Signature 2 Ton up to 14.3 SEER2 24,000 BTU Split Air Conditioner
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. This unit comes factory pre-charged with R-454B refrigerant, a next-generation, low-GWP refrigerant specifically 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, dependable operation. Scroll compressors are widely known for their quiet, efficient performance and reduced mechanical wear, making them a superior choice for residential HVAC systems. To further enhance efficiency and heat transfer capabilities, the unit features inner-groove copper tubing—a design that increases surface area contact, boosts refrigerant flow, and promotes quicker, more effective temperature regulation throughout the system. 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 help safeguard internal parts and extend the unit’s lifespan. The system is backed by the MRCOOL® guarantee, a 10-year limited parts warranty and a limited lifetime compressor warranty, offering added assurance of long-term reliability and support. Efficient, quiet, and built to last, the MRCOOL® Signature Series 24k Cooling Only Condenser is a smart choice for reliable home cooling.
