katanapilot Posted September 14, 2020 Share Posted September 14, 2020 Given the numerous posts and prior experience with a Dometic noisemaker air conditioner, I have contemplated replacing the A/C unit on our brand new Oliver with an Atwood Air Command heat pump. I had done this previously on our MBS based motorhome and we were extremely pleased with the results. That being said, I was aware of one Ollie owner who has an Air Command A/C factory installed in his Ollie and he indicated to me he wasn't thrilled with the noise level from it either. So we agreed to take measurements using the same iPhone app and although not scientific, I am hopeful the results are different enough to warrant the change to the Air Command. My results are listed below and I expect John will weigh in at some point when he is able to take similar measurements on his Ollie. Since I'm not sure I can attach an Excel file, the list will be in this order - Location, Baseline measurement, Low Fan, High Fan with compressor running (all measurements "A" weighted DB) Front dinette seat (phone on table) - 35, 68, 71 Rear dinette seat (phone on table) - 34, 71, 72 Left bed (phone on bed at aft end) - 31, 70, 74 Right bed (phone on bed at aft end) - 32, 70, 73 Standing under A/C (phone held at 5') - 32, 76, 78 Looking forward to the comparison with the Atwood. 4 1 Link to comment Share on other sites More sharing options...
