Hisense AS-18UW3SXADLG Heat Cool Outdoor Unit 18000 Btu

Product Description

The HISENSE AS-18UW3SXADLG is an 18,000 BTU/h heat-cool outdoor condensing unit rated at SEER 18 and designed for 230-volt single-phase operation. It serves as the outdoor section of a split-system installation, handling refrigerant compression and heat exchange for both cooling and heating modes. Licensed HVAC technicians install this unit as part of a matched mini-split or ducted split system. The SEER 18 efficiency rating positions it for applications where energy performance and year-round comfort conditioning are required.

This outdoor unit is suited for residential and light-commercial split-system installations requiring 18,000 BTU/h of heating and cooling capacity. It is designed to operate at 230 volts, making it compatible with standard single-phase residential electrical service. The unit handles both heating and cooling cycles, eliminating the need for a separate heating source in moderate climates. HVAC professionals pair this condenser with a compatible indoor air handler or evaporator coil to complete the system.
