Mini Ductless Systems
My son owns a home up in Connecticut in which his mother-in-law lives.
The home does not have central air (baseboard heat.)
Currently the house has a portable unit cooling the downstairs and a couple of window units cooling the upper living areas.
Son is considering a Mini Ductless system with likely two or three inside units. He was pointed toward a "Mr. Slim" Mitsubishi unit.
What are some of the considerations that should be looked at when researching such an approach? (I find the Search Function here to be not very rewarding.)
I'll ask my son to read here to see what kind of advice you may have.
