We talked about replacing our HVAC system because of th repair cost. After doing a lot of research I purchased a MrCool 12k BTU for our bedroom. It is Absolutely amazing. Super quiet easy to install no HVAC person needed. We have so work to do in our place and than we will be getting a bigger unit with 2 heads for the rest of the house. Best investment we have made..

Attic Installation
I got this 12K BTU MrCool 5thGen DIY mini split for my finished attic. Installation was straightforward with no issues. I powered it on this afternoon and so far so good. It cooled the attic down to 78 in a couple of hours with the outside temperature over 90 degrees. I am really impressed on how quiet it is. Got the wifi up and running no problem. This is an important feature for me to be able to control AC while I’m away from home. Very pleased so far.
