A/C Loud in 2014 235BHS

Was wondering if anyone has had issues with loud A/C units? I have a dometic 13,500 btu ac unit on my 2014 apex 235bhs and it seems to be excessively loud, even on low. Are coleman units quieter then the dometic units? Also my unit is not duct, just blows out at the base of the unit so im sure that contributes. Any feed back would be appreciated, thank you in advance

I have always thought the a/c units to be quite loud....I guess I just get used to it

My previous trailer, a 2010 Keystone Passport was similar to your trailer in size and also had a direct flow A/C unit. It was bloody loud too.

The ducted unit, like in our current Brookstone is quieter, but not quiet, especially at high speed. None are.

The quietest ones were the trailers with a ducted cold air return and the A/C is isolated from the interior. Those are really nice, but usually only found on high end units (though it may be filtering down a bit in recent years).

Similar in our 288BHS. Ours is ducted or dumpable like yours. It's loud with the dump closed but louder with it open! TV doesn't go loud enough to hear over it...

Mine is loud too.

I have the exact same trailer and when it is on high fan you cant hold a conversation. Other than that love it.

I agree they are loud but not that unbearable. Some folks ears are more sensitive than other. Later RJD

My living room one 15,000 Dometic and I found the plastic blower wheel was worpped and causing a lot of vibration. New blower wheel was $8.97 and shipping was $8.98 LOL now my unit is very quiet. Also you might check to see if mud dobbers made a mud ball nest on the outside blade causing you vibration.

Thank you for the feed back am appreciative of it. Was looking at the new coleman mach 8 unit but i believe that would be a waste of money. Im sure if it was duct system it would be much quieter. Its not going to keep us from enjoying, we love the camper and it works out perfect for us. Thank you again.

My previous TT had a ducted Dometic unit that only had one fan setting---high. When it was set to dump you couldn't hear yourself think when inside. Once the unit got down to a respectable temp I would close the damper and use the ducted outlets. Not as noisy then but still rather loud. My new unit has a ducted Dometic unit with a Dometic thermostat. This thermostat allows me to choose between "Lo", "Hi", and "Au" (automatic) fan settings. During the walk-through they showed me how to set the thermo to "FAN", then set the fan to either of those three settings. Once I had the fan set then set the thermo to "COOL". If I have just set the TT up I will set the fan on "Hi", then set the thermo to "COOL" and open damper at the grill at the A/C unit so the TT cools down faster. Once the TT is comfortable I go back and set the fan to "Lo" and close the damper at grill so the air comes out of the ducted vents and the noise is much better. IF you have the Dometic thermo these setting may work for you.
