Is a 5 star AC really worth the extra money? We calculated the savings so you don't have to

Air conditioners are among the biggest contributors to household electricity bills, which is why many buyers are tempted to spend extra on a 5-star model. The promise is simple: higher efficiency today could mean lower running costs for years to come. But does the maths actually support that claim?

The real cost of AC efficiency explained

For the past seven years, I have tracked consumer tech through constant shifts in hardware, platforms, and the way people actually use devices. Covering everything from budget gear to flagship hardware, I focus on what readers need to know, not on buzzwords or launch cycle hype. My expertise spans gaming laptops and chairs, high-performance PCs, gaming monitors, printers, smartwatches, earphones, headphones, Bluetooth speakers, tablets, and more, with a particular emphasis on how these products hold up in daily use. Reviews, explainers, buying guides, and news pieces all share the same goal: giving readers enough detail to make confident decisions without wading through fluff. Away from deadlines, I spend a lot of time gaming and watching films and anime, which naturally filters back into the work. Performance, comfort, display quality, and sound are judged the way players and viewers experience them, not just by lab numbers, which keeps my coverage grounded in real scenarios rather than just benchmarks.
