The MRCOOL® Monoblock MTHP 10,000 BTU 115V Heating & Cooling System is a compact, all-in-one wall mounted comfort solution designed for spaces where a traditional outdoor condenser is not practical. Available from MRCOOL DIY Direct, this system delivers efficient year-round heating and cooling without requiring a separate outdoor unit.

Unlike a conventional mini split system, the MRCOOL Monoblock keeps the major system components housed inside one sleek indoor wall mounted unit. That means no outdoor condenser, no traditional refrigerant line set connection, and a much simpler installation path for apartments, garages, workshops, offices, sunrooms, cabins, tiny homes, additions, studios, and other small spaces.

All-In-One Heating & Cooling With No Outdoor Condenser

The MRCOOL Monoblock MTHP is built for homeowners who need reliable climate control without the space, appearance, or installation challenges of an outdoor HVAC unit. Its true monoblock design makes it an excellent option for rooms where exterior equipment is difficult, restricted, or simply unwanted.

Efficient DC Inverter Comfort

Built with DC inverter technology, this system adjusts compressor output based on room demand instead of constantly cycling on and off. The result is smoother temperature control, quieter performance, improved efficiency, and dependable comfort throughout the year.

Smart Control With WiFi Compatibility

Integrated WiFi compatibility allows you to control the system from your smartphone using the MRCOOL Connect App. Adjust temperature settings, change modes, and manage comfort from virtually anywhere using a compatible iOS or Android device.
