Environmentally Responsible
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.
