Basement as cold/heat source
My home has about 1313 sq. ft. living/dining/kitchen area (open floor plan) with about 723 sq. ft. of bedrooms on the side. Similar layout in the finished/conditioned full basement. The house (2012 ICF/EIFS construction) has been cooled and heated with a 3.5 ton AC and 15 kW heatstrips respectively.
The air handler is in a mechanical room in the basement, supplying to registers in the floor of first floor and the ceiling of the basement with returns high up on the walls on first floor and near the floor on the walls in the basement.
What I am planning to do is to replace the AC/Heatstrip system with a couple of mini-splits in the basement open area and then use the current Air handler for circulation of air between the basement and the first floor. Essentially the idea is to turn the basement into an extended air handler with the heat/cold added by the mini-splits instead of the AC coil and heat strips.
Has anyone done this before and any pitfalls with this approach?
