MRCOOL® Signature 2 Ton 24K BTU Split System Multi-Position Air Handler, MCAEAMPSF24C21AA

Product Description 

MRCOOL® Signature Series 24,000 BTU Multi-Position Air Handler

The MRCOOL® Signature Series 24k Multi-Position Air Handler (MCAEAMPSF24C21AA) is designed to deliver dependable comfort, flexible installation, and long-term reliability for residential HVAC systems using modern R-454B refrigerant.

Built to support upflow, downflow, or horizontal installation, this air handler adapts easily to a wide range of home layouts, including closets, attics, and crawl spaces. Its compact footprint makes it an excellent option where space is limited, while still providing the airflow needed to properly support a 2-ton system when paired with a compatible MRCOOL® condenser or heat pump.

The durable galvanized steel cabinet protects internal components from corrosion and daily wear. Inside, copper “A” coils with enhanced aluminum fins promote efficient heat transfer and improved humidity control. Full internal insulation reduces condensation and energy loss, helping maintain consistent indoor comfort while keeping operating noise low.

This model uses a PSC blower motor, offering straightforward reliability and proven performance. A built-in filter rack allows for quick filter changes, and compatibility with optional electric heat kits (5kW, 7.5kW, or 10kW) makes it easy to add auxiliary heat for colder climates.

Smart-home ready and compatible with most third-party thermostats, the MRCOOL® Signature Series 24k Multi-Position Air Handler gives homeowners flexibility without being locked into proprietary controls. Backed by a 10-year limited parts warranty, it’s a practical, efficient solution for long-term home comfort.
