Description

The MRCOOL® Signature Series 48k Cooling Only Condenser offers efficient, dependable cooling designed to meet the needs of modern homeowners. With a 13.8 SEER2 and 11.2 EER2 rating, this unit delivers comfort while helping lower energy bills, making it a reliable choice for both replacements and new installations.

Pre-charged with R-454B refrigerant, the unit meets current environmental standards while maintaining strong cooling capabilities. At its core is a reliable scroll compressor, supported by inner-groove copper tubing for efficient heat exchange and improved thermal conductivity.

Though powerful, the system operates quietly at 65 decibels, about as loud as a dishwasher or normal conversation, making it ideal for residential settings. A sound-dampening top further reduces operating noise. Steel louver coil guard and wire fan discharge grille protect internal components from debris, impacts, and harsh weather.

Compact in size and equipped with user-friendly service features like sweat connection valves and a convenient gauge port, installation and maintenance are straightforward. Backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, the MRCOOL® Signature Series 48k Cooling Only Condenser is a strong, smart choice for year-round cooling comfort.
