What is Capacitor?
A capacitor is a small electrical component that stores and releases the jolt of energy the compressor and fan motors need to start and keep running. When one weakens, motors hum without starting, start intermittently, or the outdoor unit runs while the fan doesn't spin.
Why it matters in Arizona
Capacitors are the most common summer failure we see in the Greater Phoenix area — 150°+ inside a sun-baked electrical panel steadily degrades them, and monsoon power blinks finish off the weak ones. The good news: they're one of the cheapest and fastest AC repairs.
