My roof units are really loud outside the coach, but when my front compressor kicks in, I get a pulsing vibration inside the coach that shakes my brains. Lazy Days hasn't been able to fix it. It just makes me crazy. It's like a harmonic waveform that really messes with your hearing. I've read in a couple of places that it might be a bearing that's failing in the compressor, but it shakes the whole roof.
From an operation standpoint, if the temp will go below 45, I just switch the heat to AH.
