The MRCOOL® 4–5 Ton Pre-Charged A-Coil is a high-performance, installation-ready solution designed for compatibility with most R-454B systems using MRCOOL® No-Vac® Quick Connect® line sets or standard flare-to-sweat connections. Ideal for both retrofit projects and new installations, it works seamlessly with a variety of HVAC configurations. .(Line set sold separately) Pre-charged with environmentally friendly R-454B refrigerant, the coil meets today’s stricter environmental standards while delivering efficient and reliable heating and cooling. Its pre-charged design eliminates the need for on-site refrigerant charging, helping reduce installation time, labor, and complexity. The coil supports upflow, downflow, and horizontal airflow orientations, making it a flexible option for homes with space constraints or unique layouts. Installation is simplified with dual front drain connections, a built-in side drain pan for horizontal models, and an integrated A2L leak detection sensor for added safety. Constructed with CoolGuard® corrosion-resistant aluminum, this coil is engineered for long-lasting durability, extending system life while reducing maintenance concerns. Backed by a 10-year limited parts warranty, the MRCOOL® 4860-D Pre-Charged A-Coil offers a reliable, energy-efficient upgrade that provides consistent comfort year-round.
