Overview

Product Overview

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.

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.
