MRCOOL® Signature 2.5 Ton 30K BTU Split System Multi-Position Air Handler, MCAEAMPEF30C21AA

Product Description 

MRCOOL® Signature Series 30K Multi-Position Air Handler (230V) 

The MRCOOL® Signature Series 30K Multi-Position Air Handler is designed to deliver powerful airflow, quiet operation, and installation flexibility for today’s high-performance residential HVAC systems. Engineered to pair seamlessly with MRCOOL® Signature Series top-discharge condensers and heat pumps, this 2.5-ton air handler supports upflow, downflow, and horizontal installations, making it an excellent choice for new construction, system upgrades, and space-constrained applications. 

Built around an efficient ECM blower motor, this air handler provides smoother airflow, improved humidity control, and lower electrical consumption compared to traditional PSC motors. When matched with a compatible condenser, the system delivers consistent heating and cooling performance while helping homeowners reduce long-term energy costs.

The cabinet is constructed from heavy-duty galvanized steel to resist corrosion and wear, while copper “A” coils with enhanced aluminum fins maximize heat transfer and moisture removal. Internal thermal insulation reduces condensation and sound transmission, contributing to quieter operation and improved efficiency. With an operating sound level of just 53 dBA, this unit is well-suited for residential environments where noise matters.

Installation is streamlined thanks to its installer-friendly layout, reducing labor time and simplifying service access. A built-in filter rack allows for quick maintenance, and the system supports optional electric heat kits for added comfort in colder climates. The unit is also smart-thermostat compatible, allowing homeowners to use most third-party thermostats without being locked into proprietary controls.

Backed by a 10-year limited parts warranty, the MRCOOL® Signature Series 30K multi-position air handler offers dependable performance, flexible installation, and long-term value—making it a smart indoor solution for 2.5-ton split-system applications.
