MRCOOL Universal R32 DC Inverter 48K BTU 4 Ton 18 SEER2 Single Phase Packaged Heat Pump, MDPH18048D
Overview
```The MRCOOL® 2nd Generation Universal® Series 48K DC Inverter Packaged Heat Pump is an all-in-one ducted heating and cooling system built for efficient year-round comfort. With advanced DC inverter technology, the compressor can vary output in real time to better match demand, helping reduce wasted energy, minimize temperature swings, lower operating noise, and reduce wear from frequent start-stop cycling.
Rated at 18 SEER2, this 4 ton packaged heat pump is designed to deliver strong airflow and dependable comfort while helping manage utility costs. It is built for challenging climates, with heating operation down to -22°F and cooling performance described for high outdoor temperatures up to 125°F.
This Universal® packaged system uses R-32 refrigerant, a lower-GWP refrigerant compared with many older refrigerants. It also supports flexible installation layouts, including vertical upflow/downflow and horizontal setup, making it a strong option for both replacement projects and new installations.
