window vs split which air conditioner to consider

11 Mar 2020


Window Air Conditioners require a designated window / wall space equivalent to the height and width of the Window AC unit to be installed and can cool down a smaller area more efficiently when compared to a split AC. Therefore, if one needs an AC for a small room, they should go for a window AC.

They are quite pocket-friendly and easy to install since they come in a single unit. The maintenance cost of a window ac is also low.

In case window ACs without a remote-control facility is planned to be used, it may need to be installed at a reachable height to enable easy access to the manual controls of cooling temperatures, fan speed and other features of the window AC.

It must also be noted that the inner, user-facing portion of the AC and its extended cooling unit on the outside are an integrated unit in a Window AC. Therefore, its use at a low height needs to be thought through properly if the space where the cooling unit would project outside is a usable area like a balcony or porch, which may hamper free movement of people in such areas therefore. In such cases it may be advisable to install the window AC at a height and plan a window AC with remote control facility.


Split Air Conditioners are mounted on a wall and are generally used for large rooms since their cooling capacity is quite higher. They do not require a window for installation. They come with a compressor and condenser where the compressor is placed in the outdoor unit while the latter is placed in the indoor unit which cools the room,

The split AC also adds a new designer element in the room since they are available in various colors and patterns. These factors lead to a higher cost for a split AC. Most of the major technological innovations in this category are also available in the Split version of ACs which are now becoming the default models is use by and large.

Unlike Window ACs they do not need a wall or window cavity which is equal to the width and the height of the entire AC unit. The indoor unit of a split AC model only needs a small hole through the wall for the cables and coils to pass through but needs enough wall space for the entire indoor unit to be fitted on the inside wall. Typically, most split ACs do not need much height for the indoor unit in terms of wall space but need enough space in terms of width surely, in the range of 2 to 4 feet of space by width. Due to this nature of the indoor unit and that most split ACs also come with remote control facility by default allows their installation on the free wall space closer to the ceiling at a higher height, thereby freeing up the main wall space for other possible uses.

Since the outdoor unit of a split AC is a separate unit it can be installed at some distance and a different place from the main indoor unit, thereby giving that much flexibility for it space planning. However, care should be taken to install it in such a place where is regular maintenance is possible to be carried out without much effort or risk of accessing it, while attempting to service or clean the outdoor unit at periodic intervals.
