Hello. I have just purchased a 2015 21BHS. I wanted to ask others for their opinion. The AC on my unit seems to work alright, but its very LOUD. Is this normal?  Do any of you have experience with other AC units, perhaps from other manufactures? It would be lovely to have a cool interior and be able to hear myself think. Thanks in advance.

PS. Was there only 1 make / model of AC used by Livin Lite in 2015?

Central non-ducted units are pretty much all this way. My old Jayco had a Coleman Mach 1. It roared like a freight train. My 2015 has a dometic.. It is quiet(er) but still very loud. I'm afraid this is just the nature of the beasts. I can put in ear plugs, but I can't do 90 degree camper.

Not what I was hoping to hear (lol). Thanks Capt!

The air conditioner (Penguin II from Dometic) failed in July 2015 when a tube split and I lost all refrigerant.  Fortunately I got it fixed under extended warranty. The old Penguin II was a good bit louder than the new system.  The old A/C had a horizontal compressor while the new one has a vertical compressor.  In addition, Dometic had a free kit available to reduce the noise.  You had to contact Dometic with the part number and serial number of your A/C.  The sent you a kit with some new bushings and isolating tape/foam.  I got it before the original A/C failed and it didn't seem to make much of a difference when I installed it. 

One other possibility that I read about from another Camplite owner.  He had a very noisy A/C and found that when it was mounted on the camper the mounting bolts were pushed hard against the mounting holes in the camper, rather than somewhat centered.  This transmitted vibration from the A/C into the camper's frame which would resonate from the vibration, making it really loud.  He loosened the mounting bolts and tried to reduce some of that pressure by shifting the A/C a bit.  It made a big difference.

The non-ducted units will always be noisy, but if your seems to be really excessive and it seems like the whole camper is vibrating from the A/C; you may want to check the mounting.

Mine is insanely loud as well. Probably the biggest disappointment of the whole thing trailer. Much louder than the one I had in my pop-up.

The old LL forum had quite a thread on A/C noise. There is an aftermarket kit that fits some of them that replaces the condenser fan blade and adds an electronic speed control. This cuts outside noise a lot and maybe inside as well. Go to to aluminumcamperforum and search the archives section.

Mine is quiet, which can be caused by a number of reasons including loose components and worn rubber gaskets that can lead to your AC being noisy. Regular AC inspection and maintenance can help you figure out why it's noisy and fix them.

It was also noisy before but I managed to fix it, very lucky to have found a fix.

Installing an AC silencer to assist decrease noise from the cooling system. However, keep in mind that the sound reduction may be minimal.

In order for your air conditioner to reduce noise you must check the AC rubber gasket and perform regular AC maintenance so that you can find out why your air conditioner is making noise and fix it.

Freon is a non-combustible refrigerant that provides chilly and comfortable air in RV air conditioners. If there isn't enough of this material, it can generate annoying air conditioner noise.

Maybe this is an indicator of an issue with the fan motor. This sound may also be caused by a broken motor in the compressor of the condenser system.

To insulate the compressor of your air conditioner, you can contact an HVAC specialist to install a noise blanket. This will help to reduce noise without affecting the function of your air conditioner. Alternatively, you can reduce the noise level by wrapping a noise-dampening casing around the air conditioner.
