1-Ton Window AC FAQs

Buying a 5-star 1-ton window AC is the right choice when it comes to saving electricity. Energy Efficiency Ratio of a 3-star AC is 2.9 to 3.09 while the EER of a 5-star 1-ton AC is 3.3 or more which is better than a 3-star AC because it saves more energy.

A 5-star 1-ton window AC will save you money in the long run but will cost more initially. So if you don’t mind paying a little more initially then we would suggest going for a 5-Star 1-ton window AC.

The efficiency of the split AC is more than that of window AC but the cost of maintenance of the split AC is more. The window ACs are quite noisier than the split ACs. The prices of the window ACs are lower than that of the split ACs which makes them more affordable than the split ACs. Overall, a window AC is easily affordable for middle-class family keeping the budget in mind.

The other factor that you should keep in mind while deciding whether you should buy a 1-Ton window AC or 1-Ton split AC, is the installation. Unlike a window AC which has a single unit, Split ACs consist of 2 units, an indoor unit, and an outdoor unit. Window ACs require a window for installation but Split ACs only need flat wall surface and a provision for installing the external unit on the outdoor wall. The installation of Split AC is a little complex as compared with a Window AC.
