The MRCOOL® Pre-Charged A-Coil is engineered to provide a fast, efficient, and eco-friendly solution for heating and cooling applications.

Designed for seamless compatibility with most R-454B systems with No-Vac® Quick Connect® line set or a flare to sweat connections—this coil is ideal for both replacements and new installations.

Pre-charged with R-454B refrigerant, this advanced system helps meet today’s stricter environmental standards. With a significantly lower Global Warming Potential than legacy refrigerants, R-454B enables an eco-conscious upgrade without sacrificing performance. The pre-charged design eliminates the need for on-site charging, reducing installation time, complexity, and labor costs for contractors and homeowners alike.

This coil supports upflow, downflow, and horizontal installations, making it highly versatile even in space-restricted environments. Dual front drains offer convenient utility connections, horizontal units feature a built-in side drain pan for easier setup, and an A2L leak detection sensor adds safety and peace of mind during installation. Durability is a core feature of the design. The coil is constructed with CoolGuard®, a corrosion-resistant, patented aluminum blend that enhances longevity and reliability in demanding conditions. Whether used in a retrofit or a new system, this coil delivers dependable performance year-round.

Backed by a 10-year limited parts warranty, the MRCOOL® Pre-Charged A-Coil is a smart choice for anyone seeking a simplified installation, improved energy efficiency, and long-term comfort—all in one rugged, space-efficient package.
