FYI/Airconditioning

We did not feel we were getting good air delivery on our 38ft 2004. Took off the vent and removed the damper. It was not sealed right. Put foil tape to keep the cool air returning to the return air chamber before it got into the coach. Made a huge improvement.
If you are having the same problem, it is easy to address.

Thanks Cedar41 (John)

Pulled off my vent covers....front had 1/8 to 1/4 inch gap. sealed with foil tape. Rear was total different story......Discharge air duct to blower had a 3 inch gap (missing part) and ducting going to coach had 1 to 2 inch gap. Additionally, clear drain tube was disconnected. It sad to see such poor workmanship coming from WRV.....They have one of the best handling coaches around....they need to pay more attention to Quality Control.
Thanks again Cedar for the post.

Thanks, I gained considerable airflow in my coach.

We used ten yards of aluminum tape in both ceiling vents and the result was wonderful. We're in Phoenix, Az. right now and it's 102 outside and 82 inside. Thanks for the tip.

Are you referring to removing the cover from the air conditioner unit itself and taping where the air conditioner is attached to the ducts in the motorhome? I guess there is no way to check/tape the individual ducts coming back in? Since I have a 2004 Alpine Coach, same year as yours, I guess I better check mine.

Jim A.:
I removed the cover inside the coach. With the air running, if you put your hand up on either side of the aluminum plate and feel a draft of cold air then that's where you need to look. That cold air should be going to the ducts. I did not take the aluminum plate off.

[Jim A]

Thanks. I will check it out this weekend and see if I need to fix anything. More AC is always nice!

Enjoy Phoenix!

Take the plate off too. The baffle is behind the plate and that is where lots of the problem was with ours. If you want more information email us and we will reply with a phone number to call. Texas608@aol.com

..leaky duct work is a problem everwhere-Rv's /home's/commercial....nowhere are you immune to sloppy work except with proper oversite management....aluminum tape and clear caulk and thin sheets of aluminum that you can cut with sissors are the answer on the road.....remember to do both the make up air and the supply side checking for leaks very carefully....remove any black plastic vinal tape and use aluminum tape....vinal tape is crap and degrades very soon.....seal with the caulk from the inside using your finger....and add an electric box fan as an extra pusher when it gets really hot to move the cold air cuz it weighs more and spills out on the floor just out of the register-move the air as fast as you can stand-because it feels like 6 degrees cooler with moving air against your skin-helps evaporate faster therefore you feel cooler......lay of the alcohol because it brings the blood to the surface and makes you feel hotter-remember the cold showers from time to time to cool your whole body and go nekked as much as you or your neighbors can stand.......sweating is good but dry and hot isn't.....geofkaye

Cedar41,

Thanks for the tip. It has made a big difference in our airflow. I must say we have been surprised how well our air conditioners have done this summer. We are in Indio, CA and most days have been 107 to 115, even one day at 120 and our coach has never been warmer then 81 inside.

[Jim A]

Cedar41 was right, you need to remove the aluminum plate. I didn't find any missing parts, but lots of gaps for air to escape. My baffle chamber was cockeyed and didn't line up well with the ducts. Now it does.

It was a mild day here in SoCal, so no test on the improvement in the cooling ability. But there is better air flow.

Thanks for all of the tips.

I have a 2005 34' Alpine. I removed the a/c cover inside the coach. All I see is what looks like about a 2-1/2" X 8" duct. If I put my hand above it I feel a lot of air blowing but have no clue where it is coming from. A little instruction would go a long way.

Thanks
Ted

That "duct" you see funnels the cold air from the air conditioner above into the ducts to the front and rear of the coach. There should be 6 hex-head sheet metal screws holding the bottom plate on. Remove the bottom plate, and you will get a good idea of what is happening. Cool air from the air conditioner comes in the top by a 4" X 4" duct. You can see the blower. In mine this was where most of the air was leaking out. In addition the ducts in mine didn't line up very well with the ducts in the coach. I taped them all up using aluminum tape in order to limit the amount of air that can escape without going through the ducts.

I would like to tell you how much it helped, but I have not been in hot weather since I did the taping. But there is definitely better air flow.

I hope this helps.
