MRCOOL has introduced the Monoblock MTHP Series, a 115V plug-in, wall-mounted heat pump that provides year-round heating and cooling without requiring an outdoor condenser unit, refrigerant-line connections, or the services of a certified HVAC technician for installation. The all-in-one system consolidates its primary components within a single indoor housing, requiring only two small exterior wall openings for airflow, and operates on standard household electrical outlets.
MRCOOL's wall-mounted heat pump unit delivers cooling, heating, dehumidification, and fan modes through advanced DC inverter technology that adjusts output based on room conditions. The Monoblock MTHP Series utilizes R-32 refrigerant with a lower global warming potential than older alternatives, and features smart-home compatibility with the MRCOOL Connect app, Amazon Alexa, and Google Assistant, along with an LED display, remote control, and self-evaporative condensate management.

- Condenser-free Installation
- All-in-one indoor heat pump designs reduce installation complexity, opening room for compact climate products that bypass traditional outdoor equipment constraints.
- Smart Low-gwp Comfort
- Connected controls paired with lower-impact refrigerants point to differentiated comfort systems that blend energy efficiency, automation, and sustainability.
Who This Affects Most
- Residential HVAC
- Simplified wall-mounted heat pumps expand the category beyond contractor-led installations toward faster, more accessible home comfort solutions.
- Smart Home Technology
- Voice assistant and app integration positions climate control as part of the broader connected-home ecosystem, creating value through automated energy management.
- Rental Housing
- Non-invasive plug-in systems provide landlords and tenants with flexible heating and cooling options where permanent HVAC retrofits are costly or restricted.
