Limits to mini splits in cold conditions

[begreen]

I've got 2 Fujitsu 12k units on the same side of the house, with a patio area between. Really can't hear a thing, even on the patio

If you stand in front of a unit you can tell it's working by the air blowing

Yes, that unit is really quiet. A neighbor put one in many years ago. I stopped at their house when temps were around 20 and it was running full steam. I could hear it, but it was just a gentle hum and low fan noise.

Day mine was installed what a hot mo-fo.... I couldn't be there for the installation as other work took me away, but the good lady was. I came home, and walked up the front step, the unit would be about 10 feet away, and heard a racket. Upon hearing that I was downright disappointed. Walked in, greeted everyone, headed back out to check on the noisy install and realized that my neighbor must have put a window unit in that same day. What I heard was that window ac unit about 70 feet away,,,, the mini split was running like a beast, but whisper quiet.
