HVAC Replacement Cost Estimator for Utah Homes
Estimate the total cost to replace your HVAC system in Utah, including equipment, labor, permits, and disposal fees. Costs reflect Utah's climate zone requirements and current market rates.
Formula
Total Replacement Cost = Equipment Cost + Labor Cost + Ductwork Cost + Refrigerant & Misc + Disposal + Permit Fees
- Required Tonnage: (Square Footage × BTU/sq ft) ÷ 12,000 — where BTU/sq ft = 480 (southern UT) to 600 (mountain areas), rounded to nearest 0.5 ton
- Equipment Cost: Base cost by system type + (Tons × per-ton rate) × SEER2 efficiency premium (1.00–1.50×)
- SEER2 Premium: 14.3 SEER2 = 1.00×, 16 SEER2 = 1.15×, 18 SEER2 = 1.30×, 20+ SEER2 = 1.50×
- Labor Cost: Labor Hours × $95/hr × Regional Multiplier — hours vary by system complexity (6–16 hrs) plus age surcharge
- Ductwork Cost: Square Footage × $/sq ft rate (0 for good condition, $0.50 minor, $1.50 major, $3.00 full replacement, $4.50 new install) × Regional Multiplier
- Regional Multiplier: 0.93 (rural) to 1.05 (Park City/high altitude)
- Federal IRA Tax Credit: 30% of equipment cost, capped at $2,000 (heat pumps) or $600–$1,200 (AC/furnace)
