What Glasgow code requires
Installing or replacing an HVAC system in Glasgow follows Delaware 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—
Delaware adopts the IMC/IRC; converting a fossil-fuel system to an all-electric heat pump typically requires BOTH a mechanical and an electrical permit in all three counties (New Castle, Kent, Sussex).
