Air Cooler vs Air Conditioner: Which Should You Choose?

Choose an evaporative air cooler for a localised water-cooled breeze with no exhaust hose; choose an air conditioner when you need active heat removal and can vent the exhaust.

The verdict

These are different appliance types. Pick by the result you need and whether you can provide an exhaust route; do not compare airflow or tank figures as equivalent cooling-capacity measures.

Localised cooling without an exhaust hose: Pro Breeze 10L Portable Air Cooler

The Pro Breeze cooler uses a water tank and the manufacturer says its air coolers do not require external ventilation.

Actively removing heat from a room: De’Longhi Pinguino PAC EX130 Silent

A portable air conditioner uses an exhaust hose to release heat outside; the De’Longhi listing identifies it as an air conditioner.

A room where added humidity is undesirable: De’Longhi Pinguino PAC EX130 Silent

Evaporative cooling adds moisture to airflow, whereas the air-conditioning model’s stated function is cooling with heat exhausted outdoors.

Common questions

Questions before you buy

Is an air cooler the same as an air conditioner?

No. An evaporative cooler moves air over water to create a cooler-feeling breeze, while an air conditioner removes heat from the room and releases it outside.

Which is better: an air conditioner or evaporative cooler?

An air conditioner is the category to choose when you need active temperature reduction and can vent hot air. An evaporative cooler may suit local airflow where a hose is impractical and added humidity is acceptable.

Does an evaporative air cooler need a window open?

It does not need an exhaust hose, but ventilation can help avoid stagnant, humid air. Follow the specific manufacturer’s placement advice.

Can an air cooler make a room colder than an air conditioner?

An evaporative cooler does not provide the same controlled temperature reduction as an air conditioner. The products use different mechanisms, so select based on the outcome you require.
