My contact, William, was awesome and worked with me to have my product delivered as quickly as possible. Would totally recommend e-trailers and will use them again in the future.



by:

The air box that you sent me had already been installed by someone. Whoever installed it had damaged the unit to the point of not being usable. They put the unit back in the box without using the original packaging that was enclosed. You for some unknown reason sent the damaged unit to me without proper packing. When I received the box I noticed that contents were loose and rattling around. After opening the box, it was obvious to me what had happened. I realize that mistakes are made, but this is inexcusable. I have requested a replacement unit and have been informed that it should arrive on Wednesday. I will be shipping the damaged unit back. Please don't ship- it to someone else.

I am sorry that you received the unit in such a condition. I can assure you that we will not be shipping that unit out to anyone else. I see that your new unit should have arrived by now. I would love to hear your updated feedback on your experience, and/or your thoughts on the product.



by:

Quick delivery , fair price and great product . Easy install and works fine. I will recommend etrailer to everyone!



by:

Me thinking that the distribution box with the the thermostat was a remote. When I received it I called in and the fellow was very helpful got me hooked up with the unit with the controls on the box and when it arrived and I opened it that's when all hell broke loose. The 1st thing I noticed was the metal part was bent pretty bad, but me being an old body man I'm thinking hammering it out, well that was the 1st mistake , then after I installed that part, installing the cover should of been child's play but that's when I wished I would of sent it back, but no. The main and most concerning issue is, after installing the cover went to install the knobs and that's when I seen yet another issue, both of the switch shafts where bent,upon further inspection the shaft on both switches has been pushed into the switch,the knobs would not stay on so I had to glue em on. At this point it is installed and working OK but it is not rite. I do understand should of sent it back but I was determined to get it installed for an upcoming race. Do as you wish with this info.O' the case itself has a Crack in one corner.

That does not sound like a lot of fun. Customer Service will be in touch with you to work something out.



by:

Exactly what was advertised. Saved some money compared to the other options and installation was easy. I replaced a 20 year old Dometic and it was done it about 30 minutes.



by:

Very fast delivery time. Excellent packaging to help prevent damage during shipment. Haven't installed parts yet but everything looks good.



by:

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.

The best unit I ever bought. Do recommend this unit. Will buy again if my old unit dont function.



by:

Exactly as advertised, installed myself. If you aren't doing business with etrailer, you get what you deserve.



by:

I am very pleased with my order. The AC works very well and customer service was outstanding. Paula at etrailer went above and beyond to get my order shipped very quickly. I have told all my friends about her and etrailer and would highly recommend them to anyone shopping for rv parts.



by:

Fantastic, easy install on standard vent fan opening 14” x 14”. Outside unit installed easily. Some minor adjustments for interior AC control unit.



by:

Everything went together well. The instructions said to tighten the mounting bot to 50 inch pounds, but the gasket didn’t squash down to the half inch they specified. I just tightened as much as I dared and everything sealed up okay. We installed the soft start capacitor with the new AC unit, and it was all way cheaper than any other option out there for a new unit.



by:

I recently installed the Advent AC unit. Am very pleased with the unit. Camping last week with temps as high as 33 C and it kept our motorhome very comfortable. Also, thanks to the staff that helped me. Very pleasant, helpful, and knowledgable.



by:

All arrived in good shape. A little mysterious for installing the capacitor with two black wires to connect.



by:

Very nice unit. I replaced an old year 2010 unit on my RVision Trail Sport 28 ft. travel trailer. It fit the opening the roof with no problem, but I had to do a little adjusting on the inside of trailer. If your handy with small tools and good mechanical thinking ability this unit will work fine. Nothing is simple for all situations. I'm do it again. Once in,woks great!



by:

The distribution box assembly was very strait forward. we had to extend the air plenum, purchase long nuts, and 3/8 bolts because the roof was 6 inches thick. otherwise, the installation went very well!



by:

DOA. Had to pay money to a RV repairman to prove it was defective. Never got reimbursed.

I am so sorry to hear that this arrived DOA. I do see that per ASA, if an item arrives DOA on arrival, then it needs to be replaced. It seems that they wont have any replacements any time soon. We should be having some in our stock by the end of the year. Please let me know if you would like to wait for a replacement or if you would prefer to have a refund and return issued.



by:

I got my order today as you said I would. It is the exact parts I needed and ordered. There was no damages. Tjanks folks! Yall helped me alot. I will be ordering again from you folks.



by:

This fit our older Weekend Warrior toy box perfectly. Over the years we have encountered things that are not available for our older model. This fit PERFECTLY. I measured the opening, looked up the item and bought it in December 2021. It sat for four months until we were able to install it. We took out the old one, put in the new one (it was pretty easy to put in, harder to get it up on the roof), plugged it all in and it worked perfectly. It was getting hot (Arizona) and we live in our RV full time. It started working right away and stayed on 7/24 until Sept. Everything went to smoothly! We have bought from eTrailer before and they've been great. Will use them again.



by:

Works great



by:

The product was very comparable to what we replaced and works fine.I've used this company 3 times within the last month and they have the right products.



by:

I have had this for a year and I am a full-time RVer. So far this unit has met or exceeded my expectations.



by:

Good customer service and product arrived as scheduled.



by:

Terrific personal service, delivery ahead of schedule, great product!

  • 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 only)...

  • Can you Replace A GE ARC Air Conditioner With The Advent Air RV A/C
    Yes you can replace your GE ARC with the Advent Air RV Air Conditioner - 15,000 Btu - White # ACM150. You will also need to replace the thermostat. I suggest going with the Air Distribution Box w/ Built-In Thermostat for Advent Air RV Air Conditioners - White # ACDB

  • 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.

