Question:

I need a replacement for my Duo-Therm 57915.541 AC unit

I recommend using a 13.5K Btu Advent Air AC unit to replace your Dometic Duo-Therm 57915.541:

- Black # ACDOM135B
- White # ACDOM135

These will just plug and play into your current wiring (if you have the pictured 6-pin connector) and carry the same ratings as your current unit so the function will be comparable.

What is the efficiency rating of the 13.5 btu advent ac?

@RobertS We don't have efficiency ratings for our AC units, but if there is a specific spec you're needing to know about I'd be happy to look into it for you!

@SarafaA This answer is a bit older and some things have changed. Right now, you'll have to get a whole new AC system as there aren't any units that are plug and play like there used to be. For your application I recommend going with the Furrion Chill HE R32 which comes in White # FR35TD as well as Black # FR25TD. These come with the AC, a thermostat, and the plenum that mounts to the ceiling inside so they will be a complete package to replace what you have. Would you want to stick with the 13.5K Btu units, or are you wanting to upgrade while you're at it?
