Ductless Split Air Conditioning Systems:

To duct, or not to duct - that is the question.

Modular systems available. Add up to four indoor units to heat and/or cool multiple rooms.

For small offices, historic buildings, or other applications where ductwork is too costly, impractical or even impossible, there is a quality alternative. Ductless systems provide multi-room air conditioning that's quiet, attractive and effective.

The traditional alternatives to central air conditioning - window or through-the-wall units - will get the job done, but they can be loud, unattractive and inefficient.

Through-the-wall units, or PTAC (Portable Terminal Air Conditioning) Units, are installed by cutting into an exterior wall and placing the unit inside a special sleeve to hold it in place.

Window units, as the name implies, are placed into a partially-opened window.

Window and through-the-wall units have potential security issues - a unit could be removed for access into a building through the unit opening.

Both are also noisier because they have the condenser motor and fan inside your room. In ductless split units, the noisy condenser is outside.

Can you find the Ductless Split unit in this room? Low profile wall-mount ductless blends into any room.

Recessed ceiling-mount models are also available. When installed, it looks similar to a central AC duct register.

Unit Style Comparisons:		Through-the-Wall Unit (PTAC)	Window Unit	Ductless Split Unit	Central AC
Noise Level		Moderate Inside condenser/fan	Noisy Inside condenser/fan	Quiet Outside condenser/fan	Quiet Outside condenser/fan
Installation		Medium Requires cutting into exterior wall of building	Easy Mounts in open window	Medium Mounts on interior wall or ceiling - needs piping to exterior condenser	Difficult Requires ductwork and piping to interior and exterior units
Cost		Medium	Low	Medium	High
Appearance		Varies Doesn't block window. Attractive models available	Unattractive Blocks view from window. Visible from inside and outside	Attractive Low profile wall-mount or recessed ceiling-mount options available	Nearly Invisible Only registers are visible from inside. Best option for visual appeal
Expandability		None One unit per area	None One unit per area	Good Can add-on up to three units	Best Anywhere ductwork can go
Efficiency		Good	Good	Best*	Better
Ease of Care		Easy Washable filters and no belts	Difficult Must be removed and stored seasonally	Easy Washable filters and no belts	Medium Regular filter and belt changes

*Ductless splits have some of the highest rated efficiencies available. And because the air doesn't have to travel through ducts - usually located in 100 degree attic spaces - there are none of the usual energy losses associated with ductwork (a typical system loses 30-50% efficiency in the duct system). All of the cooling/heating goes right where you want it.
