The MRCOOL® 4-5 Ton Pre-Charged A-Coil is a high-performance, installation-ready solution designed to work seamlessly with most R-454B systems that have No-Vac® Quick Connect® line set or a flare to sweat connections. It’s also compatible with a range of other HVAC configurations, making it an excellent choice for both retrofit projects and new installations. Factory pre-charged with environmentally friendly R-454B refrigerant, this coil helps meet today’s stricter environmental standards. With a significantly lower Global Warming Potential than older refrigerants, R-454B reduces environmental impact while maintaining efficient, reliable cooling and heating performance. The pre-charged design means contractors don’t need to charge the system on-site, saving time and reducing installation costs. The A-Coil supports multiple airflow orientations—upflow, downflow, and horizontal—making it a flexible option for homes with space limitations or unique layouts. Helpful features like dual front drains allow for simple condensate management, while a built-in side drain pan (for horizontal models) and an A2L leak detection sensor makes setup fast and straightforward. Engineered for durability, the coil features CoolGuard® corrosion-resistant aluminum, a patented blend designed to withstand the demands of long-term use. This added protection helps extend equipment life while reducing the likelihood of performance issues over time. With a 10-year limited parts warranty, the MRCOOL® 4860-D Pre-Charged A-Coil provides lasting value and dependable performance. It’s a smart, energy-efficient upgrade for anyone seeking an easy installation and consistent comfort, season after season.
