The MRCOOL® VersaPro® Series 36K Package Heat Pump delivers reliable, year-round comfort in one space-saving system. Designed for both powerful summer cooling and dependable winter heating, it offers a well-balanced combination of performance, efficiency, and durability—making it a strong choice for homeowners upgrading from older HVAC systems. With a 13.4 SEER2 efficiency 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 far lower global warming potential than older refrigerants, supporting environmentally responsible upgrades while maintaining high performance. Durability is built into every detail. The power-painted galvanized steel cabinet protects against weather, rust, and wear, while the horizontal discharge design delivers quiet operation ideal for residential neighborhoods. 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 works with an ECM blower motor for precise airflow control, consistent temperature regulation, and reduced energy use. Built-in safeguards protect against pressure extremes and coil temperature issues. Backed by a 10-year limited parts warranty and 10-year compressor warranty, the MRCOOL® VersaPro® 36K is a smart, long-term investment in comfort, energy savings, and dependable performance.
