Your cart is empty.This product has been developed specifically to soft start large single phase compressors and motors. It provides a dramatic reduction in the starting current but still provides full start torque. Fully self-contained in a conveniently small, double insulated and flame retardant enclosure.

Application: 2 whole house heat pumps. one is 3.5 tonnes and other is 2.0. I wanted to drop the startup amps to run a smaller generator in case of power outage. And to prolong the life of the compressors.Pros:- easy to install-small can/must be mounted in covered area with other wiring/electronicscons:- possible loose connections (unlike other prewired units), they give you torque settings.- must mount under the cover ( might be an issue with smaller units) though I had no problem fitting it adjacent to factory electronics.Conclusion:Pre/post 54 amps down to 11.1amps for the 3.5 tonnes (81% reduction)54.8amps down to 5.1amps for the 2 ton unit (90%reduction)Amazing results. I had my reservations about the install as the wires did not come preinstalled to the unit. It was so simple. The first one took 30min as I was double checking the wiring diagram. Second one under 10 min as soon I understood the general layout of different compressor units. Unsure of longevity of units, but so far very pleased for price. I tried another unit from another company and couldnt get it to run.

I want to be able to run our 4 ton ACs off of generator power if needed, which is why I purchased these soft start kits. I didn't want anything fancy that required a phone app like some of the other brands, and just wanted something simple that worked. These state that they reduce the startup current by up to 50%, and I tested and saw about that. The photos I provided show close to 128A startup prior to installing the unit and then 67.5A after installing the unit. The second measurement was the first startup attempt after installing the unit, and the unit does say it could take up to 6 starts to optimize. So it is possible the inrush amps go down once it is fully optimized. I'll test that out later and update this review if I get lower readings. Regardless, I'm completely satisfied as it does what it says!Install wasn't too difficult, but it took me a little bit to read the AC schematic to figure out which wires to use. Once I figured that out install went smoothly. The unit comes with all necessary wires. The only thing I added was a crimp on loop for the compressor run wire.

I had no idea these existed, our main ac unit would dim the lights when it cycled on, on normal power and the generator would really work hard when it cycled on. This device took my Ac guy 15 minutes to install for me, and it just plain works. The ac unit kicks on and off and not a light flickers or dims, on either power source. I don’t understand why these aren’t installed on new installations. If you look into them you can see the surge power is greatly reduced by using this item. Buy one for each unit you have you won’t regret it.

My 4 ton Rheem system is from 2011. It's young enough to have variable speed ECM fan motors. It has a control board instead of simple contactor. I got the thing wired up after a lot of head scratching and a little guesswork. When I switched the 240v power back on to the condenser unit for the first time, I heard a pop which I think was the brains of the Genteq ECM fan motor shorting out.Currently the compressor will start but condenser fan will not. I tried giving it a push, nothing. Currently figuring out my next move. I'm pretty sure I need to replace the fan motor. I requested support vis email on the website a couple weeks ago but no response.Make sure you know what you are getting into with this product. The instructions say to email tech support for help wiring if you have a control board. Seems like they could have done a bit more field testing with this product with different systems and made some better instructions before putting it out.

So I was a bit intimidated about installing myself, but figures I’d try. It was easier than I expected and works great. The unit used make a pretty harsh clunk when it came on and now it just whirs a few seconds and then it’s up speed, doing it’s thing, Sounds so much healthier. My HVAC techs recommended a similar product but I self-installed to save money. I expect less wear and tear on the unit and while I haven’t tested the initial amp draw yet, I know it’s greatly improved just by the sound.

So I had some trouble hooking this up but the device came with a card that said to call Bob with the for any install issues. To my surprise it was actually Bob. He guy knew what he was doing and talked me through all the connections because the instructions were confusing to me. The device is well built and seems to do what it says but just wouldn’t work for me. It did drop the inrush of my compressor from 62ish amps to 39ish amps which is pretty good I think. On utility power this thing works great but on generator it will not start the compressor. My generator is a Westinghouse 10,500tfc that puts out 13,500 watts peak on gasoline and it started and ran the AC compresor without the soft start. Bob said if it worked on utility power it should’ve worked on the generator so I’m just returning it. They don’t pay for return shipping so keep that in mind. I give it four stars because it could just be an issue with my old AC unit or the soft start just doesn’t like the quality of power my generator puts out. I was really hoping this would allow me to start my AC with my generator running on natural gas. All that being said there are more success stories with this device than failures.
