The MRCOOL Monoblock MTHP Series Heating and Cooling System is a compact, all-in-one solution for residential and light commercial spaces where a traditional outdoor condenser is not practical. Its wall-mounted monoblock design houses the major components indoors, eliminating the need for an outdoor unit or conventional refrigerant line-set connections.

Simple, Efficient Comfort

DIY-friendly installation requires no refrigerant handling or certified HVAC technician. DC inverter technology adjusts compressor output based on demand, providing steadier temperatures, quieter operation, improved efficiency, and reduced component wear.

A durable full-metal cabinet supports long-term reliability, while R-32 refrigerant provides efficient performance with a lower global warming potential than many older refrigerants.

Convenient Control and Condensate Management

Cooling, heating, fan, and dry modes provide year-round versatility. Additional features include swing control, silent mode, programmable timers, an LED display, and optional WiFi control through the MRCOOL Connect App.

The built-in self-evaporative system simplifies condensate management, while a water-full alarm and automatic shutoff provide added protection.
