Power savings of 5 star ACs over 3 star ACs can be between 13-15 percent. So, there is more importance given to the star rating as it directly influences your monthly electricity bill. The Air conditioner's power consumption is dependent on its star rating. The higher the star rating, the higher is its cooling efficiency with less power than other ACs that have lower rating. A 5 star Ac is costlier than a 3 star or a 2 star AC but the energy efficiency is far more better than 2 star and 3 star ACs. But a 5 star air conditioner will provide the same amount of cooling using lesser power than a 1 star , 2 star or a 3 star air conditioner of same tonnage.

Benefits of using 5 star AC over 3 star AC

  • Low power consumption and great efficiency
  • Reduces montly electricity bills
  • 5-star AC is cheaper in the long run.

    Below is the comparison of ACs of some trusted brands....

    You can see list of our Why buy 5 star ac over a 3 star ac? below, perform Side-by-Side comparison. If you need further help, do have a look at Conzumr Guides and Tips. Alternatively you can view all Air Conditioner to choose your own favourites.


  • An air conditioner is basically a fridge without the insulated box. A fridge only cools the space inside it, but an air conditioner cools the room outside.

    There are many features to look for while buying an ac like type of ac inverter or non-inverter, hot cold feature, tonnage, energy efficient class, various functions, air swing direction etc

    Inverter AC:

    An inverter air conditioner consumes much less electricity as compared to non-inverter. An inverter AC means that the compressor is powered by a variable speed drive, which enables the compressor to run at a range of speeds from slow to fast, to match the output required. Inverter air conditioners are able to vary their operating capacity. You would be really surprised to find the amount of money you can easily save by making use of this latest technology. When purchasing an inverter air conditioner.

    There are different types on Inverter ACs like:

    • DC Inverter AC - Converts AC to DC current and then back into AC current. Due to variable frequency, the compressor motor is able to work at variable speed and hence is more efficient that conventional non-inverter or fixed speed ACS.
    • Inverter Heat Pump - It is an inverter AC which pumps out over 3 times more energy than the traditional heat pumps. It is mainly used in Acs which come with both hot and cold feature
    • 3D Inverter AC - It is an inverter AC which has vents on the side that helps in removing hot air and calling the room faster
    • Multi Inverter (Multi Split) - It is an inverter AC which is used in ACs which support different capacity and style indoor units for one single outdoor unit
    Non-Inverter AC: Non inverter or Fixed speed air conditioning deliver a fixed amount of power via a fixed speed. This means the compressor has to stop and start to maintain the desired room temperature. This means that it operates either at full or minimum speed. Switching on this type of unit will start to run on full load thus consuming more power.

    It is a fluid that is used in refrigerators and air-conditioners to remove heat from the inside and throw it out in the atmosphere.

  • R290 - R-290 is a Greenest new hydrocarbon Propane refrigerant which is completely halogen free and hence seems to cause no harm to ozone layer. We have few manufacturers who are using this refrigerant and marketing their models as 7 star. The drawback of this refrigerant is that it is highly flammable and hence need extra security measures which adds to the cost of the air conditioner.
  • R-32 - R-32 efficiently conveys heat, it can reduce electricity consumption up to approximately 10 percent compared to that of air conditioners using refrigerant R-22. R32 is proposed to be used in some ACs which currently uses R410A. It is mildly flammable and has similar performance and operating conditions to R410A. It has a lower global warming potential (GWP) than the commonly used HFCs.
  • R410A - R1410 is the green gas and an environmentally friendly refrigerant which is Non-CFC. That meant in case your system ever leaks, it won't cause any harm to ozone layer. R-410 A refrigerant is better in terms of ‘global warming’, safe and more energy efficient.
  • R22 - R22 is a single hydro-chlorofluorocarbon (HCFC) compound. It has low chlorine content but causes ozone depletion. R22 wont be manufactured from year 2010. Only recycled or remaining stock of R22 can be used.

    This is a superior type of a compressor and it compresses air in a confined space. These are more compact, operate quietly, built for continuous operation and typically see less maintenance. The down side is the initial costs are higher. For less than 3 ton these are good options as they don't need high duty cycle and have better energy ratings.
