What Johnstown code requires
Installing or replacing an HVAC system in Johnstown follows Colorado 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: at altitude with sub-zero winters, heat pumps need a low-temp (5F) rating or gas backup; high-altitude mountain towns and Xcel offer enhanced cold-climate heat pump rebates.
