Is Your AC Struggling to Start? It Could Be a Capacitor or Hard Start Issue

Is Your AC Struggling to Start? It Could Be a Capacitor or Hard Start Issue

When the Florida heat hits, a reliable air conditioner (AC) is essential. But what happens when your AC struggles to start or makes strange noises when it tries? The culprit could be a failing capacitor or hard start kit.

What’s a Capacitor, and What Does It Do?

An AC capacitor is a small cylindrical device that acts like a temporary storage unit for electricity. It provides a quick burst of power to the compressor motor, helping it overcome the initial hurdle of starting up.

What’s a Hard Start Kit, and What Does It Do?

A hard start kit is essentially an additional capacitor specifically designed to aid a struggling compressor motor during startup. It provides an even greater surge of power than a standard capacitor.

Signs of a Failing Capacitor or Hard Start Kit

Here are some signs that your AC’s capacitor or hard start kit might be failing:

  • Clicking or buzzing noises: When the AC tries to start, you might hear a clicking or buzzing sound coming from the outdoor unit. This could indicate the compressor struggling to overcome the initial startup.
  • Delayed startup: Your AC might take longer than usual to start, taking several attempts before finally kicking in.
  • Warm air instead of cool: If the compressor doesn’t start properly, your AC won’t be able to cool your home effectively. You might only feel warm air coming out of the vents.
  • Frequent tripping of the breaker: A failing capacitor or hard start kit can cause a surge in electrical current, tripping your circuit breaker.
