If that's the case, I would imagine the new equipment would not matter if it's variable or 2 stage or single stage. Things may have changed in how systems are zoned but that seems like a lot of money for an upcharge to a 2 zone duct system that is already in place. Good luck.

If he goes with a single or two stage unit then he can reuse the existing zone controls. If he goes with a variable speed inverter system then he needs the zone controls that can be variably opened and closed that work with that system vs the existing zone controls that are either Full Open or Full Closed.
Some companies don't want to do duct work and always charge more others charge less for the same thing. I would get a couple more quotes.
