Understanding a Hard Start Kit for Your AC System

Have you ever experienced a delay in starting or a loud buzzing sound from your air conditioning unit? Did you know that these are common signs that your AC system needs a hard start kit? If you're unfamiliar with this device, let's get into the details.

What is a hard start kit? 


A hard start kit is an electrical device that helps your air conditioning unit start up quickly and efficiently.

What does a hard start kit contain?

It contains a capacitor and a potential relay that work together to provide an extra boost of power to your compressor.

The capacitor stores energy and releases it when your AC needs it the most. The potential relay, on the other hand, senses when there is enough power to start the compressor and then disconnects from the capacitor.

Reasons why your AC system may need a hard start kit


There are several reasons why your AC system may need a hard start kit.

One common reason is due to age. As AC units get older, they tend to experience wear and tear, which can cause the compressor to have difficulty starting up.

Another reason is due to power fluctuations. If your home experiences frequent power fluctuations, it can cause your air conditioning unit to struggle to start up.


Installing a hard start kit can help prolong the life of your air conditioning unit and save you money in the long run.

By reducing the strain on your compressor, it can prevent premature failure and costly repairs or replacements. It can also improve the efficiency of your AC system, which means lower energy bills.


Keep in mind that not all AC units require a hard start kit. It's best to consult with a professional HVAC technician to determine if it's necessary for your specific system. They can also install the device for you, as well as ensure that it's properly calibrated to match your AC unit.


Understanding how a hard start kit works and why it's beneficial for your AC system is essential for every homeowner.

By consulting with a professional technician and installing this device, you can improve the performance and efficiency of your air conditioning unit while saving money in the long run.

Don't let a delay in starting or a loud buzzing sound from your AC unit go ignored. Invest in a hard start kit today and enjoy a cool, comfortable home all summer long.
