Description

The MRCOOL® 2nd Generation Universal® Series 48K Inverter Packaged Heat Pump delivers efficient, dependable heating and cooling in a comprehensive system designed for year-round comfort.
Built with advanced DC inverter technology, the compressor operates at variable speeds, adjusting output in real time to meet your home’s exact demands. This design reduces wasted energy, extends system life by minimizing wear, and keeping noise levels low.
With a strong 18 SEER2 efficiency rating, the Universal® 48K helps lower utility bills while maintaining powerful airflow and consistent performance. It is engineered to handle extreme climates, providing heat in temperatures as low as –22°F (–30°C) and cooling in conditions as high as 125°F (52°C). No matter the weather, homeowners can rely on this system to keep indoor spaces comfortable.
The use of R-32 refrigerant makes this model more environmentally responsible than systems using older refrigerants. With a lower Global Warming Potential, R-32 aligns with modern ecological standards and supports sustainable home upgrades.
Installation flexibility is another benefit with a design that allows for vertical upflow/downflow and horizontal setup. This adaptability makes the Universal® 48K ideal for both replacement projects and new installations.
Durability and reliability are built in, with rugged construction to withstand year-round operation. Backed by a 10-year parts and labor warranty, the MRCOOL® Universal® Series 48K provides lasting value, comfort, and peace of mind for homeowners
