Air Conditioner Capacitors
When the capacitor isn''t working properly, your air conditioner has to work harder and run longer to cool your home, consuming more electricity in the process. This inefficient operation means your AC is using extra power to achieve the same level of cooling, which can cause a noticeable increase in your energy costs.

Explaining Capacitors and the Different Types | DigiKey
Though film capacitors are generally quite durable, they are susceptible to a few long-term wear mechanisms. Over time, the dielectric materials used weaken, become brittle, and experience degradation in their voltage withstanding capability, which eventually leads to a dielectric breakdown failure.
