SAVE ON ENERGY COSTS WITH ZONED TEMERATURE CONTROL

CONTROL YOUR ZONES

Airflow through most homes is often blocked by walls, doors and irregular construction angles, frequently making it impossible to condition all the zones in your home with one thermostat.
 
Maybe you find you spend most of your time in two or three rooms and you want to limit your energy consumption to conditioning just those spaces. Or husband and wife prefer different temperatures.
 
Mitsubishi's ductless mini splits enable you to customize your home comfort to condition the air in the rooms the way you want it, when you want it, and the energy savings can be staggering.
