Description
The MRCOOL Signature Series MCAEAMPEF60E21AA is a 5-ton multi-position air handler for R-454B split systems, matched with Signature Series heat pump and air conditioner condensers for AHRI-rated performance. It installs upflow, downflow or horizontal to fit closets, attics and crawlspaces. An ECM blower motor moves air quietly, and an optional MRCOOL electric heat kit adds supplemental or emergency heat.
The MRCOOL® Signature Series 60k Multi-Position Air Handler is designed to deliver reliable, efficient comfort all year long. Featuring advanced R-454B refrigerant, it meets modern environmental standards while helping reduce energy use and carbon emissions without sacrificing performance. This unit’s multi-position capability allows for installation in upflow, downflow, or horizontal configurations, making it a flexible choice for any home layout.
Whether it’s placed in a utility closet, attic, or crawl space, its slim, compact design ensures a seamless fit while delivering powerful heating and cooling when paired with a compatible condenser or heat pump. Built for long-lasting performance, this unit is equipped with a galvanized steel cabinet that resists corrosion, dents, and daily wear. Its high-efficiency ECM blower motor delivers consistent, quiet airflow while helping to lower overall energy use.
Inside, copper “A” coils with aluminum fins provide excellent heat exchange and effective humidity control. Meanwhile, internal thermal insulation helps minimize condensation and thermal loss, resulting in better comfort, quieter operation, and increased energy savings. Installation is fast and simple, saving time and reducing labor costs. An air filter rack makes routine maintenance easy, and an optional electric heat kit is available to boost cold-weather performance.
This system is also compatible with most third-party smart thermostats, giving you the freedom to choose the control platform that works best for your home without proprietary limitations.
