Rated 5.0 out of 5.0 by Mike22BMIT I just love it.
This replaced a window unit, and It works so much better. Best thing, it's quiet. I had pros install mine. They loved how it came with everything they needed and how nice it was to install. It took them exactly two hours to install and test it. One thing though, I had already installed the 'condenser pad'. The pad needed for the outside unit to rest on. And it must be level. I bought a plastic one for $14 and installed it myself. I'm sure they can do that as well if you don't want to spend the effort and time.
Oh yes, one more thing. You have to have electric run to the outside units location. This cost me another $500. And the actually A/C installation was $1,200. So you need to add those to the total cost. Even at that price, the installers were shocked at the money I saved over buying one from their boss. (:
Overall, I like the auto-rotating louvers (option).

To save time we had the mini-split delivered to my home. It came with easy to read and short mounting and installation instructions well worth reading.
The first task was to measure for and drill a 2.5" hole in the wall of where I mounted the blower and control unit. Drilling the hole in an old stucco house was the most difficult task of the job.
Rather than running the electrical along with the refrigeration lines, I used plastic conduit (HOME DEPOT) and then tied the refrigeration lines to the conduit with plastic straps. Two solid 4" concrete blocks were used to mount the compressor unit, and ensured they were level - using shims and a silicone concrete patch caulk.
Using a mini-split also allowed me to provide electrical service with the circuits we had been using for window units - so this was as simple as running some romex and installing a 15 amp plug with a switch at the plug.
As per instructions, with all the fittings tight, but not over-tight, it was time to use a vacuum pump to remove the moisture from the coolant lines. With a purchased vacuum pump, I quickly found the connection on the compressor is an ISO fitting rather than an NPT thread. I searched for a connection fitting, but found it would take time to obtain it. However, with an extra NPT hose, I was able to cut about 1/8" off the brass female fitting, allowing it to seat sufficiently to allow the vacuum pump to work. Since the NPT and ISO fittings appear the same, it is tempting to not force the NPT fitting on the ISO service fitting - not a good idea.
While vacuum pump worked this gave time to complete mounting and supporting the electrical lines. The control wires are fitted with plugs making this connection very easy - anyone familiar with home wiring can figure this out.
I gave the vacuum about 30 minutes - more than suggested, but more vacuum did not hurt anything.
Now, the fun part - as per the instructions, I opened the liquid side fitting for 10 seconds (with an Allen-wrench), closed it and checked for leaks using a soap spray at the fittings. No leaks - and then opened both valves, and then switched on the power, and then went to the inside to enjoy the quiet and cool start-up. Both units are extremely quiet. You can hardly hear the compressor unit operating standing next to it.
I am very pleased with the install and operation of the mini-split. It came with most of the parts needed for install, and I love the fact I did not need a professional to install it for me. The skill level was in line with automotive repair - say a brake job - only cleaner.
I know this is a long review, but my old house is not suited for central air. Contractors tried to promote the idea of using mini-split blowers on the inside, but all tied to a large honking compressor unit (noise and more noise). This also meant I had to install a separate electrical supply for this honker. Price quoted - $27,000.
I figure 4, 12,000 btu mini-splits will cool my house, but we may have to re-think this as the 12,000 btu unit seems significantly more efficient than my window units, leaving the only reason to install four mini-splits will be to gain zone cooling.
1. Be careful and take time to measure twice and cut once.
2. Don't over-tighten coolant joints.
3. Ensure you can provide a dedicated circuit to feed the unit.
4. Buy or rent a vacuum pump, and ensure you have fittings for NPT and ISO connections. My trick worked, but???
5. Take the time to install the coolant and electrical lines in a manner that will last the test of time.
Be safe and careful, and if you reach a frustration point, stop and research a solution.

I was looking at the Ramsond brand model but it was sold out. I contacted the manufacturer and they told me that they also make this brand along with Ramsond brand. They both have the same compressor and all internal parts are from the same manufacturer.
This was a fairly easy install, just take your time and read instructions carefully. This thing runs whisper quiet. I wired a plug on the end of my unit to make it easier to service or plug into a generator. I would recommend this to any basic diy person don't let it intimidate you.

Bought this unit to heat and cool my upstairs loft. The install was not too difficult. Took my father and me about 5 hours to completely finish. All In all it was a pretty smooth install. I did have to remove the outside units grate and bend the metal on the housing because it was coming into contact with the fan, so make sure you inspect the unit upon receipt. Also have an AC technician pull a vacuum and check for leaks. To insure longevity of the compressor make sure you pull the vacuum. I've read some reviews where people stated there is no need to vacuum but I tend to err on the "it does" side. The reason for the 4 stars is the directions. They are poorly written and not too detailed.

The inside and outside unit was easy to install.
The instructions need better detail on needing to bend the tubing at the wall unit , as it is designed for bending but unledss you unwrap the insulation , you would not know that, Had to have a Heating and Air conditioning guy come out to vac the air from the lines and cut tubing to size needed,and check for leaks when he was completed.
System very quiet, does a Great Job have it in a room 22 X 14

This is a excellent product for the money as compared to other like and kind units on the market.

I installed this unit into a sun-room that is still under construction, so it allowed me to install this over a few days versus all at once and to build everything to suit my needs for this unit.
Electrical: I installed a 20 amp breaker at the breaker box and ran a dedicated 12 gauge line to the unit. Instead of using an outside A/C breaker (which is slightly confusing), I installed a 20 amp double pole light switch for the cut off. The double pole is a true cut-off because it kills both the positive and neutral supplies. The unit itself rates between 15 - 20 amps, therefore I opted to be safe and just go with the 20 amps.
As vaguely explained on the electrical panel cover, brown is black (hot or positive) and blue is neutral (white), and yellow/green is the ground on the provided cabling. You'll notice the empty slots on the right side of the compressor unit, though based on the diagram in instructions, it seems backwards. Pay attention to the letters on the diagram and the compressor unit, which should help you locate the correct terminals to screw the connectors into.
Piping: I had to have the pipe cut and flared to the correct length for my installation by a neighbor who works with copper. After vacuuming out the line (the fitting on the bigger return pipe is of a different size than a normal A/C unit, it's a 5/16" flared fitting), I opened the valves on the compressor and I energized the unit... quickly discovering the pipes were leaking. I shut it off and tightened, but still had leaks. I did not want to over-tighten the fittings as recommended. So I called an A/C guy out and he tightened the fittings more, added some of the lost coolant back and kicked on the unit. Cost me less than $200 bucks. It was worth a shot trying to do it myself though and it didn't kill anything. Better than paying $1000 - $1500 to have someone else completely install it.
The unit blows very cold air and enough to cool my sun-room. The remote is basic but takes a little getting used to because the buttons and symbols are vague. Aside from the hiccup pressurizing the lines I did everything myself and I would do it again.
The only con is the instructions, which cover numerous models.
