Mini split heat pumps are very popular since they cost much less compared to traditional HVAC systems.
They are also very popular with the DIY (Do-It-Yourself) crowd since kits can be bought and installed by a homeowner with no need for an expensive HVAC company.
Mr Cool Mini Split Easy Install Features
- (Quick Connect) Line-Set Pre-Sealed
- Control Lines Clearly Labeled
- Standard 120 or 230 Volts Units
Mr Cool mini split unit is one of the friendliest mini split for DIY installs.
Most DIY Mini Split kits require hooking up a vacuum pump and HVAC gauges to pump a unit down into a vacuum.
Mr Cool units come in a vacuum with a seal at the tips of the line-set, which is broken when it is attached to the outside unit.
Since there is no need for a vacuum pump or HVAC gauges, Mr Cool mini split units are much simpler to install.
Keep in mind pumping down a unit into a vacuum is not that difficult, with many YouTube videos showing the process.
The Mr Cool control wires are also clearly labeled, which makes it easy to hook up.
Three control wires are used between the inside, and outside units labeled 1, 2, 3, along with 120 volts AC labeled L and N.
120 or 230 Volts Electrical
The unit I installed is a 120 volt system and needed electrical run to the outside condensing unit.
The AC wiring is not included and will need to be run from a breaker.
Mr Cool also sells 230 volt systems if a bigger unit is needed.
Other mini split kits can also be bought in 120 Volts or 220 volts systems.
Mr Cool Mini Split Installation
Mr Cool units, in my opinion, are the easiest mini split systems to install and are built for DIY type individuals.
While easier to install, some basic construction skills will still be needed.
The installation is not difficult for a handy person with some basic skills.
If in doubt, be sure to call a professional.

MRCOOL – DIY-12-HP-115B25 DIY 12k BTU 22 SEER Ductless Heat Pump Split System 3rd Generation – Energy Star 120v (DIY-12-HP-115B)
Mr Cool Mini Split heat pump is a good unit that works very well for both heating and cooling.
Do-It-Yourself type individuals will find it to be the simplest to install.
There is no need to buy and operate HVAC gauges or a vacuum pump, which many find confusing.
While easier to install, it does cost more compared to other DIY kits.
I installed a Mr Cool unit in my garage (See video below), and it has been working very nicely, heating in the winter and cooling in the summer.
The unit heats and cools very well with a remote control that makes it easy to operate.
The 22 SEER rating is also very good and makes it a very efficient unit.
Higher SEER units can be bought, but 22 SEER is currently one of the best SEER ratings for a unit.
My thoughts on Mr Cool units are that once installed, they work very well.
They are good for the DIY type person that doesn’t want to buy and operate HVAC gauges or vacuum pumps.
For a more experienced DIY type person, there are cheaper kits that, while harder to hook up, cost less.
I am still testing the unit so far with good results and will update if anything changes.
As always, be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.
