We Install Mr. Slim Air Conditioners

The Mr. Slim models provided by Mitsubishi Electric come in different shapes and sizes depending on your needs. Every space is different and we are happy to accommodate those needs.

Choose from a selection of wall-mounted(most popular), floor-mounted, or ceiling-mounted air conditioners for your space.

With each Mr. Slim unit, you can expect the same level of quality that is presented in all of its features which are listed below.

Split Air Cooling & Heating

A split air conditioner means you get heating and cooling from the same unit. The outdoor unit can use air up to a certain temperature(depending on the units installed).

Most split air conditioner units can still heat the home if it’s still -25º. The mini split system is capable of switching between hot and cold air.

Hot And Cold Spot Sensors

Mitsubishi Electric’s 3D i-see Sensors see more than just room temperature. Equally important factors for feeling comfortable include radiant temperature, air movements, humidity and more.

The i-see sensors measure radiant hot and cold spots within the room and focus airflow into those spots.

This revolutionary system also controls the air movement and humidity levels, producing a much more comfortable environment then ever before.

Catechin Plus Air Filters

All Mitsubishi Electric ductless units have catechin plus air purifying and anti-allergy blue enzyme filters to eliminate bacteria, deodorize and kill viruses in the air.

The filters also trap dust, pollens, mites, and other particles which can cause allergic reactions.

Variable Speed Compressor

Most Mitsubishi Electric Heating and Cooling systems have variable compressor speed inverter (VCSi) technology which adjusts the air conditioning capacity in response to demand. This allows Mitsubishi Electric air conditioners to run more efficiently and reduce energy costs.

By controlling the compressor rotation speed more precisely, VCSi technology provides high-speed cooling and heating with extra energy savings compared to conventional models.


Installation doesn’t require any significant changes to your home. The nature of a ductless air conditioner is to be out of your way. Installation can be done in a single day for a typical project and two days for larger, more complicated projects.
