Review: Great product easy to install - Install it myself. There’s a couple of really good videos on YouTube on how to install it. It works absolutely great. Took my start up amperage till like 33. Don’t know what it was before and the app with the blue tooth connection works great as well definitely worth the money
Review: Quieter and smoother starts w/o spike in amps - Very easy to install if you're a little handy. Instructions are clear and they have your brand of compressor on their web page. Study the wiring diagram carefully and put some planning into where you will mount the device. Before installing, my Lenox compressor sounded like a truck with bad brakes sometimes when it started. Once I installed this, it became very quiet. With no spike in amps to start the compressor, I'm getting ready to run my HVAC off of whole-house battery backup, one step at a time. I was confused about how I could not access bluetooth when it was not running so I called customer support. A real person answered and explained to me that once the compressor stops running, the device is powered down and bluetooth is not available. This was terrific customer service!

### ⭐⭐⭐⭐⭐ Super easy install, quality product with good directions
*by M***I on July 14, 2026*

I bought this soft start kit for my sons A/C system. I watched many videos online and looked for the best one. When I found a video of a guy putting this exact one on his A/C it looked to easy and appeared to work great. So, I tried it out. My A/C was a different brand than what he installed it on. However, it was almost identical in the installation procedure and was by far the easiest one I saw. I think the overall installation was about 15 minutes. There were no special tools needed and it mounted behind the cover plate just fine. We started it up and measured the amps after installation and it was drastically reduced. The reason we did a soft start was due to power failures and his generator not starting the A/C compressor. He has a 11,000 watt generator with a 12,000 watt start. It struggled to start the A/C. After installing the soft start, it started the A/C with no problem and continued to run along with 2 refrigerators and fans in the house. A little piece of security now when the hurricanes come and power is out. I would highly recommend spending the money on this particular one. It may be a little more but is well worth the ease of installation and the fact that it works with no problem. Just my opinion.
