Furnaces & boilers in East Hampton: what's different here
Shingle-style and Colonial Revival houses under the village elms, oceanfront estates on the lanes south of the highway, and mid-century and new-build houses in Springs and Northwest Woods, many of the older ones on boilers with no ductwork upstairs.
East Hampton splits between the open, salt-exposed side and the wooded inland side, and the fuel question splits by street: some roads have a gas main and most do not. The contractor’s first job is to establish what reaches the house, then to size the new equipment with a Manual J calculation rather than by copying the nameplate on the old one.
In the historic parts of East Hampton, a new flue termination or exterior tank visible from the street may need review; the contractor should raise it before ordering.
The village's four historic districts (Huntting Lane, Main Street, Ocean Avenue, The Hook) are overseen by the Design Review Board; check with the board before putting a condenser or mini-split head on a street-facing elevation. Town of East Hampton building permits have been running far behind the 15-day statutory clock; a 2026 report put the backlog at 16–20 weeks. Like-for-like equipment swaps usually avoid a full permit, but confirm before any job that adds ductwork or changes structure.
Permits in East Hampton run through the Village of East Hampton Building Department inside the village; Town of East Hampton Building Department for Springs, Northwest Woods and the rest of the town; the HVAC contractor we put you in touch with handles the filing where one is required.

FAQ
Furnaces & boilers questions
Are heat pumps a good idea in the Hamptons?
Often, yes, with the numbers done honestly. Winters here are mild for heat-pump purposes: design temperatures are 11.9°F (Westhampton) to 15.7°F (Islip), and a listed cold-climate unit holds capacity at 5°F. The live incentive is PSEG Long Island's Home Comfort Plus rebate, a flat $4,000 at market rate and $5,000–7,500 income-qualified, through December 31, 2026; the federal 25C credit ended for systems placed in service after December 31, 2025. On running cost, at Long Island's 27–28¢ per kWh a heat pump beats oil only when oil is above roughly $3.90 a gallon, which it was for most of the past year ($3.67–6.01). It also cools. Budget $16,000–22,000 before rebates for a ducted conversion in a 2,000 sq ft house.
Read the full answer →How often should I service my HVAC system?
Twice a year: a cooling visit in spring and a heating visit in fall, at $60–200 for an AC tune-up and $70–200 for a furnace or boiler (most homeowners $100–150 per visit), or $150–350 a year for a plan that bundles both with priority scheduling. Near the ocean, add a low-pressure rinse of the outdoor coil: trade guidance says 2–4 times a year oceanfront and 1–2 inland, never with a pressure washer. If the house closes for the winter, make the fall visit the shutdown visit: thermostat set to keep the house at or above 55°F (what most policies expect), water shut off and drained if not, filters fresh, and a Wi-Fi temperature alarm (from about $25) reporting to you and to someone local.
