on which factor we will select window ac unit and split unit?

Answer 1

1. First factor is your budget: window AC comes at around Rs.16000 of a good brand and a split AC costs almost 25000
2. Then the factor is noise: Split AC is to eliminate noise, are u really disturbed by noise? Most of today's window ACs also produce less noise owing to rotary compressor.
3. Do u live in a permanent home or chances of your relocation is high? Window Acs are compact and can be transported easily. Split ACs are difficult to transport and also needs slightly higher maintenance. Chances of refrigerant leakages are a little higher in case of a split AC perticularly while dismantling.
4. Looks: Certainly split AC wins in this department.
5. Convenient position : Though Split AC can be located conveniently but elaborate piping needs to be done.

Answer 2

Split AC needs only a small hole for the refrigerant pipe to enter the evaporator / cooling unit. Thus installation is easier. Window AC is cheaper to buy but needs a wooden frame and a break in the wall etc. If the wall is only 4" thick, it may not be able to support the Window model and you may need to go for split AC. The cooling capacity will remain same in both.

Answer 3

The window unit is far the cheapest option, but will need to be installed in either a window frame or a hole in the outside wall. hole size approx 600 x 400mm.
A split system (comprises of an indoor unit and an outdoor unit connected by 2 small refrigerant pipes- hence split) can be installed anywhere within the maximum pipe run as specified by the manufacturer,these systems are far more flexible in where they can be located (on the wall, on the ceiling or in ceiling) no outside is needed for the indoor unit only the outdoor unit will need to be in an area where air flow is not hindered,
the equipment is more costly and it has to be installed by a specialist a small system of around 4-5kW will cost in the region of £2-3000
