The MRCOOL® Signature Series 60k Heat Pump Condenser is a high-capacity, energy-efficient system designed to deliver dependable heating and cooling throughout the year. With performance ratings of 14.3 SEER2 and 11.2 EER2, it provides consistent comfort while helping reduce energy use and monthly utility costs, making it a smart choice for larger residential applications.
Pre-charged with R-454B refrigerant, this unit supports eco-conscious upgrades. R-454B offers a significantly lower global warming potential compared to older refrigerants while maintaining excellent performance. The factory pre-charge also simplifies installation, cutting down on setup time and labor expenses.
The system is powered by a durable single-speed scroll compressor built for long-term reliability. Inner-groove copper tubing enhances heat transfer for greater efficiency and responsiveness. Built-in temperature and pressure sensors continuously monitor system conditions, while an intelligent defrost function ensures smooth, uninterrupted operation in colder weather by preventing frost buildup.
Despite its robust output, the Signature Series 60k runs at just 65 decibels, quiet enough for residential areas. A sound-control top minimizes noise while maintaining proper airflow. For added durability, the exterior features include a steel louver coil guard and wire fan discharge grille to protect internal components.
The compact cabinet allows for flexible installation, and service is made easier with sweat connection valves and an accessible gauge port. Backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, the MRCOOL® Signature Series 60k Heat Pump Condenser offers lasting value and reliable year-round performance.
