AC installation cost by system.
Installed pricing for Farmington, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
Farmington homeowners typically pay between $3,700 and $7,500 for a like-for-like central AC installation, with higher costs for new ductwork or heat pump systems. With a median home age of 29 years, many homes may need duct modifications or upgrades to meet current SEER2 minimums.

What Farmington code requires
Installing or replacing an HVAC system in Farmington follows Minnesota rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-climate sizing matters; gas-line work on a furnace must be done by a licensed plumber/gas fitter even if a homeowner pulls the mechanical permit.
