MRCOOL® Signature Series 60K (5 Ton) Split AC System — MCAEAMPEF60E21AA + MCAESAS4T6021AA
Overview
The MRCOOL® Signature Series 60K split system pairs a multi-position air handler with a cooling-only condenser for high-capacity residential cooling. This 5-ton class setup uses R-454B refrigerant and features larger refrigeration piping with a 7/8" suction line. The air handler supports upflow, downflow, and horizontal installs for flexible placement.
Highlights
- Multi-position install: Air handler supports upflow, downflow, and horizontal configurations for flexible layouts.
- ECM airflow performance: Air handler uses a high-efficiency ECM blower (5 speeds) for strong, steady airflow and quieter operation.
- High-capacity cooling: Condenser is rated 5 ton with 55,000 BTU listed cooling capacity.
- Modern refrigerant platform: System uses R-454B (low-GWP refrigerant).
- Long-line capable: Condenser lists up to 150 ft maximum line set length.
