Inverter compressors run continuously at variable speed instead of switching fully on/off. In a Pakistani summer that means significantly less electricity for the same cooling.
Headline numbers
Compared to a 3-star non-inverter unit of the same tonnage, an inverter typically uses 30–50% less electricity over a full season. On a 1.5 ton unit running 8 hours/day for 5 months, that can mean Rs 25,000–60,000 saved per year depending on your tariff slab.
Where inverter wins less clearly
If you only run the AC for short bursts (an hour or two at a time), the savings shrink — the compressor doesn’t get long enough to settle into low-power mode.
Our recommendation
For any room you cool 4+ hours a day in summer, an inverter AC pays for itself within 2–3 seasons.
