The Average Cost of Multi-Split Ductless Air Conditioners

A multi-split ductless air conditioner is one that does not use ductwork to reach different rooms in the house. Instead it connects directly to the outdoors through the wall. A multi-room or split-level version is one that has a central condenser but several different evaporator units so it can cool down multiple rooms in more than one story. These air conditioners tend to be more expensive than the traditional versions.

Average Prices

The average price for a multi-level ductless air conditioner varies between $2,000 and $5,000 for one system in a smaller house and between $5,000 and $7,000 for a system in a house that's about 2,000 square feet in size.  Larger systems can cost up to $10,000 and more for all necessary units. The only ductwork these units require is a small hole through the wall where the evaporators are positioned. 

Sizing

The reason prices can vary so widely between units is that air conditioner sizes also vary.  Air conditioners are made at a variety of different power levels to cool down different spaces. An air conditioner that's the right size can cool a space effectively and with minimal energy use.  With multi-split AC units, size is also based on the number of evaporators or the number of rooms you want to install the air conditioner in. The more rooms, the greater the cost. 

Installation

Ductless air conditioners can be difficult to install.  The prices for most ductless units include professional installation, since this is the only viable option, especially for a multilevel version. If you are buying a unit from an online store instead of through a contractor, keep in mind the installation costs you will need to pay.  These can vary based on the unit and location of the project, but you should be able to get several different estimates.

Savings Comparison

Multi-split level units cost more than other air conditioner systems because of the number of units required.  However, one reason people choose these units is the savings they can earn by not installing ductwork throughout a house. When units are used across several different rooms, these savings can start to dwindle.  If you have several rooms you want to cool down, get estimates on both installed ductwork and buying a ductless AC system to see which is more cost effective.
