AC Capacitor: When It Should Be Replaced | Heatwave
When your air conditioner is on, your air conditioner capacitor is likely failing if you hear a loud buzzing sound. If your energy bills are unreasonably high, it could be due to the capacitor failing to control the current flow from the compressor to the blower, using more energy than usual. This can happen if the capacitor is of a low quality.
