Folks, I have an older Beaver Marque, mostly in pristine condition,
however this year I turned on the AC and it does work, however the air coming out is just cool, Not Cold...So when it is 100 degrees. Obviously the coach is not cooling down. Any of you helpful folks have any ideas? It appears that we in Spokane are now catching up with the rest of the country.... It is going to continue to be HOT!!! Thanks, will sure answer with the answer if I should luck out and receive it!
I'm not certain of this and perhaps others will comment, but I believe the A/C units on RVs are designed to produce a 15 degree differential between outside and inside air, (considering other factors of course). If that is correct, at 100 degrees, that would be 85 degree temp coming out of the A/C. Obviously the actual temp in the RV would be dependent on insulation and many other factors.
Today is my personal best for most consecutive days alive.
If you can, measure the temp of the air going into the AC return and then the temp of the air coming out. If there is a 20-25 degree difference, then you not going to get much better than that. So if the air at the ceiling near the return is 100 then you will get cooler air but it will be 80...
As best, a 20-25 degree differential between incoming air and outgoing air is all one can expect from these air conditioners. I use an infrared thermometer to verify temps. Check to make sure you have 100% separation intact and no mixing of the incoming and outgoing air as this can occur easier than one would think. These RV ACs really struggle to keep up during very hot weather.
Check the temp first thing in the AM and after about 20 minutes running you should have a 40 degree output from the AC vents, if it is charge right with no leaks. If you wait till late in the day then it will be harder to cool. Leave the Fans on high, not auto and that also will help. If you have a duct system, then check to see if you ducts are not leaking air into the ceiling. As others have stated , keep the vents filter clean.
Thanks folks, I will try it first thing in the AM. However in all the years I have had this rig, when I turn it on after the comp. kickes on the air is really cold, not to say it really cools down the rig that much. But now when the comp.
kicks in it is just kind of cool air. I will try it on high fan also, I have always just left it on Automatic... well will see what happens. wonder if it could be the cover shroud I had to replace it last fall when the other one broke.
I have two comments.. the first is made above.. They only drop the temp so many degrees.. It might just be too dang hot on the inlet side.
The second? When was the last time you went topside (As the song is titled: Up On The Roof), Removed the covers (both inner and outer) and gave the condenser coils a good cleaning, (Along with everything else up there that can be cleaned?) Makes a BIG!!!!!! Difference, trust me.
Nothin adds excitment like something that is none of your business

Thank you for the idea, I shall be on the roof first thing tomorrow morning, before it gets hot. and do some cleaning!! I replaced the plastic cover last
fall, but didn't know there was also a inner cover. Thanks again, hope that works.
Like wa8yxm, I clean the evaporator coil on the topside every 2 or 3 years. They do get clogged with dust and other trash. I spray them from inside the coil toward the outside. Of course I'm sure you are cleaning your inside return air filters,,,, aren't you?
thanks to all of you, Have cleaned everything I could clean. Sure was dusty and dirty. Today is going to be damn hot so will be trying it out for coldness. Tried it last evening and seemed to be colder, however the sun had gone down and it was cooler outside. so we shall see today in the heat of the day. Thanks and let's hope and pray your idea's do the trick!
