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.
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.
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.
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.
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.
