Sound of water drip in ceiling

First time owner of 2012 Mountain Aire. We hear what sounds like a water drip during and after when A/C has run. We hear it in our bedroom ceiling close to the bedroom sliding doors. If we very gently press upward on the ceiling at the sound of the drip the drip seems to not to occur. Couldn't hear the drip sound during the daytime when A/C runnng only at night. After A/C has run it's cycle and turned off the sound slows down and will eventually stop. Don't know if it is water I hear or ceiling/insulation flexing due to change n temperature from A/C running. Don't see any water stains on the ceiling at all.


1. Are there bolts that may need to be snugged up on the A/C unit on the roof to help tightened a seal?

2. Since only seem to hear it at night is it ceiling/roof insulation flexing/creaking due to change in temperature since the A/C is running.

I think you need to get up on the roof and try and figure out where the AC condensation is dripping. I'm not sure but maybe a tube just needs reconnected or rerouted.


Also; While you're up there get the model number if you don't have it and then you can look at an installation manual to answer you questions about tightening the bolts, etc.

I think what you're hearing is similar to our experience in the DS. the evaporator drain on my A/C's drips down onto the roof, then runs to the corner drains. I think this is what you are hearing, and if so is perfectly normal.
we only hear it as night, as there are no other louder noises......

do you see condensate dripping from the roof rails to the ground? If so, then all is likely normal. If no, then the drip is going inside and something that needs ASAP attention so it doesn't rot out your RV.

Beachnsand ... we were in Nappanee a while back and asked about this same exact noise and was told it is normal. Something to do with the type of AC units. As mentioned in this thread, we do have condensation water coming off the roof through the corner drains ... so all appears to be fine.

X2 on the rear a/c making the drip noise. When I first noticed ours doing it I thought we had a leak in the shower or sink! Finally figured it out.
