## Long Island Climate Considerations
- **Climate Zone 4A** — humid continental, moderate winters with cold-air spells.
- **Coastal salt air** affects condensers in Wantagh, Massapequa, Seaford — we install corrosion-resistant outdoor units.
- **Aging Levitt-era housing stock** in Levittown/Hicksville often runs on undersized 1950s ductwork and converted oil systems.
- **Ductless retrofits** are popular in capes and split-levels where installing full ductwork isn't practical.
