Description
The MRCOOL Signature Series MCAEAMPSF24C21AA is a 2-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 PSC blower motor moves air quietly, and an optional MRCOOL electric heat kit adds supplemental or emergency heat.
The MRCOOL® Signature Series 24k Multi-Position Air Handler is built for reliable, year-round performance and is now enhanced with R-454B refrigerant for improved energy efficiency and reduced environmental impact.Designed for versatility, it supports upflow, downflow, and horizontal configurations, making it ideal for tight spaces like closets, attics, or crawl spaces.
Its slim, compact design allows for seamless installation in space-constrained areas, while still delivering full-capacity heating and cooling when paired with a compatible heat pump or condenser.The galvanized steel cabinet ensures durability, while copper “A” coils with enhanced aluminum fins provide excellent heat transfer and humidity control.
Thermal insulation helps reduce energy loss and condensation, improving comfort and lowering utility bills.Installation is simple thanks to its installer-friendly design, which reduces labor time and costs.
A built-in air filter rack allows for quick filter changes, and an optional electric heat kit extends heating performance in colder regions.Smart home ready, the unit works with most third-party thermostats, giving homeowners flexible control without being locked into a proprietary system.
Backed by a 10-year limited parts warranty, the MRCOOL® Signature Series 24k Multi-Position Air Handler delivers durable construction, efficient operation, and adaptable installation for lasting comfort.
