Description
The MRCOOL® Signature Series 48k Heat Pump Condenser is a high-capacity, all-season system built to deliver powerful and efficient heating and cooling year-round. With a 14.3 SEER2 and 11.2 EER2 rating, it ensures consistent indoor comfort while helping reduce energy costs.
This model comes pre-charged with R-454B refrigerant, a modern, low-GWP alternative that complies with current environmental standards. It offers reliable performance with a smaller environmental footprint. The factory charge also speeds up installation, reducing labor time for contractors and minimizing hassle for homeowners.
A heavy-duty single-speed scroll compressor sits at the heart of the system, designed to provide steady operation across a wide range of conditions. Inner-groove copper tubing improves heat exchange, boosting system efficiency. Integrated temperature and pressure sensors protect against stress from extreme temperatures, while an intelligent defrost function prevents ice buildup during colder weather.
Despite its large output, the unit operates quietly at just 65 decibels, comparable to a typical dishwasher. A specially designed sound-control top helps reduce operating noise without affecting airflow, making it a good fit for residential areas.
Built for long-term durability, the unit features a steel louver coil guard and wire fan discharge grille to protect internal components from debris and damage. With a compact design, accessible service valves, and warranty protection including a 10-year limited parts warranty and a limited lifetime compressor warranty, the MRCOOL® Signature Series 48k Heat Pump Condenser is a smart investment in year-round comfort and reliability.
