When choosing a new AC for home, the star rating is an important factor as it determines the amount of power the unit will use and thus directly impacts the power consumption and translates to electricity bills with high star ratings resulting in less cost of operation. Opting for an energy-efficient air conditioner for your home can ensure that you stay comfortable with powerful cooling and provides an optimised performance as well.
Consider the best 5-star ACs and 4-star AC models from top AC companies that are known for their durable designs, low cost of operation, and user-friendly features. Most of these split ACs run on inverter compressor technology for running it on versatile convertible modes as per the requirements and surroundings, and thus ensure there is no extra power usage.
Best Energy-Efficient Air Conditioners For Home
Wondering how much more efficient is a 5-star AC than a 4-star AC? When choosing an air conditioner, energy efficiency plays a crucial role in determining long-term savings and performance. The Bureau of Energy Efficiency or BEE rates ACs on a scale from 1 to 5 stars, with 5-star ACs being the most energy-efficient. While 4-star ACs are slightly less efficient, they are often more affordable upfront. Some of the leading AC brands including Daikin, LG, Lloyd, Godrej and Panasonic offer a versatile range of models in various cooling capacities from 1 ton, 1.5 ton, and 2 ton options that you can select depending on your family size and cooling requirements. Apart from energy-efficiency, you can also consider the AC power capacity, inverter or non-inveter compressor, inbuilt air filters, airthrow range and power, and configuration to make the right choice for home cooling.

Key Points To Consider When Choosing Between 4-Star And 5-Star ACs
Consider these major factors to choose the best AC in India from 5-star and 4-star options that ensures a comfortable home environment and also keeps the electricity bills in check.
- Energy Efficiency: 5-star ACs are generally more energy-efficient than 4-star models, resulting in lower electricity bills and reduced environmental impact. The star rating is determined by the Bureau of Energy Efficiency or BEE in India with higher stars indicating greater efficiency.
- Cooling Performance: While both 4-star and 5-star ACs can provide effective cooling, 5-star models may have advanced features like inverter technology which can adjust the compressor speed to maintain a consistent temperature and improve overall performance.
- Cost of use: 5-star ACs usually have a higher upfront cost than 4-star models due to their advanced technology and energy-saving features. The long-term savings on electricity bills ultimately give you a good return on the initial AC price for 5 star models.
- Environmental Impact: 5-star ACs are considered more environmentally friendly due to their lower energy consumption and reduced greenhouse gas emissions with eco-friendly refrigerants.
- Additional Features: Some 5-star ACs may offer additional features like smart connectivity, air purification, and low-noise performance which can enhance user experience and comfort with sleep modes and auto-restart functions.
