A ductless mini split is a heating and cooling system that conditions individual rooms or zones without any ductwork. It connects a compact outdoor compressor unit to one or more slim indoor air handlers mounted on walls or ceilings. Because there are no ducts involved, installation is minimally invasive -- making it the ideal solution for NYC brownstones, pre-war apartments, room additions, co-ops, and older buildings where traditional central AC ductwork is not practical or affordable.
The compressor and condenser sit outside your building. It pumps refrigerant through a small 3-inch conduit that runs through your wall -- no ducts, no major construction.
Slim wall-mounted, ceiling cassette, or floor-mounted units inside each room blow conditioned air directly into the space. Multi-zone systems support up to 5 indoor units per outdoor compressor.
Each indoor unit has its own thermostat, so every room can be set to a different temperature. You only condition occupied spaces, which cuts energy waste significantly.
Ideal for NYC buildings without existing ducts. Installation requires only a small 3-inch hole in the wall -- no ceilings torn up, no major construction, no weeks of disruption.
Set different temperatures in different rooms. Bedroom cooler, living room warmer -- each person controls their own zone from a remote or smartphone app.
Mini splits are among the most energy-efficient HVAC systems available. Variable-speed compressors adjust output to match demand, using only the energy actually needed.
Most mini splits are heat pumps that provide both cooling in summer and heating in winter. One system replaces your window AC and space heater -- saving money and wall space.
Indoor units operate as quietly as 19 decibels -- far quieter than a window AC unit or forced-air system. Ideal for bedrooms, offices, and study spaces in NYC apartments.
Built-in filters capture dust, allergens, bacteria, and fine particulates -- especially important in dense NYC neighborhoods with elevated outdoor air pollution and street dust.
