Can Furrion RV AC Unit Install in Whisper Quiet Duct System

Updated 07/30/2025 | Published 04/28/2025

Question:

My RV is a 2021 Keystone Montana that has the whisper quiet ducted A/C system. Currently have Coleman’s but looking to swap to furrion. Is there a chill cube that will fit my whisper quiet ducted system? If you’re unfamiliar with what that means, I don’t have to center air distribution box holes in my ceiling. I have 2 air return ducts, and all the normal ducts.

At this time none of the Furrion RV AC units can be installed on the Whisper Quiet duct systems.

Jameson, you said the Furrion is not compatible with the WhisperQuiet system. I have a 2016 Heartland with the same system. Could I have a hole cut in the ceiling for the distribution box and make it work with the existing ducts, or am I just stuck? My original Dometic just isn’t keeping up with the heat these days. What are my options?

@ErikaD We've heard of people making it work somehow but we don't have specifics on how to do that. I wish more AC companies had install info on that type of application but at this time we've only had GE tell us their low profile units (which we don't carry) can be used with a top down setup like yours.

@JamesonC Thank you for that information.
