Living in a hoa that is loaded with some weird rules... I'm stuck with a portable as traditionals are not allowed. As per noise this was a happy find overtime. A dog of mine developed thunder and fireworks issues. The noise of the ac running helped filter out the thunder/fireworks. Eventually I gravitated towards something more powerful and a bit more expensive and did some self adjusting to the machine bypassing the temperature min so to have the a/c just run continously when I needed it to. This means a room that is typically 51-52ish.
