Question 2010 Dometic A/C

Several months ago, I purchased a 2010 30' ft Flying Cloud. At that time, I questioned the dealer regarding the performance of the Dometic A/C. When compared to the output of the 2005 Carrier Air V installed on my '78 Sovereign, the Dometic is substandard. So much so that, if this is what I can expect, I'll have to replace it with something else. The dealer informed me that the standard to which the Dometic is evaluated is a 20 degree spread from ambient air temp. Is that correct? If so, what are the replacement options? Apparently, Carrier left the RV market, so is there a comparable unit to the Air V? Thanks in advance.

Every roof A/C unit used in the RV industry uses the same performance standard: that being a 20*F temperature differential between the cooled air measured at the duct or outlet grill and the return air measured at the return air grill. Carrier used this same standard.

It may take more time for your Dometic to lower the inside ambient temperature in your Airstream when compared to a white box SOB, as aluminum gets quite hot in the full sun. Cover your windows on the sunny side and let the unit work.

That 20*F temperature differential is inside the trailer and has little to do with the outside ambient temperature. The FC-30 is a big trailer and might require 2 roof units if you are in a very warm location.

Question

The Carrier installed on my '78, 32 ft Airstream Sovereign is so effective it can cause condensation to form on the outside of the Airstream. The Dometic doesn't come close to the same performance (both of my Airstreams are parked side by side at my home, so it's not hard for me to compare the effectiveness of each AC unit). Is it possible that although the standards are the same between manufacturer's, the resulting performance is not? Could it be more about the volume of output air than the temperature?

What size A/C units are we talking about on each trailer. Some Units are same size but don't work as well as others. Your new trailer isn't under sized is it. I know mine is 2007 25ft. FB with 11,000btu dometic. Way to small will replace with a bigger unit when this one fails. Would like 15,000 btu unit.

My 30 foot Airstream came with two units - a 13.5 in the bedroom and a 15 in the Living area near the galley table.

With the dual zones of the new Dometic controller - expecting no problems this summer.

With my 25FB - the one 13.5 did get a workout keeping the whole unit cool - as said, these Airstreams really bake when in the sun so extend those awnings on all sides if you have them - if not you might want to purchase awnings for the street side and back windows to compliment the curb side awning.....

Perhaps it could......and that new air "distribution" box design (the one that looks like something from the set of Star Wars), does not permit sufficient air flow unless, (according to the factory), EVERY vent is open (including the one in the middle, which inefficiently directs the majority of the air straight down).....this is vastly inferior to the "old" design!

Ac

The Carrier is a 13.5 and I thought my 2010 FC was a 15, but I'm wondering if, in fact, it is. I'll have to confirm it.

The vent arrangement is strange, as the only cool spot is directly below the center vent. I've also been told by the dealer that this model of FC does not have the reinforced vent area in the aft bedroom, requiring an upgrade to the structure if I want to install another AC.

What surprises me is that my old 32 ft Sovereign with a 6 year old Carrier unit doesn't have this problem. I've never had to plan for excess sun exposure or close window shades in the daylight. I've used it in places as hot and humid as Florida and as hot and dry as the Mojave desert. No problem. So something is different and very unexpected when you consider the cost differential between my '78 and '10.

The 15 is standard in yours and mine, and not adequate for either.

What Next?

So do you have any suggestions on a solution? Are there other units that would get the results I want that are currently available? Since the Carrier is no longer made, what about Coleman? Or how about Thor coming up with a solution and advising owners how to get things right!

Airstream is captive to the Penguin. That is the only air conditioner that has a drain pan to drain the condensate through a host without dumping it over the side. There IS a "kit" of sorts to do the same thing with a Brisk Air, which still uses the old ceiling assembly the Penguin did, but it's rudimentary at best. That also assumes you want the high profile unit on top of your trailer.

Actually,

Dometic is NOT the only company that manufacturers a roof unit with a drain hose. RVP (Coleman) makes the Polar Mach low profile series that has an integrated drain pump and does not need a drain pan.

Also, Dometic has an auxiliary drain kit (#3107668.016) that can easily be used instead of the plastic drain pan. This auxiliary kit is used by every major motor home manufacturer that uses Dometics that also use an interior drain hose.

I mentioned this in another thread but didn't see a response, so I will ask it again here: do the new units have the special treatment of reflective white paint on the roof to aid in cooling?

I remember a post or posts claiming that this on its own cold reduce the heat differential by up to 10F simply because the silver of the aluminum roof actually has a very dark property to it which makes for significant heat gain inside the TT.

So, do you have the special white roofs?

Yes, I have a white top. My 2010 FC also had a white top.

Hi hansenk,
Our dealers DO have the perfect solution for our air conditioning issues: order a new one with the window awning package and a bedroom air conditioner! Problem solved!
