An AC capacitor, also known as a run capacitor, is an essential component in an air conditioning system. Its primary function is to store electrical energy and release it when the AC system requires additional power to start or run. AC capacitors come in different sizes and capacitance values, which determine the amount of energy they can store and release.

Capacitors in air conditioning systems are subject to a lot of stress and wear and tear, and may eventually fail over time. When a capacitor fails, it can cause the air conditioner to malfunction or not work at all. Therefore, it is important to have a high-quality and reliable AC capacitor in your air conditioning system to ensure it operates efficiently and effectively. Regular maintenance and inspection of the capacitor can also help prevent any potential issues and prolong its lifespan.
