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 environmentally friendly 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 to deliver steady, reliable operation over time with minimal wear. To further enhance performance, the unit is equipped with inner-groove copper tubing, which maximizes surface area and significantly improves thermal conductivity and heat transfer efficiency.
Despite its robust output, the system is designed with noise reduction in mind, operating at a low 65 decibels, comparable to the sound of a household dishwasher. A sound-dampening top minimizes operational noise without limiting airflow, making this unit ideal for installation in residential areas where quiet performance is valued. For added durability, it features a steel louver coil guard and wire fan discharge grille, which offer strong protection for critical internal components.
The unit’s compact, lightweight design makes it easy to position in tight spaces, while thoughtful service-friendly features like sweat connection valves and an easy-access gauge port streamline both installation and ongoing maintenance. To top it off, MRCOOL® offers a 10-year limited parts warranty and a limited lifetime compressor warranty, offering dependable protection and lasting value.
