Where to Buy Carrier

Packaged rooftop units (RTUs) are self-contained HVAC systems that combine cooling, heating, and air-handling components in a single roof-mounted enclosure. They provide conditioned air to commercial buildings such as retail, offices, and schools, connecting to ductwork through the roof curb.

Split systems are HVAC configurations with a separate outdoor condensing unit and indoor evaporator/air-handling unit connected by refrigerant lines. They provide cooling and, with heat pumps, heating for zones in commercial buildings such as offices, server rooms, and tenant spaces.

Central plant equipment that removes heat from a liquid, typically water or a glycol solution, for distribution to air handling and cooling systems. Used in commercial HVAC to provide cooling for large buildings, available in air-cooled and water-cooled configurations using centrifugal, screw, or scroll compressors.

Factory-assembled HVAC units containing fans, heating and cooling coils, filters, and dampers that condition and circulate air through ductwork. Used in commercial buildings to provide ventilation, heating, and cooling to occupied spaces.

Fan coil units are terminal HVAC devices containing a fan and one or more heating/cooling coils that condition air within a zone. They are used in hotels, multifamily buildings, offices, and healthcare facilities to provide localized heating and cooling from central hot- and chilled-water systems.

Variable refrigerant flow heating and cooling systems that modulate refrigerant to multiple indoor units from a common outdoor condenser. Used in commercial buildings for zoned climate control with high part-load efficiency.

Variable air volume boxes that modulate conditioned airflow to individual zones, often with reheat coils and controls. Used in commercial HVAC systems to maintain zone temperature and optimize energy use.
