MRCOOL® Signature Series MCAESHS4T4221AA 3.5 Ton up to 14.3 SEER2 42,000 BTU Split System Heat Pump Condenser - R-454B

MRCOOL® Signature Series MCAESHS4T4221AA 3.5 Ton up to 14.3 SEER2 42,000 BTU Split System Heat Pump Condenser - R-454B

The MRCOOL® Signature Series 42k Heat Pump Condenser is a powerful, energy-efficient solution designed to keep your home comfortable all year. With performance ratings of 14.3 SEER2 and 11.7 EER2, it delivers reliable heating and cooling while helping reduce overall energy use and utility bills. Whether you’re facing summer heat or winter chill, this system is built to perform. Pre-charged with R-454B refrigerant, this model supports modern environmental standards with a lower global warming potential than older refrigerants. The pre-charged design also speeds up installation and reduces labor costs, making it a smart choice for contractors and homeowners alike. At its core, a single-speed scroll compressor ensures steady, long-lasting performance. Enhanced with inner-groove copper tubing, the system provides faster, more efficient heat transfer. Built-in temperature and pressure sensors offer real-time system monitoring and protection, while an intelligent defrost function prevents frost buildup for smooth operation in cold conditions. Operating at just 65 decibels, the unit stays quiet enough for residential use, aided by a sound-dampening top. Durability features include a steel louver coil guard, and a wire fan grille, the best for protecting internal components. The compact design allows flexible installation, and accessible service ports simplify maintenance. Backed by a 10-year limited parts warranty and a limited lifetime compressor guarantee, the MRCOOL® Signature Series 42k Heat Pump Condenser offers lasting comfort and confidence.
