Ductless systems adopt a decentralized format to cooling your home: using multiple smaller blower fan units instead of one big one the way that centralized units do. Each one is charged with heating or cooling a single section of your home, and each can be operated independently of the other.

That provides a number of advantages for the right home:


Lower Costs. By turning off the heat or air in unused portions of the house during the day, while still running it in parts of the home you are using, you can cut down on your energy usage and lower those monthly bills. Besides, ductless systems carry much higher energy efficiency ratings than window box units and portable air conditioners.
No Ducts. By getting around the need for ducts, ductless systems provide comprehensive air conditioning and heating for homes that would not be able to consider them otherwise.
Precise Control. Ductless heating and cooling systems let individual family members set different temperatures in the home to suit their tastes, eliminating squabbles over the thermostat settings.
Shades of Comfort


Mitsubishi remains the trend–setter when it comes to ductless heating and air conditioning systems. Their innovative Hyper–Heating technology is designed to provide comfortable warmth no matter how cold it is outside. Their units emphasize environmental friendliness and high levels of filtration, making them excellent for households concerned about clean air. To top it all off, they rank among the quietest units in the industry.
