There are many types of do-it-yourself mini split kits that can be installed, including Quick Connect units.
Most units require pumping down the line-set into a vacuum which requires a vacuum pump and HVAC gauges.
Quick Connect DIY kits come with the line-set already in a vacuum with a seal that is broken after being bolted together.
This makes Quick Connect kits very popular since they are the easiest to install.
What is a Quick Connect Mini Split Unit?
A Quick Connect mini split is a unit that has the copper line-set already in a vacuum with no need for a vacuum pump.
A line-set is two copper lines that carry refrigerant between the inside and outside condenser transferring heat in or out.
The line-set needs to be in a vacuum as not to contaminate the refrigerant.
Most kits require a vacuum pump and HVAC gauges to pump down the line-set after it is connected.
Quick Connect kits come with a line-set in a vacuum with sealed ends.
The seal is broken only after being bolted onto a condenser.

Our Picks for Best Quick Connect Mini Split Kits
- MRCOOL DIY
- Klimaire
- PerfectAire DIY
Mr Cool units are specifically made for the DIY homeowner to install a mini split as easily as possible.
The line-set is Quick Connect which is simply bolted onto the outside condenser.
It also is a 115-volt system which is often much easier to install compared to 220 volt systems.
An installation will need a bracket mounted on a wall for the inside condenser unit and a hole drilled through the wall for the line set.
The line set goes through the wall and bolts to the outside condenser.
I installed a Mr Cool mini split on my garage two years ago, and it has been worked very well both in the winter heating and summer cooling.

Klimaire also has a Quick Connect line-set kit for a quick and easy install.
The line-set bolts together like most other quick connect systems.
The basic install requires mounting the inside unit on a wall, drilling a 3-inch hole for the line set to go outside, and bolts to the outside condenser.
A standard 115 or 230-volt outlet will also be needed as well as the outside condenser set on a flat solid surface.
PerfectAire is another DIY mini split kit that comes with a Quick Connect line-set.
It is also a 115-volt unit along with built-in WiFi that works with a smartphone app.
Like most units, it is a heat pump which means it will cool and heat.
12,000 BTUs is rated for a space up to 450-500 square feet.
Summary
Quick Connect mini split DIY kits are a good option for those looking for the easiest units to install.
Keep in mind that pumping down a line-set into a vacuum is not hard and fairly simple.
Low-cost budget vacuum pump and HVAC gauges can be bought and used to vacuum down a system.
There are many YouTube videos of doing installs that show the steps.
Of course, Quick Connect units are much easier to install, with no need to worry about vacuuming down the system.
Have installed two Dimstal Heat pumps from Simando, Germany.
Easy installation of both.
Easy connection of the tubes. Remember to open the two hex screws on the outdoor unit. If not, you will not get any heat or cooling. Also, insulate the pipes as well as possible, inclusive the valves on the outdoor unit.
If you have space, put extra insulation to avoid loss of heat if you have long tubes between the units.
Takes a few minutes to start up, by first start, but then it heats well
So if you can use standard tools, you will be able to install alone.
Negative is that the installation manuals often are not complete, but Youtube might be of help.
Something to take into consideration:
Some warranties for non DIY units often require a certified installer whereas DIY (Quick Connect) systems do not (at least for Mr. Cool DIY). Also, Pioneer units installed with Kwik-e-vac do not require a certified technician.
I’ve installed 4 Mr. Cool DIY units. I’ve also installed 3 Pioneer units using their Kwik-e-vac and got a new compressor unit (for shipping charges) when one developed a leak without having to prove it was installed by a certified technician. Just send them a picture of the oil leaking out between the fins.
