Portable Indoor Conditioners
Using a certain type of air depends on the average room temperature. If a certain region doesn't experience much heat and the temperature changes are quite bearable, then there is no actual need for central air conditioning systems.
Portable units can be used in such places. In the same way, portable conditioners are best suited for small rooms or places where temperature regulation isn't required often. You can get more details about Air Conditioning Bangalow by browsing the web.
Portable units have a tube connected to it. The other end of tube is placed outside (to remove heat) through an opening. These do not require installation. These come with rollers to increase their portability.
Window Mounted Conditioners
Window conditioners are capable of cooling a room at a time. The cost, effectiveness and handling are slightly on the higher side as compared to portable air. These are often called either semi-permanent or semi-temporary type air conditioners.
These are permanent installations and cannot be installed without professional help. When cooling is desired on a day to day basis, this type of air conditioning is done. Walls are used to mount this system, so floor space is spared. It is expensive but has the best capacity amongst all conditioners that are used on a daily basis.
