Location of supply ducts (ceiling or floor) depends on whether it’s a heating or cooling climate
Can someone confirm what I’ve been told about locating the supply registers? We’re going to build in the North Atlanta metro area in zone3, primarily heating climate. I was told that in a primarily heating climate, the best location of the supply registers is close to the floor. While in a primarily cooling climate, the best location is the ceiling.
I’m asking since we plan on building on a conditioned crawlspace and I plan on locating the mechanical there. So easy access to the main floor and I don’t need to plan for any duct chases up to the attic and any distribution ducting up there. I was planning on doing a conditioned attic but I want the option of doing a vented attic to lower the cost of the insulation up there.
PS, this is a single story modern Farmhouse design with a central vaulted area along with side sheds. No easy connection between the attic area’s above the side sheds. I do plan on having small duct chases up to the attic to run the ventilation ducts.
Anyways, I’ve not really found anything that confirms what I’ve been told about location of the supply registers based on heating/cooling climate.
