Description
The MRCOOL Universal Series MDPH18060D is a 5-ton DC inverter heat pump package unit running low-GWP R-32 refrigerant. It reaches up to 18 SEER2, modulates its inverter compressor to match the load, and keeps heating down to -22°F outdoor temperature — a self-contained, all-electric system for homes that want cold-climate heat pump performance without a split system.
The MRCOOL® 2nd Generation Universal® Series 60K Inverter Packaged Heat Pump is an advanced all-in-one solution designed to provide reliable comfort, lower energy costs, and environmentally responsible performance. With its inverter-driven compressor, the system operates at variable speeds, constantly adjusting to the heating and cooling demands of your home.
This ensures steadier temperatures, reduced energy use, quieter operation, and less wear on the unit compared to traditional systems that frequently cycle on and off. Rated at a SEER2 of 18, this heat pump significantly improves efficiency and helps cut monthly utility bills while maintaining strong performance and consistent airflow. It is built for extreme weather, capable of heating in conditions as low as –22°F (–30°C) and cooling in temperatures up to 125°F (52°C).
This wide operating range makes it a dependable option in virtually any climate. The system uses R-32 refrigerant, a modern, lower-GWP choice that reduces environmental impact while meeting today’s ecological standards. By selecting this refrigerant, MRCOOL® combines sustainability with the powerful performance homeowners expect. Installation is simplified thanks to a flexible multi-position design that supports downflow and horizontal applications.
Engineered for durability and year-round operation, the Universal® 60K is backed by a 10-year parts and labor warranty, giving homeowners confidence in long-term reliability. It is an efficient, eco-friendly, and versatile investment in lasting comfort. Find the Brochure HERE
