HVAC services
HVAC Repair
Diagnosis and repair of central AC, heat pumps, mini-splits, furnaces and boilers by a local contractor who will tell you plainly when a repair is throwing good money after bad.
Heat Pump Installation
Ducted and dual-fuel heat pumps that carry a South Fork winter, priced against 2026 ranges, with the rebate that is live (PSEG Long Island Home Comfort Plus) and the tax credit that is not.
Ductless Mini-Split Installation
Single- and multi-zone ductless systems for the rooms central air never reached: 2026 cost per zone, brand tiers, cold-climate heating, salt-air placement, and how long the install takes.
Central AC Replacement
A new condenser and coil, or a whole system, sized by a Manual J load calculation and specified for salt air. Published 2026 cost ranges by efficiency tier, the refrigerant change, and what to ask about ductwork.
Furnace & Boiler Replacement
Replacing an oil or gas boiler or furnace, converting off oil, and what the 2026 rules (the 90% AFUE minimum, the furnace and refrigerant litigation, the new-construction gas law) mean for an existing house.
Tune-Ups & Maintenance Plans
Spring cooling and fall heating checks, salt-air coil care and a plan for the months nobody is home: what a proper tune-up includes, what it costs, and what a service agreement is worth.

FAQ
Common questions
How much does HVAC repair cost in the Hamptons?
Expect a $75–250 diagnostic visit (typically $89–149; $125–400 after hours or on a weekend), then the part. National 2026 ranges: capacitor $80–400, contactor $200–450, condenser fan motor $300–700, blower motor $450–2,000, control board $300–1,400, furnace ignitor $100–250, inducer motor $400–1,100, boiler circulator pump $300–1,100. The big-ticket repairs are refrigerant leaks ($250–1,200 for a small one, $1,200–4,000 with a new coil or line set), evaporator coils ($2,500–4,500+ out of warranty) and compressors ($1,100–4,650 out of warranty). Metro-area labor, which includes Long Island, tends to sit at the top of those ranges. On equipment past its typical life (central AC 12–17 years, heat pump 10–15), a major repair is usually money that belongs in a replacement.
Read the full answer →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 →Mini-splits or central AC for a Hamptons house?
If the house has sound ductwork, replace the central system: $3,500–7,500 for standard efficiency, $8,000–12,000 for high efficiency (national 2026), about a day of work. If it has no ducts, or a wing or floor the central system never reaches, go ductless: $2,000–8,000 for a single zone and $5,000–12,000 for 2–4 zones, half a day to 3 days of work. Many Hamptons houses end up with both: central air on the main floors, mini-splits in the attic, the addition and the pool house. Mini-splits also heat, which makes them the cheapest way to keep an empty house above the 55°F most insurance policies expect in winter.
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.
How long does an HVAC system last near the ocean?
Typical lives: central AC 12–17 years, air-source heat pump 10–15, ductless mini-split 15–20, gas furnace 15–20, oil boiler 20–35. Salt air shortens the outdoor half of that. Trade sources from other coastal markets claim an unprotected condenser within sight of the surf can fail in as little as 3–5 years and a unit 1–5 miles inland in 5–8 years without protection; we have not found a Hamptons-specific study, so treat those as warnings rather than measurements. What demonstrably helps: a salt-spray-rated or coated coil (some come at no extra cost on the right model), the unit raised at least 12 inches off grade, and a low-pressure rinse 2–4 times a year. The indoor equipment, boiler, furnace, air handler, lives its normal life.
How does South Fork Air Co. work, and what does it cost me?
It costs homeowners nothing. You tell us about the job once, roughly sixty seconds: where the house is, what is going on, and when you want it handled. We put you in touch with one licensed, insured HVAC contractor who works your town and is right for your kind of system, and they call you within one business day to look at it and quote it directly. We are a Hamptons-only referral service, not a heating or air-conditioning contractor: one contractor, and nobody else gets your number. Participating contractors pay us a referral fee.
