Choosing the right air conditioner for your home ensures a comfortable summer season for you and your loved ones. When looking for a new AC in India, you are bound to come across various terminologies like inverter AC, 5 star AC, smart AC, and AC with air filters, but what do these terms mean and how to select AC for home to get optimal value for money?

To keep your electricity bills in check, opt for a high BEE star rating AC model with 3 star ACs offering a budget-friendly price and 5-star ACs offering the highest energy efficiency.
