MRCOOL® VersaPro® 4-Ton Package Heat Pump 13.4 SEER2 (46,500 BTU Cooling & 46,000 BTU Heating) R-454B — MPH481HO13C

Product Description 

The MRCOOL® VersaPro® MPH481HO13C Package Heat Pump is a 4-ton, high-capacity all-in-one HVAC solution designed to deliver powerful, dependable heating and cooling from a single outdoor unit. Built for homeowners upgrading from older systems or installers looking for a clean, efficient packaged replacement, this system provides strong performance in both extreme summer heat and cold winter conditions.

 

With a 13.4 SEER2 efficiency rating, the VersaPro® 48K is engineered to lower energy consumption without sacrificing comfort. The system operates using R-454B refrigerant, a next-generation, low-GWP refrigerant that meets current and future environmental standards—making it a smart, compliant choice for modern HVAC installations.

 

Durability is built into every component. A power-painted galvanized steel cabinet shields the system from corrosion, moisture, and outdoor wear, while the horizontal discharge design helps reduce operating noise—ideal for residential neighborhoods. Inside the cabinet, aluminum tubing and fin coils provide excellent heat transfer and superior corrosion resistance compared to copper, reducing long-term maintenance and extending service life.

 

At the core of the system, a high-efficiency scroll compressor works in conjunction with an ECM condenser fan motor and a PSC indoor blower motor to deliver smooth airflow, balanced temperature control, and reliable operation. Integrated safety controls continuously monitor pressure levels and coil temperatures to ensure stable performance under demanding conditions.

 

Backed by industry-leading warranties, the MRCOOL® VersaPro® MPH481HO13C is a long-term investment in comfort, efficiency, and peace of mind.
