Description

MRCOOL Universal 48K DC Inverter Packaged Heat Pump MDPH180484

The MRCOOL Universal 48K DC Inverter Packaged Heat Pump is a high-capacity, all-electric HVAC solution designed for both residential and light commercial applications. Engineered for quiet operation and precise temperature control, this unit delivers reliable heating and cooling without relying on fossil fuels. Its 4-ton capacity provides a substantial upgrade over traditional split systems or aging gas equipment.

Equipped with advanced DC inverter technology, the system continuously modulates the compressor and fan motors. This feature ensures steadier indoor temperatures, reduces electrical consumption, and minimizes wear on components, all while operating more quietly than conventional single-stage packaged units.

With an 18 SEER2 efficiency rating, HSPF2 of 8.5, and ENERGY STAR certification, the heat pump is built to optimize energy savings and long-term operating costs. It performs reliably in extreme climates, providing cooling in temperatures up to 125°F and heating down to -22°F, making it suitable for diverse environmental conditions.

The unit also offers versatile installation options, supporting both side and bottom air return for ground-level or rooftop placements. Optional electric heat kits (5kW–20kW) can be added for auxiliary heating, while intelligent defrost technology ensures efficient winter operation. Backed by a 10-year parts, compressor, and labor warranty, this packaged heat pump provides peace of mind and long-lasting comfort.
