What a range includes
A range is built around a complete project frame: equipment, ordinary installation labor, common materials and expected local delivery conditions. It is split into equipment and scope allowances where that helps users compare bids.
What can move the number
Load, capacity, efficiency, ducts, wiring, fuel piping, access, permits, remediation, selected controls, warranties and financing can move an actual proposal outside a planning range.
Incentives and financing
We show incentives only as a route to verify, not as a universal reduction. Financing is compared by amount financed, APR, fees, term, payment and total paid—not payment alone.
