HOW TO USE IT

How to use the HVAC Replacement Cost Calculator

  1. 1

    Choose the unit type (heat pump, furnace, AC) and its price.

  2. 2

    Enter the installation labor.

  3. 3

    Add ductwork, piping or removal costs and review the total.

THE MATH

Replacement formula

Total cost = unit + labor + extras

HVAC replacement has three costs: the unit, installation labor and extras like ductwork, line sets, removal of the old system and permits.

PRACTICAL EXAMPLE

A 3-ton heat pump

A $6,500 unit with $1,200 labor and $800 in extras gives a total of about $8,500.
