How to check a hard start kit
- Check whether the potential relay is properly installed according to instructions.
- Ensure your capacitor is in good shape.
- If there’s nothing wrong with the connection and there’s not a reduction in the flow of current, proceed to the next step.
- Pick one of the wires of the hard start capacitor and put a current meter on it. ...
How does a hard start kit work?
A hard start kit is a start capacitor. It’s a device used to resolve an air conditioning system problem called hard starting. To understand how a hard start kit works, first you should have an idea how a compressor works during AC startup. Essentially, the compressor is the heart of your air conditioner. It powers the AC.
Do I need a hard start kit for my AC?
A hard start kit on a single-stage air conditioner or a heat pump can reduce the strain on your system to start up by as much as 50%. Having a hard start kit can also prolong the life of your system, so we recommend it for every new single-stage air conditioner or heat pump.
What is the difference between a hard start kit and PTC kits?
PTC kits are considered more convenient because of their 2-wire feature, which helps with easy installation. With the help of electro-motive force, the mechanical potential relay hard start kit takes the capacitor out of the circuit once the compressor is at 80% of its capacity.
How do I know if my air conditioner is hard starting?
If you hear a stutter or clicking noise when you turn on your AC, and your AC doesn’t stay on for long, then those are signs your air conditioner is hard starting. Contact a Phoenix AC professional if your air conditioner/heat pump is hard starting. It could cause serious damage to your cooling system, so you should get it fixed ASAP.
Can a hard start kit fail?
With the large “boost” of capacitance from the Hard-Start Kit, compressor failure WILL occur after an extended time running without the motor-run capacitor, accompanied by the repeated “hammering” the motor takes from “high-boost” over-capacitance starts.
How do you test a hard start relay?
Disconnect the voltage source from the circuit and remove the relay from the circuit. First check the relay's coil by placing the leads of the ohmmeter across the 2 and 5 terminals of the relay. If the ohmmeter reads a high resistance (approximately 3,000 to 18,000 ohms) the coil of the relay is electrically OK.
How long will a hard start kit last?
Most off the shelf kits are worthless and die in the first year. If you need one however ,using the one designed by the manufacturer of the equipment is highly reccomended.It will at least last more than a year.
Can a hard start kit damage a compressor?
The pits could cause great harm to the compressor motor during the inrush amperage mode at start up. During the inrush amperage mode at startup, the amperage is near seven times the running amperage which could be over 100 amps at times!
How do you know if starter relay is bad?
5. Symptoms of starter relay failure The vehicle cannot be started. The failure of a car to start is one of the most obvious signs of a car breakdown. ... The start relay remains open after the engine is started. ... The starter makes a clicking sound. ... The vehicle starts intermittently.
How do you check if starter relay is working?
Using your multimeter, place probes on both the ground lead and ignition circuit terminal. If the reading is more than 5 Ohms, your starter relay needs replacement. You can also use a wire jumper to check for resistance.
When should I replace my hard start kit?
Hard starting may also be a sign that the air conditioner is worn down and ready for replacement. This can easily be discovered when you regular AC maintenance check-up. Sometimes replacing a hard starting air conditioning system is more cost-effective than getting it repaired over and over.
How much should a hard start kit cost?
One of the most common motivations for installing a hard start kit is preserving the compressor of an AC unit. A compressor can cost anywhere from $1,200 to $2,500 to replace, whereas it typically costs less than $400 to install a hard start kit.
When should a hard start kit be installed?

So what this hard start kit does for the compressor on an AC is.
Does a hard start kit reduce inrush current?
Hard start kits added to a new compressor greatly reduce this strain on the compressor windings while possibly extending the life of the compressor. This reduction in start-up inrush current may also reduce operational cost as well as stopping light flicker.
Is a hard start kit the same as a soft start?
As you can see, hard starters and soft starters are two completely different concepts. Hard starts aim to make the inrush of current as large as possible while the soft start lowers the inrush of current as much as possible.
How do I test a relay with a multimeter?
Grab a multimeter and set it to Ohms. Touch the leads across the electromagnet coil pins and measure resistance. Anywhere from 50-120 ohms is OK. Out of range or open means a bad electromagnet coil winding and time for a new relay.
How do you test a car relay with a multimeter?
Take the leads of the multimeter and connect them across the coil terminals of the relay. For a normal coil, the multimeter should read anywhere between 40Ω to 120Ω. If the coil is damaged i.e., it is open, the meter shows out of range and you have to replace the relay.

What is a hard start kit?
A hard start kit is an energy-storing capacitor that helps your AC start when it’s struggling to turn on. As their name suggests, hard start kits help solve a problem called hard starting, which is when an AC struggles to turn on and then shuts off abruptly after a short while. If you hear a stutter or clicking noise when you turn on your AC, ...
How efficient is a hard start kit?
In fact, with a hard start kit, the electrical efficiency of the startup process is as high as 98%, compared to an efficiency of only 50% without one. This efficiency reduces heat and wear on the compressor and other important AC components.

Do AC units have a hard start kit?
In the past, most single-phase ACs came from the manufacturer with built-in hard start devices, but many newer AC models don’t include a hard start kit. If your air conditioner doesn’t have a built-in hard start kit (your technician will let you know), you should consider having an AC professional install one.
Can a hard start kit fix a compressor?
However, if your compressor is near the end of its life, then a hard start kit may prolong its life for a short time, but shouldn’t be viewed as a long-term fix.

What causes hard starting?
There are several reasons why an air conditioner experiences a hard starting problem. Knowing them may help you find the solution even before you call an expert in air conditioners.
Why is my air conditioner hard to start?
Worn down compressor motor due to loss of lubrication is another cause of hard starting. Without proper or enough lubrication, the compressor tightens up and has difficulty moving. Hard starting may also be a sign that the air conditioner is worn down and ready for replacement.
What is a PTC kit?
The PTC (positive temperature coefficient) is a 2-wire hard start kit that uses a ceramic component to remove the capacitor out of the circuit. As the PTC component heats up in less than a second, the capacitor is taken out. PTC kits are considered more convenient because of their 2-wire feature, which helps with easy installation.
What is a mechanical potential relay hard start kit?
