I also understand that the new AC units are a little louder because of the Freon change. Don't know if it's true, just something I have heard
There is no difference in the noise level. The hardware is the same. The only difference is the refrigerant and the type of compressor oil used.
Dometic had a problem with Noise levels on the first Low Profile Penguin units(R410a) due to the type compressor they were using. After they identified the problem, they changed the design/maker of the compressor. The original compressors had a louder hum/rumble. This problem went away over 2 years ago. Doug
