1. What Is AC Unit Replacement Cost?

AC unit replacement cost includes the price of the new unit plus professional installation. Costs vary based on system capacity, efficiency rating, brand, and installation complexity. The average cost for a full system replacement in 2025 ranges from $11,590 to $14,100.

2. How Does The Calculator Work?

The calculator uses the AC replacement cost formula:

\[ Cost = Capacity (tons) \times \$2,000/ton + Installation (\$1,000-3,000) \]

Where:

$ Capacity $ — AC unit capacity in tons (typically 1.5-5 tons for residential)
$ \$2,000/ton $ — Average cost per ton for standard efficiency units
$ Installation $ — Professional installation costs ranging from $1,000 to $3,000

Example: A 3-ton unit with $2,000 installation = 3 × $2,000 + $2,000 = $8,000 total cost.

3. Importance Of Accurate Cost Estimation

Details: Accurate cost estimation helps homeowners budget appropriately, compare quotes from different contractors, and understand what factors influence the final price of AC replacement.

4. Using The Calculator

Tips: Enter AC capacity in tons (typically 1.5, 2, 2.5, 3, 3.5, 4, 5 tons) and installation cost based on your contractor's quote or regional averages. The average cost for a 3-ton unit is approximately $5,750.
