Description
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.
Pre-charged with R-454B refrigerant, this unit complies with modern environmental regulations while maintaining strong cooling capacity and dependable performance. At the heart of the system is a durable scroll compressor, engineered for steady, reliable operation over time with minimal wear. Inner-groove copper tubing maximizes surface area to improve thermal conductivity and heat transfer efficiency.
Despite its robust output, the system operates quietly at 65 decibels, comparable to a household dishwasher. A sound-dampening top minimizes operational noise without limiting airflow, making this unit ideal for residential areas where quiet performance is valued.
For added durability, it features a steel louver coil guard and wire fan discharge grille to protect critical internal components. 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.
Backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, the MRCOOL® Signature Series 42k Cooling Only Condenser delivers dependable protection and lasting value.
