Air Cooler vs AC: Which Is Better?
A room cooler costs far less to buy and run, and works on a UPS or solar; an AC cools in any weather and in a closed room. Your city's humidity decides most of it.

Electricity consumption
Our AC room coolers are rated about 180 to 350 W (0.18 to 0.35 units per hour). Inverter and DC coolers are as low as 60–100 W. A 1 ton inverter AC typically uses several times more once running. Over 8 hours a day for a month, a 250 W cooler uses about 60 units. See the electricity guide.
Cooling power
- Dry heat (Multan, Bahawalpur, Quetta, Lahore in May): a cooler cools very well.
- Humid heat (Karachi, monsoon in Punjab): a cooler feels weak; an AC is much better.
- Closed room: an AC works; a cooler needs a window open.
Load shedding
A cooler runs on a UPS, a 12 V battery or solar with a small setup. An AC needs a big solar system or generator. See 12V DC Air Cooler Price in Pakistan.
Which should you buy?
Buy a cooler if you live in a dry area, face long load shedding or want a low bill. Buy an AC if you live in a humid city or want a sealed, quiet, cold room. See our AC price list and Air Cooler Price in Pakistan.
Leaning towards an AC?
If an AC sounds like the better fit, read AC vs air cooler. It explains the same choice from the AC side: how an inverter AC removes humidity, the ton size you need and the running cost. Live AC prices are on the AC Price in Pakistan page.
Evaporative cooler vs air conditioner: how each one cools
An evaporative cooler swaps heat for moisture: hot dry air goes in, cooler damp air comes out. That is why it shines in dry heat and struggles in humid weather. An air conditioner moves heat out of the room through its outdoor unit, so the room gets cooler and drier at the same time.
This also explains the windows: a cooler needs an open window to let damp air out, while an AC needs a closed room. Read how coolers work in our evaporative air cooler guide.
