HVAC Replacement Cost Calculator

Instant Cost Estimate

What will your HVAC replacement cost?

Answer the basic questions below to get a realistic installed-cost planning range. No contact information is required.

Optional: Refine the estimate by location

General U.S. estimate Uses a broader regional range so anyone can use the calculator. New Jersey home Enter your town for a tighter local planning adjustment.

1. What type of system are you replacing? System type

Select the major equipment expected to be replaced as part of one project.

2. Do you know the current cooling-system size?

Yes, I know the size Select the nominal tonnage shown on the existing equipment or proposal. No, estimate it for budgeting Use conditioned square footage to select a preliminary planning size.

Nominal cooling capacity

Final equipment capacity must be confirmed by a load calculation, airflow review and onsite evaluation.

4. Select an equipment level

Standard efficiency Single-stage or basic matched equipment. Enhanced efficiency Higher-efficiency or two-stage equipment. Premium comfort Variable-capacity or communicating equipment.

Advanced Options Add access conditions, ductwork and other project scope.

How the Estimate Works

Representative equipment and installation assumptions

The calculator uses representative matched-system equipment pricing, installed-cost factors and project-scope allowances. The general U.S. result includes a broader regional range; New Jersey users can optionally add their town for a tighter local planning adjustment.

Current benchmark examples

2.5-ton Goodman R32 AC + air handler: approximately $4,016–$4,520.
3-ton Goodman R32 heat pump + air handler: approximately $4,182–$5,333.
3-ton Goodman R32 AC + 96% gas furnace: approximately $5,474–$5,994.

What the multiplier is intended to cover

Equipment procurement and normal material.
Labor, supervision, startup and commissioning.
Overhead, insurance, vehicles, tools and warranty administration.
Reasonable contractor profit and project risk.

What can materially change the price

Actual load, airflow and matched-system requirements.
Brand, product tier, availability and manufacturer programs.
Ductwork, electrical, drainage, venting and structural conditions.
Hazardous materials, code corrections and concealed conditions.

Important limitation

This is a preliminary homeowner planning tool, not an offer, proposal or guaranteed price. HVAC costs vary by region, brand, labor market, code requirements and site conditions. New Jersey town adjustments are local planning allowances based on Central HVAC service-market assumptions. Proper equipment capacity, system compatibility and final scope require an onsite evaluation. Do not use this tool to size equipment.
