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 can be installed in upflow, downflow, or horizontal configurations, making it ideal for tight spaces like closets, attics, or crawl spaces. Its slim, compact design allows for seamless integration 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. Inside, copper “A” coils with enhanced aluminum fins offer excellent heat transfer and humidity control, while thermal insulation minimizes energy loss and reduces condensation. This translates to lower utility bills and more effective indoor comfort. Installation is quick and straightforward, helping reduce labor time and costs. An air filter rack makes change-outs a breeze, and an optional electric heat kit extends heating performance in colder climates. The system is smart home compatible, working with most third-party thermostats to give homeowners flexible control without locking them into a proprietary platform.
Backed by a 10-year limited parts warranty, the MRCOOL® Signature Series 24k Multi-Position Air Handler offers peace of mind along with powerful performance. With its durable build, energy-saving features, and flexible installation options, this air handler is the ideal solution for dependable, efficient home comfort.
