See what needs an explanation before you sign. Separate named project scope, screen the remaining amount per nominal ton, and leave with specific questions for the installer.
Quick answer
This tool compares the equipment and installation portion of a quote with a broad scope-adjusted price-per-ton editorial screen. It is not an appraisal or market fact, and it never replaces Manual J, equipment selection, or a contractor's written design basis.

Quote inputs
Enter the total before rebates, then separate electrical and duct work. The screen compares the remaining equipment and installation amount per nominal ton.
Method
Start with the total project amount before rebates. Subtract only named electrical and duct or distribution work. Divide the remaining equipment and installation amount by nominal tonnage. The claimed rebate stays visible but does not change the screen.
Scope-adjusted price per ton = (total project amount - named electrical work - named duct or distribution work) ÷ nominal tons
The ranges below preserve the site's existing broad installed-cost bands as 3-ton editorial baselines, then normalize them per ton. They are intentionally wide. Zones and backup heat do not change the math behind the scenes. They add questions because their cost and design implications depend on the actual home and equipment.
These are editorial guardrails, not statistical confidence bands or appraisal rules.

FAQ
No. This calculator screens quote structure and price. A qualified contractor should perform or document a Manual J load calculation, then select equipment using its capacity at the local design temperature.
No. It means the scope-adjusted price per nominal ton sits inside a broad editorial range. Model selection, low-temperature capacity, installation quality, warranty, controls, ducts, electrical work, and backup heat still need review.
Those costs are part of the total project, but they can vary sharply by home. Naming them prevents a real panel or distribution project from being hidden inside an equipment-price comparison.
The editorial screen is normalized from broad 3-ton baseline totals. Dividing the scope-adjusted amount by entered tonnage makes a 2-ton and 4-ton project with the same total screen differently.
The claimed rebate is shown separately and does not lower the amount used for the price screen. Verify the program name, effective date, eligibility, and who receives the money before treating it as real.
