Have a 2 story 100yr old home (just under 1000sq ft footprint, centre hall design with a rad system for heating) . We have a 10+ yr old ductless LG unit that's split between the ground floor and the master bedroom, the configuration keeps the ground floor cool enough (could be cooler) but the other (2) bedrooms are really hot in the summer (and could be warmer in the winter) . Looks like everyone will be home again this summer, so looking for a whole house cooling option (with the ability to close doors).
Wondering if we should go:
1) the attic cassette route for the bedrooms and use it with the existing ductless to cool the ground floor.
2) New ductless split unit for the 2 bedrooms for cooling (and backup heat in the winter, apparently newer ductless have a heat option?) + upgrade the bedroom/ground floor unit
The windows are relatively new (if that makes a difference) wondering what the most cost effective and energy efficient option would be.
Thanks!
