Works way better than any ac unit I ever gotten. Easy to install. Quiet as heck! My electric bill didnt spike up the fan speed was fast yet quiet. The size is perfect and energy efficient! Very good quality.

I INSTALLED 2 3 TON UNITS AT MY TINT SHOP AND THEY WORK GREAT. JUST INSTALLED A 12000 BTU MR COOL IN MY BEDROOM AND IT IS AWESOME. KEEPS IT COLD FOR SLEEPING AND SUPER QUIET. I AM GOING TO CONVERT MY HOUSE TO ALL MR COOL MINI SPLITS. NEXT PURCHASE WILL BE 1 CONDENSER 3 INSIDE UNIT SYSTEM FOR MY KITCHEN-LIVING ROOM-FRONT BEDROOM. WHY WOULD KEEP THE WHOLE HOUSE COLD WHEN YOU JUST DO IN THE ROOM YOUR SLEEPING IN THAT NIGHT.BIG SAVINGS ON YOUR POWER BILL. MR COOL IS THE BEST. I ALWAYS HAVE THE AMAZON WARRANTY ON IT FOR EXTRA PROTECTION.

The manual is garbage; it doesn't match the actual unit. There is absolutely and precisely zero tech support. If you call the tech support number and wait on hold, you might actually speak with someone but that person only knows what Air Conditioners are but not how they work much less how their own products are set up and supposed to work. They may take your question and supposedly start a chat with someone that does know but that person apparently doesn't know either.The product shipped did not match anything from any manual; the only similarity was the name. The product also did not come with refrigerant installed despite the manual stating that is does so that is a hidden cost. According to the manual, the refrigerant is supposed to be on the high pressure side, behind a valve that isn't to be opened until the system has been evacuated/vacuumed. The manual assumes that the refrigerant is there and so doesn't provide the recommended amount of R410A that should be installed by default. I attached the page from the manual as well as a picture of the actual unit... The low pressure side is the larger of the two hoses so, while the manual got that wrong, a proper HVAC installer should know.Beware when contacting a HVAC tech because they will, like me, assume that this product is like pretty much every other mini-split sold, comes with accurate documentation and is well put-together but when they are onsite and it isn't any of those, be prepared to open your wallet.There are too many viable competitors making competent machines to put up with shoddy products like this. I have purchased mini splits from other brands and they work just fine. Save yourself the frustration and just get a different brand.

Really love this unit. It heats and cools our small space here in Florida and keeps the electric bill down too. The app controls it when away or at home although quirky. The remote control is great. It was fairly easy to install and doesn't take up much space. Lots of YouTube videos show you how to do it.You have an inside, small hang on the wall unit, and a small outside unit. Very quiet. We don't even know if it's running or not until we walk up to it and feel if air is blowing or not. Really can't hear it run.No problems with it and I would buy it again.

Update 1/11/21:Changing rating to 4 stars from 5.Heating is not nearly as efficient as cooling. Here in the Autin area it sometimes drops to the 30s and rarely to the 20s.I've noticed that when the temp falls below 40F it struggles to maintain 68 degrees in the garage.The garage has insulated doors with heated rooms above and on two sides.Yesterday, I noticed it went into defrost at least three times.All-in-all I am still happy, but I had hoped the heating function would have been a little better.Update 10/14: This thing is still going strong. Has run almost every day since June.This thing is awesome!!! Why did I wait so long?Quite as a mouse. Colder than a few hearts I know.Why I chose the Advantage unit over the DIY - Simply because you can't trim the line-set on the DIY. I called MR. Cool and told them I couldn't live with a bunch of coiled AC lines laying on the ground. They suggested the Advantage series. As long as you are comfortable cutting copper line, flaring copper line, running a vacuum and looking at a gauge, then you are set. There are a million YouTube videos showing you how to do it. The unit came with 16 feet of line-set and I only used 50 inches of it.I bought all parts on Amazon except for the conduit, main breaker, and 10 gauge power cable to the disconnect. I also had to purchase a short piece of 3.5" PVC as the supplied sleave for the line-set was too short for my wall.Below are the extra items I purchased on Amazon:3.5" hole saw for brick - tip - rent a nice roto hammer if you need to go through brick and don't own one. - https://www.amazon.com/gp/product/B07ZSRTFJH/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1Power Whiphttps://www.amazon.com/gp/product/B0756N989G/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1Disconnect -https://www.amazon.com/gp/product/B000LF42NK/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1410a Valve Core removal tool - I did not like this tool.

