MRCOOL DIY 12,000 BTU Ductless Mini Split Air Conditioner & Heat Pump, 115V 5th Generation WiFi Smart Control AC & Heater w/ Remote & Quiet Operation

I have had a super good experience with Mr Cool, from before questions on 'chat' to ordering and after installation questions. No doubt I would do it again.

The Mr Cool 18,000 BTU mini split system 5th generation system is working great. I was able to install it myself with the included step by step instructions. I also went with the Mr Cool line cover plates to protect the lines but to also give it a clean finished look.

New pole barn installation, easy and straight forward.

Very good product, I was surprised how good it worked in my small room.

Easy installation and hook up however terminal block mis-wired from factory. After a couple of discussions with tech support( who were great) got wiring corrected and unit fired right up.

This is the best investment I could have made living here in the south. I am very pleased with the features this unit was created with. I use the Sleep feature every night to save on the electric bill and speaking of electric bill mine has dropped substantially since putting this unit in, very efficient. As long as you think through what you are about to do it installs beautifully. The Remote has every choice for your comfort that you could imagine. I am very pleased.

DIY is a great kit. Sealed and easy to install. Want two more for my home.

Great unit and OUTSTANDING Customer Service! Bought this for a detached workshop and worked really well for first month +. Cooled the area down quickly and very straightforward DIY installation. Had a loss of cooling and enjoyed great communication from Customer Service who walked me through some potential problems and when none worked, another unit was sent no questions. New one was a quick install and works perfectly. Very happy! Thanks Mr. Cool!

I am fairly comfortable doing electrical wiring so this was a breeze to install. No special HVAC tools needed! I was quoted 4 times the cost of this unit for a pro to install a similar unit. Mr Cool delivers more features and I saved a fortune!

Just purchased and installed. super easy. No leaks after installing oer i structions.

Bought this during the hottest month for my cottage, installed in a couple hours and ready to go with minimal issues, adding another to a rental unit we own

We purchased this unit for our granny flat. 700 sq ft. Works great! Very happy with install ease, product works great for cool. Haven't needed the heater yet.

Installed this in our fast food restaurant during a mini Midwest heat wave. Our seating area was running 89 degrees during the day!!! And could only drop to about 82 overnight because of refrigeration and “leftover” heat from appliances. Over the first night it dropped it all the way to 65 and was able to maintain 72 the next day with all the appliances on and people opening and closing the door all day!!! I’m impressed.

installation was straight forward and every thing is working fine

Recently installed in our rental and our tenants are extremely grateful with both the design and splendid performance!

We recently bought the DIY 18k unit. We love it. Anxious to see how good it works in winter

Just had this installed this weekend at our cabin I am very pleased with it's performance and quietness. I would have done the install myself but recently tore up my knee and needed help

I just put the unit up and it’s working wonderful and the guidelines are straightforward just follow them to the letter you’ll be happy

Just got this unit and it has surprised me. Now my 1500sqft shop is comfortable to work in.

I got this unit to cool and dehumidify my 1000 sq ft basement compromised of 5 rooms. Mounted in the main living area. I leave the doors open to other rooms open. It handles this effortlessly. The unit is whisper quiet. Followed the instructions, everything worked fine with no adjustments. The instructions can be a little confusing, since some seem to be generic to other units and some seem specific to yours. I watched some YouTube videos from others which was very helpful, then averaged them all and took my path. The units are of excellent quality in my opinion. Give it an A+. The instructions, I would give a C. I plan to get 2 more of these units in the future, for the upstairs. ( I have the 18,000 btu DIY) I feel the 12,000 would have been adequate for me, but wanted to be sure. On a humid 90deg day I think I could cool down to 50deg. My basement is insulated though.
