It works fantastic. After that, I bought 2 more 9k BTU for bedrooms. So total 3 mini split cost under $1200. It must cheaper than getting new central AC, and SAVE A LOT ENERGY. Just 10 months, my house save almost $500 compare to last year use central AC. And my house never get cool and warm like this before. If you know how to install mini split, you will love it. It very quiet and efficiency compare to central and window AC.

But you do need to do electrical work. Generally a new line from the Fuse box with a new breaker, and you usually need a shut off box near the outside unit. Both pretty easy to do if you have any DIY skills.
The other thing you'll need to do is use a vacuum pump to clear out the lines before you start it, easy to do, but you need the pump. Lots of youtube videos to watch and decide if you feel comfortable doing it.
My dad does electrical so it wasn't much to run the 240 to it vs using the existing 120v lines. That's the only additional consideration going 24k btu.
If i used this (or similar) on an upper floor about 1200 sq ft but our (double wide) stairway leading to the lower floor is open, would it still cool ok?
will a mini split still cool properly or does the open stairway cause a problem for cooling?
Our lower floor is cool in the summer so we were not planning on one downstairs. In the winter, we use central heat, so no need to use a mini split just for heat. I didn't realize the AC units also had heat!
But would the open dual wide stairway cause any concern for cooling? I'm assuming cold air wants to go down....so is there too much "leakage"?
If that makes sense....
