Been using Kickstart for decades on multiple units. One failure during that time which was quickly replaced under Warranty. Uses a potential relay which is critical for safe and effective operation.

Purchased and installed in June 2023, Rectorseal hard start kit died in May 2024. Had to call AC tech out and even after replacing our capacitor, AC would not start with hard start kit attached. He had to disconnect it to get AC working. No problem, I'll get a replacement. Nope. Seller, Triad Global Resources, refused to replace, told me to contact manufacture. I contacted Rectorseal, they said contact Amazon, Amazon would not help, told me to dispute the charges on my card! Regardless, the seller should make good. They advertise the item with 3 year warranty and wouldn't help at all. Will never buy Rectorseal again, instead replacing withCPS 5-2-1 CSRU1 Compressor Saver

I'm not an electrician, but it was not hard to install. To maybe 10 minutes. I can tell the difference when the compressor kicks on. On the Gulf Coast our AC runs almost year around, so this should help with longevity of the unit.

My 15 year-old, 3 ton does the majority of work in our house because it cools the upstairs. Still ran well and didn't during compressor start, but Its contactor had worn down to barely any contact pads. It was time to do some PM on its electrical parts.First, replaced its dual-run caps with a US made AmRad (https://www.amazon.com/gp/product/B00GSU47TQ). A Lennox replacement contactor (https://www.amazon.com/gp/product/B00DZP2VN6) was a drop in replacement for the worn contactor. With known good contactor and run capacitor, it was ready to accept a start capacitor kit.I wanted to add a start capacitor to reduce startup current due to age of compressor and assist when running on whole house generator. PTC units were excluded due to their lower startup boost and inability to repeat without cool down. 5-2-1 three wire units were considered, but I was worried about how closely their potential relay would match the actual back EM voltage of my compressor. This Rectorseal T0-5 (1 to 3 ton) Kickstart, with two wire potential relay, was selected because it measures across a place with less back EMF voltage variance. That gave me more confidence that it would drop out at the correct time.Got a low cost clamp meter with INRUSH capability https://www.amazon.com/gp/product/B088WZJ1VQ to check results.Compressor is a 2005 Allegiance 14 American Standard 3 ton with spec LRA of 83 amps.Before connecting KS T05, it was pulling 101 amps inrush.After installing the Kickstart T0-5, inrush was 60 amps.Inrush went from above LRA spec to well below!EDIT: Added startup current waveforms captured on compressor common wire. Current probe and oscilloscope used to capture startup current after two preliminary start ups and 5 minutes waits between starts. The peak to peak currents drawn on common wire are nearly identical with and without Kickstart, but the time spent drawing that much current is much less with Kickstart installed. Compressor definitely comes up to speed much more quickly with starting capacitor.

Very ez install I have a 2 story house in Florida with 2 3ton ac units so I got this on hopes my it will help my generator will help keep the house cool for the next hurricane an I picked up 1 and installed it on my upstairs ac unit and it definitely see a difference with it starting compared to the one that doesn't have it ,,, so I ordered another one for the downstairs unitUpdate 5/13/20 : got another one to add to the downstairs ac unit noticed a difference right away. hopefully it'll help with the electric bill tooUpdate 5/19/20 : ordered a meter from amazon that has inrush feature and measured both of my AC units they were both at aprox 74 amps on start up with out the kickstarter and aprox 48 amps with the kick start which is pretty significant mostly because its lower amperage and for a much shorter duration ,, also noticed my running amps was only around 8 amps nothing to do with the kickstart just feel better about my 12kw generator being able to run most of the house w/ac

I have a Goodman 3 ton heat pump(only about 3 years old). There was no problems telling when the compressor kick in as the lights in the house would dim for half a second. I installed a 3 wire hard start kit and had no noticeable improvements. Purchased this unit (by the way very easy to install) and notice a significant difference. The heat pump is much quieter when starting and the lights in the house barely change. I don't need an amp meter to know it's working as I had hoped. I would recommend.

Kickstart hard start kits are easy to install, and they are very effective. I had an A/C unit that drew 31 A starting current. I installed a Kickstart TO-5, and the starting current dropped to 8 A. That right: From 31 A to 8 A. The TO-5 nearly cut the inrush current to 1/4. I'm a believer. I've installed Kickstarts on all three of my A/C. Lower inrush current and a faster start reduces starting heat in the compressor. It's also beneficial since I have a Generac whole-home generator that can't provide as many amps as my electric company.There are a lot of misconceptions about what a start/run capacitor does. Some people claim it stores energy like a battery and provides it for the start. That is FALSE. This is alternating current that reverses 60 Hz; you can't store AC. The purpose of a start/run capacitor is to shift the phase of the current fed to the offset armature windings that provide torque to get the armature spinning. The Kickstart significantly increases the capacitance (and phase shift) during the starting period. Once the compressor is up to speed, the Kickstart's relay removes it from the circuit.
