BEA 2024 RPP · released Feb 2026. Marked trade-labor rows use a weighted BLS occupational-wage and BEA regional-price adjustment when the validated public snapshot is available. Equipment is not multiplied by a local wage factor.

Moderate planning basis

Useful as a first-pass range, but one or more local or physical-scope inputs still need an onsite inspection or permit-office confirmation.

5.5% above the high end. Ask for an itemized explanation of the difference.

Address-level permit and rules check

Mechanical, electrical, fuel-gas, energy-code, refrigerant, and inspection rules are adopted by state and local authorities. A ZIP identifies a price region, not the exact authority having jurisdiction (AHJ). Confirm the project address with the city or county permit office before work.

Source periods and confidence basis
  • BEA 2024 RPP · released Feb 2026
  • The public live-data snapshot is unavailable; national ranges and the embedded BEA regional proxy remain in use.
  • ZIP matched a residential regional-price row.
  • The selected scope is within the model's ordinary residential planning envelope.

This is a consumer planning model, not a contractor bid. Taxes, permits, hidden conditions, premium equipment, and unusual access can change the final price.

01

Why this result

  • Equipment type, capacity, efficiency, and the number of indoor units change the installed scope.
  • Only labor and field-service allowances receive the displayed regional price-level adjustment.
02

What may be missing

  • Manual J load calculation
  • Exact AHRI-matched model numbers
  • Electrical, gas-line, or condensate upgrades
  • Duct leakage, balancing, controls, and labor warranty
03

Before you sign

  • Ask for a Manual J load calculation rather than accepting square-foot sizing alone.
  • Confirm who obtains mechanical, electrical, and gas permits from the address-level authority.
  • Compare model numbers, AHRI match, startup readings, warranty, exclusions, and change-order terms.
Professional quote review guide

How to compare an HVAC replacement quote

The lowest total is not necessarily the best comparable quote. Match capacity, efficiency, model numbers, installation scope, commissioning, permits, controls, warranty, and exclusions before comparing price.

Sizing evidence (Manual J)

Ask for a room-by-room or whole-home Manual J load calculation. Existing tonnage and square footage alone do not establish the correct replacement capacity.

Matched equipment & AHRI certification

Record indoor and outdoor model numbers and verify the AHRI-rated combination. Efficiency claims must apply to the exact matched system, not a broad product family.

Commissioning record

A comprehensive scope names nitrogen pressure testing, vacuum evacuation below 500 microns, subcooling/superheat charge verification, static-pressure checks, condensate testing, thermostat setup, and old equipment disposal.

Ductwork & electrical evaluation

Ensure quotes specify whether duct modifications, transition plenums, refrigerant line replacement, disconnect boxes, or electrical breaker upgrades are included.

Common questions

What this checker can—and cannot—confirm

Can a ZIP code determine an exact HVAC replacement price?

No. ZIP-linked wage and price factors improve a planning range, but equipment selection, home load, duct condition, electrical work, access, permits, warranty, and contractor overhead require address- and project-level confirmation.

Why is a high quote not automatically an overcharge?

It may include premium matched equipment, duct repair, electrical or gas upgrades, crane or attic access, permits, commissioning, a stronger labor warranty, or work excluded from the baseline model. Ask for line-itemization before judging it.

What should be written into the HVAC contract?

Exact model numbers, capacity, efficiency rating, scope, permits, startup tests, thermostat and duct work, disposal, payment schedule, change-order rules, equipment and labor warranties, and responsible parties.

How does SEER2 efficiency affect system pricing and long-term operating costs?

Higher SEER2 ratings (such as 16 to 20+ SEER2 variable-speed systems) carry higher upfront equipment costs but lower annual electricity consumption. The true financial return depends on your local climate zone, annual cooling hours, and utility electric rates.

How is heating and cooling capacity properly calculated?

Professional sizing requires an ACCA Manual J load calculation accounting for square footage, insulation levels, window orientation, ceiling heights, air leakage, and local climate extremes rather than a generic rule-of-thumb per square foot.

Is my uploaded HVAC quote PDF or contract text sent to a remote server?

No. QuoteVerity runs OCR and quote document parsing entirely in your browser using client-side WebAssembly. Your quote documents, pricing details, and personal contractor proposals are never uploaded or stored on any external server.
