What to Keep in Mind Before Buying

Before choosing a 1-ton AC, measure the room size and check insulation, sunlight exposure, and ceiling height. These factors affect cooling performance. Energy rating also matters, especially in regions where ACs run for long hours during summer. A higher star rating can help reduce electricity bills over time.

Convertible modes are useful for adjusting cooling output, while inverter compressors help maintain a steady temperature without frequent on-off cycles. Filters and cleaning functions add value for indoor air quality. Smart features such as app control and voice commands are optional but can improve ease of use.
