HVAC Replacement Cost Estimator

Estimate the total installed cost to replace a residential or light-commercial HVAC system, including equipment, labor, materials, and disposal fees.

System Type

System Capacity (Tons) 1 ton = 12,000 BTU/hr. Typical home: 1.5–5 tons.

Efficiency Rating

Ductwork Condition

Labor Cost Region

Include Permit & Inspection Fee?

Include Old Equipment Disposal?

Total Cost = Equipment Cost + Labor Cost + Ductwork Cost + Materials Cost + Permit Fee + Disposal Fee

Equipment Cost = Base Rate ($/ton) × Capacity (tons)
Base rates vary by system type and efficiency tier (e.g., standard central AC: $650/ton; ultra-high-efficiency heat pump: $1,800/ton).
Labor Cost = Labor Rate ($/ton) × Capacity × Regional Multiplier
Regional multipliers: 0.85 (rural/South) → 1.45 (CA/NY metro).
Ductwork Cost = Equipment Cost × Duct Fraction × Regional Multiplier
Duct fractions: 0% (good), 10% (minor repair), 25% (major repair), 50% (full replacement).
Materials = ($150 + $45 × Capacity) × Regional Multiplier
Covers refrigerant (R-410A/R-32), line sets, electrical connections, and misc. supplies.
Permit Fee = $250 × Regional Multiplier (if selected)
Disposal Fee = $150 × Regional Multiplier (if selected; includes refrigerant recovery)
Efficiency Payback = (High-Eff Cost − Standard Cost) ÷ Annual Energy Savings
Annual savings: ~$225/yr (high-efficiency), ~$350/yr (ultra-high-efficiency).

Equipment base costs derived from HomeAdvisor, Angi, and ACCA contractor surveys (2023–2024 USD).
Capacity sizing rule of thumb: ~400 sq ft per ton (Manual J load calculation recommended for precision).
SEER2 / AFUE ratings per DOE minimum efficiency standards effective January 2023 (DOE 10 CFR Part 430).
Regional labor multipliers based on BLS Occupational Employment Statistics for HVAC mechanics (SOC 49-9021).
Refrigerant costs reflect R-410A phase-down under AIM Act (EPA); R-32 / R-454B transition costs may vary.
Permit fees vary widely by jurisdiction ($75–$500+); $250 is a national median estimate.
Estimates do not include electrical panel upgrades, gas line modifications, or structural modifications.
Mini-split pricing assumes single-zone head units; multi-zone systems require additional line sets and heads.
Federal tax credit: 25C Energy Efficient Home Improvement Credit offers up to 30% (max $600 for AC/heat pump, $150 for furnace) for qualifying high-efficiency equipment (IRS Publication 5886).
