MRCOOL — Signature Series Split System (Air Handler + Cooling-Only Condenser)
MRCOOL® Signature Series 30K (2.5 Ton) Split AC System — MCAEAMPEF30C21AA + MCAESAS4T3021AA
Overview
30K Class 2.5 Ton Up to 14.3 SEER2 11.7 EER2 R-454B Cooling Only Multi-Position Air Handler Upflow / Downflow / Horizontal ECM Blower AHRI Certified 10-Year Parts Warranty
The MRCOOL® Signature Series 30K split system pairs a multi-position air handler with a cooling-only condenser for reliable comfort and flexible installation. The air handler supports upflow, downflow, and horizontal configurations and uses a high-efficiency ECM blower motor to help deliver strong airflow with efficient operation. Both components use R-454B refrigerant for a modern, lower-impact refrigerant platform.
Highlights
- Multi-position install: Air handler supports upflow, downflow, and horizontal configurations for tight spaces.
- High-efficiency airflow: Air handler features an ECM blower motor (5 speeds) for strong, adaptable performance.
- Efficient cooling: Condenser rated 14.3 SEER2 and 11.7 EER2.
- Quiet operation: Outdoor unit listed at 63 dB(A) with a sound-dampening top.
- Optional heat: Air handler supports optional electric heat kits (5 kW, 7.5 kW, 10 kW) for added heating capability.
