Installing a mini split does require some constructions skills such as connecting electrical and using power tool.
The template will be included in the kit and needs the bracket level on good studs along with the hole cut out at the right location.
A unit with a leak will lose its vacuum.
This requires a HVAC vacuum pump and gauges with many low-cost cheap sets available if needed.
The electrical also needs to be run from a breaker for the unit to get 230 volt AC.
The control line are also run between the inside and outside units.
Both units are clearly marked with the numbers 1, 2, 3 which match inside and outside along with L1 and L2 which the AC power goes to.
Daikin units like most all mini split packages operate very quiet with only the fan blowing out air being heard.
The kits has a 17 SEER rating which is very good and low-cost to operate.
Most all mini split packages have a good SEER rating ranging from 16-23 SEER.
Since heating and cooling is what cost the most on an electric bill a high SEER rating brings running cost down and one of the reasons mini split units are so popular.

I installed a Daikin unit 3 years ago and it is still working very well both heating and cooling.
I have installed many mini split kits and have no problem recommending Daikin units.
As an HVAC tech the last company I worked for only installed Daikin units as they are well built with a good warranty.
The installation is the same with most all mini split kits with many YouTube videos on how to install one.
If you plan to install the unit yourself be sure to watch a few YouTube videos first.
Of course a professional HVAC company can be called for the install.
During the summer it cools very well with different sized units for more or less cooling power.
During the winter it also heats nicely with no problems even on very cold nights.
I am still using and testing the unit and will update this post if anything changes.
As always be sure to read the reviews on Amazon, forums, here, or elsewhere to be sure an adapter is a good fit for you.
