The following are the deciding factors:
First, look at your room's location. Whether there is open space or not,
or any steel or wood window, For window AC, it requires a 27 x 18 x 29-inch ( w
x h x d) open space. If yes, then you can go with window AC. Otherwise, you have
to choose split type AC.
For split AC, you must have the layout plan for laying refrigerant copper piping to connect the indoor unit with the outdoor unit. You also think about the drain piping layout along the wall. The drain pipe's outlet should be left in the bathroom or another convenient location.
Then decide the tonnage of the AC you require for the particular room size. According to thumb rule, a 100-square-foot space requires 1.0 tonne of air conditioning. As an example, 1.5 tonne AC for 150 square feet and 2.0 tonne AC for 200 square feet. But it depends on the location of your room. Rooms on the top floor, as well as those with glass areas or sun-facing walls, always necessitate a higher tonnage than the standard tonnage. In that case, you have to choose 1.5 times more than the standard capacity.
You should consider energy-efficient AC. Choosing the highest star
rating AC, for example.AC rated at least three stars and up to five stars. The
more stars you save, the more power you save.
There are two types of AC nowadays. One is a fixed-speed AC, while the other employs inverter technology. You should use inverter technology, which is more energy efficient and produces less noise.
If you compare the price between window AC and split AC, installing
split AC will be more costly than window AC. The difference is approximately
Rs. 10,000/-.
In this way, you can choose your best ACs as per your room size and
location.
