Ductless Air Conditioning Costs Ductless air conditioning is also known as split-system with its condenser unit mounted outside the building, and the evaporating unit mounted inside its climate zone with no ductwork. Refrigeration pipes pass into the building between condenser and evaporator.You will find that the cost of ductless air-conditioning installation varies by type of unit, its cooling-capacity and efficiency rating, and the local labor rate.In the following table the Labor Cost figure is what the able DIY person should expect to save by performing the corresponding tasks.Ductless A/C installation: 600 sq.ft. zone for cooling and heating, with remote control.ItemUnit CostDuctless A/C: mini-split system, 12,000 BTU/h cooling and heating, 115 VAC; with all trim, weather stripping, hardware, and miscellaneous material.$1,206each1$1,206Upgrade: new electrical circuit, 30 feet, 115 VAC, 30 amps breaker; existing load center space; 1/2" EMT tube exterior surface mount.$3.13per foot30$94Material Cost$1,300each1$1,300+ Labor Cost (A/C)$42per hour5$210+ Labor Cost (electrical)$42per hour3$126Total Cost$1,636$1,636Other considerations and costsTaxes and permit fees are not included.

I'm on Long Island, so I imagine you wouldn't know the going installation rates for my area. However, would you have a ballpark figure of what it might have cost you if your unit was strictly A/C, and without the added insulation? This site has prices for units only: How Much Does a Mitsubishi Ductless Air Conditioner Cost? They list the unit we have (18,000 btu, 26SEER) as $3k, pretty sure we paid a bit less than that, given all our costs. The installation will be the same, I think, on an A/C only unit as an A/C/heat unit.

The installation required a 20amp 240 volt service and an exterior electrical outlet within 25 feet (don't ask me, the county said on the permit that it is current county code to have an outlet for servicing exterior heat/cool units). The heat pump box was mounted on the side of the house above the snow line, insulated fluid (refrigerant) cables run up two and a half stories to the attic, across the attic and into the back of the head unit on the wall. So they were up in the attic anyway. My impression, looking at the bill, is that the install portion was just under a grand. That included two "service visits" as well, at 6 months and a year, to check on the system, clean the 4 filters, etc. The electrician was from the same company that put in our 4.8kW solar panels, so I think we got a deal from them. The Fed and state rebates came to about $400, based on the size we were heating vs the size of the house, with the state chunk being the larger. 33,571 posts, read 32,296,961 times

Let us compare the major differences between the two options.

A ductless mini-split system has two main components—an outdoor compressor and an indoor air-handling unit. A conduit links the outdoor unit with the indoor unit. As implied by their name, the ductless mini-split system does not require ductwork, making it the more convenient cooling option for older buildings with thick walls. It basically keeps your room temperature at a constant temperature, unlike an air conditioning unit that goes on and off throughout the day. In the winter, the system works in reverse by absorbing heat from the outside air and moving it indoors to heat your home, too. Their compact size allows for greater flexibility in temperature zoning—air conditioning is limited to the rooms in which the air handlers are located. These systems tend to run quieter than central air conditioning systems, and are easier to install. Some ductless mini-split models have the highest efficiency rating of any type of air conditioning system. Although a ductless mini-split can save you money in the long run, the initial installation cost can run high.

It may be difficult to find qualified, professional installers. Improper sizing or placement can mean that your unit runs less efficiently. There are also some home owners who have aesthetic issues with a wall mounted unit. A central air conditioning system treats air at a central location and distributes it to and from rooms by one or more fans and a series of ducts. Supply ducts and registers carry this cool air from the air conditioner to the home. The air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers. If your goal is to keep your whole house cool, central air conditioning is most likely your best option. With newer models, you can count on efficient, cool and comfortable temperatures and lower humidity. The system is also virtually invisible, and it adds value to your home. As with the mini-split system, you can run into cost problems if the unit has not been properly sized. (However, the upfront cost is considerably less to just replace an existing system with a new central air system rather than with a ductless mini-split system.)
