MRCOOL Universal 4 to 5 Ton (48000-60000 BTU) 18 SEER Central Heat Pump Condenser

Step into the next generation of HVAC technology with the MRCOOL 4 to 5 Ton 17 SEER2 Universal Central Heat Pump Condenser. Designed for exceptional comfort and performance, this ultra-quiet unit delivers rapid heating and cooling, superior energy efficiency, and long-term savings—all while maintaining whisper-quiet operation.

Compact, Powerful, and Efficient

Perfect for homes with limited space or sound-sensitive areas, this unit provides a powerful 48,000 to 60,000 BTUs of capacity. It offers up to 80% heating output even in subzero temperatures, significantly reducing or eliminating the need for a gas furnace or auxiliary heat strip.

Advanced Inverter Technology

The advanced DC inverter system intelligently adjusts compressor speed, preventing extreme fluctuations and extending the life of the unit. This results in smoother operation, greater energy savings, and enhanced indoor comfort all year round.

All-Weather Performance

Engineered with enhanced two-stage enthalpy technology, this heat pump keeps your home warm even when outside temperatures dip as low as -22°F. The intelligent defrost system boosts heating efficiency and ensures a reliable performance in the harshest conditions.

Built for Peace of Mind

Equipped with smart protection features—such as high/low pressure protection, high-temperature discharge protection, and IPM module safeguards—this unit is built to run safely and efficiently for years to come.

Eco-Friendly Refrigerant

Using environmentally friendly, chlorine-free R-410A refrigerant, this unit helps reduce environmental impact without compromising performance. It also supports compatibility with both electronic and thermal expansion valves for versatile installation and efficient refrigerant flow control.

Flexible Installation Options

Pair with the MRCOOL Universal Central Air Handler using the No-Vac Quick Connect line for fast, easy installation, or use traditional fittings depending on your setup. No-Vac Quick Connect eliminates the need to vacuum and charge the refrigerant line, saving time and hassle.

Smart Compatibility

This unit uses 24V non-communication control technology, allowing seamless integration with third-party air handlers and smart thermostats like Nest or other WiFi-enabled options.

Certified Quality You Can Trust

Designed for use with a complete ductwork system, the MRCOOL Universal Central Heat Pump is AHRI and ETL certified—guaranteeing top-tier quality, performance, and safety.
