This is my first time installing a mini split. I’m a home builder and like to do projects on my own for my personal house. I purchased this for my pole barn. Install went well and wanted to leave some tips for some one purchasing this. To do this right, you will need a metric flange tool set, grabbed a full set that does metric and standard for under $100, an adapter for vacuum pump when done, pipe benders, Nd proper sealant for nuts. Install took me about 6 hours total and thing runs great and super quiet!

I installed this in a 42' destination travel trailer. The two ceiling AC units were fine, but they were very loud so I was looking for something more efficient, quieter, and something with a heat pump in hopes of reducing the use of the propane furnace during the winter.So being it is an RV, installation is pretty much the same. I was lucky enough to run the lineset down an interior wall so I didn't have to drill directly into the exterior wall. I used 25' of lineset so the original 16' wasn't used. The manufacturer was extremely quick to reply to my question regarding how much refrigerant to add to the added lineset length - which is .215oz per foot after doing the metric conversion.The condenser unit came a little dented on the face which looks like the compressor may have bumped the exterior during shipping. It would honestly be more trouble than it's worth trying resolve aesthetic damage through Amazon or the manufacturer. I would have pursued it if there was mechanical damage.You will need a 5/16" adapter to hook up traditional 1/4" gauges/hoses. And of course a good vacuum. I believe I was down to about 220 microns before I called it and that was after two flushes with nitrogen.Unit purrrrs. The condensor is extremely quiet. I do get a little hum or resonance from the inside and it could be because I have it mounted on the paper thin back wall of the RV, or maybe it's slightly out of balance from shipping and denting the side. The wire cage of the condensing unit shakes just a bit when it's running. I don't want to pursue this because I am not 100% sure the shipping damage causes the slight vibration/noise. The indoor evap unit runs so quiet... we love it. We can talk normally and watch TV at ease. The comfort is much, much better. Even with a slight hum from the condenser, it's so much better than the Coleman Mach rooftop AC units that are super loud and blows too hard. The cycling on and off would drive me crazy. This minisplit just purrs - and we love it! I can't comment how the heat works because it's still summer. But I am hoping it will do ok with our mild south-eastern winters.My only complaint or beef is the wiring diagram for the indoor evap unit. It is wrong on page 24 of the manual, as others have pointed out... but nobody stated how to correct it! Should I? Of course! Let me save you a little bit of pain...MIRROR THE WIRING ON THE INSIDE UNIT TO THE OUTDOOR CONDENSER. The diagram for the condenser is correct. Wire the indoor unit the same. So look at the wiring diagram for the outdoor condenser for both. L1 - S - L2 is correct for both. Page 24 says L1 - L2 - S and this is WRONG.I got this unit on Amazon Prime day with 20% off, making it a decent deal for an 18k unit. I am a licensed/EPA certification HVAC guy who's been out of the field for a few years but I still have the know how and tools. Install can be done by anyone with a basic understanding of electrical and refrigeration. DO YOUR VACUUM. I cant stress that enough! And ALWAYS use nitrogen when brazing - but you'll probably using flared connections.Good luck!

When remodeling a 1903 home, we needed a source of cool air. Adding a central air unit was going to cost $13,000. Instead we went with this mini-split. There were great instructions on you-tube and my husband and I were able to install most of the unit ourselves. We did need an electrician to run the electrical to the unit which cost us $350. The hardest part was drilling through the homes wall to run the hoses connecting the inside unit to the outside unit. The unit works beautifully, is quite, not unattractive, is up out of the way and much cheaper than our previous options. I would recommend if you have a two story home you put one up and one down. Very happy with this product.

Got the installation done in about 6 hours. I’m not a professional but I’m sure a pro could do it even faster. Works great so far! This unit does come precharged in the exterior unit. Charging it was simple but I did need to buy an adapter for my manifold to hook up to it. It’s quiet so far. Blows super cold.

Line set is metric even though they advertise that it’s SAE. Probably won’t be an issue for you unless you need to cut your line and create new flares. I was stumped by this and even referred to the manual over and over again. What a headache I went through 5 flare tools before improvising and wrapping the pipe with tape to get it to fit tightly in the flare block. Otherwise super easy install but beware if you need to cut your line it’s not your flare tool! It’s metric pipe!

Install went well enough and it works well so far. I like the remote better than the MrCool that this is replacing. Heats and cools my 18x30x12 room nicely. Wifi control with the Gree+ app is good. Only time will tell if this was a good investment, but seems good so far.

Looks like a return. Missing the wall unit, remote and maybe more.

I decided to DIY my mini split install after getting a $8000 quote. The install of my 18,000 BTU went well I was able to get it done with minimal issues. I would suggest a new DIY'er to order a copper pipe flairing tool with a pipe cutter and a copper pipe bending tool along with a vacuum pump and gauge set which would amount to a extra $250 but far below what a contractor would charge to install. For a straight install into a wall I cut my copper pipe about 5 feet and flared the ends for a easier install into the wall then connected the other flared portion of the pipe outside, that made my install easier than pulling 25 feet of copper line outside.
