What we handle
Central systems, basements and attics
Long Island repair calls look different from the city. Most houses in Nassau and western Suffolk have a furnace or air handler in the basement, attic or garage, ductwork to every room and a condenser beside the house. So the common calls are a central AC that runs but will not cool, an attic air handler leaking through a ceiling, a furnace that locks out on a cold night, or a heat pump stuck in defrost.
Because we are based in Roosevelt, Long Island visits are close to home. We check the thermostat, the equipment, the filter, the drain and the airflow, then quote the repair in writing before starting.
Work is limited to residential, light-commercial and PTAC equipment we repair ourselves, plus unit-level radiators and valves. Building boiler rooms and central plant equipment are not part of our scope.
Furnace & heat pump repair
Ignition lockouts, short-cycling, defrost problems and blower failures.
Attic & basement air handlers
Overflowing drain pans, ceiling leaks, failed condensate pumps and weak airflow.
Navien tankless boilers
Error codes, no heat, no hot water and ignition faults on Navien equipment.
Local service guidance
Before you call: Long Island central systems
Check the thermostat batteries and mode, the breaker for both the indoor and outdoor units, and the furnace or air-handler filter. A clogged filter is a common cause of no-cool and frozen-coil problems, and checking it takes two minutes.
If water is coming through a ceiling under an attic air handler, switch the system off at the thermostat and the service switch, then call. The drain pan or condensate line is usually blocked, and running the system adds water to the ceiling.
