AC Installation in Huntington, NY

All four Huntington installs from 2022 centered on a 4-ton Rheem air handler and a matching 4-ton Rheem condenser. Two were change-outs of attic units, in April and August. The other two, in April and July, put a new air handler in the basement to cool the first floor, with ductwork run fresh.

• April 2022, attic: an existing attic unit serving the first and second floors came out, and the new air handler was hung on Kindorf channel and threaded rod, then leveled.
• April 2022, basement: new air handler, condensate pan with a safety float switch, new supply and return ducts, flex runs, a central return with filter grille and a programmable digital thermostat.
• July 2022, basement: a 16 SEER system with a hot water coil mounted above the air handler, R8 insulated supply and return ductwork and new supply grilles.
• August 2022, attic: replacement of the indoor and outdoor units, with the existing drain lines reconnected and the supply and return ducts modified to meet the new cabinet.

A hot water coil lets one air handler deliver both cooling and heat. In the July 2022 basement install, we set that coil above the new 4-ton air handler so boiler water could warm the air in winter while the same blower and ducts carry cooled air all summer.

That arrangement is called hydro-air, and it suits Huntington. Plenty of houses here, from Victorians near the village to mid-century split-levels, already heat with a hydronic boiler. Adding a coil means the new duct system earns its keep twelve months a year instead of sitting idle after September. The boiler side gets checked before the coil is piped in: circulator capacity, zone wiring and a sensible tap on the supply and return piping.

Placement usually follows the existing ductwork. Huntington homes that already had attic air handlers kept them there in our 2022 jobs, while the two homes without usable duct paths for the first floor got basement units that push air up through short floor runs to the main living rooms.

An attic unit serving bedrooms sits close to the rooms that overheat most. The tradeoff is heat: a North Shore attic in July can cook the cabinet and any duct running through it, so insulated ductwork and a working secondary pan both count. For older homes with plaster walls and no route for ducts, ductless can be the gentler option; our Huntington multi-zone mini-split project replaced two old systems that way.

Every one of our Huntington installs dealt with drainage, either by fitting a new drain pan under the air handler or by running fresh primary and secondary drain lines. The April basement job also got a safety switch that shuts the system off if water backs up into the pan.

An attic air handler sheds a surprising amount of water on a humid August afternoon. If the primary line clogs with algae, the secondary pan catches the overflow, and a float switch stops the cooling before that pan spills onto a bedroom ceiling. Salt air off Huntington Harbor and Cold Spring Harbor is hard on outdoor coils too, so the new condensers went onto fresh stability pads, clear of plantings, where it can be rinsed during maintenance.

At least three of the four Huntington records list a new copper line set, and each one was pressurized with nitrogen after installation to prove it held without leaking. Only then is the system evacuated and charged, so moisture and air never sit inside the new equipment.

Reusing an old line set can work when the copper is the right size and clean, but older lines that carried a different refrigerant or were kinked during a past repair put a new compressor at risk. The old condenser is pumped down before it's disconnected, which keeps its refrigerant out of the air. After start-up we check temperatures across the coil, confirm the drain flows and walk you through the thermostat. We help register the equipment with the manufacturer afterward; see our warranty page.

Unincorporated Huntington homes go through the Town of Huntington Department of Engineering Services at 100 Main Street, while homes inside the Village of Huntington Bay use the village building department. K2 does not file permits, so please check what your installation needs with the correct office before it's scheduled.

Cost depends on whether ductwork stays, gets modified or is built new, plus attic access and line set length. We quote every install in writing after a visit; our Long Island AC installation cost guide explains what moves the number.

We also work in Huntington Station and Greenlawn.
