A customer was concerned because their lights would dim every time their air conditioner started up, a sign the compressor was struggling. This can cause long-term damage to the system's most expensive component. I solved this problem by installing a hard start kit on their outdoor unit. This kit provides an extra electrical boost on startup, allowing the compressor to turn on smoothly and quickly without straining the home's electrical system. The lights no longer dim, and the AC starts without hesitation.
