1.5-ton Air conditioners (ACs) are popular in India, particularly for residential use. They are well-suited for mid-sized rooms, which are common in homes, providing efficient cooling for spaces ranging from 150 to 200 square feet. The 1.5-ton units are cost-effective, typically being more affordable than larger alternatives, and they also boast lower operating costs due to their energy efficiency. We suggest choosing air conditioners with an inverter compressor. Unlike fixed-speed compressors that just switch on and off suddenly, inverter ACs can adjust the cooling capacity of the compressor based on ambient conditions. Certain modern ACs also have AI that can help them factor in user behaviour and temperature preference before adjusting cooling to deliver the most comfortable experience. Furthermore, the popularity of this size means there's a wide variety of models and features available, catering to diverse preferences and budgets. Here are a few good 1.5-ton split inverter ACs that you can find on Amazon.
