American Standard/Mitsubsihi Ductless Split Systems

No ductwork? No problem. Even homes without ductwork can be filled with comfort and peace of mind thanks to American Standard Heating & Air Conditioning ductless systems. That’s because these energy-efficient systems forgo the ducts in favor of a pair of indoor and outdoor units to heat and cool your home.

Have a look at the ductless air conditioner and heat pump units that are available. And remember that your comfort level as well as the energy-efficiency and price levels will vary based on your individual needs.
