heat pumpMitsubishi Electric 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 Cooling & Heating systems. The Hot StartTM 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.
