MRCOOL® Signature Series 42k Cooling Only Condenser
The MRCOOL® Signature Series 42k Cooling Only Condenser is built to provide reliable, energy-efficient cooling for homeowners who want dependable performance and lower utility bills. With a 14.3 SEER2 and 11.7 EER2 rating, this system offers consistent comfort while keeping energy consumption in check, making it a great fit for both replacement projects and new installations.

R-454B Refrigerant
Pre-charged with R-454B refrigerant, this unit complies with modern environmental regulations while maintaining strong cooling capacity and dependable performance.

The compact, lightweight design allows for flexible placement in tight spaces, while sweat connection valves and an easy-access gauge port make installation and maintenance straightforward.
