cheap, installs easy, great product. highly recommend.
Set name: 12000BTU,110/120V
Install is easy and straightforward. User manual is EXTREMELY detailed. Having advice ranging from "don't stick your hand in the cold air or use this for cooking, idiot" to specific torque specs for the flare fittings, wiring diagrams, and step by step install instructions including how to vacuum it. I do NOT recommend installing it with the pipes hidden behind the shroud. There is too little space and it's way too hard to mount the unit when you can't see how the pipes are in the way. Use the side knock out so they can't block you mounting the unit. Pipes are a little short, but this is the cheapest unit on Amazon. If you are running the indoor unit directly above the outdoor one, this is perfect so you don't have loops. So far I'm extremely satisfied with the packaging/instructions/quality of everything. Finished the vacuum/charging and it works great. Pulls around 12 amps at max load and the indoor unit is literally whisper quiet. Way more effieicent than mechanical ACs. If there is a 1 degree difference this will run at 10% to fix it, instead of running at 100% like old AC units. saves tons of energy. Install difficulty isn't too hard for anyone who uses tools or does DIY. install hoses in indoor unit, wrap them, install indoor unit, install outdoor unit, hook up pipes/electrical, vacuum, close, and release charge. I like their instructions step where they say to partially release the high line refrigerant. This means your lines go from vacuum to slight pressure, so when you disconnect the vacuum pump, no air gets into the system. Very good idea. ... show more

Great value for the money!
Set name: 18000BTU,208/230V
Mini split is working great! It’s only a few days after installation but it’s cooling my 450 sq foot garage phenomenally. I live in north Texas and my garage was 95 degrees with 70% humidity. I leave the unit running and set at 80 degrees and it is keeping my garage in the mid to upper 70’s and it isn’t working very hard to maintain it; in fact I can’t even hear it run unless the fan is cranked up. The directions were ok but seemed to be translated from another language or something because certain directions didn’t make sense. I would lean on YouTube for installation videos and tips. This was my first time doing a mini-split installation and it was straight forward. I am a little worried about long-term quality and durability but even if it breaks it’s not a massive loss due to its low price. So far, would recommend it. ... show more

Works for us!
Set name: 12000BTU,110/120V
While some users reported challenges with this product, my experience has been seamless. The unit arrived on schedule, well-packaged, and completely undamaged. The provided instructions were clear, allowing for a straightforward installation that took approximately one hour. Because we plan to sell our house in the near future, I opted for a temporary installation setup. I routed the lines through a window and positioned the indoor unit on an elevated bench, ensuring the condensate drains properly to the exterior. I also added a plug to the unit for standard outlet convenience. Over the past three months of continuous use, the system has performed flawlessly and operates very quietly. Both the heating and cooling functions are highly effective and efficient. ... show more

Porr Instructions and Missing Information - But it works well!
Set name: 12000BTU,110/120V
I would rate this 5 stars but for two things. 1. Instructinos are poorly written and does not include information about charging (pressures, etc) and 2. Customer service doesn't answer emails, or at least mine. It was easy to install, but I'd recommend watching the video several times to be sure you understand how to do each step. The wall guide and wall plate are set up to use 12" centers, not 16 or 20 inch centers like most structure are. When you get ready to seal the opening you drilled and put the tunes through, I recommend using some foam sealer to make sure it's fully sealed. While you are wrapping the line set, I recommend that you put a piece of blue tap to hole the wrap from un wrapping every few feet. That way if you let go or something, you only have a few wraps that need to be redone. Otherwise it runs well, does a great job at heating and cooling, and it was priced well for what you get. ... show more

Good communication w/seller
Set name: 12000BTU,110/120V
Had several questions for seller related to lineset length and factory charge and seller responded through Amazon messaging in a timely manner with useful information (rare nowadays) Only running for 2 days so far but everything working well so far. EPA 608 holder and retired maintenance supervisor so not a complicated install and was blessed to own all necessary equipment. It is necessary to test for leaks (I pressurized lines and indoor unit with nitrogen) and then dumped nitrogen and vacuumed lines and indoor unit down, then verify vacuum holds before releasing refrigerant (R32) contained in outside unit into lines and inside unit. Lines are metric size (#6 & #9) so if lines need to be spliced or extended metric flare tools are required. Otherwise totally basic, no frills unit that exceeded my expectations at this price point. Inside unit shipped pressurized with nitrogen to ensure dryness and integrity of evaporator unit. Inside and outside units packaged well, slight damage to boxes but no damage to units. Metal finish trim grills are replaced by plastic mesh (I assume as cost and weight saving measure) but mesh will serve the purpose and I enjoy saving money. The electrical cover is fastened with 2 screws at top and one at the bottom and the provided knockouts for the electric conduit connections are too large if they are knocked out. Recommend drilling proper size hole in these knockouts with step bit to avoid fitment issues. Related issue is single bottom screw ends up being nearly inaccessible behind conduits, would be better if there were screws at the bottom of the electrical cover that matched the top locations. Overall, minor concerns and running great so far 2 days in. Will comment further if any problems develop down the road. ... show more

Works great
Set name: 9000BTU,110/120V
I put this in my office. About a 10×12 space. It gets cold quick. I can also adjust the vent up or down by remote. I did have to pay extra to have an ac person come out to put it in and drill holes through the outside wall and drain the lines.

It’s powerful enough to comfortably cool (and heat!) my space up to around 750 sq. ft., and it does it quickly. Within minutes, the room temperature noticeably changes, and once it reaches the set point, the inverter technology keeps it steady without constantly cycling on and off. The 19 SEER2 efficiency rating really shows in day-to-day use. It runs quietly and doesn’t spike the electric bill like older window units or central systems. The 115V setup was perfect for my home, and the pre-charged condenser plus included installation kit made the process much smoother than expected (especially if you’re working with a professional installer). I also love having both cooling and heating in one system. The heat pump works great during chilly mornings, so I don’t have to switch to a separate heater. It’s a clean, ductless look, and the indoor unit blends in nicely on the wall. Overall, this mini split is energy-efficient, quiet, and powerful. If you’re looking for a reliable all-in-one heating and cooling solution for a medium-sized room, this is absolutely worth it. ... show more
