Estimates only. Figures come from Angi and HomeAdvisor cost guides (national or DC metro reference). They are not bids from this site.
Pick a system type and a data basis. Ranges come from cited public cost guides. They are estimates, not a contractor bid.
No published NoVA-specific installed-cost data. Ranges are national (or Washington, DC where noted). They are estimates, not bids from this site.
Real sizing requires a Manual J load calculation; square footage is only a rough guide (Angi: there is no direct per-square-foot requirement).
Federal 25C Energy Efficient Home Improvement Credit ended for property placed in service after Dec 31, 2025. A 2026 install gets $0 from 25C.
