Primary cost controls
- Equipment capacity and efficiency
- Ductwork or electrical changes
- Number of zones
- Climate and design load
This worksheet starts with home area to form a furnace-capacity planning scenario, then attaches the modeled equipment and installation budget. It does not perform a room-by-room Manual J load calculation or select fuel, venting, duct changes, electrical work, or combustion-air requirements. Use its capacity result to frame questions; require the installer to document the design load and chosen furnace output.
