Product Overview
The MRCOOL® 2.5-3 Ton Pre-Charged A-Coil is built to simplify installation and deliver dependable comfort for a wide range of HVAC applications. Designed to pair perfectly with most R-454B systems with No-Vac® Quick Connect® line set or a flare to sweat connections—this coil is an ideal choice for both retrofit projects and new setups. Pre-charged with environmentally friendly R-454B refrigerant, this coil meets today’s climate-conscious standards. R-454B offers a significantly lower Global Warming Potential than older refrigerants, helping reduce your home’s environmental impact without sacrificing performance. The factory charge also eliminates the need for field-charging, cutting down on installation time, labor costs, and complexity. Compact and adaptable, the MRCOOL Pre-Charged A-Coil supports upflow, downflow, and horizontal applications, making it easy to install in tight or unconventional spaces. It features dual front drains for flexible utility connections, built-in side drain pan for horizontal configurations, and an A2L leak detection sensor as an additional safety measure—each detail is designed with homeowner and contractor convenience in mind. Constructed with CoolGuard® corrosion-resistant aluminum, the coil is engineered for long-lasting performance, even in tough operating conditions. Its durable build helps extend system life and reduce maintenance needs over time. Backed by a 10-year limited parts warranty, the MRCOOL® 3036-B Pre-Charged A-Coil offers homeowners and contractors a reliable, energy-efficient solution that delivers season after season. It’s the smart way to upgrade your system while saving time, energy, and installation effort.
