If you haven't heard of it, make sure you use https://ashp.neep.org/#!/product_list/ https://ashp.neep.org/#!/product_list/ to help pick a model. One tip from my install, is to go with single zone units. I did a multi-zone and the way the control system works is kind of weird. They also don't have as good of a turndown ratio[0] as smaller/single zone systems, making it less efficient. Overall I'm happy with it though.
