Mini‑split Air Conditioners

[Larry Callahan]

I installed 3 mini-splits in the garage of my old house over the years, and insulated the garage doors and attic space above it. I had a genuine 72* working environment. Recommended.



However, the inexpensive ones that are pre-charged will almost certainly require annual maintenance, recharging, etc. Do yourself a favor and spend a few hundred dollars more and get a Mitsubishi unit, and have it professionally charged. Then you should have 3-5 years before maintenance is needed. That was my experience at least.

I'm comfortable installing and even evacuating it and charging it myself. I just thought that the full DIY kits can't possibly work as well or better than one that needs to be charged.

In in the end I would install it myself but I would call a professional to charge it.
