Review: Amazing product works as promised…. - I run two geothermal heat pumps - one 6 tonne and the other is 3 tonne. No more harsh startup sounds or light flickers on startup. On first startup in learn mode saw 66% reduction in startup current. Review: Great for making your ac last longer and use with generator when needed - Bought this several years ago cause wanted to put a soft start on ac for a generator use. Saw this on a YouTube video had good reviews and install was easy. So for the last couple years I had it on my ac. No issues so far and the ac start up is a lot quieter and hopefully less wear on compressor. It’s Bluetooth so I get feed back on my ac unit and if I ever need help can call the company and see what the issue is. But so far it’s been good. ## Features - ADVANCED MICROAIR TECHNOLOGY: Micro-Air EasyStart Flex is the most advanced and versatile soft starter, designed for all sizes of residential AC units up to 6 tons (72,000 BTUs).
