Product overview
MRCOOL Signature Series TruInverter 4 Ton 18 SEER2 Heat Pump Condenser - MCAESHV8T4821BA
The MRCOOL Signature Series TruInverter 48K heat pump condenser provides efficient, variable-speed heating and cooling for whole-home comfort. TruInverter technology continuously adjusts compressor output to reduce temperature swings, improve humidity control, lower sound levels, and avoid the energy waste of frequent on-off cycling.
The outdoor unit is factory-charged with lower-GWP R-454B refrigerant and supports MRCOOL No-Vac Quick Connect line sets for a cleaner, faster installation. A durable gunmetal cabinet and protected outdoor coil help it stand up to demanding year-round operation.
This listing includes the outdoor condenser only. Pair it with the compatible TruInverter multi-position air handler MCAEAMPVT48F21BA. A thermostat, line set, heat kit, and other installation materials are sold separately. Licensed professional installation is required.
