Got a Jack Stonehouse 12000 BTU unit and whilst it’s not the quietest does a good job.
However I have noticed there is a resonance/vibration coming from it, not in the room it’s in but in the room under it and I’m potentially concerned my neighbour could get annoyed at it.
What’s the best way I could potentially reduce/dampen this vibration noise, for context standard uk older house with carpet floor and wooden floor boards under it.
