The DP14HM packaged heat pump has an energy-efficient compressor that provides best performance. Single-stage heating and cooling (two-stage for the 5-ton model), a multi-speed ECM blower motor, and an all-aluminum evaporator coil are just a few features that come stock with this 14 SEER heat pump system. The heavy-gauged galvanized-steel cabinet with two-tone Nickel gray powder-paint finish makes this unit very attractive. The cabinet also comes with a factory-installed compressor sound blanket that offers excellent noise dampening.
