Ducted Minisplit and Static Pressure
Edited for clarity
is .16″ wc external static pressure enough to serve multiple rooms with a central return grille ? A contractor is proposing a Bosch 3/4 T compact ducted AH with this esp.
My guess is that these air handlers aren’t designed for multiple rooms. I saw an article by Bailes who used a mitsubishi unit with .20″ for multiple rooms, but the duct work looked quite large – plus he is an expert who likely had a top tier contractor.