  • Will Existing Thermostat and Distribution Box From Coleman Mach Work with Advent ACM150
    We actually have an adapter that will allow you to use the Advent Air RV Air Conditioner part # ACM150 with your existing wall thermostat and distribution box, the Coleman Mach Adapter Wiring Kit part # ACCOLKIT which also makes for a plug-in play install. If you for some reason wanted to replace the distribution box and wall thermostat for the overhead unit you would just use the Air Distribution Box with Built-In Thermostat part # ACDB instead of the adapter kit. That said, I recommend...

  • Recommended Heat Strip and Air Distribution Box for a Advent 13.5K BTU A/C Unit and Propane Furnace
    The Electric Heat Strip for Advent Air RV Air Conditioners item # ACMHD can be used with your Advent 13.5K BTU set up but you won't be able to control it with your wall thermostat. You will need the Air Distribution Box w/ Built-In Thermostat for Advent Air RV Air Conditioners item # ACDB to control the heat strip.

  • 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.

  • Recommended Replacement For A 13.5K GE RV AC Unit
    We recommend the Advent Air RV Air Conditioner # ACM135 to replace the GE 13.5K RV AC unit. The advent unit has the same 13.5K BTU rating. You will also need a new distribution box and/or thermostat. You can use # ACDB for manual control or the # ACRG15 which comes with a wall mounted thermostat. Advent sells their start capacitor # ACMSCKIT separately, and we do recommend picking up one of those as well. You also have the option of adding a heat strip # ACMHD.

  • 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. If you are trying to use an existing ceiling vent and thermostat then please let me know what that is as there may be an adapter for...

  • Recommended Advent Air Replacement For A Dometic Duo-Therm AC System Model # 59036.501
    I spoke with Dometic and was able to determine that your model is a 1st generation 15,000BTU unit. The tech couldn't tell me if there would be a 6-pin or 9-pin connector for the rooftop unit and was unsure that a new unit would actually be able to communicate properly with the controller and thermostat. The Advent Air Replacement RV Air Conditioner for Dometic Setup # ACDOM150 you were looking at comes with a 6-pin connector and could possibly work with no issues but there's still the...

  • Will The Advent Air Replacement Rooftop Unit Work With A 2-Speed Dometic AC System
    Since the Advent Air RV Air Conditioner # ACM150 is only replacing the rooftop unit and the "brains" would be the controller and thermostat you'd most likely be losing the medium setting since the Dometic only has a hi and low speed functions available. The connection point on the controller can be either a 6-pin or 9-pin. if your controller requires a 9-pin connector then you would also need to pick up the # ACCOLKIT adapter to connect to it. If you are wanting to get the best performance...

  • 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.

  • Does the Advent Air Roof RV Air Conditioner ACM135B Come with the Ceiling Control Panel
    Advent Air Rooftop RV Air Conditioner # ACM135B is just the outside part of the air conditioner. For the inside, ceiling portion you could use # ACDB.

  • 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.

  • Air Distribution Box For Advent Air Conditioner
    There are two air distribution boxes for the Advent Air conditioners that we offer. Both have thermostats however, one is a wall mounted and the other is built in. I recommend the Air Distribution Box Item # ACDB which has a built in thermostat and controls on the plenum.

  • 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.

  • 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 and...

  • Will Fan Keep Running for Air Distribution Box w/ Built-In Thermostat
    The Air Distribution Box w/ Built-In Thermostat for Advent Air RV Air Conditioners # ACDB will keep the fan of the Advent air conditioner running but only the fan. When the thermostat sees the temperature raise above the desired setting then it will kick the compressor back on so the cooling feature will start up again. This is actually an industry standard when it comes to RV air conditioners.

  • 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.

  • Recommendations For Adding AC To A 14 X 8 Enclosed Trailer
    We can definitely help set you up. For a 14' x 8' enclosed trailer, I believe a 13,500 BTU unit would be sufficient. I recommend the Advent Air # ACM135. Advent makes a solid AC unit, which will fit perfectly in the 14" hatch on the roof. Keep in mind the roof does need to be between 2-1/2" and 5" thick in order to install this unit. As far as your controls, you have two options. You can either use a manual distribution box # ACDB, which will put your controls on the ceiling right above...

  • 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...

  • How To Make An Advent Air Heat Strip Work With An Advent Unit In A Dometic System
    If your Dometic controller doesn't have a port for the Advent Air Heat Strip # ACMHD to plug into then the only way to make it work would be to swap out the air distribution box/controller with either the manual control # ACDB or wall control # ACRG15. This would give you a compatible controller for the heat strip to plug into and would essentially fully swap you over from a Dometic system to an Advent Air system.

  • Troubleshooting Coleman Mach AC Controller Shutting Off Advent Air Conditioner After Update
    This sounds like an issue with the Coleman thermostat/controller. I would recommend changing to the Advent which we have either a Manual Air Distribution Box # ACDB or Thermostat Air Distribution Box # ACRG15.

  • Second AC Unit for 2020 Keystone Cougar 29RLKWE
    For an air distribution box for the Advent Air part # ACM150 that has a build in thermostat and controls you'd want the part # ACDB. While we don't have an install video for this unit on your exact RV I attached an install video for this setup on a similar RV that covers the process.

  • Is There A Remote Thermostat Available For An Advent Air RV Air Conditioning System
    Hey Brad, The comment was referring to the Air Distribution Box w/ Wall-Mounted Thermostat # ACRG15, which has a wall-mounted thermostat instead of the manual-control thermostat # ACDB he originally had. If you were referring to a remote control style thermostat then then unfortunately isn't one at this time.
