Overview

Product Overview

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.

Manufacturer Warranty

Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.

Professional Installation Recommended

Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us before you order.

Before You Order

Make sure it is the right size, and that you have the rest of it

Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.
