The MRCOOL® Signature Series TruInverter™ 36K Heat Pump Condenser delivers powerful, energy-efficient comfort year-round, making it an ideal solution for homeowners seeking consistent performance, lower energy costs, and long-term reliability. With efficiency ratings of 19 SEER2 for cooling and 9 HSPF2-4 for heating, it maintains precise indoor temperatures while using less electricity than traditional fixed-speed systems.
At the core of the system is TruInverter™ variable-speed technology, which continuously adjusts output to match real-time demand. This eliminates temperature swings, improves humidity control, reduces system wear, and delivers quieter operation—enhancing comfort while extending equipment life. This unit is designed to work with MRCOOL® No-Vac® Quick Connect® line sets, which are pre-charged and eliminate the need for vacuuming or evacuation, significantly reducing installation time and labor.
The TruInverter™ 36K is factory-charged with R-454B refrigerant, a next-generation, environmentally responsible option that provides excellent heat-transfer performance with significantly lower global warming potential. Designed for quiet operation, the unit runs at just 68 decibels, with a sound-dampening top that reduces noise without restricting airflow.
Rugged construction includes a steel louver coil guard and wire fan discharge grille. Backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, the MRCOOL® TruInverter™ 36K is a smart, long-term investment in dependable home comfort.
