Heating & Cooling

Comfort that holds up through Long Island summers and winters

EPA 608 certified technicians install and service ductless mini-splits, central air, furnaces, and boilers, with equipment sized to the building instead of guessed at.

Ductless & HVAC equipment

We install, warranty-service, and stock parts for the ductless and HVAC lines we carry — which means faster repairs and equipment we know inside out.

Ductless Mini-Splits

Zoned heating and cooling for additions, attics, sunrooms, and older homes with no ductwork — quiet, efficient, and individually controlled.

Central Air

Repair, replacement, and full system design with proper load calculation so the equipment matches the house instead of guessing at tonnage.

Furnaces & Boilers

Gas and oil heating repair, tune-ups, and high-efficiency replacements — including steam and hot water boiler work common in Long Island homes.

Maintenance Plans

Spring cooling and fall heating tune-ups that catch failing capacitors, weak igniters, and low refrigerant before a heat wave or cold snap does.

Indoor Air Quality

Media filtration, whole-home humidification and dehumidification, UV treatment, and ventilation for allergy and mold-prone spaces.

Commercial HVAC

Rooftop units and split systems for restaurants, retail, and offices, with preventive maintenance scheduled around your business hours.

Why ductless

Fix the room that's always too hot

Long Island housing stock is full of finished basements, converted attics, and additions that were never on the duct plan. A mini-split solves that room without tearing open ceilings.

  • No ductwork — line set runs through a 3-inch wall penetration
  • Independent temperature control for each zone
  • Heats efficiently well into Long Island winter temperatures
  • Dramatically quieter than a window unit, indoors and out
  • Qualifying installations covered by our 2-Year Labor Warranty
