18,000 BTU 1.5 Ton 19 SEER Ductless Mini Split Inverter+ Wall Mounted Air Conditioner with Heat Pump 208/230V

Love the unit but can't read the tiny remote selections. How about a better remote.

Easy install, works very well and very quiet, only issue is the line set is cheap. High side line leaked at both ends, had to cut and re flair and line cracked after flailing. Once shortened a second time on 1 end the system vacuumed down and held vacuum.

Operated perfectly up until this past Monday. Unit no longer cools to desired setting. A tech from A.B. May came out and found that the unit had a singed system board. $800 just for the board. May also need freon.

I DIY installed this one. It was overall pretty straightforward but it definitely is a more advanced skill level. I have a background in automotive a/c so I own a vacuum pump and understood what to do. I also had to reflare the lines because on the indoor unit side, the lengths are uneven so you don't have both connections at the same place, which makes sense because it would make it hard to stuff into a lineset cover if they were both at the same spot. The problem is that the lineset was backwards from the lines coming from the air handler. For example, the air handler had a short suction line and a long discharge line. The lineset should have a long suction line and a short discharge line so everything meets up. Well the lineset had the long discharge line so the suction line wouldn't meet. That was dumb, but fortunately I have the correct flaring tool so I was able to correct it. Also took a few feet off the other side for the condenser unit since I didn't need quite 16 ft and didn't want to do something like coil the line behind the unit. As far as performance. It's fantastic. I installed it in early spring and we had some chilly days so I actually got to use the heating function first. It heats well but we're talking about days in the high 30's/ low 40's. One word of note is that for the heating function. you kinda have to use the follow-me function on the remote because without it, it senses indoor temp from the air intake at the top of the unit. Hot air rises. See the problem? The heat it's producing rises to the top of the room and makes it think the room is warmer than it is, ending the heating cycle before the actual room is heated. For cooling we've had a few days in the 90's already and it has absolutely no issue cooling my entire 800sqft first floor without breaking a sweat. There is one issue that is somewhat annoying, in that it either overcools or undercools depending on what it feels like. Usually by 2 degrees. If I have it set to 77F, it will allow cooling to as low as 75F (even with follow me enabled). Or sometimes if it's satisfied and it turns the compressor off it will sometimes let the temp get as high as 79F before it starts cooling again. This 4F swing may not seem like a lot but I can definitely feel it. The unit knows what the temp is because this is what its reporting via it's own app. I have a Midea (yes this Pioneer unit is manufactured by Midea. Everything is) inverter window-ac which is very similar in operation to this mini split and it does the exact same thing. This is just how they have their temperature controlled strategy programmed. A few more notes for the nerdy or anyone deep into home automation. There is an optional wifi dongle available for it for control through the Midea app. I actually already had two of these dongles because 2 other window a/c's I have came with them (also both manufactured by Midea). They're OSK103 dongles. I plugged it into the Pioneer and it works. Here's where it gets interesting. Despite what it looks like it's not a USB stick rather it's a serial UART connection. There's an open source project that allows you to use a software package called ESPHome on ESP8266/32 wifi microcontrollers that allow you to bypass the Midea app altogether and use it in Home Assistant. I tried it and it actually works great. Through some automation programming I should be able to work around the above mentioned temp control issues by shutting the unit off if it starts acting dumb and overcooling the room.

This is an amazing mini split, and the price is fantastic. If you have a little DIY abilities, just watch a video setup and thoroughly read the instructions and you should be good to go. Make sure you pick up a vacuum pump and manifold. One thing I wish I purchased was a pipe bender, I used the coil springs and it was a lot of work. Also, grab a disconnect box, and a AC pad.

Great buy

I installed this unit this summer in my garage. It is roughly 1000sqf and it cools it very well even in the 100 degree heat. Now that temperatures are dropping, I’m able to keep an ambient temperature at all times. Very quiet, and easy to install. I did have to hire an electrician do the electrical portion. Very pleased with it so far.

The unit is extremely quiet and seems efficient. While the directions are a little lacking, the installation is relatively straightforward. The only reason I didn't give it five stars, is in comparison to the 3rd generation Mr Cool in our garage the Mr cool has more features and the installation kit a little nicer. I would buy this again.

Simple ice cold silence unit

Installed a month ago by myself in an area above the garage in our house that gets very hot due to solar heating in the sunny Colorado summer. Previously we had both a window ac and a floor ac units which were loud and cumbersome and less effective. This mini split is almost silent and keeps the 600 sq foot area very comfortable. I have been keeping in set on 75, fan set on AUTO and it rarely runs above the lowest fan setting to keep the area cool in the 90* degree temps we've been having lately. Installation is straight forward, care is required in working with the copper lines and a small vacuum pump is required to evacuate the lines once connected, but the condenser unit is precharged with all the refrigerant needed. I added a conduit kit to cover the exterior lines. Everything else required was included in the kit, well packaged and instructions are pretty thorough. The folks at our local Home Depot are very helpful and knowledgable here in Boulder Colorado.
