Mitsubishi Mr. Slim

There’s a lot of smart thinking that goes into making Mr. Slim your best choice for year-round home comfort – we call this Advanced Technology.


It includes features like Variable Compressor Speed Inverter (VCSI) technology, which helps Mr. Slim use only the energy needed to keep your room temperature and humidity right where you want them.

It includes the whisper-quiet fans and compressors that work so silently you won’t even notice they’re on. It includes high-speed heating and cooling which get your rooms to the temperature you want when you’ve just come in from extreme outdoor conditions. And it includes all the advanced engineering to keep your home comfortable while saving you from rising energy costs. Now that’s smart thinking.

How Does It Work?

Variable Compressor Inverter Technology

Advanced Variable Compressor Speed Inverter (VCSI) Technology provides exceptional high-speed heating and cooling performance, energy-efficient operation, and most importantly, the experience of unmatched comfort.

Conventional compressors work on cycles where the system starts up and stays at a fixed speed until it overshoots the set temperature, and then stops until the next cycle begins. This on-off cycle causes unnecessary energy spikes and also consumes high amounts of energy, regardless of the actual requirement, as the system is always producing the maximum amount of cooling or heating even when the demand is low. This results in a tremendous amount of wasted energy and uncomfortable energy fluctuations.

i-see Sensor

A New Way of Looking at Total Comfort.

Mr. Slim FE-model is equipped with the industry first i-see Sensor which measures radiant hot and cool spots in the room and focuses airflow to those specific areas.

This intelligent system not only maintains air temperature, but also controls air movement and humidity levels to prevent excessive heating or cooling and unnecessary operation. As a result, you enjoy total comfort and less energy waste – something that conventional systems were never designed to do.

Whisper Quiet

One common complaint with air conditioning and heat pump systems is noise.

Mitsubishi’s Mr. Slim units are among the quietest in the industry. Relaxation requires more than just the right temperature, the whole environment needs consideration. Don’t compromise on anything.
