T974S0012 Mitsubishi Electric Compressor

The Mitsubishi Electric T974S0012 is a genuine OEM replacement DC inverter rotary compressor designed for use in Mitsubishi Electric ductless mini split and heat pump systems. Rated at 900 watts and engineered for use with R-410A refrigerant, this compressor is built to exact factory specifications to ensure a proper fit and reliable long-term performance.

As a DC inverter-driven compressor, the T974S0012 continuously adjusts its operating speed in response to the real-time heating and cooling demands of the system. Unlike fixed-speed compressors that cycle fully on and off, the inverter design allows the compressor to run at reduced speed once the desired temperature is reached, minimizing energy consumption, reducing wear on internal components, and maintaining more consistent indoor comfort levels.

Rotary compressor technology delivers smooth, quiet operation with minimal vibration, making it well-suited for residential and light commercial HVAC applications where noise levels are a concern. The use of R-410A refrigerant ensures compatibility with modern, environmentally responsible system designs.

Using a factory-original compressor helps maintain system efficiency, ensures compatibility with existing electrical and refrigeration components, and supports the integrity of any remaining manufacturer warranty. Installation must be performed by a licensed HVAC technician.
