Bridge The Gap — EG-COOL Savings Calculator

Your air conditioning is quietly overpaying TNB. See how much comes back.

EG-COOL is a passive condenser coil by ESLIA fitted to the split and package AC units you already own, a few hours per unit. 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.

Average monthly TNB bill (RM)

Air-conditioning share of that bill (%)

Your saving is worked out from what you actually pay. The 25% is a starting figure for how much of your bill goes to air-conditioning. Every building is different, so change it if you know yours. Not sure of your average bill? Upload your TNB bill PDFs below and the calculator works it out for you.

The longer your AC runs each day, the more EG-COOL gives back — clinics, F&B and high-runtime sites see the strongest returns.

Two Ways to Start

List my AC units Start from my TNB bill

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 listing your units is worth the time.

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.

Averaging basis

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 1HP sit outside the published price schedule and are not priced here.

What Cooling Costs You Today

Your Savings with EG-COOL
