Sounds like you've found your first warranty repair issue on new Lucy. I'll bet they somehow messed up the ductwork. This may not be new tech, but it's new to the AS build teams.

New Lucy is a 25FB. She has two rectangle shaped vents in the ceiling midway in the trailer. I verified that these are the return air vents using a paper towel while the unit is running. Lucy has six additional vents on each side of her interior. Three forward of the air return vents and three aft on each side.



All of the vents seem to blowing air except the three forward vents on the street side. These do not blow any air at all.

Time to see a service tech ... all of our outlets blow cold when on AC and very warm when using heat pump. The rectangular inlets have filter material behind and respond well to light vacuuming.

Gosh, what a great suggestion about light vacuuming the return vents to clean the filters……will do this today. And, I think I will also do a formal check on the flow patterns with Zone 1, Zone 2, and both in A/C and heat pump modes.

I found that the air return vents snapped right out and I was able to get the foam filter out to clean it properly. I plan to install a better filter material than the 1/8" thick piece of foam that Airstream provided.

Here is a photo of the filter and grate removed from the ceiling.

I remember my ducted air in my SOB I previously owned prior to my Airstream. We did like it, but we did find that the discharge rate did vary per duct. Our round discharge vents had adjustable openings which allowed us to balance they system out to compensate for temperature variances.

My dealer likes the ducted vents although he commented that he felt that cool down on a hot trailer seems to take longer in his opinion. My guess is that the cool down may be more balanced and that the old open units that tend to direct a lot of air on you which makes to feel cooler more quickly.

That seems very intuitive for my brain as well

On my Serenity with two A/C units the cool down is within five to ten minutes for about ten degrees F. With my 2009 27FB, one unit, the same cool down took twenty minutes. Ambient temp about 85 degrees F.

Took delivery of my Ducted Dual Air 2015, 27fb, and noticed when the ambient air temperature in the cabin was consistent throughout zone 2 indicated that it was 10° warmer. I removed the temperature sensor cover, and discovered that the factory had crimped the sensor with the tie down. I re-adjusted it and all is good..... LOVING MY QuietStream!

Although others may minimize, disparage, and poo-poo the ducted air... *** isn't it GREAT !!! ***
... and, not just for the AC in hot areas, but also for the heat pump in colder climates ... of course, only down to the HP accepted outdoor temp level / b4 you need to use the ducted furnace.

We bought the 2015 specifically to get the ducted air conditioning. We had our first chance to use the heat pump this morning. It works well and is also quiet.

I'm having the same issue with the temp sensor. I hope that's the problem. I'm not happy they installed it behind the TV, next to the outside wall, and the frig vent works are just behind it. All those are heat sources. It's always reads about 7 deg higher than the bedroom.

As we did, too. Crazy to think that we traded off a perfectly good unit ...enticed by the sheer quiet of the ducted air ...

Some of us are just lucky. After having been talking for about a month with my dealer, I sold a Moho, then went back to order the new unit. I was informed no 2014 orders were being taken, only 2015. And the price was up about $4,000. After a few weeks, some of the details came through, and I was thrilled.

Of course after the unit arrived, the test of the ducted A/C was quite a pleasant surprise being not only quiet, but the cool down with two units was about as quick as I had seen, like in a car.

Of course some slight changes will be made to the outlets over the bed, but I do not have a problem with this.

dcopps, I removed the cover, for the temp sensor and unsecured the wire from the wire clamp and pulled through about 1.5" and left the cover off.... now Zone 1 and 2 reads the exact same ambient air temperature. there is lots of wire, I am thinking about moving it. Just hard to find another place. I know in the summer it will read the heat from the interior aluminum siding, and next to the TV. Limited to that wall, thinking closer to the hall, however there is a vent just above that area. Will see what the dealer recommends, when I bring it for service next. Mark
