Mitsubishi Mr. Slim Installation, Service & Parts

Dawson Dodd is THE ONLY certified Mitsubishi Mr. Slim Diamond Contractor and Mitsubishi City Multi Diamond Designer in the Saint Louis area. The Mitsubishi Electric Cooling and Heating systems are superior to most domestic systems and are tested before they leave Japan. In spaces where other heating and cooling systems fall short, Mitsubishi can deliver low-cost, energy efficient service that maximizes a homeowner’s control and comfort.

Mitsubishi heat pumps do not use electric heat. They use the heat that is already in the air, even when the outside temperature is near zero. Inverted Compressor Technology maximizes energy savings by making sure only the energy needed to cool or heat an area is used. They also use R-410A, an environment friendly refrigerant and a high percentage is recyclable.
