Every AC says ‘whisper quiet’ on the box. Most of them lied. These are the ones I tested with a decibel meter at 2am and didn't want to throw out the window.



















Even the quietest AC vibrates against the window frame. These little additions knocked out the buzzing and rattling that drove me nuts at night.

















Learned the hard way that pointing a fan the right direction means your AC doesn't have to blast on high all night. These circulate cold air so the compressor cycles less and runs softer.


















Realized my AC was fighting the sun all afternoon. Blocking the heat before it gets in means the compressor runs less, which means less noise. Should have done this year one.



















Stopped guessing what temperature my room actually was. These let me fine-tune the AC so it's not overworking, which keeps the noise down and the electric bill reasonable.



















Even with a quiet AC, sleeping in the heat is its own battle. These are the things that let me set the AC to a moderate level instead of arctic blast, which keeps it running softer all night.
