For anyone confused on the issue, now we are going to look at the main differences between central air conditioners and small window AC’s. First, please note that a central air conditioner is a much more complicated method requiring multiple kinds of parts. There is the condenser which sits outside the home, a duct method which carries the air through the home, a thermostat which tells the method when to run plus how to run, and multiple others. While a central air conditioner has the parts distributed in multiple areas, a window AC, on the other hand, has each of the parts housed together in the singular unit. For this reason, it is half outside, plus it is half inside. This genuinely makes the cost of a window A/C much cheaper, not only in terms of the unit itself but because of the installation as well. Now, if you’re looking only to supply air conditioned air to one room, a window A/C is much more efficient for you, however a good central air conditioner will use about 3,500 Watts of energy in order to operate and a good window unit will average about 1,000 watts. A window A/C is only designed to heat plus cool a single room. This means that heating plus cooling more rooms means more window AC’s which equals more watts. And so with all the working parts, energy usage, plus need for service, central air conditioners are not always typically the best choice for every single home. However, for larger homes, they make more sense to use. But for a smaller living space, a window A/C may make the most sense instead.
