Methodology, assumptions & sources
How this estimate is calculated
Installed system type establishes the base range. Equipment tier, ductwork, and thermostat are separate allowances; home size is a context cross-check only.
This is a planning estimate, not a contractor quote. Actual quotes vary by location, specification, site conditions, labour, and project requirements.
Included assumptions & exclusions
- Final HVAC sizing should be based on a professional load calculation.
- Equipment tier adjustments are HomeCostNest planning assumptions, not national averages.
- Permits are not included and vary by jurisdiction.
