“Window-type air conditioners are a popular option, since they are affordable and easy to install. However, they are also the least efficient type, which makes them the most expensive to use! The main drawback of window air conditioners is having an opening on your wall: this disrupts insulation, and warm outdoor air can easily leak in.
Mini-split air conditioners offer a much higher efficiency than window air conditioners. If you compare two units of the same cooling capacity, the mini-split will normally consume 2 to 3 times less power. Mini-splits also produce less noise than conventional air conditioners, which is a comfort advantage.
In larger commercial buildings, chillers and variable refrigerant flow units (VRF) are an excellent option. In addition to being highly efficient, they concentrate the cooling capacity in one unit instead of a large number of small condensers. This isolates noisy equipment from offices and other occupied spaces, while simplifying maintenance tasks. Servicing one large air conditioner is easier than dealing with numerous small systems.”

As you might guess, window units are the least expensive in terms of upfront costs. However, what many people don’t realize is that what they save initially will be spent many times over the course of the unit’s life. Therefore, a mini-split or ductless system might be the best option to balance cost with efficiency.
