Panasonic CS-HM24BAAU1 INTERIOS 1.5 Ton A-Coil Heat Pump

Product Description

The Panasonic INTERIOS CS-HM24BAAU1 is a multi-position A-coil indoor unit designed for hybrid heating and cooling applications. When paired with the CU-HM18BAHU outdoor Extreme Heat Pump, it forms a 1.5-ton dual-fuel heat pump system that integrates with a new or existing furnace for whole-home heating and cooling. The system uses R454B refrigerant and is designed for cold-climate operation down to -22°F.
