Hisense ar-24u3r25u Packaged Heat Pump 18.5 SEER2 2 Ton R-32

Product Description

The HISENSE ar-24u3r25u is a single-packaged heat pump designed for residential and light commercial applications requiring both heating and cooling from a single self-contained unit. Rated at 24,000 BTU/h (2 nominal tons), it delivers up to 18.5 SEER2, 11 EER2, and 8.5 HSPF2, meeting Energy Star qualification standards. The unit operates on single-phase 208/230-volt power and uses R-32 refrigerant, a lower global warming potential alternative to R-410A. Horizontal and downflow configurations give installers flexibility on jobsites where ductwork orientation varies. Licensed HVAC technicians handle installation, commissioning, and refrigerant work on this equipment.

The ar-24u3r25u suits residential replacement projects and new construction where a rooftop or ground-level packaged unit is specified. Its wide operating range supports heating down to -4 degrees F and cooling up to 125 degrees F ambient, making it viable in climates with temperature extremes. External static pressure capability of up to 0.8 inches WC accommodates modest duct systems. The unit connects directly to any standard 24-volt thermostat, including Nest, Ecobee, and Honeywell models, without requiring an adapter, simplifying thermostat integration on retrofit jobs.

Compatibility

Compatible with standard 24-volt thermostats including Nest, Ecobee, and Honeywell models without an adapter. Designed as a self-contained packaged heat pump replacement or new-installation unit for single-phase 208/230-volt electrical services.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification for R-32 refrigerant handling. Disconnect and lock out all electrical power before servicing. Refer to local mechanical and electrical codes, including NEC requirements for minimum circuit ampacity and maximum overcurrent protection, before wiring. Verify that the existing duct system and structural support can accommodate the unit dimensions and weight prior to placement.
