What Cottage Grove code requires

- 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.

AC Maintenance in Cottage Grove, explained.
What Affects AC Maintenance Costs in Cottage Grove?
Prices vary based on system age, refrigerant type, and permit requirements. Older systems (median home built 1988) may need more labor for coil cleaning or refrigerant checks. The shift to R-454B or R-32 refrigerant adds complexity. Permit fees and the need for a licensed gas fitter for gas-line work also influence costs. Federal 25C tax credits (30% up to $600 for high-efficiency AC) can offset expenses.
Common AC Issues Found During Tune-Ups

Evaporator and condenser coils accumulate dirt, reducing efficiency and airflow. Cleaning costs $100–$400.
Refrigerant Leaks
Older R-410A systems may leak; newer R-454B/R-32 systems require proper handling. Leak repair adds cost.
