MRCOOL 2 Ton 18.6 SEER2 Universal Series Heat Pump System - R454B
MRCOOL 2 Ton 18.6 SEER2 Universal Series Heat Pump System - R454B
Overview
The MRCOOL 2 Ton Universal Series Heat Pump System combines advanced DC inverter technology with exceptional installation flexibility to deliver year-round comfort and significant energy savings. The system features the UHP18024-O inverter condenser, which continuously adjusts its speed to precisely match your home's heating or cooling demand, eliminating the energy waste of traditional on/off systems. Paired with the UAH18024-O multi-positional air handler—capable of upflow, downflow, or horizontal installation—this compact system is ideal for attics, closets, and crawlspaces.
This system delivers reliable performance in extreme weather conditions, providing efficient heating down to -22°F and effective cooling up to 122°F outdoor temperatures. A key advantage is its compatibility with the optional MRCOOL NO-VAC Quick Connect line set, which eliminates the need for vacuuming or flaring, drastically simplifying and speeding up installation. The air handler's M-shaped, 100% aluminum evaporator coil provides a large surface area for superior heat exchange and corrosion-resistant durability. With powerful performance in extreme climates and whisper-quiet operation (as low as 33 dBA), this system ensures comfort without disruption.
Backed by a 10-year parts warranty and a 2-year labor warranty, the MRCOOL 2 Ton Universal Series represents a smart investment in reliable, high-efficiency HVAC technology. Its sleek, compact design and flexible installation options make it a perfect choice for homeowners seeking powerful performance in space-restricted areas.
