MRCOOL Signature 4 Ton up to 13.8 SEER2 48,000 BTU Split Air Conditioner

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 is built to deliver comfort while helping lower your energy bills. Whether you’re replacing an older system or installing in a new build, this condenser delivers performance you can trust.

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

Though powerful, the system is surprisingly quiet. Operating at just 65 decibels, about as loud as a dishwasher or a normal conversation, it’s ideal for residential use where noise can be a concern. A sound-dampening top reduces operating volume, while a steel louver coil guard and wire fan discharge grille further protect internal components from debris, impacts, and unruly weather conditions.

With compact sizing and user-friendly service features like sweat connection valves and a convenient gauge port, installation and maintenance are simple. MRCOOL® also includes its industry-leading 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.
