MRCOOL 3 Ton 19 SEER2 TruInverter Heat Pump Condenser

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. To further streamline the setup process, 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. This specialized compatibility significantly reduces installation time and removes the need for expensive specialized tools, making the process faster and more reliable for both professionals and DIY enthusiasts.

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. Factory charging also simplifies installation, reduces labor time, and minimizes refrigerant handling errors. Designed for quiet operation, the unit runs at just 68 decibels, comparable to a household dishwasher, with a sound-dampening top that reduces noise without restricting airflow.

Rugged construction includes a steel louver coil guard and wire fan discharge grille to protect against debris and harsh weather, while a service-friendly layout makes installation and maintenance easier. For added peace of mind, the system is backed by a 10-year limited parts warranty and a limited lifetime compressor warranty. Combining inverter efficiency, quiet performance, durable construction, and strong warranty protection, the MRCOOL® TruInverter™ 36K is a smart, long-term investment in dependable home comfort.
