Hisense ao-12u3r25e Ductless Outdoor Unit 12000 Btu/h

Product Description

The HISENSE ao-12u3r25e is a single-zone ductless outdoor condensing unit from the Hi-Edge series, designed for residential and light-commercial mini-split applications. Operating on 208-230V power and using R32 refrigerant, this unit pairs with a compatible indoor air handler to deliver targeted heating and cooling without the need for ductwork. The R32 refrigerant charge offers a lower global warming potential compared to R410A. Licensed HVAC technicians handle the installation and commissioning of this outdoor unit.

The ao-12u3r25e is suited for single-zone applications such as individual rooms, additions, garages, or server spaces where independent temperature control is required. As part of the Hi-Edge series, the unit is engineered for wall-mounted or ground-level outdoor installation and connects to a matching HISENSE indoor unit via refrigerant lineset and low-voltage control wiring. This configuration eliminates duct losses and allows zone-level setpoint control.
