SUPCO SPP6 Relay/Capacitor Hard Start Kit with 500% Increase Starting Torque

This was a 10 min install, but you need to savvy and comfortable working on electrical items, especially capacitors. There are You Tube videos that are constructive. After opening the nearby circuit breaker, opening up the electrical cover, grounding out the capacitor(s), and mounting/connecting the Hard Start kit, the kit performed as advertised. The AC compressor started up more easily and isn’t as loud at startup. This particular HS kit has an integrated Relay to disconnect its internal capacitor to prevent damage to the compressor motor after startup. Other comparable professional two wire or three wire HS kits cost about $150. My AC vendor offered to install their HS kit for $389,

Works very well and easy to install!

Received and installed in half an hour. Brought my seized AC compressor back to life. Reasonable priced.

I recently bought a motorhome with a 2500 watt generator. The previous owner did not have AC on it so it would fit in his garage (nine foot door). When rv dealer quoted me $1400 to install a new name AC, I elected to buy a 'basic' brand name Dometic 13,500 btu AC for $650. It was helpful that the RV was already wired and cut for the unit but the issue was whether the small gen would even run it. Many others had said it was really 'iffy' without installing a hard start kit. So I ordered and added this kit before I even put the new AC on the roof.Payoff - as soon as I hooked up the wiring, I fired up the gen let it run a few minutes and turned on the AC. Gen took it with only a typical added-load groan lasting a second or so.- Note: Lots of people complain that this 'start function' kit should be included from the factory. I believe the reason it is not is due to the likelihood that the relay in the kit will fail before anything else in the unit. I understand the electrical aspects and I'm pretty sure these will fail at n hours and long before anything else does.- Stars. Gave only 4 because it IS likely to fail at some point and because the better version - SPP6 E - is not designed to work reliably with 120 volt systems.

Good quality.

I bought this a year ago to keep as a spare and recently since I was cleaning our 2.5 ton Goodman condenser I decided to just install it since everything was taken apart already. It's a simple install, just bolt the CAP to the unit next to the existing one, and then for our unit, connect it to the red and yellow terminals on the existing CAP.After reassembly, the first thing I noticed is that the condenser kicks on instantly now, before it would have a ramp-up of 15-20 seconds where it would slowly start up before getting to full speed. Now, that happens immediately. Highly recommend installing one of these.

Good quality and price.Does the job and corks for all type of heat pumps single stage .

Fixed labored starts of the compressor. Sometimes just buzzing without starting at. Instant starts now.
