Recommended unit for Castle Pines

What Castle Pines code requires
Installing or replacing an HVAC system in Castle Pines 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.
