The Research
I’ve used and tested hundreds of AC, which includes both window ACs and split ACs. I’ve also been writing about consumer electronic devices and home appliances for over a decade.
To compile this guide, I’ve used hundreds of ACs across price segments and brands in India and combed through Reddit pages that talk about their cooling technology, compressor technology, factors that impact their energy efficiency and smart features. Like all HT journalists, I review products with complete editorial independence and recommend products based on my learnings.
