MICRO-AIR EasyStart FLEX 398 Bluetooth Soft Start Kit for Air Conditioner

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

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!

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.

This is such an improvement for my AC unit which took 160 amps to startup and run at 12 and now it’s 27.2amps to start and still 12 amps to run. Now my generator can run everything in our house. Super easy to install and lots of instructions and videos to help. Great product and definitely recommend!

The MICRO-AIR EasyStart FLEX 398 - Bluetooth Soft Start Kit for Home Air Conditioner, was very easy to install. I had some questions about the app. So I called Hutch Mountain. They were very friendly and professional. install my easy start on my 4-ton Carrier A/C, which required 108 initial starting amp to start the compressor. After installing the easystart, it reduced the starting amps to 49 from 108 amps. within the five cycles for the easystart to learn, the starting amps went down to 28.9 amps. A week later the starting amps are 27.7 to start the compressor. The MICRO-AIR EasyStart FLEX 398 has reduce the starting amps from 108 to 27 for my A/C. A reduction of 75%. I know I will see a cost savings on my electric bill. Also, my A/C unit operates a lot smoother and quieter. Before installing the MICRO-AIR EasyStart FLEX 398 you could hear when my A/C was starting. Today it is so quiet that I have to go outside to check my A/C to see if it is running. My A/C turns on, runs for about 15 to 20 minutes then shuts off and may turn back on 4o to 60 minutes later. I feel and I am noticing my A/C is running more EFFIECENTLY!!! I strongly recommend this product for all to install in their A/C units. What an AWESOME PRODUCT!!!!

Hutch Mountain made this the easiest install ever!! It took longer to find my side cutters than it did to wire and mount Micro-Air EasyStart Flex 398. I have a 3.5 ton outside unit. Everything you need is in the box. Self-tapping screws, zip ties, wire connections plus a 3”x 5” double sided tape to hold on the outside until you can screw on! They thought of everything! So easy I had to call Scott! He answered on the third ring!! Great service! 100% recommend!

I love this thing. Works great, and I can now comfortably use my generator in the event of a power outage. It also stopped the lights from flickering in the house when the AC turned on. It went from 56 starting amps to 28 amps on a 5 ton Trane unit and it took less than 15 minutes to install. Worth the money!

Works as advertised. Lowered my peak start amperage which should save money and reduce wear and tear. I had 1 issue where this device stopped working as it experienced a peak start overcurrent fault. I'd give more stars but I think the software is mediocre and not completely intuitive. The accompanying video and FAQ are very helpful. Even a layman can install this. I have a 5 ton R-22 unit with a LRA of 169amps. I measured 80 peak amps before. 40 to 60 amp peak amps after install. My unit started quieter with this device.

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.
