MRCOOL Universal 48K BTU R-454B Heat Pump System (4 Ton)

MRCOOL Universal 48K BTU R-454B Heat Pump System

The MRCOOL Universal 48K BTU R-454B Heat Pump System is a complete 4-ton central HVAC solution designed to deliver reliable whole-home heating and cooling with outstanding energy efficiency. This matched system includes the Universal Series Multi-Position Air Handler and Universal Series DC Inverter Heat Pump Condenser, providing consistent comfort throughout every season while helping reduce energy costs.

Powered by advanced DC inverter technology, the outdoor condenser continuously adjusts compressor speed to match your home's heating and cooling needs. Unlike traditional HVAC systems that constantly cycle on and off, inverter technology delivers quieter operation, improved efficiency, more stable indoor temperatures, and extended equipment life.

The included multi-position air handler supports upflow, downflow, and horizontal installation, making it ideal for new construction or replacement ducted HVAC systems. Compatible with the MRCOOL NO-VAC® Quick Connect® Line Set (sold separately), installation is simplified by eliminating vacuuming and flaring. Optional Universal Series Heat Kits are also available to provide supplemental or emergency heat in colder climates.
