How benchmarksutra rates window acs: maker-stated specs and Indian prices only, nothing guessed.
Quick Verdict
The benchmarksutra AC Score rates 4 window acs sold in India. Every spec comes from the maker's own product page, and every price from an Indian retailer's listing. We never use test results from other sites, and we never fill a gap with a guess.
Researched, not hands-on tested. Scores use only the specifications on each maker's own product page (checked 14 November 2026) and prices at Indian retailers (checked 14 November 2026). We did not test these window acs ourselves. How the benchmarksutra AC Score works.
What we rate
Energy efficiency (ISEER / BEE stars). ISEER from the BEE label or maker page: 2.5 rates 0 and 4.0 or more rates 100. Where only the BEE star rating is stated, 5 star = 100 and each star less = 20 points less.
Rated cooling capacity. Rated cooling capacity in kW against the nominal tonnage (1 ton = 3.52 kW): 85% of nominal rates 0, 105% or more rates 100. Under-rated "1.5 ton" units lose points here.
Condenser coil. Condenser coil material the maker states: copper 100, aluminium 40.
Noise (maker-stated). Noise in dB(A) the maker states (indoor where given; window ACs often list only the outdoor side, which we then use): 60 dB rates 0, 45 dB or quieter rates 100. Not stated means the row is left out.
Compressor (inverter + warranty). Inverter compressor named by the maker (60 points) plus compressor warranty years (4 points a year, up to 40).
Price. Lowest price we found, against the cheapest window AC of the same tonnage.
Buyer profiles
What we checked
We use only official data: the BEE star label and ISEER (from the label or the maker's page), and the maker's own product page for rated cooling capacity, condenser coil, indoor noise, compressor type and compressor warranty. Retail listings are used only for the price. Where a figure is not stated, that row is left out and the weights re-spread; we never guess. An AC is ranked only if at least 4 of the 6 rated rows are stated.
BEE star bands are set by the Bureau of Energy Efficiency and differ between window and split ACs, so compare stars within one type. Window AC labels issued under the current table are the ones we use.
What we do not rate
Real cooling speed at 45 °C, humidity removal, noise in your room and after-sales service need tests or surveys. We do not run them and we do not use other sites' results.
This method applies to window ACs first; our split AC buying guides will move to it at their next monthly update.
