This model has found its place in the list with the highest energy with ISEER of 5.33 among the best energy-efficient 1.5-ton air conditioners.

Apart from this, the model is having several modes which you can find in other brands too like sleep mode, quick cooling also called turbo mode, etc. Being one of the most efficient air conditioners, the price is on the higher side but believe me if your usage is really high then you must choose to go with it, saving on electricity will pay back the differences within few years of operation.

Which are the best AC brands in India?

Some of the best AC brands in India are:
1. Voltas AC
2. Hitachi AC
3. Daikin AC
4. Mitsubishi AC
5. O General AC
6. Blue Star AC

Which AC is best 3 star vs 5 star?

As far as efficiency is concerned, a 5-star AC is more efficient than a 3-star AC. But if you look at the pay back period for your investment then a 5-star AC is optimal selection if you use it for greater than 12 hours per day. If your usage is less than than than you can opt for 4-star or 3-star depending on the extent of usage and your budget.

Is inverter AC any good for the extra price?

Well inverter technology is one of the game changer for a heavy equipment like AC, Fridge. It is definitely better to invest extra on your equipment with inverter technology as compared to the older non inverter technology. Inverter technology helps your equipment to even run at lower load which means if your AC is equipped with inverter technology then in case of empty room or room with only 1 person, your AC can even run at 50% load hence saving lot of electricity.


So we have tried to list out the Top 5 Best ACs in India Window ACs/ Inverter ACS/Split ACs. It is quite clear that until now if you are just looking for efficiency with a nominal budget then you may select the most efficient split AC which is from Daikin. However, if you are tight on your pocket and looking for something in the balance of price and efficiency then you may select any split AC from the list keeping in mind their service centers in your locality. However, if you are confused between split AC vs. windows AC  then as said windows AC will not give you as much efficiency as compared to split. However still if you want to go then you may select windows AC with inverter technology which I already compared one from the house of LG.

    • Hi,
      Thanks for visiting us!
      Sanyo is a good budget brand. However, when compared to the leading brands like Daikin, Sanyo might not give you at par after sales service all across India. If you are thinking of going with the budget brand , you might aspect some delays in after sales service during the warranty period depending on the cities. The variation in service majorly degrades in tier 2 or 3 cities for the budget brands.
      However, Nowadays Sanyo is getting large customer acceptance due to its high quality and low maintenance air conditioners specially in metros & tier 1 cities.
      Best of Luck!
