Description
The MRCOOL VersaPro MPH361HO13C is a 3-ton (36,000 BTU) horizontal heat pump package unit using R-454B refrigerant and rated at 13.4 SEER2, 11.2 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 36K Package Heat Pump delivers reliable, year-round comfort in a space-saving system. Designed for both powerful summer cooling and dependable winter heating, it offers an ideal combination of performance, efficiency, and durability—making it a strong choice for homeowners upgrading from older HVAC systems. With a 13.4 SEER2 rating, the VersaPro® 36K reduces energy usage and lowers monthly utility costs without sacrificing capacity.
It uses R-454B refrigerant, a next-generation option with a much lower global warming potential than older refrigerants, supporting eco-conscious upgrades while maintaining high performance. Durability is built in with a power-painted galvanized steel cabinet that protects against weather, rust, and wear. The horizontal discharge design ensures quiet operation, ideal for residential neighborhoods.
Inside, aluminum tubing and fin coils improve heat transfer and resist corrosion better than copper, reducing maintenance and extending service life. A high-efficiency full series compressor paired with an ECM blower motor provides precise airflow control, consistent temperature regulation, and reduced energy use. Built-in safeguards protect against pressure extremes and coil temperature fluctuations.
When registered, the unit comes with a 10-year limited parts warranty and a 10-year compressor warranty, making the MRCOOL® VersaPro® 36K Package Heat Pump a smart, long-term investment in comfort, energy savings, and dependable performance. Find the Brochure HERE
