this is rental property that has baseboard heat no ac i'm leaning to toward mini split ,ptac split system 1.5 ton
Mini split or PTHP sounds good but I can't imagine 535 sq ft needs 1.5 ton! Obviously mini will be much quieter, more efficient, can have variable capacity inverter models but lots more money.
The TRUE highest cost system is the system not installed properly...
The three big summer hearththrobs...
The A/C repairman
To know, we would need construction details, orientation of the building, any buildings attached to it?
Also, your location, city and state...
