Description
The MRCOOL TruInverter MCAESHV8T2421BA is a 2-ton variable-speed inverter heat pump condenser on R-454B refrigerant, AHRI rated at 18 SEER2 / 10 EER2 / 9.0 HSPF2 with the matching TruInverter air handler. Its inverter compressor modulates continuously to match the load, delivering steadier temperatures, better humidity control and lower energy use than a single-stage system, with heating down to -5°F.
The MRCOOL® Signature Series TruInverter™ 24K Heat Pump Condenser delivers reliable, energy-efficient comfort all year long, making it an excellent choice for homeowners who want strong performance without high utility bills.
With efficiency ratings of 18 SEER2 and 9 HSPF2, it provides consistent heating and cooling while keeping energy use in check—whether you’re upgrading an old system or installing new.This unit comes factory-charged with R-454B refrigerant, a next-generation, environmentally responsible option that offers excellent heat-transfer performance while significantly reducing global warming potential.
Factory charging also speeds up installation and minimizes labor and handling errors.Further simplifying the setup, this system is designed to work seamlessly 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.At the core of the system is TruInverter™ variable-speed technology, which continuously adjusts compressor output to match real-time demand.
This delivers more stable indoor temperatures, improved efficiency, quieter operation, and reduced wear on system components for a longer service life.Designed for quiet operation, the TruInverter™ 24K runs at just 67 decibels, comparable to a dishwasher, with a sound-dampening top that further reduces noise.
Durable construction includes a steel louver coil guard and wire fan discharge grille to protect against debris and weather, along with a service-friendly layout for easier maintenance.For added peace of mind, it’s backed by a 10-year parts warranty and a limited lifetime compressor warranty. With high efficiency, quiet performance, and rugged reliability, the MRCOOL® TruInverter™ 24K is a smart, long-term investment in home comfort.
