HVAC Installation Cost Calculator

Price a complete HVAC scope independently from furnace replacement or heat-pump-only tools by combining equipment type, capacity, ductwork, controls, and job-closeout work.

Enter the planned system amount.

System type

System type

A full split system includes matched heating and cooling equipment.

Capacity

Capacity

Capacity should come from a load calculation, not floor area alone.

Ductwork scope

Ductwork scope

Duct leakage, sizing, and access often change real installation pricing.

Controls

Controls

Zoning is a substantial controls and damper scope, not just a thermostat.

Your state

Your state

Scales U.S.-average labor and material midpoints for typical state-level pricing. It is not an on-site bid.

How to use this calculator

  1. Enter the systems.
  2. Choose each scope driver to reflect your project.
  3. Select your state for cost scaling.
  4. Review the itemized components before requesting bids.

Results explained

This model uses separate construction components rather than a single blanket rate. The band reflects common variation in access, design, and contractor pricing.

Quick reference: HVAC Installation Cost cost drivers

Installed U.S.-average midpoints before the selected state adjustment.

ScopeMidpoint
2-ton AC-only$6,500
3-ton heat pump$11,500
3-ton full split$15,000
Major duct replacement$9,000

These are planning midpoints, not a site inspection, engineering opinion, or contractor proposal.

How the estimate is built

Equipment is the central itemized line, with capacity, ductwork, controls, and permit/haul allowances kept separate for a clearer installed budget.

Example scenario

A 3-ton heat pump with minor duct work and a smart thermostat models near $15,000 at U.S. average.

FAQ

Is tonnage the same as BTU?

One cooling ton is roughly 12,000 BTU per hour, but system selection needs a proper load calculation.

Does this replace refrigerant lines?

The minor and major duct choices do not fully define line-set replacement; confirm it in a quote.

Are rebates included?

No. Incentives vary by utility, income, equipment efficiency, and program timing.
