  • 21.5 SEER rating ENERGY STAR certified: estimated national average annual operating cooling cost is 70 USD based on AHRI certificate #9150138
  • Package includes: stylishly designed interior white wall-mount air handler with LED display; exterior pre-charged condenser with special golden anti-corrosive coating coils; wireless remote control for customizable airflow and temperature adjustment; 25 ft. complete kit
  • 25 ft. kit includes: copper tubing with insulation and nuts, control wire, 6 ft. drain hose, wall sleeve, wall sleeve cover and tape
  • Electroplated coils: the electroplated hydrophilic coils improve heating efficiency by accelerating the defrosting process; the unique anti-corrosive coating on the coils also aids in withstanding the effects of salty air, rain and other corrosive elements by allowing contaminated water on the coils to run off more quickly, reducing the corrosive effect to the coils; heat exchange performance is much longer lasting
  • Low ambient operation: a special built-in low ambient kit can be used in temperatures as low as 5°F for cooling operation, useful for users who need to maintain cooling during winter
  • Refrigerant leak detection: with this new technology, the system will alarm when a refrigerant leak is detected
  • Dual sensor fixed or remote: by switching to remote sensor and keeping the remote close to you, you tell the air conditioner to set the temperature from wherever the remote happens to be, this counteracts the tendency for the air conditioner to stop cooling or heating because the air around the unit has reached its set temperature (switches off after period of inactivity to preserve battery life)
  • HEPA filter included (1): a HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites and tobacco smoke
  • 2-direction air vane technology: in cooling mode the air vane opens counterclockwise to direct air horizontally, allowing for an even cooling effect; in heating mode the air vane opens clockwise, directing air downward, this time for a uniform heating effect
  • Built-in electronic diagnostic: monitoring some abnormal operations or parts failures, microcomputer of the air conditioner will switch off and protect the system automatically; meanwhile, the error or protection code will be displayed on the indoor unit
  • Outdoor pan heater: a heating belt is fitted on the base plate of the outdoor unit to avoid accumulation of rain, snow or water on the base plate
  • Dual washable filters: a good air conditioner should not only take care of the temperature in your home but also the quality of the air you breathe; the system aids in removing most of the pollen dust, smoke and other microscopic airborne particles that by latest thinking contribute to respiratory problems like asthma and hay fever
  • Self-cleaning: by pressing clean on the remote control, it automatically cleans the evaporator to aid in reducing buildup of bacteria and keeps the air fresh
  • Sleep mode: in sleep mode, the unit automatically decreases the heating or increases the cooling by 1° per hour for the first 2 hours of use, then holds the temperature steady for 5 hours before ceasing
  • Low noise airflow system: without decreasing the airflow volume and capacity output, the large-diameter cross flow fan can bring down the indoor unit noise level by lowering the fan speed
  • Anti-cold draft: if the unit is turned on in heat mode when the ambient temperature is low, it will warm up prior to fan operation to prevent cold air in heating mode
  • Louver position memory: the set louver position is stored in memory by the microcomputer and the louver returns to the stored position when the next operation is performed
  • Turbo mode: this function enables the unit to reach the preset temperature in the shortest time

Taking a quick stab:

No duct work is obvious.
On demand which can save heating/cooling bill.
More precise temperature control "zones".

The zones play as double edge sword, when moving in or out the heated/air conditioned space takes some getting used to.
The indoor unit hangs on the wall compare to just a register, so the wall is more or less occupied.
Have to run additional electricity to both in door and outdoor units and the tubes from the indoor unit to the outdoor unit.
More filters to clean.

I'm not aware of any. I have two (different brand) installed in my basement. Just need to ensure there's a way to route power and refrigerant between indoor and outdoor units. And of course you need to be able to run a condensate line from the indoor unit to a drain.

We have an 18000 Mitusbishi in our 2 car garage in Palm Springs. When it was 122 out a week or so ago, it kept the garage at 83 degrees. The remote control thermostat isn't the most accurate on this, so I keep it set at 84, and the temp I see across the garage is between 80 and 82.
Our garage door faces west, so I painted it white a year ago, and that made a big difference. It is a steel door that I added the insulating panels to. We also insulated the ceiling when the mini split was installed. It is a finished garage, one half is storage and workshop, the other half is where we park our electric car, so that was the reason for having the AC. Water heater, central AC and solar inverter are all in there too, and two of them give off heat.

I questioned whether the 18000 would handle the garage, but they told me it would, and if it didn't, they would upgrade it to the 24000. Two years in, and it has been great.

When we pull the car in after it has been out in the heat for hours, the unit ramps up and I haven't seen it go above 85 in there for about an hour. The car is plugged in at that point and running its AC unit to cool down the battery pack and electronics as well, so it is pumping heat into the garage and the mini-split is transferring it outside.

It did cost $4,000 for the unit to be installed with a new electric ciruit run to it, a trench to run the lines under ground to the outdoor unit, and the insulation in the ceiling. We could have gotten a Samsung for $200 less, or a Daiken for $1000 more. But, wanted the Mitsubishi. Wish I had a couple of them to cool the house, or at least the bedroom at night instead of running the 5 ton beast!
What type of insulation?

It was blown in fiberglass. The rest of the house has rolled fiberglass.

Seems like a good deal. Does anyone know how these compare to the MRCOOL DIY units?
12 SEER is garbage. MR COOL is 20+
