Mini-split, air circulation and noise transmission
We are considering using a mini-split system on our new tight home (double wall cellulose on a insulated slab) in Upstate NY (Zone 5a). We are both consultants with full time home offices.
One option is a hidden short ducted system on the first floor (1,500 sf) to duct air to the main living area and the master bedroom area and a regular mini-split unit for the upstairs (800 sf) where we will have our two offices, a bath, storage and a guest room. Our mechanical room is on the second floor. I don’t want a visible unit on the first floor.
I don’t mind a visible unit on the second floor but I am concerned about comfort in our offices given that we will want to keep the office doors shut because we are often on the phone at the same time. Any openings (jump ducts or undercutting the solid doors) that will let the air circulate will also allow noise to transmit.
Any thoughts on a cost effective solution that provides comfort and keeps the noise out. We also will have a HRV or ERV and a wood stove with an outside air supply. The floor plan is attached.
