The Goodman GPH15M Packaged Heat Pump provides energy-efficient cooling and heating performance in one self-contained unit. This unit uses the environmentally friendly refrigerant R-410A, which is chlorine-free to help prevent damage to the ozone layer. The GPH15M is housed in a heavy-gauge, galvanized-steel cabinet that offers a high-quality, UV-resistant powder-paint finish and allows for a ground level or rooftop mount.
