I put 2 mini splits in the house last year. They have done an awesome job. The house has been cooler and used less power. You have the added bonus on heat. They will heat down to a pretty cold outdoor temp. I bought the regular mini splits not the DIY version. Saves a lot on money. The regular mini splits come precharged. Hook up the line set, hook up a vacuum pump capable of drawing down to a deep vacuum. Verify vacuum is holding, if yes then release coolant.
The love for fishing is one of the best gifts you can pass along
