A failing capacitor often leads to your AC running poorly or not at all, which can leave you without cooling when you need it most.

With proper maintenance, most capacitors last 10-15 years, but factors like heat exposure and power fluctuations can cause early failure.

If your AC system is over 10 years old or has frequent capacitor issues, you …
