Mitsubishi ElectricD uctless Heating System ST Louis offers the most technologically advanced heat pump systems in the world.
Unlike older, inefficient heat pumps, there is no cold air delivery with Mitsubishi Electric’s Cooling & Heating systems. The Hot Start TM system doesn’t activate the fan until the desired temperature is reached, so it never blows cold air. Select models use Hyper-Heating INVERTER (H2i®) technology that operates effectively down to -13º F. These models give true year-round comfort from a single system.
