Been 9 months since I have installed this in my garage and so far so good. I installed it in a 25x25 foot garage, made of cinder block. I insulated the ceiling with attic insulation bare and set it to dehumidify the garage at 72 degrees. I live in Northwest Florida where today it got up to 93 degrees at a humidity level of 77 percent. The garage was at 71 with a humidity level of 30 percent. My electricity bill went up about 20-30 a month but the value of that is a garage that keeps my stuff safe from humidity and the resulting mold and creates a workspace that is comfortable to work in when it feels like hell outside. And this is all with no insulation on the walls and the non-insulated 16 foot wide by 10 feet tall garage door and 12 foot ceilings. Self installation was a breeze, all you need is a cheap vacuum pump and some gauges to ensure you have a tight seal before you let the refrigerant out into the system or for a nominal cost you can self install and have a certified HVAC guy or gal come out and make sure everything is kosher before you start it up.

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.

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!

EDIT 10/8/2025 - We've had this unit for almost 1.5 years now. We live in our RV full time on our property and went through two HOT southern summers and a mild winter with rare snow accumulation that lasted a few days. The minisplit has performed flawlessly. The heat pump works well in our climate and has "kept up" even in the single digits. It does struggle to maintain at those temps but that is expected with a heat pump with no aux heat strips. We have not used the propane furnace at all since we've installed the minisplit. We use the electric fireplace to take the edge off at times but it isn't really necessary unless it's really cold - and it's still more for comfort. We also use a small electric space heater in the back bedroom at night for additional comfort while we sleep. The best part is we have not had to get propane since we installed this minisplit and no more roaring furnace! The temperature stays pretty consistent unlike the gas furnace constantly cycling on and off. Propane is only used for the stove/oven. We've not encountered any condensation leaks or drain problems. But... whenever I install minisplits - I always mount the wall unit slightly tipped towards the drain. It's not enough to see with the naked eye, but enough to see it on the bubble of a level. This helps water drain to where it needs to. 100% happy with this minisplit. Original Review in Aug 2024: 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!

If you cut the line set it's metric , had to buy a Metric Flare Kit. , I already had SAE flare set

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.
