MRCOOL Universal Series 48K BTU, 4 Ton, 17.5 SEER2, DC Inverter Heat Pump Condenser (UHP18048-O)
MRCOOL Universal Series 48K BTU, 4 Ton, 17.5 SEER2, DC Inverter Heat Pump Condenser (UHP18048-O)
The MRCOOL® Universal® Series 48K DC Inverter Heat Pump Condenser is built to deliver powerful, year-round comfort, even in the most demanding climate conditions. Whether you're facing extreme summer heat or bitter winter cold, this high-capacity unit maintains reliable airflow and consistent indoor temperatures. With an impressive 17.5 SEER2 efficiency rating, it’s designed to reduce energy consumption while maximizing performance—making it a smart choice for homeowners who want to upgrade without compromise.
This condenser is an ideal solution for larger homes or spaces requiring robust heating and cooling. Its compact, space-saving design allows for greater installation flexibility, especially in properties with limited outdoor clearance. The system is also compatible with MRCOOL®’s innovative NO-VAC® Quick Connect® line set (sold separately). This pre-charged, sealed line set eliminates the need for vacuuming and flaring, simplifying installation and dramatically cutting labor time and costs.
At the core of the 48K condenser is advanced DC inverter technology. Unlike conventional systems that constantly start and stop, this unit automatically adjusts output to match real-time demand.
This not only improves energy efficiency but also ensures quieter operation, more consistent temperatures, and extended system life through reduced wear on components. Whether you’re installing new equipment or replacing an outdated system, the MRCOOL® Universal® Series 48K Condenser delivers reliable performance, intelligent efficiency, and long-term comfort. It’s backed by a 10-year parts warranty and a 2-year limited labor warranty, giving you added confidence and peace of mind.
