With electricity tariffs where they are, some upgrades are no longer optional luxuries — they are investments with measurable payback periods.
Under Rs. 5,000: instant wins
LED bulbs throughout (payback: 2–3 months), door draft stoppers for AC rooms, and reflective window film for west-facing glass. Small costs, immediate bill impact.
Mid-range: the big lever
An inverter fan uses roughly half the power of a conventional one. If you run four fans ten hours a day, replacements pay for themselves within one summer.
The AC math
Servicing your AC before summer improves efficiency 10–15 percent. Setting it at 26°C instead of 20°C cuts consumption by roughly a third with minimal comfort loss when paired with a fan.
Track to verify
Photograph your meter weekly. Upgrades you can measure are upgrades you will maintain — and the numbers convince the rest of the household better than lectures.
