Air conditioner
Somewhere on this forum i saw some thing about ac ducting in the ceiling. I checed mine and saw it needed a good cleaning. My fifth wheel is a 2006 larado. The air ducting was never totally taped up. Over half of my cold air was circulating in the roof area instead of the coach. Everything looked original so it must've a Friday late afternoon job. Should work better now. Ronson

Well really doesn't matter what day of week or time of day, nothing in AC or heating system is tight!!
I sealed my AC and ducting for icing, as it had enough cold air leakage that the coils would ice.
Heating ducts were the same, poorly done connections at furnace and where the duct goes up into the bedroom.

Hooked up my generator and checked out ac. Big difference on end outlets. Also opened up the block on the ac in the middle. Put in a half block to help cool kitchen more. Helped in that part too.

For both A/C and heating ducts, a roll of the silvery (foil) HVAC tape is your best friend. If properly applied, it is pretty much a permanent fix. HVAC installers use it all the time in residential and commercial applications. It is your absolute best choice in most circumstances.

Yes, foil duct tape will fix both AC and heating duct leaks.
This is the foil tape not silver colored cloth tape! I used this to seal the ducts at the unit, and separate the warm side from the cold side, AC works so much better!

You also may want to check the way the ducts are terminated at each end. My bedroom duct just dumped air into the nose of the trailer.Some foam pipe insulation wedged in and taped with foil duct tape improved bedroom cooling 200%. I did the same for the kitchen vent but that did not have much effect .... must have been fairly sealed beyond where I could see. JM2¢, Hank

One thing that everyone needs to be concerned about is that once you've connected the vents to the diffuser you've now created an unconditioned air space in the atic of your rv. If the ducts are alum wire reinforced 3" or 4" round flexible ducting with no insulation and vapor barrier on the outside then you may have a sweating issue caused by cold air in the ducts surrounded by hot air in the atic. I know you might have much better air flow but the issue caused could be a lot worse. Just throwing that out there.

In most RV applications the AC ductwork is styrofoam with channels cut in it. Aluminum wire reinforced ducting is used in the furnace runs.
