An AC capacitor is the component that sends electricity into your heating and cooling system to power its operation. It normally provides an initial jolt of electricity upon startup, but then, it reduces its electrical output once the AC system is up and running. Without the capacitor for AC unit, your system could not start or continue running, so its performance is needed throughout the entire cycle of your system. Unfortunately, AC systems require a strong boost of electricity to work effectively, so your AC system will require a capacitor instead of simply plugging into your home or commercial electrical grid, and even more unfortunately, a failing capacitor is one of the most common reasons that your AC system might no longer be performing as it should.
As with nearly all electrical components, your capacitor may simply overheat and wear out over time. Other common causes for capacitor failure include power surges, lightning strikes, and fluctuations in the power grid.
While you may be tempted, don't ever attempt to change your capacitor. While it may appear similar to a battery, it is NOT a battery. Instead, it is a very high-voltage device that can cause serious injury if not handled properly - even if your power is off. That's why it is imperative to always hire a professional AC technician to complete any capacitor testing, repairs, or replacements.
