EasyStart™ - The most advanced & effective soft starter for all A/C applications

EasyStart™ is a one-of-a-kind, custom developed soft starter for single-phase motors like those used in the home and commercial contexts. It employs a 4-part start ramp sequence that is self-optimizing, resulting in the lowest possible start-up current. EasyStart can deliver a start current reduction of up to 75% of a compressor's LRA (locked-rotor amperage). EasyStart is the perfect solution that allows an air conditioner or refrigeration compressor to operate on a generator, inverter, or limited utility power when it would otherwise not have functioned. It can also be applied to air compressors and fluid pump motors.

Two product variants support 2 to 3.5 ton (19,000 – 42,000) air conditioning units and 4 to 6 ton (43,000 to 72,000) A/C units.



  • Perfect emergency power solution on small to medium-sized generators
  • Reduces blinking of lights when A/C starts at home
  • EasyStart Your Home or Business A/C in power emergencies
  • Be the only one on your block sleeping Cool All Through The Night after a weather disaster
  • Supports both 115 and 230 VAC motors.
  • Specialized fault checks not found in any other soft starter provide further protection for your compressor.
  • The EasyStart™368 is capable of supporting up to a 72,000 BTU (6 ton) compressor. It includes a unique water resistant and UV protected enclosure
  • Has the updated technology of Bluetooth which makes it easier for diagnostic!

I bought this Easy Start the end of November and just had the time to install it . Short answer is WOW ! I didn't check the peak inrush beforehand, but the first start was 80 amps ,second was 60 , third was 40.1 . My whole house generator struggled a bit before but I can hardly hear anything at all after only 3 starts . Amazing.......

Great Product and even Great Tech Support...:-)

I’m very happing with my recent purchase of the Easy Start 368-X48 to work with my Trane 3.5 ton unit.

As a DIY, and is typical, this is my 1st installation, it went well, but I was getting a wiring fault upon startup..After a reset of the circuit breakers, it worked with good A/C flow from the compressor.

Nevertheless, via the BT app, I sent them the diagnostics. I got an email reply the next day (that’s Great Service). They asked for more information, and I complied.

Roger from Micro-Air saw that I had the “black” wire on the wrong Connector and asked me to move it to the correct spot. He was spot on.!!!

The unit is well-built and looking forward to using it via my Generator start-up. Again, this is a home-based residential unit and not a typical RV A/C unit.

I don’t have the fancy amp meter but via the BT I’m using less than <20 amp in the running state…Very satisfied, it delivers what is advertised.

This soft starter is a great product. Hutch Mountain had great customer service and responded promptly to my questions. This soft start was on back order from Micro Air, but they kept me informed as I inquired on the status. Once the soft start shipped, I received it in 3 days. Install was easy and lowered my in rush amps from 105.5 (sticker) down to 43 in rush amps. The running amps went from 18 amps (sticker) down to 9 running amps. This will allow me to run my central a/c unit with my 13,000 Durostar portable generator, during a power outage.

Perfect upgrade for our Tesla Powerwall 2 batteries

This product works as advertised and is simple to install. We had a couple of Tesla Powerwall backup batteries installed which have 27 KWh of storage and decided to install a soft start so we can reduce the initial load of our 3.5 ton RUUD RRNL rooftop package a/c unit.
According to RUUD's specs, the Locked Rotor Amperage (LRA) of our a/c unit is rated at 5.1 amps for the evaporator fan and 112 amps for the compressor. Tesla's Powerwall 2 batteries are LRA rated at 106 amps and run everything in the home during peak electric hours from 4-9pm every day.
Before installing I measured the max amps on the L3 line on the bottom of the contactor and it was 59.3 amps. After installing the soft start and letting it cycle through five a/c startups, it was 15.1 amps!
Installation was very straightforward following the instructions that came with the soft starter. You will need a few crimp-on electrical connectors to connect the 4 wires to the existing a/c capacitor and contactor. I removed the plastic from the crimp on connectors and used heat shrink for a neater finish.
I was able to install the soft start on the sheet metal panel above the existing a/c wiring/circuit board and drilled a 1" hole and added a rubber grommet for the soft start wiring harness to drop into the area where the capacitor and contactor are located. It looks very tidy and sits within the a/c unit so it is always protected from the elements even though the soft start comes in a NEMA3 weatherproof enclosure.
