Panasonic CU-HM24BAHU INTERIOS 2 Ton Cold Climate Outdoor Heat Pump

Product Description

The Panasonic CU-HM24BAHU is a 2-ton cold-climate outdoor heat pump condenser designed for the INTERIOS hybrid heating and cooling system. When paired with a compatible CS-HM24BAAU1 or CS-HM24BAAU2 A-coil, it integrates with a new or existing furnace to provide whole-home heating and cooling. The system uses R454B refrigerant, inverter-driven heat pump technology, and is designed for cold-climate operation down to -20°F (-30°C).

Key Features
