See detailsIs this a real load calculation?
No. It gives a planning range based on your inputs. A real load calculation measures your home on site and accounts for details this tool cannot see.
Why not just use square footage?
Square footage ignores insulation, windows, sun and air leakage, so two homes the same size can need very different systems.
Can a system be too big?
Yes. Oversized systems short cycle, wear out sooner and handle humidity poorly.
