What is a Hard Start Kit?

A hard start kit is an electrical device designed to assist air conditioners in starting up more easily, especially in situations where there may be low voltage or other voltage-related issues. It provides an additional jolt of power to the compressor, helping it overcome the initial resistance and start running smoothly.

The primary component of a hard start kit is a start capacitor, which stores and delivers an extra surge of energy to the compressor during startup. This boost of power helps the compressor overcome the high starting torque required to get the unit running. In addition to the start capacitor, a hard start kit may also include a potential relay or a current relay, depending on the specific application.

Hard start kits are particularly beneficial for older air conditioning units or in situations where the power supply may be inadequate, such as during power outages or in areas with unstable voltage. They provide a solution to the common problem of “hard starting,” which often occurs when the compressor struggles to start due to insufficient voltage or aging components.

By using a hard start kit, you can significantly reduce the strain on your air conditioner’s compressor during startup. This can help extend the lifespan of the unit, prevent premature wear and tear, and improve overall performance.

It’s worth mentioning that hard start kits are commonly used for air conditioning systems, but they can also be utilized for other types of equipment, such as refrigeration units and heat pumps.

Now that we understand the purpose and function of a hard start kit, let’s take a closer look at how it actually works to enhance the performance of your air conditioning system.

How Does a Hard Start Kit Work?

A hard start kit works by providing an additional surge of power to the compressor of an air conditioning unit during startup. This extra boost of energy helps the compressor overcome the initial resistance and start running smoothly, even in situations where there may be low voltage or other voltage-related issues.

At the heart of a hard start kit is the start capacitor. This capacitor is connected in parallel with the run capacitor of the air conditioner’s compressor motor. When the power is supplied to the system, the start capacitor releases the energy it has stored, providing a temporary increase in voltage to the compressor. This surge of power helps the compressor overcome the high starting torque required to get the unit up and running.

In addition to the start capacitor, a hard start kit may include a potential relay or a current relay. These relays play a crucial role in the operation of the hard start kit. The potential relay senses when the motor has reached a certain speed and switches the start circuit out of the system. This allows the run capacitor to take over and continue to provide the necessary power to the motor.

The current relay, on the other hand, ensures that the hard start kit is only activated during startup and does not interfere with the normal operation of the air conditioner. It monitors the flow of current and opens the start capacitor circuit once the motor reaches a certain current level.

By providing an extra jolt of power during startup, a hard start kit reduces the strain on the compressor and other components of the air conditioning system. It helps overcome voltage-related issues, such as low voltage or voltage drops, that can hinder the proper operation of the unit. This, in turn, leads to smoother startups, improved efficiency, and increased overall performance.

It’s important to note that a hard start kit is not a universal solution for all air conditioning problems. If you’re experiencing issues with your system, it’s best to consult with a qualified HVAC technician who can diagnose the problem and determine if a hard start kit is the right solution for your specific situation.
