Common questions in Long Island.
My Long Island home has oil baseboard heat and central AC in the attic—can I switch that attic AC to a heat pump?
Yes. When it's time to replace your aging attic central AC, installing a cold-climate ducted heat pump in its place gives you high-efficiency summer cooling plus electric heating through the same ducts—which can cut how much heating oil you burn each winter. Ask PSEG Long Island whether rebates apply.
What protects outdoor heat pumps and AC units on the South Shore from salt air?
For homes near the Great South Bay or Long Island Sound in towns like Massapequa, Lindenhurst, Babylon, Islip, or Huntington, we specify corrosion-resistant coil designs, composite base pans, and elevated stands to protect against salt spray and snow accumulation.
Do Nassau and Suffolk County towns require permits for HVAC replacement?
Yes. Towns and villages across Nassau and Suffolk counties (such as Hempstead, Oyster Bay, North Hempstead, Huntington, Babylon, Islip, Smithtown, and Brookhaven) have specific building department and licensed contractor requirements. Our licensed Long Island partner crews handle all local compliance.
Long Island climate and homes.
Long Island climate and homes.
Long Island brings humid Atlantic summers, winter nor’easters, and salt air on both shores. Many homes heat with oil or gas baseboards and use separate attic AC or window units.
Your local weather
Nassau and Suffolk counties sit in IECC Climate Zone 4A (Mixed-Humid). Surrounded by Long Island Sound, the Great South Bay, and the Atlantic Ocean, the island experiences heavy summer dew points, corrosive coastal salt air on the South and North shores, and damp winter freezes primarily in the teens, 20s, and 30s.
Homes and ductwork
Long Island's iconic housing stock includes slab-on-grade and basement capes in Levittown, Hicksville, and Westbury; high-ranch (bi-level) and split-level homes in Syosset, Plainview, Commack, and Smithtown; and historic colonials and Tudors in Garden City, Rockville Centre, and Huntington. Many homes heat with oil or gas hydronic baseboards and rely on separate attic central AC or window units.
Utilities and rebates
PSEG Long Island (electric, with small municipal utilities in Freeport and Rockville Centre) and National Grid (natural gas, where gas mains exist). PSEG Long Island's Home Comfort program offers significant rebates for qualifying cold-climate central and ductless heat pumps.
