What to consider when Choosing Quiet Air Conditioners?


Units that get an "excellent" or "very good" in typical noise tests are likely to give you no problems with rattling or annoying noises.

You should try going for ACs that have low decibel levels so that you can enjoy a quiet, cool day. A normal aircon is around 50 dB.


Some air conditioners tend to blow air in one direction which can be an issue if they aren't centered on the wall.

To effectively cool your room, you’ll need central cooling, so make sure you know a unit's airflow direction or choose units with swiveling fans that can uniformly cool a room as well.


Most units are built for double-hung windows, so you'll want to consider a through-the-wall AC if you have casement windows.


Your AC unit's filter should be easily accessible for cleaning since it has to be frequently maintained for proper cooling.

Intelligent Cooling

Some units use smart technology so you can easily control them from your smartphones. You may also have the option to link them to other ACs around the house.


Some units have better warranties than others.

When you’re buying a new AC, check the manufacturer’s manual for details about the warranty for the brand and model you’re getting.
