Recommended unit for Brentwood
Given New York’s cold climate and gas heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most Brentwood homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.

What Brentwood code requires
Installing or replacing an HVAC system in Brentwood follows New York 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 calculationRequired (Manual J)
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: NY energy code (2020 NYSECC) references ACCA Manual J/S for equipment sizing, and cold-climate (ccASHP) heat pumps rated for sub-zero performance are needed in most of the state's climate zones 4-6.
