Product Description

MRCOOL® Universal® Series 2nd Gen R32 Inverter Packaged Heat Pump

The MRCOOL® 2nd Generation Universal® Series Inverter Packaged Heat Pump delivers efficient, dependable heating and cooling in a comprehensive system designed for year-round comfort. Its DC inverter compressor operates at variable speeds, adjusting output in real time to meet your home's exact demands. This reduces wasted energy, extends system life by minimizing wear, and keeps noise levels low.

With an 18 SEER2 efficiency rating, the Universal® packaged heat pump helps lower utility bills while maintaining strong airflow and consistent performance. It is engineered for extreme climates, providing heat in outdoor temperatures as low as -22°F (-30°C) and cooling in conditions as high as 125°F (52°C).

R-32 refrigerant gives it a lower global warming potential than older refrigerants. The unit installs in vertical upflow/downflow or horizontal configurations, making it suitable for replacement projects and new installations alike.

Backed by a 10-year parts and labor warranty.

Professional installation by a licensed HVAC technician is required.
