Your AC is worth a fortune when it comes to tackling the scorching summer heat, but low bills are what one seeks. Discover some of the top long-lasting energy-efficient AC brands that will save a lot on power consumption.
Top Energy Efficient Split ACs

Among the finest AC brands comes the responsibility of opting for a model that does not cost you much on the electricity bills later. With technology and advancements, air conditioners no longer cost you a fortune. Having energy efficiency features adds to lower consumption, which, as a result, reduces the burdens of hefty bills as well. Among the top contenders in the market, LG, Panasonic, Haier, etc, have been ranked in offering some of the quietest and most efficient AC units. Not only that, they also provide you with a plethora of options varying from 1 to 2 ton, so that you can opt for the right capacity, as per your room size and requirements. 

Several factors and features add to reducing the power consumption as well. First and foremost is the star rating. The higher the star (max 5), the lower the energy usage. Inverter technology in an AC uses variable speed compressors that adjust cooling power based on the room's temperature and heat load outside. Another important aspect can also include the size and capacity of your AC, as an oversized unit will cool your space quickly but will also consume more energy than necessary. Check out the energy efficient AC buying guide below and opt for a model that suits your needs and requirements the most. 

Which AC Consumes Less Energy?

There are some additional smart AC features for energy saving that can help you achieve higher efficiency as well. Some split air conditioners are equipped with specialized modes like Sleep Mode and Eco Mode that adjust fan speed and temperature according to the requirements while allowing good energy efficiency. Convertible modes and AI features also optimize the surroundings, thus providing a more comfortable environment for you. Want to know more?
