MRCOOL® Monoblock MTHP 10,000 BTU 115V Wall Mounted Heating & Cooling System – No Outdoor Unit Required – MDM10115D
The MRCOOL® Monoblock MTHP Series is a compact all-in-one heating and cooling solution designed for spaces where a traditional HVAC system or outdoor condenser is not practical. With the entire system housed inside a sleek wall-mounted indoor unit, it delivers year-round comfort without the complexity of conventional mini split installation.
Recommended Coverage Area: Up to 450 sq. ft., depending on insulation, ceiling height, sun exposure, climate, and room usage.
*Not available for sale in the state of California.*
Ideal for apartments, garages, offices, sunrooms, workshops, additions, cabins, tiny homes, studios, server rooms, and other small spaces, the MRCOOL Monoblock combines efficient inverter performance with quiet operation and DIY-friendly installation. Because there is no outdoor condenser, there is no refrigerant line set to run and no dedicated electrical line needed outside. Once installed, the unit simply plugs into a standard wall outlet.
Unlike traditional mini split systems, the Monoblock design keeps the compressor, condenser, evaporator, and controls inside one self-contained cabinet. This helps reduce installation time, space requirements, and overall project cost while still providing dependable heating and cooling performance.
Built with DC inverter technology, the system adjusts compressor speed based on room demand instead of constantly cycling on and off. This allows for smoother temperature control, improved efficiency, quieter operation, and reduced wear over time.
With cooling, heating, fan-only, and dry modes, the MRCOOL Monoblock adapts to changing comfort needs throughout the year. Integrated WiFi lets you control the system from your smartphone using the MRCOOL® Connect App, while the included remote control and LED display make everyday operation simple.
Durable metal housing, reusable filtration, self-evaporative operation, quiet mode, timer control, and swing functionality make this system a practical choice for reliable comfort in small rooms and hard-to-condition spaces.
