Good product , works well . Used to replace an old carrier air v unit .
Fit in existing hole with no issues . Only problem was from ups shipping box was damaged and unit arrived upside down .



by:

The A/C unit we got a couple weeks ago for our mothers RV... was good.
The interior cover with controls was really flimsy and had very sharp edges.
But it's in and works.
Thank you.

Do you have a question about this Accessories and Part?
  • Will Advent Air Distribution Box ADV48SR Work With Advent ACM135
    Hello Dennis, thanks for reaching out. The Air Distribution Box # ADV48SR will work with any of the 2025 or newer Advent AC units that use the new R32 refrigerant. The part in your picture appears to the Advent ACM135. This part number is an older unit that uses the old R410a refrigerant. If this is what you have, this would not be compatible with the # ADV48SR distribution box. The distribution box you would need is Advent part ACDB, but sadly this was discontinued when they switched...

  • What Manual Control Distribution Box Goes With Advent Air RV Air Conditioner ADV86SR?
    Hey Dave, thanks for reaching out. We have exactly what you need! The distribution box you will need to go with the Advent # ADV86SR unit you ordered is the following: - Air Distribution Box w/ Built-In Thermostat for Advent Air RV Air Conditioners - White - R32 # ADV48SR This will give you manual controls for the AC right on the ceiling under the unit. I also recommend you add the Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT as this will help keep the startup amperage...

  • Availability Of Distribution Box For Older Duo Therm 59516.331 AC Unit
    Hello Kevin, thanks for reaching out. I am sorry to say we do not offer an air distribution box to go with that. Main reason being what you have is an older AC unit that uses the now discontinued r410a refrigerant. The new RV AC units and distribution boxes now use R32 refrigerant. The new distribution boxes are not backwards compatible with old AC units. So the only solution here would be for you to either find an old Duo Therm distribution box, or to use a new R32 AC unit and distribution box.

  • Air Distribution Box and Thermostat for 15K Btu Advent Air R32 AC Unit
    Hey José, thanks for reaching out! The air distribution box and thermostat that works with the Advent Air RV Air Conditioner # ADV86SR you're looking at is part # ADV98SR for a wall thermostat, or part # ADV48SR if you want the thermostat built into the air distribution box. Let me know if you have any other trailer upgrades or replacements you plan on doing in the future and I'll be happy to help you out!

  • Does the Thermostat in the Advent Air Distribution Box Turn On an Off When It Reaches a Temperature?
    No, the Air Distribution Box w/ Built-In Thermostat item # ADV48SR turns on and off when it reaches a certain temperature inside the trailer. This one is exclusively for Advent ductless systems with R32 refrigerant. What AC Unit are you looking to install the item # ADV48SR on? This system has the new R32 refrigerant in it and is not compatible with any AC built before 2025 that doesn't have the new R32 refrigerant, including Advent ones. You can add this information and any other questions...

  • Does Advent Air AC Unit Vent Assembly Fit Older Advent Air Units
    Hey Noe, the Advent Air Ceiling Assembly Air Box part # ADV48SR that you referenced will only work with Advent Air AC units that were made after January 1st of 2025 due to changes in the refrigerant requirements that were enacted on that day. If you have an Advent Air unit made after that day then yes this would work but if old we don't have a solution.
