HVAC Planning during a retrofit
I’m in a situation where I have to replace my roof, siding, windows and add some interior insulation. My interior insulation retrofit will take a few years as I plan to go room by room.
As part of the interior work I want to remove my baseboard and install heat-pumped based heating – ducted on one floor and mini splits on the other.
I have two questions:
– How should I size my installation? Do I do an installation now based on the current zero insulation or based on the completion of Phase 1 (exterior roof and wall insulation) or based on the final values?
– Should I both zoning a mini split application if I’m going to air seal the outside of the house and have a whole house ERV?
