What to Look For

Ductless split air conditioners offer a wide range of flexibility, as there are many choices for placement. Ductless split systems have both an indoor air-handling unit, as well as an outdoor compressor. The two components are linked through tubing. When looking for a ductless split air conditioner, you should look over the efficiency, BTU (British Thermal Units) and quality of the brand. The higher the efficiency, the less money you will pay for energy bills. The BTU measures the amount of square footage the unit can cool and it's essential that you get the right size for your home.

Common Pitfalls

Split air conditioner units can be difficult to install, and it's harder to find qualified professionals willing to do the work, as most are used to putting in duct systems. Ductless split air conditioning units also have issues with leaks. There are different types of leaks that can occur, which can become difficult to fix. Lastly, it's essential to purchase the right sized unit, as a unit that is too small will not effectively cool the home and one that is too large will not remove enough moisture.

Where to Buy

Sears offers great deals on various top-of-the line air conditioner units, including ductless split systems. As of 2010, the Sears store offers $325 dollars off your purchase, as well as a free heating and cooling estimate.


The price of ductless split air conditioner units range from around $1,500 to $5,000, depending on the BTU and overall efficiency. These units typically cost $1,500 to $2,000 per ton (12,000 BTU per hour). The overall cost of your unit will depend on the square footage you need to cool and the type of efficiency you want. If you choose to get a high-efficient air conditioner, such as a SEER (Seasonal Energy Efficiency Ratio) brand, you will pay more money for the actual system, but will save money on energy bills.
