Heating, cooling, load, and equipment sizing estimates. Compare every current national default, unit cost, range, and primary driver before opening a calculator.
This span compares different project types and default quantities. It is not the cost of completing every project in the category.

The current national default scenarios in this category run from $326 to $61,770. The middle modeled typical is $7,945. Each project uses a different quantity and scope, so compare the unit-cost column before using the category span.
This hub links to 13 calculators generated from the shared baseline store. 12 publish cost breakdowns; formula-only tools are labeled separately.
No. ZIP matching changes the labor component only through the available metro or state wage factor. Material escalation remains tied to the published national index series.
No. They are deterministic planning estimates. A local proposal should define quantities, materials, labor scope, permits, removal, disposal, and exclusions.
