Ductless minisplit for cooling only
After living with a heat pump on the main floor for a couple of months now, I’ve come to the (unsurprising) conclusion that it has negligible cooling effect on the 2nd floor. The main floor unit was purchased mainly for heating, but I thought I’d just see what it was like with no cooling upstairs. It’s not great. I keep the main floor at 23C, 55-60%RH. The upstairs is typically 2-2.5C warmer, and much more humid.
Anyway, looking for recommendations for models for the upstairs, given that it will essentially never be used for heating. My energy monitoring last winter showed only 10% of the heat delivered to the house was on the second floor; and of that small amount, all of it was to bedrooms, whereas this minisplit will be in the hallway.
I went with a Fujitsu 9kRLS3H for the main floor, based on its cold climate heating performance. Since that isn’t even a consideration this time, is there a more cost effective alternative? Looking for something in the 6k-9k range again. I feel like 6k is probably enough, but I’m guessing there’s not much price difference between 6k and 9k anyway.
