MRCOOL® Signature Series 24k Cooling Only Condenser
The MRCOOL® Signature Series 24k Cooling Only Condenser offers dependable, energy-efficient performance for homeowners looking to upgrade their comfort without increasing energy bills. With a 14.3 SEER2 and 11.7 EER2 rating, this system delivers consistent, cost-effective cooling for a wide range of residential applications.

R-454B Refrigerant
This unit comes factory pre-charged with R-454B refrigerant, a next-generation, low-GWP refrigerant developed to comply with today’s stricter environmental regulations. At the heart of this high-performing unit is a durable single-speed scroll compressor, engineered to provide long-lasting, reliable operation. Scroll compressors are widely known for their quiet, efficient performance and reduced mechanical wear, making them a superior choice for residential HVAC systems.

Enhance Efficiency
To further enhance efficiency and heat transfer capabilities, the unit features inner-groove copper tubing, increasing surface area contact, boosting refrigerant flow, and promoting faster, more effective temperature regulation throughout the system.

Quiet Operation
Despite its strength, the unit operates at only 60 decibels, quiet enough for everyday residential use. A sound-dampening top helps reduce noise, while a steel louver coil guard and wire fan discharge grille protect internal parts and extend the unit’s lifespan.

Warranty
The system is backed by the MRCOOL® guarantee, including a 10-year limited parts warranty and a limited lifetime compressor warranty, providing added assurance of long-term reliability.
