What Deming code requires
Installing or replacing an HVAC system in Deming follows New Mexico 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 minimum14.3 SEER2 (Southwest, <45k BTU)
Federal Southwest-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—
Hot-dry climate means many homes run evaporative (swamp) coolers; swamp-cooler-to-refrigerated-air conversions are common and need a CID/local AHJ mechanical permit. Southwest region also carries an EER2 minimum on new ACs.
