MRCOOL DIY 4th Generation 36,000 BTU Heat Pump Condenser - Energy Star 230V, 18 SEER, 25ft Line Set

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.

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.

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.

I spend a lot of time in my garage and was heating it with a pellet stove and kerosene heaters and found that to be time consuming and expensive. I don't usually keep it heated when I am not using it so to heat the garage it takes time to get the pellet stove running and for the garage to heat up. So I bought the Mrcool 36000 diy mini split. I am a Electo- Mechanical Technician so the install was simple for me but this unit is heavy so I suggest help and to consult an electrician on your local codes. The install took about two and a half hours with help not encluding the electrical which I had done on the previous day and it could not be any simpler. The hardest part is hanging the airhandler thats where you need help pulling the tubing through plus i installed the condenser on a side mount bracket and needed help lifting it on. After the install I turned it on and could not believe how quite and hot the air was. I also tested the cooling and now will have the coolest garage in town. The ability to control this unit using the app on my android phone from anywhere is great. I can turn the unit on before I got into the garage and have it heated or cold and ready to go. I suggest this unit to anyone who needs to heat a garage or larger area. The only thing that could be improved on is that this unit requires a 35 amp circuit feeding it and the electrical terminals in the outside unit are to small for 8 awg wire so most do it yourselfers are not going to have the equipment to crimp on the one hole connectors required to make the connection so an electrician might be required to do the connection.

I bought and installed this in August, 2018. Installation is definitely a 2 person operation. Fortunately, my brother is a carpenter/contractor. Installation took us 4 hours, start to finish. Very happy withe the performance and energy efficiency of this unit. I've used both the AC and heating functions. I live in the mountains of North-central PA. I haved used the heat quite a bit this winter and it is a great back-up for my wood stove. Very happy with this unit.

I recently purchased this system to heat and cool my home workshop building. It arrived in very good condition with no damage either to the packaging or the unit itself. I had watched several Youtube videos showing individuals installing the systems they had purchased, and was impressed with the "DIY" feature, as I really didn't want to spend the money to have a licensed HVAC tech do the install. The installation manual, while not being overly detailed, did provide enough information to perform the install without any problems. It took two of us about a day and a half, and when we applied power to the outdoor unit, it began supplying hot air as expected. I'll have to wait until next summer to fully check out the A/C side of the system, but so far I'm very pleased with my purchase.

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 installed this unit in my home in August, 2018. A/C works fantastic! Cools my entire home, with the aid of a box fan to circulate back the hallway to the bedrooms. Very efficient too! My electric bill was quite a bit lower than when I used our central air unit. (It was a 30 year old Carrier and it finally died..). I used the heat pump function as a back up for my wood stove. Works very well as long as the outside temp is 30 or above, which is normal for a heat pump. They are not built to handle frigid weather so the woodstove was necessary from December through February. Installation was simple but having a second person to help is pretty much necessary. This is the largest unit that DIY sells. Smaller units would probably not need a second set of hands. Overall, I am very happy with this unit!!!!

Great unit. It cools and heats my 24' by 46' (insulated) shop with no problem. Installation was easy and it looks nice on the wall. It is super quite. On the first day of start up I ran the diagnostics as instructed and it passed all of them but the next day the display had an EE error which was low gas. Even with the error it was working fine but I called an HVAC and he added gas. This condition may have been my fault if I lost some gas while making the connection. You should plan ahead for any extra line set that you may have. I coiled my extra lines on a hose reel mounted to the outside wall; it looks OK. One of my best buys.

I have a 1,000 SqFt garage with high ceilings and thought this would do a better job heating and cooling. It does work but doesn't do enough. I am still working on insulating the whole garage in hopes that once its finished this unit does a better job.
