About this product

The MRCOOL® Signature Series 30k Cooling Only Condenser is engineered to deliver reliable, energy-efficient cooling performance for modern homes. With a 14.3 SEER2 and 11.7 EER2 rating, this system is designed to reduce energy usage while maintaining consistent indoor comfort during the hottest months of the year. This unit comes pre-charged with R-454B refrigerant, a next-generation, low-GWP solution that aligns with modern environmental regulations while still delivering reliable, high-performance heating and cooling. The factory-charged design streamlines installation, saving both time and labor costs for contractors and homeowners alike. At its core, the system is powered by a durable scroll compressor, engineered for consistent, long-lasting performance. To enhance overall efficiency, it also incorporates inner-groove copper tubing, which improves heat transfer and supports rapid temperature regulation throughout the system. Despite its powerful capabilities, this unit operates at a remarkably quiet 63 decibels, thanks to a thoughtfully designed sound-dampening top that reduces operational noise without limiting airflow. This makes it particularly well-suited for homes in residential neighborhoods or settings where maintaining a peaceful environment is important. For added durability, the unit is equipped with a steel louver coil guard and a wire fan discharge grille, both of which provide critical protection against debris and external damage. For long-term peace of mind, this system includes a 10-year limited parts warranty and a limited lifetime compressor warranty. This MRCOOL® Signature Series 30k Cooling Only Condenser offers efficient cooling, lasting durability, and quiet comfort in a compact, easy-to-install package.
