Your air conditioning is quietly overpaying TNB. See how much comes back.
EG-COOL is a passive condenser coil by ESLIA that fits onto the split and package AC units you already own — installed in hours, no rewiring, no downtime. Enter your equipment or a recent TNB bill, and this calculator shows your saving and payback month by month.

Straight talk on fit: chillers, cold rooms and centralized/VRF systems run on different technology, and EG-COOL sits outside those. We'd rather tell you now than after a site visit.
Your Building
The longer your AC runs each day, the more EG-COOL gives back — clinics, F&B and high-runtime sites see the strongest returns.
Your Electricity Rate
Two Ways to Start
Listing your units gives the sharpest number — the one worth putting in a proposal. Starting from a bill takes two minutes and tells you whether a full walkthrough is worth booking.
Your TNB Bill History
Drop in TNB e-bills as PDF — twelve separate files or one combined file both work. The reader pulls out each billing month and its kWh automatically, and every row stays editable so you can correct anything it misses.

The 42% default reflects the air-conditioning share of a typical Malaysian commercial bill. Every building runs its own mix, so adjust it if you know yours — and your free on-site assessment replaces this estimate with a measured figure for your site.
Your Cooling Equipment
Add every split and package AC unit at your site — one tap per unit with the quick-add buttons, or build rows by hand. Every eligible unit you add is money the calculator can find.
Two ways to size a unit: enter the Watts from its nameplate sticker, or just enter its HP and the calculator works out the rest. Prices fill in automatically from the published price schedule and stay editable, so a confirmed quote can go straight into the row. Units below 2HP get their fitment and price confirmed at the free assessment.

Your Savings with EG-COOL
A number you can defend in a board meeting. Savings here are capped at 27% — the performance verified by SIRIM Berhad under ISO 14034:2016 ETV methodology (ETRC Report R374/22 / J177/22, August 2022) on an inverter split unit. The manufacturer's own published figures of 20–25% sit comfortably inside that cap. Slide it lower for a conservative case; your free on-site assessment pins down the exact figure for your building.
