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 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. Works fantastic!! set: XtremepowerUS 3CFM 1/4 HP Vacuum Pump HVAC R134a R12 R22 R410a A/C Refrigeration AC Manifold Gauge, Adapter: R410a Charging Vacuum Port Adapter Brass Converter with Thimble 5/16 Inch Female Quick Coupler to 1/4 Inch Male Flare for Mini Split System Air Conditioner HVAC Refrigeration Service (2 Packs)

When I first got this unit I though it was great. Unfortunately that feeling was short lived. The unit worked fine for 2 years. I only used it for the summer months in my man cave when it was hot outside. Then it suddenly stopped working! I had to get an HVAC Tech to come and check it out. The compressor was shot. When I contacted the company they told me that my warranty had expired and they couldn't help me. The warranty is only 2 years!!! That fact that they only offer a 2 year warranty shows that they know the product is complete crap! I have used small window units that cost much less that have lasted much longer! DO NOT WASTE YOU MONEY ON THIS OVERPRICED CRAP!

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.

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

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.

This item is NOT the Do-It-Yourself Model. Even though the guts are identical to the DIY, it takes more thought and effort to install. You need some special tools, like a vacuum pump, a good flare tool, tubing benders, and some beforehand practice with the flare tool to do it. If you take motors apart, build machinery from scratch, or are a plain dedicated do-yourselfer, you can do it. If you're not willing to invest the time studying up on it and practicing with the flare tool, you'd better forget it. Go with one of the DIY models.Mine works great. I have an 18,000 BTU model installed in a 700-square foot (insulated) garage.The temperature drop across it is about 38 degrees (if room air is 80F, output air will be about 42F). It has no problem at all cooling the place down quickly. It appears to be very smart, only putting out the temperature needed to maintain the setting. It may start out at 42, but after 20 minutes it might be doing 58. The fan is nearly silent.