They took it off the pallet and took the pallet with them (which I preferred). The driver was extremely polite.Communication - They (the transport company) kept calling the number on the order, which was not my number. It was an Amazon number in San Antonio. I contacted the seller prior so I had the shipper number. I called the transport company and made arrangements for delivery. I gave them my direct number. However, the driver still had only the Amazon number. Luckily, he called dispatch and they texted me that he was on the way. Could have had the unit on Friday, but got it Monday. Regardless, I was fine with that.Lesson learned - contact the seller and get the transport company contact info and call them.Installation instructions -The manuals are written by someone who speaks English as a secondary language. Spell and grammar check were definitely not used on the install manual. I bought the 24K unit, but the manual is the same for all of them. On page 12 (fig 4.3) there is an itsey-bitsey, teeny-tiny diagram which is needed to mount the indoor unit bracket and locate the center of the hole needed for the line-set. I went online and downloaded the manual in PDF, blew up the diagram and printed it out full page. Note - there is no template with the Advantage Series.The diagram indicates that the vertical center-line for the hole is 151 mm from the center of the right leg of the bracket. There are no reference marks on the bracket to measure from. HOWEVER!!, there is stamped into the metal instructions to measure 120 mm from bracket edge to locate the center-line. So that is what I did.I then went to check my work and measured 151 mm from the center-line I just drew back to the bracket. It came no where near the center of the bracket. So I called tech support for a warm-and-fuzzy. He said to measure about 5 or so inches from edge of bracket. Since the diagram requires you to calculate the outside edge of the unit and then measure from this imaginary line, I asked him about the horizontal center-line for the hole using the bracket as the reference point and he said about an inch up from the bottom of the bracket. Since the hole is 3.5" in diameter I already knew I needed to be 1.75" up from the bottom of the bracket. I politely said goodbye and figured it out on my own.I prefer to work in metric since it is so much easier, but here are the measurements I ended up using to lovcate the center of the hole I needed to drill. 120mm (4.72 in) from bracket right edge for vertical center-line, and 45 mm (1.8 in) from bottom of bracket up for horizontal line. The cross-hair gives the center of the hole. Note: There are other options for the line-set. I chose to have the line-set leave the right rear of the unit.Speaking of measurements - The outdoor unit mounting measurements are in goofy fractions. For instance, 21.26 inches and 350.52 mm. Really? I can't imagine needing to be within 1/100th of a mm to mount a unit. This was more of an annoyance than anything else.Anyway. My point is to take the instructions with a grain of salt. Do your own measurements and math and you will be fine.To the fun part - What can I say? This thing rocks! I was tempted to sleep in the garage last night.Difficulty rating is a "6" on a scale of 1 to 10; Even with the ambiguity of the install manual.The longest part of the process was drilling the hole. I spent 3 hours studying the measurements and also drilling the hole. This also included making sure everything lined up perfectly outside outside. I had the line-set come out perfectly centered between the outside unit and the disconnect.Spent one hour running power. This included the disconnect45 minutes prepping and hanging inside unit. (after getting bracket hung.. See "hole" above).45 minutes hanging outside unit on wall.3 hours making all connections, including trimming line-set and vacuuming system.This was a long review, but I hope this helps someone make a decision. I'm happy with my purchase.

Installed one in my shed and it works Amazing in Heat Mode!

The only difference is this version has uncharged open ended lines. The compressor unit has all the refrigerant you need. The indoor unit evaporator is pressurized with nitrogen an inert gas to keep the unit sealed and assure they hold pressure. You simply need to buy a gage and vacuum set (sold on Amazon for @ $125). Also a connector for the mini split size connection. It is very easy to do and lots of Youtubers to watch.
