Window AC:

🔊 Noise Comparison
Through-the-Wall AC units are typically quieter indoors because the compressor and fan are outside the wall, reducing indoor noise levels.
Window AC units have the compressor closer to your room, leading to higher decibel levels, especially on higher fan speeds.
If you’re installing in a bedroom or home office, a through-the-wall unit is often the quieter choice for restful sleep or focused work.
