Dual AC - which is which?

[jayseejay]

Hi, I just took delivery of a 2015 27' EB FB Twin with dual AC. I know zone 1 is the unit up front, but does anyone know how to determine which unit is 15,000 and which is 13,500? From the exterior cowling, they look identical (to me). Thanks in advance!

Logically, the front unit would probably be the 13,500 BTU unit as the bedroom is a smaller volume to cool and the 15,000 BTU unit would be for the larger kitchen/dinette area.

In the case of our Classic with rear bedroom, the smaller unit is in the back for the bedroom.

Check the single page equipment listing for your trailer that you signed when taking delivery. The model numbers of the two air conditioners will be listed and can be checked on line to verify that there were two sizes installed.

Hi, We also have a 2015 27 FB EB with the dual A/C's and the larger 15,000 BTU Unit is Zone 2 which is the rear A/C in the living area.

Thank you both for your help! Best, Joe

Zone 1 is where the Dometic Controller is located

My Zone 1 is the rear of my 2015 Serenity 30RB

You probably can't tell by which unit blows and cools the most. I had two 13,500s installed and the rear bedroom unit will blow you out of bed if you don't deflect it away from your head. I am thinking about a Home Depot plastic deflector to go behind the rear of the bedroom outlet over the head of the bed. From reading the above posts I would guess the large unit are installed in the living room.

In my Classic, the control is in the dining room and is Zone 1.
I have been in a Flying Cloud with the controller in the bedroom as Zone 1 and the living room as Zone 2. So, I conclude that Zone 1 is where the thermostat is.

Zone 1 is where the Thermostat resides as deducted. 15k is den and 13.5k is bedroom. For 2015 ductless models JC will sell you round A/C vents with adjustable flow control. (Std in 2016)
