Why the AC Capacitor Matters
An AC capacitor stores electrical energy and delivers the extra boost needed to start and keep the compressor and fan motor running. Most outdoor condensers use either a dual-run capacitor or separate start and run capacitors.When this small component wears out, your entire cooling system can struggle to operate efficiently.
Signs Your Capacitor May Be Failing
- Outdoor AC unit hums but won't start
- Fan blades are not spinning
- Warm air comes from the vents
- System takes longer to cool
- AC shuts off unexpectedly
- Burning smell near the outdoor unit
- Visible bulging or leaking capacitor
