Ductless mini splits in Mass?

[Chris Roche]

I am wondering about ductless heat pumps and AC in Mass.  I have a two family. I currently have electric heat and one electric 80 gallon tank.  I would like to convert to Gas to save money on utilities and to look better to long term tenants.  I would also be adding two tank less gas water heaters.

One unit is about 1000 square feet, 1 bedroom.

One unit is bigger with 3 bedrooms, large kitchen and a living room.

My question is with the mini ducts, how are they able to keep bedrooms warm/cool with the doors closed?

Are the mini ducts a good option or is there another solid option?

I would be financing the project through Mass Save.
