The MRCOOL® Universal® Series 36K DC Inverter Heat Pump System is built to deliver dependable, high-efficiency heating and cooling—even in extreme outdoor conditions. Whether you're facing frigid winters or sweltering summer heat, this powerful unit ensures consistent indoor comfort without compromise. With an impressive 18 SEER2 rating, it offers energy-saving performance that helps reduce utility costs while keeping your home comfortable year-round.

The MRCOOL® Universal® Series 36K Heat Pump System was designed with flexibility in mind, the 36K Air Handler supports upflow, downflow, and horizontal installations. Its slim profile makes it easy to install in a variety of spaces, including attics, closets, and crawlspaces. For added convenience, it’s compatible with the MRCOOL® NO-VAC® Quick Connect® line set, which eliminates the need for vacuuming or flaring—streamlining installation and saving time.

These kits provide additional heating capacity and emergency backup heat when needed, boosting efficiency in extreme climates. At the heart of the air handler is an M-shaped evaporator coil with a large surface area that improves airflow and maximizes heat exchange.
