How to keep noise down?
5 Tips on Keeping Noise to a Minimum 1 Use an appropriately sized unit for your space: An overly powerful unit will be triggered to turn on and off a lot, which is annoying to many; a unit with insufficient cooling power will be triggered to run constantly. 2 Keep your unit clean with weekly checks, including filter cleans and dusting (if needed). Also check the back (exterior) face periodically. A unit with residue or other obstructions on its grills will have to run more to transfer heat. 3 Seek a unit that is relatively quiet. Look at the reported loudness (in dB) of a unit, if you can find it. Look at any noise-related reviews about it, too. Take into account your own preferences: some people actually like more ambient noise; others are sensitive to it. 4 Meticulous insulation between the unit and the sleeve not only makes the unit more efficient—so it runs less—but it also dampens a portion of the noise. Also, be sure the unit is correctly installed (everything is screwed in place)—if not, there may be rattling as it runs. 5 Use operation modes and convenience features strategically: sleep mode automatically reduces noise both as the exterior temperature usually drops at night and as the unit allows the interior temperature to rise a little bit; a timer or smartphone connection allows you to get the unit on ahead of time so it does not have blast to catch up later.
