In the past, in extremely cold climates, zoned systems sometimes failed to deliver home heating with ultra efficiency. But today, thanks to Mitsubishi Electric's patented Hyper-Heating INVERTER™ technology, a zoned system can deliver efficiency and comfort benefits all year round, even at temperatures as low as -13 degrees Fahrenheit. Switching between cooling and heating modes? It's as simple as pressing a button on the handheld remote controller. Whether your region faces extreme heat, extreme cold, or both, choose a zoned cooling and heating system from Mitsubishi Electric to achieve lower expenses and, most important, unparalleled comfort.
