Figuring out the heat load for a ducted system involves calculating the total heat that needs to be removed or added to keep a space comfortable, then accounting for heat gains or losses through the ducts themselves. It's more complex than a simple room calculation because ductwork running through unconditioned spaces like attics or crawlspaces can significantly reduce system efficiency if not properly insulated. You need to factor in conduction through duct walls, air leakage, and solar radiat…
