Which do I need?
Most projects need two or three.
For a replacement, a Manual J makes sure the new system is sized properly and Manual S matches the equipment to it. On any new system we recommend Manual D so every room gets the air it needs. Energy calculations vary by state and county. Commercial projects start with Manual N.
