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.

1) hard to get a response from MicroAir. Very slow. Had to call 2 or 3 times asking for a response 2) got 2 detailed guides for my install. 2nd one was an update on 1st. Don't understand the difference. Tried several times to get clarification. No response. 3) just for clarity, rather than saying "put Easy Start black with compressor common (C) [black] on the contactor behind the screwhead using...." say which contactor terminal. The pic shows terminals T1 and T2. Say "on the contactor terminal T1 behind the screwhead using..." Because you do this every day all day, you forget that most of us are not electricians or HVAC people. We still want to do it ourselves, and we're capable of doing it with just a little more clarity from your end. 4) haven't gotten clarification so haven't installed the Easy Start yet. Giving it 4 stars because that's my hope. I assume you have a great product. You just need a great tech support to go with it. From my experience, you don't have it now. You asked for my opinion. Don't ask unless you want to hear the answer.

I was so happy when I installed and it cut down the starting amps significantly, less noise. I thought the almost 400 bucks had been well spent. Fast forward 4 weeks, wife asking why the house is so hot. Came back home, checked the unit, brown liquid all over. I googled "Micro Air Easy-Start Flex failure", found out I am not alone. Just go read the reddit page. At first I opened a service ticket to see if micro-air would send me a replacement, until I went down the rabbit hole of all the sudden failures everyone else is having on these units, all units failing within a few weeks. Micro Air knows this and they didn't care sending a recall. Many users are posting the interactions with tech support. They know about this and they are just waiting for people to reach out instead of proactively owning their mistake. I was still on the Amazon return window, I've already placed the return order, dropping it off tomorrow.

I bought this unit and installed it on a new A/C unit. When the A/C was installed the breaker tripped durning start up. Checked all connections and tried again with the same result. Contacted the A/c manufacturer and they said to contact micro-air, who asked for photos. Sent all requested information. While waiting for a response I uninstalled the easy start and the A/C worked just fine. Response from support came which said, "Install per the diagram"! No further comments or help. I reinstalled the unit and had an electrician check the 4 connections, and again the breaker trips consistently. Removed it again and the AC works fine. Declared this unit is junk. I would give it 0 stars if I could - and 1 star for the support, because they did actually get back to me even though their response was junk like their unit. Very disappointed to have wasted a lot of money.

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.

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 purchased the Micro Air Easy Start Flex from a local distributor First Source Energy in July 2024. I installed the unit on a 24 year old Trane 5 ton. The LRA on the spec tag is 169. I checked the it with my amp meter and it showed 77.8 amps on startup. However this meter does not have an inrush feature so that number my not be accurate. After the five learning starts the Bluetooth app showed 43 amps. I have checked the starting amps several times with the app and it varies between 37 and 47 amps. I can now start and run my AC with my 12 KW generator which it would not do before. Great product! Easy to install.

Installed my soft start on 5/2023 on a 15 yr old Payne 2.5 ton unit with an LRA of 73 a. My main objective was to run it with my generator with 9500kw starting. Not only did it start up with the gen but the startup is mulch quieter; no more 'rumble'. Also, found my contactor was trashed: brittle plastic that just fell apart. My LRA now runs between 20-40a with a total of 2500+ starts. Not sure of way the variance; usually starts at approx 30+ amps. Overall very satisfied. Install was easy with great cust support. Also have the Easystart on my RV. I can start it with my 2500kw Westinghouse Invertor gen.

I bought an easy start from MicroAir about 3 years ago when I was setting up a portable Champion 8750/7000 inverter generator for emergency purposes to run on natural gas. When Hurricane Beryl came through we were blacked out for 9 days. This easy start allowed me to run a 4 ton American Standard 16seer along with a fridge, a freezer, a mini fridge & 2 tv sets all at the same time 24/7 with no issues. Our days here were 100+. This device may have saved our souls. This device reduced our AC start up from 105LRA to 27.5A. By installing a new compressor capicitor also it came down further to 24.5A. Superb device.

I’ve had the previous version of softstart for a 4 ton unit installed on my condenser since 2020, we just got hit by Beryl a few days ago and lost power. We’ve been out of power for a few days because Texas administration can’t seem to be bothered to hold utilities feet to the fire to fix the grid. Anywho, I’ve been powering my home with a predator 8750 inverter generator in conjunction with the soft start and they’ve both have been great thus far…we’re 3 days goin on 4 without power but aren’t suffering in the heat. If you’re on the fence in grabbing one of these, jump off and get one.
