Just installed 2nd soft flex on my 9 year old 2.5 ton Bryant AC after installing one on my 3 ton Carrier. Easy to install just follow directions and make sure to disconnect electric and to discharge cap. Spec sheet says LRA 67.8 AND RLA 12.8 Now with flex after 6 learn starts = 19.8 & 9.4 It does the job just hope it will last many years. Ill be trying it on my 13000K Duro max Gen here in Fl.

I have a 5 ton Carrier unit, type 25HBC, with a compressor LRA rated at 132A and RLA at 26.4A. And, a fan rated FLA of 1.2A. Before installing the MicroAir soft start, I measured the total inrush current at 211 Amps, which included both the compressor and the fan. Regrettably, I didn't consider just measuring the compressor inrush. Since installing the Soft Start, I haven't rechecked the total inrush. It's been a couple of days since I installed the unit, and today recorded the App's readout. I didn't know what to expect, but was hoping for a 50% drop of the LRA. So, the inrush going from 132A rated to 34.4A, and the run current from 26.4A to 15.8A is very satisfying. I can now make a decision on which generator to buy. I wanted to install the soft start inside of the electrical compartment of the compressor, but had to move the control board to make room the the Micro Air unit. As you can see, there was just enough room to do so. I left the Soft Start input cable intake until I was confident there were no problems. I'll now cut the cable to a more appropriate length. I'm wondering if it's possible to configure the connections so that the fan inrush can also be reduced. Anyway, very happy.

This is the second burn out I have had in the last year. I have done every thing you have asked me to do to resolve this issue. The white pigtail is becoming shorter and shorter as you can see in recent photo 7/23/2024 I hade talked to at micro air this morning that helped me. She said someone would get back to me as I explained the situation. There is a problem somewhere, and I really need help to resolve this what could be wrong. Really need someone to respond in technical support .

Easy to install instructions Easy to follow Easy start flex home

Living in Houston TX you need AC, and a backup generator. During hurricane Beryl we were without power for almost two weeks. The generator working, but definitely bogged down when we ran the 3.5t unit (only ran one unit). Just had two flex soft starts installed on 3.5 and 5t Carrier units. They are audibly smoother. Fingers crossed.

My A/C company installed this on my Ruud 3.5 ton A/C today. My unit had a LRA starting draw of 110 amps. After the Easy Start Flex went through the learning process the starting amp on his meter showed 33 amps the microair app concurred. Waiting for my 11,000 watt inverter generator to arrive, should run the unit without issue!

I installed the EasyStart Flex in my 3-yr old, 3-ton HVAC compressor. The work took me about 90-minutes start to finish. The EasyStart Flex fit nicely under the corner-cover where the electrical components are. This house also has a 22kw Generac backup generator, and it could barely* start the A/C compressor. I couldn't measure the actual load demand but per the data label on the Compressor unit, the LRA current load is 81.4 amps. The image attached here shows two actual load snap shots, post-install, from the (wonderful!) EasyStart App. There are two screen shots. On left, is the EasyStart when it is supplied power from street utilities. The HVAC compressor now draws max of 20.8 amps (!!). On right, is the same EasyStart when it is supplied power from the Home Generator. The compressor now pulls 26.2 amps, a reduction of more than 65% from the rated LRA current load of 81.4 amps. I'm not surprised it's a little higher on geneset (technical reasons for this). Last, and while subjective, I note what others have noted - the compressor seems to run more quietly, post-installation, than it did before install.

Easy installation, this was installed on existing 3 ton unit that is 24 years old, have been monitoring starts for 11 days now, this is a product that delivers all that is advertised. Overall reduction in rush amperage of 56%. 65 to 28.3 amps reduction…..Quieter, no dimming of lights, works excellent with a small portable generator, MADE IN USA what is not to like…..For me to say that I am extremely pleased is actually an understatement….getting ready to order another one for my good friends who were unaware that a product like this exists…..I am originally from Hightstown and am now in NC, proud to give you my business….

I got this to reduce max amps on my 5Ton American Standard HVAC as part of a solar battery backup project. The goal was to get my max inrush under 50 Amps, and ideally under 30. In HVAC, I learned the term is LRA which stands for locked rotor amps. I consider myself pretty handy, but not at all a pro. I had to watch a couple of youtube videos a few times, but the install was very straightforward once all the wires were identified, and connectors were obtained. The app is primitive, but gets the job done. I went though the trouble of getting an amp meter to take measurements because I'm a skeptic. But the App will give you the max amperage at start up without having to buy a clamp meter capable of measuring inrush.
