This is just a draft.... long story short, this is a wise investment, rather than a window unit, looks bad, sounds bad, and the other alternative to replace you entire home A/C.
Later on we will include the how to install.
We recommend a few more items for your installation
Hopefully you have one, if not, borrow one, or buy it. You need a vacuum pump. The unit will last what it suppose to last, otherwise you are setting up yourself for failure and replacing or repairing the unit sooner than you think.
