Love this product. I bought this to replace my carrier a/c unit because my thermostat wasn't working properly Boy, does it blow out the coldest air. I would recommend this product to anyone. Made the right decision, would buy again in the future.

Wish they made a vented distribution box with a propane heater set up like my old Carrier AirV had. But I went ahead and changed everything out. At the very least my trailer is much cooler now.

easy install, cools awesome but was hoping it would go off and on like wall thermostat did since it has a built in thermostat

by:

The ASM 150 is great. Strong, quiet, very easy to install. Only wish it had a thermostat you could set and forget instead of having to keep babysitting the dials. Etrailer far surpassed my expectations and delivered parts so fast they didn't even have time to forward me the tracking number. Price was a tad higher than competition but free shipping equaled it out.

  • Replacement Advent Air Conditioner for Ductless DuoTherm Air Conditioner
    I spoke with a representative of Advent, who told me the Air Distribution Box with Built-In Thermostat for Advent Air RV Air Conditioners # ACDB will only work with the Advent brand of air conditioners. So if your ductless DuoTherm distribution box is not working you can replace your entire unit with an Advent set up, which includes the distribution box and thermostat.

  • What All Is Needed To Install An Advent Air Rooftop RV Air Conditioner ACM135
    In order to install the Advent Air Rooftop RV Air Conditioner part # ACM135 you will also need a ceiling vent and thermostat. If you have a non-ducted trailer then you can use the Ceiling Vent Assembly with Built In Thermostat part # ACDB but if you have a ducted trailer then you will need the Ceiling Vent Assembly with Wall Mounted Thermostat part # ACRG15.

  • Replacement AC Unit Compatibility with Old Air Box and Thermostat
    The Advent Air RV Air Conditioner - 15,000 Btu - White # ACM150 is designed to just replace the outside part of the AC system and utilize the old system components like the air distribution box, ducts, and thermostat. It is directly compatible with Coleman Mach or Carrier setups if used with an adapter wiring kit ( # ACCOLKIT or # ACCARKIT ) which are sold separately. It is directly compatible with Dometic systems without needing an adapter wiring kit. If you want a system that has...

  • Adding Heat Strip to Advent AC Unit that Does not Have Knobs on Vent Assembly
    To use the Advent heat strip # ACMHD with your current Advent Air RV AC unit you'd need to replace your current distribution box with the part # ACDB since what you have does not have knobs.

  • Recommended Air Distribution Box for Advent Air ACM135
    When it comes to roof top air conditioners, the air distribution boxes that are compatible with them are going to be fairly specific. The Advent # ACM135 is compatible with only 2 specific air distribution boxes: the Air Distribution Box and Thermostat # ACRG15 or the Air Distribution Box with Built in Thermostat # ACDB , so you would need to use one of those. You may also need some 12 gauge double wire # 12-2-1 and Heat Shrink Butt Connectors # DW05745-5 to complete the installation.

  • Does Advent Air ACCAR150 Replacement RV Air Conditioning Unit Include the Thermostat
    The thermostat is not included. The unit includes an adapter that would allow you to continue using your existing Carrier air distribution box and thermostat. If you need the air distribution box and wall mounted thermostat, it's available separately as part # ACRG15. For an all in one unit that has the thermostat built into the air distribution box, use # ACDB. I've linked to some product description videos for the air distribution boxes/thermostats I recommended above

  • Parts Needed to Install Advent Air Rooftop RV Air Conditioner # ACM135 in RV

  • Non-Ducted Air Conditioner for Food Trailer
    The Advent Air Rooftop RV Air Conditioner # ACM135B is actually just the outside part of the AC unit and wouldn't be considered either ducted or non-ducted but you're on the right track! What you need along with Air Conditioner # ACM135B - which is Black in color but also available in White at part # ACM135 - is Ceiling Vent Assembly # ACDB to give you a non-ducted AC unit. The vent assembly will install in a 14-1/4" long x 14-1/4" wide opening in your roof and will be inside your food...

  • Installation Instructions for Advent Air Rooftop RV Air Conditioner # ACM135
    There is not a standard plug available that would allow you to plug the Advent Air Rooftop RV Air Conditioner # ACM135 right to an extension cord. The unit will need to be hardwired using the included wiring and hardware. I have attached the complete installation instructions that you can use for reference. To complete the installation you will also need a ceiling vent and thermostat like part # ACDB.

  • How to Determine if Advent Air Conditioner Will Fit Trailer
    It is highly likely that you can use the Advent AC where the vent is now on your car trailer, though we do not have any specific blueprints or diagrams or any way to know the size of your trailer's vent opening. In order to use the Advent Air Rooftop RV Air Conditioner # ACM135 (White) or # ACM135B (Black) you would need the Ceiling Vent Assembly # ACDB and these will fit a roof opening of 14-1/4" long x 14-1/4" wide, which is the standard size opening for trailer vents so it is very...

