What Frederick code requires
Installing or replacing an HVAC system in Frederick follows Maryland rules under the state mechanical code. Here’s what applies statewide:

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—
Strong statewide electrification push: EmPOWER Maryland requires a low-cost ($100) home energy audit to unlock the largest heat-pump/electrification rebates, and Maryland building energy code (IECC-based) increasingly favors heat pumps.
