Window AC: Ideal for smaller rooms with an exposed window. Easier to install but can be noisier.

Split AC: Suitable for larger rooms and provides better cooling. Quieter as the compressor is outside, but installation can be more complex.

A general rule is 100 sq. ft. = 1 ton. However, factors like room size, window size, wall exposure, and number of occupants also play a role1. It's best to consult a technician for an accurate heat load calculation.

Inverter ACs have a variable-speed compressor that adjusts its speed based on the cooling needs, reducing temperature fluctuations and saving up to 30% more power compared to fixed-speed ACs.

Look for air conditioners with Energy Star certification or high ISEER (Indian Seasonal Energy Efficiency Ratio) ratings to ensure better energy efficiency and lower electricity bills.

Remote control: Convenient for easy operation.

Sleep mode: Automatically adjusts temperature for comfortable sleep.

Programmable timer: Allows you to set specific cooling times.

Choosing a reputable brand with positive customer reviews can ensure better reliability and after-sales service.

Consider whether you can install the AC yourself or if professional installation is needed. Some units may require minor renovations, especially split ACs
