Description
The MRCOOL VersaPro MPH481HO13C is a 4-ton (48,000 BTU) horizontal heat pump package unit using R-454B refrigerant and rated at 13.4 SEER2, 11.4 EER2 and 6.7 HSPF2. Compressor, coils, blower and controls ship in one factory-charged outdoor cabinet that connects to your ductwork through side supply and return openings, giving year-round heating and cooling without an indoor air handler.
The MRCOOL® VersaPro® Series 48K Package Heat Pump delivers powerful, high-capacity heating and cooling in one compact, durable unit. Designed for strong summer cooling and reliable winter heating, it offers a balanced combination of performance, efficiency, and long-term durability—making it an excellent upgrade for homeowners who want dependable, year-round comfort.
With a 13.4 SEER2 rating, the VersaPro® 48K helps reduce energy use while maintaining solid output, lowering monthly utility costs without sacrificing performance. It uses R-454B refrigerant, a modern, environmentally responsible option with a significantly lower global warming potential than older refrigerants. The system is built for longevity.
A power-painted galvanized steel cabinet protects against corrosion and harsh weather, while the horizontal discharge design ensures quieter operation—ideal for neighborhood installations where sound levels matter. Aluminum tubing and fin coils enhance heat transfer and resist corrosion better than copper, cutting down on maintenance and extending service life.
A high-efficiency full series compressor works with a PSC blower motor to deliver consistent airflow, better temperature regulation, and improved energy performance. Built-in safety features help protect the system from abnormal pressure and coil temperature fluctuations. When registered, the unit is backed by a 10-year limited parts warranty and a 10-year compressor warranty, giving homeowners long-term peace of mind.
The MRCOOL® VersaPro® 48K is a reliable, efficient, and durable solution for comfort that lasts year after year. Find the Brochure HERE
