What is an AC Compressor Saver?
An AC compressor saver, also known as a hard start kit, is a small device that gets attached to the condensing unit of your air conditioning system. Its primary function is to assist the compressor during startup, reducing the initial surge of electrical current. By doing so, it lessens the load on the compressor, potentially extending its lifespan and saving energy.
Advantages of Using an AC Compressor Saver
Installing an AC compressor saver comes with several notable advantages that can make it a worthy addition to your air conditioning system. Here we will discuss each benefit in depth:
Energy Savings
One of the most immediate benefits you will notice is a reduction in your energy bill. Air conditioners use a significant amount of power during startup. The compressor saver reduces the initial electrical load by supplying a quick burst of energy. Over time, these energy savings can add up, helping to offset the cost of the device.
Extended Compressor Lifespan
When an AC compressor has to work hard to start, it undergoes significant stress. This stress can lead to increased wear and tear and ultimately reduce the lifespan of the compressor. By easing the startup process, a compressor saver can extend the life of your compressor by several years, saving you from expensive repairs or replacements.
Reduced Wear and Tear on Other Components
While the compressor is the primary component that benefits from a compressor saver, other parts of the AC unit also experience less stress during startup. Reduced stress on these components means a lower likelihood of mechanical failures, which in turn leads to fewer repair costs.
Are AC Compressor Savers Worth It?
The question of worthiness when it comes to installing an AC compressor saver is contingent on several factors. Here, we’ll go through these factors to help you make an informed decision.
Age of the AC Unit: Older AC units that lack modern energy-saving features are more likely to benefit from a compressor saver. Newer models may already include features that minimize startup energy, making an additional compressor saver less effective.
Frequency of Use: If you live in a hot climate where the AC unit is frequently used, the energy savings and reduced wear and tear can make a compressor saver a valuable investment.
Electricity Rates: High electricity rates can make the energy savings from a compressor saver more significant, potentially leading to a quicker return on investment.
Cost of the Device and Installation: The initial costs can vary. If you can install the device yourself, you’ll save on labor costs. However, if you require a professional, this will add to the initial investment. Weigh these costs against the potential benefits to gauge if the investment is worthwhile for you.
Warranty and Service: Some compressor savers come with warranties or service packages that can add value to your purchase. Make sure to read the fine print and understand what is covered.

How Does It Work?
The AC compressor saver is wired to your air conditioning unit’s electrical system. When you turn on the AC, instead of pulling a large amount of electricity to start, the compressor saver provides a quick jolt of energy. This reduces the time and energy the compressor needs to start. The device essentially stores power and releases it quickly, offering a more efficient startup for your air conditioning unit.
How to Install an AC Compressor Saver
Installation is generally simple, involving a few basic steps:
Turn off the power to your AC unit to ensure safety.
Locate the compressor’s electrical connections, usually found in a panel on the unit.
Connect the AC compressor saver according to the manufacturer’s instructions. This usually involves attaching two wires.
Secure the device to the AC unit’s frame using zip ties or screws.
Restore power and test the system to ensure it’s working as expected.
If you’re not comfortable with electrical work, it’s always best to hire a qualified technician.
