main reasons. Capacitors naturally wear out over time, and Spokane’s hot summers, when your AC runs hardest, speed up the process. Power surges can also take one out.
Can You Replace It Yourself?
It’s a small, inexpensive part, but a capacitor holds a dangerous high-voltage charge even after the power’s off. This is one to leave to a licensed tech, who’ll also confirm the capacitor is the real problem and not a symptom of something bigger.
Get It Fixed Fast and Safely
