Ducted with multiple zones
5000sq ft home in Massachusetts,currently oil boiler and ac unit with 3 zones. One zone upstairs, finished basement and main level share a zone, but there is automatic damper to effectively make it 2 zones.
I'm reading about ducted systems not handling multiple zones well, but I'm not sure if it applies to what the setup would be for my home. They are suggesting two heat pumps that will utilize existing ducting and leave the oil as a supplemental heat source for colder days.
The oil boiler actually has about 5+ years left on it, it's the AC unit that is influencing the switch to heat pump now. Oil will continue to handle hot water until that dies.
Any feedback appreciated, especially around understanding if the multi zone situation is a issue for my setup and what it actually means. Bosch and Mitsubishi are the 2 options on the plate.
