Cooling Down Your Kitchen Without AC: I Tested 3 Methods, Saved 50% on Electricity

If you’ve lived through a Chengdu summer, you know: cooking in the kitchen is pure suffering.

I used to rely on AC to cool down while cooking, but the electricity bill made me wince every month—July’s bill was over 600 yuan, with kitchen usage accounting for most of it.

So I did some research and found three alternative solutions. Rotating between them, my August bill dropped to 360 yuan.

Method one: circulation fan + ice blocks.

The principle is simple—accelerate air flow plus physical cooling. Ice blocks, in case you don’t know, are those freeze-able containers that provide sustained cooling once taken out of the freezer.

I got a USB-powered mini circulation fan for 29 yuan, positioned it by the kitchen window to blow air through. On the opposite window, I hung a wet towel to boost the evaporative cooling effect. In testing, room temp dropped 2-3 degrees—very noticeable.

Method two: heat-blocking curtains + off-peak cooking.

I later installed kitchen roller blinds. On afternoons with strong western sun exposure, closing the curtain versus leaving it open made a 4-degree difference in room temperature.

So now I avoid cooking during peak sun hours (3-5 PM) and shift to 7 AM or 8 PM instead. Morning is naturally cooler; evening lets me open windows for ventilation after cooking.

Method three: pre-cooling.

A bit more “luxurious” in approach, but the most effective. One hour before cooking, blast the AC at 16 degrees to cool the kitchen down, then turn it off and start cooking.

实测 this keeps things comfortable for 1.5-2 hours—way more efficient than running AC continuously.

Rotating through all three methods, my entire summer kitchen electricity costs dropped by nearly half.

Of course, if your kitchen setup allows installing a dedicated range hood AC unit, that’s the most hassle-free option. But for renters like me? Renovation costs make that impractical.

These solutions work for anyone in a similar boat—not looking to renovate, but wanting meaningful improvement.