  • Does Advent Air Rooftop RV Air Conditioner # ACM135 Come with Heat Strip
    The Advent Air Rooftop RV Air Conditioner # ACM135 doesn't come with a heat strip directly but you can add one with part # ACMHD. This is a great combination that can be controlled by the Ceiling Vent Assembly # ACDB. Attached are some installation videos for you to check out as well.

  • Ceiling Vent Assembly for Advent Air Rooftop RV Air Conditioner

  • Can I Control the Heat Strip on Advent ACM150 Unit with Carrier Air V Controller
    It sounds like you're trying to control the heat pump on your Advent # ACM150 with your existing thermostat, which is not possible, but I do have a solution for you. The Carrier remote does not have a heat function on it, so there's no way for your existing unit to control the heat function. The Electric Heat Strip for Advent Air Conditioners # ACMHD can only be operated with the Air Distribution Box w/ Built-In Thermostat for Advent Air RV Air Conditioners - White # ACDB (non ducted...

  • How To Use the Advent RV Air Conditioner To Replace a Carrier Air V Air Conditioner with Heat Pump
    Correct, the Carrier Adapter Wiring Kit for Advent Air RV Air Conditioners part # ACCARKIT will not work with Carrier Air V RV Air Conditioner if it has the heat pump. Since you do have the heat pump you will need to replace the distribution box as well with the Air Distribution Box w/ Built-In Thermostat part # ACDB.

  • Replacement Ceiling Vent Assemblies for an Advent Air Conditioner 135 Unit
    If by replacement fan and motor you mean the Ceiling Vent Assembly # ACDB for non-ducted or # ACRG15 for ducted RVs then we carry those as the above mentioned part numbers. These are compatible with the Advent Air Rooftop RV Air Conditioner # ACM135. We don't carry any replacement grommets or mounting hardware for any of our Advent units so you would need to source that elsewhere. The closest thing that you may have meant by grommet is a seal like part # A10-1414 which is 3/4" thick...

  • Does the Advent Air Roof RV Air Conditioner ACM135B Come with the Ceiling Control Panel

  • Can Advent Air Replacement RV Air Conditioner Replace 2-Speed Duo-Therm 57915.531 AC Unit
    I spoke with my contact at Advent who said that as long as you have a newer system the Advent Air Replacement RV Air Conditioner for Dometic Setup # ACDOM135 should work just fine even if you only have high-low speed settings for your fan. If you don't have a newer system then you can replace your vent assembly and thermostat with a kit like part # ACRG15 which is for ducted units or # ACDB for non-ducted units.

  • Can Advent Air Conditioner Unit # ACM150 Fit Pop Up Camper
    The AC unit part # ACM150 that you referenced can be used on a pop up camper. It is designed to fit the very standard roof vent opening 14-1/4 by 14-1/4 inch like what you most likely have. The thermostat and vent side of this is part # ACDB that you'll need as well.

  • Is a Ceiling Vent Assembly Required to Switch from Carrier AC to Advent Air AC on a Keystone Outback
    Whether your AC system is ducted or non-ducted there will be a ceiling unit. You would not have to replace the ceiling unit that you already have if you are just switching out the outside air conditioner that sits on the roof. If for some reason you do not have a ceiling unit inside the trailer then you would need one, # ACDB, to switch air conditioners to Advent Air Replacement Rooftop RV Air Conditioner for Carrier Setup # ACCAR150.

  • AC for Fleetwood Motorhome
    The Advent Air Rooftop RV Air Conditioner # ACM135 is not vehicle-specific; it will fit in a standard 14-1/4" x 14-1/4" vent opening. It will require separate controls and wiring. To install the unit you also need the Ceiling Vent Assembly with Built In Thermostat for Advent Air RV Air Conditioners # ACDB.

  • Best & Most Efficient Replacement For Carrier Air Conditioner
    We can absolutely get you set up with a replacement for your Carrier air conditioner, and the best, most efficient option is from Advent. I highly recommend going with the 15,000 Btu unit for the most cooling power, and you may not even need a new distribution box if your Carrier's is working fine. I say "may" because the adapter needed that makes the AC compatible with your Carrier's air distribution box is not compatible with Carrier units that have a heat pump. To make it simple,...

  • Air Conditioner for 8' X 24' Enclosed Trailer
    The Advent # ACM135 is a roof top air conditioner unit that puts out 13,500 BTU of air conditioning power. This is the roof top portion only. You will also need the Advent # ACDB inside air distribution box with built in thermostat. Together this would be very good for a 24" trailer. I have a 21' travel trailer and the 13,500 BTU air conditioner gets the trailer very cool. This unit draws 15 amps of power when running, so you will need to wire this unit with at least 12 gauge wire...

  • Which Lower Vent Distribution Box for Advent Air RV AC Unit
