We turn on the AC when it gets above 90 and leave for Happy Hour in a nice cool bar/restaurant. A long tall cool one & dinner then about 2 hrs later we return to a cooler AS.
Welcome to global warming!

Yes, something is not right. Though I traded in my 25' FC with one A/C for the reason it would not cool the bedroom, I had Non ducted A/C. My 30 footer with 2 A/C's through ducted vents can cool the trailer quite well with only one unit running. I do this frequently when running on 2 Honda generators. If my 30' footer can get cool with one A/C, then so should a 25 footer. Have it checked under warranty. Rear and street side awnings definitely help.e

Something is not working. I have a 25 with one AC and have been camped at over 95 for a couple weeks...you should see a 10-15 degree drop in about two hours. Call the dealer or repair person.

I also have a 25-ft FC (2016) and have been traveling through southern California for the last week, soon to head into Nevada, Daytime temps reaching 108. After traveling half or all the day with the trailer closed up, the inside temperatures have been around 100 when I set up camp. I have one AC unit and while it takes 4 or 5 hours to cool the trailer, it will get down the temp down to the low 70s by bedtime. I pulled into Lone Pine today and the inside was 102, same as outside. It is now 73. And if you are staying in one location for several days, leave the AC turned on set to you preferred temp or you'll have to start all over again. I was going to boondock this week - not a chance - gotta plug in. Also, as others have said, try to set up with shade during the day if you can.
Good Luck

Frankyfrank: Pull, they are held in on the ends by metal tabs. Simply pull them straight down, I doubt you could hurt them. When out I pull ours once a week, vacuum them, then wash them and let them air dry before putting them back in. They are cheap, flimsy pieces of foam, but they stop a lot of dust from getting into the system as ours are always very dirty.

do you have 1 ac or 2? one is not enough for your size unit in my opinion

Our 27fb has one ac unit. We live in Colorado and camp there quite a bit. When we went out last time during a heat wave we had trouble keeping the AS cool. We cleaned the vent filters and noticed the aluminum lining above the vents was installed incorrectly. We fixed that problem and then removed the vent covers over the table and were amazed at the air flow. The trailer cooled down very quickly with outside temps at 98 and parked in full sun. We have talked about trying to get new vent covers. The AS ones really cut down on the airflow. Try taking yours off to see if that helps. The air coming out of the vents was very cold so there is nothing wrong with the ac unit. I think it is a problem (in our unit) with the air flow blocking vent covers. Take one off and look at how much air is blocked.

MHammy · 07-12-2017, 09:41 AM

Just FYI: While removing the intake air vent covers I flipped one out right into my husbands face. (We were facing each other looking up.) The sharp edge cut his face a bit. So be careful when removing them!

Mike S. · 07-12-2017, 10:21 AM

And for those of us with the nonducted roof air, I removed the air distribution box part of the ac inside of the Airstream. The airflow is much more noticeable. Only problem is, the airflow is straight down. Doesn't look too pretty either. Other advantage is the airflow wasn't as loud with the part installed. Might have to try build a better mousetrap that the wife will be happy with.

Hi

One really stupid solution: Plug in fans.

You react to temperature, but you also react to "wind speed". This is especially true when you come in all sweaty from outdoors. A $12 plug in fan from Walmart will do wonders for your comfort level compared to the air flow out of any of the AC units. They are energy efficient enough that they don't bother the math of a 30A hookup .... I have empirical data on all of this

With the interior cover off, check to see if there are any seams that can leak intake air into the output air or visa / versa. Seal suspect areas up with silver foil tape. That will maximize the efficiency of your unit. Also check & clean all filters.

greenflag · 07-12-2017, 11:55 AM

I had a 25' with a single air conditioner. In very hot weather it would not cool the interior sufficiently. As stated, everything inside is hot and need to be cooled. Let the air run 24/7 if you are a few days in the same place.

Hi greenflag, did you have ducted air? It makes a big difference.

bibbs · 07-12-2017, 05:33 PM

I think it's not doing the job. My old 75' ac would blow ice cubes, I wanted something quite snd more streamlined, so I installed a Dometic low profile, big mistake! Works the same as yours, I hate it! It's noisy and really doesn't work.

Tbeck11931 · 07-12-2017, 06:49 PM

Aluminum faced window covering is a great idea that I plan to start on soon. You have a problem with the AC unit if I had a guess. I suggest a nearby RV dealership or call the manufacturers 800 number.
BTW: if you're at a full hookup park why not leave the AC set at 75 so it's not heat soaked when you come back.

Totally agree. On my new 2017 the 15k Dometic AC unit stopped producing cold air after 6 days of use.

Everything seemed ok (it would start, compressor would kick on, no errors on the CCC2 control panel ) but it would simply not produce cold air. The air coming out of the vents should be COLD, mine was "room temperature".

Freon leak was the issue. Unit was replaced under warrantee.

Thank you guys,
Last night I slid a small flat piece of steel in the small slot and got it pulled down where I could grab it and get it out all the way. I bent the tabs a bit so it easier to remove next time. Yep they were dirty alright. First time in 4 months they got cleaned.

For GP: a fairly big dehumidifier for the non-desert areas. Mines floorstanding.

And fans. I have two oscillating table fans of about 8". Set so that blow air back towards AC intake.

The one in the front of my TT is just across from doorway (most of which leak, and open the door in the hottest time of year and expect AC performance to plateau. Or go backwards.). Fans really do make a difference on side-to-side and top to bottom cooling.

The dehumidifier takes a load off the AC. The fans help both to do their job more effectively.

Reflectix cut for all windows. Install so that a few windows admit light and the outside view. Covers for ceiling vents as well.

Afternoon shade is obligatory. AC can keep up till almost noon on 100F days, but best to hit early Happy Hour about 2-pm.

Two AC units is pretty well mandatory, is the thought. It's about options in their use, not just enormous BTU modification.

Hi

Maybe this is obvious, if so, I apologize:

If running a dehumidifier, turn it off at mid day. It's dumping heat into the space you are trying to cool. Flip it back on at dinner time. Unless you are dashing in and out of the door a lot, the humidity isn't going to climb massively in four to six hours.
