Once you’ve made the decision to purchase an air conditioner, you’ll need to decide which one is best suited to your needs and budget. It may also depend on your climate. It doesn’t take a lot of research, since there are basically 4 different types of air conditioner. Ducted air conditioning, split systems and window systems.
Ducted air cons
Ducted air conditioning must be the king of all types, because you can have it in every room so you are totally comfortable no matter which room you have to be in. But it costs more than the other options. However, you get more for your dollar with vents in every room. It is likely to cost more to run, since you lose coolness through the ductwork because the ceiling cavity is extremely hot, unless you pay extra for insulated ducting.
Ducted models can be evaporative or refrigerated. The former works only as a cooler, while the latter can become a heater in the winter. This saves on the expense of adding another type of heating.
