This Advent Air AC unit lets you replace an existing, old or broken air conditioner or add a new air conditioner to an area on your RV or camper that doesn't already have one. The AC has a powerful fan and motor that provides a steady stream of air to efficiently cool the inside of your RV on a hot or muggy day. For your convenience, the included air distribution box has a built-in thermostat that lets you set the fan speed and temperature. The included start capacitor will help jumpstart the AC. This beneficial upgrade provides the AC a boost when shore power or generator power isn't enough to start it. And everything you need in order to replace or add an AC unit is included, which makes installation simple and easy.


Air Distribution Box and Thermostat

Advent Air Air Distribution Box

The AC unit includes an air distribution box with a built-in thermostat. The dial on the left controls the 3 cool settings and the 3 fan speed settings, which let you increase or decrease the airflow. If you add an electric heat strip (sold separately) to remove the chill on cold mornings, then the dial also controls the heat setting. The dial on the right allows you to set the temperature. Additionally, there are adjustable registers on the front and back of the box. These can be tilted up, down, or side-to-side for directing the air where needed. The removable air filter prevents dust and dirt from building up on the fan blades.


Start Capacitor

Advent Air Start Capacitor

If your campsite or generator isn't able to draw the power you need, then you may have difficulty starting your AC unit. The included start capacitor, however, can eliminate this problem. The capacitor stores energy that will later be used to jumpstart the AC. Once the sufficient amount of power has been supplied to the AC, the compressor will start to run, and the internal relay switch will turn the start capacitor off. At the same time, the compressor will send "back voltage" to the relay switch and capacitor in order to energize them for the next startup.


Simple Installation

Advent Air AC Installation 15,000 BTU

Because your RV is likely already prepped and pre-wired for an AC unit, installation is simple and easy. Most AC units, including this one, are designed to fit an opening that measures 14-1/4" x 14-1/4". Depending on your roof setup, you may need to do minimal alterations. If the opening is larger than 14-3/8" x 14-3/8", you will need to install spacers between the sides of the unit and the opening's edges. If the opening is smaller than 14-1/8" x 14-1/8", you will need to enlarge the hole to fit the unit snugly inside the opening.


Advent Air AC Collapsible Gasket and Foam Pads

On the bottom of the AC, there's a thick, collapsible gasket with 6 noise-reducing foam pads. This provides support between the RV roof and AC and seals the opening to prevent water and outside air from leaking in. Because of this, the use of fresh sealant isn't required during installation.


To install the start capacitor, bolt it to the fan motor support with the included hardware and then route the wires to the run capacitor.


Once installed, the hard plastic cover on the AC can easily be removed for maintenance and cleaning.


Advent Air Warranty Coverage

2-Year limited warranty covers defective units when installed correctly on approved applications. The warranty does not cover units installed incorrectly. To ensure air conditioner is installed correctly, please see the questionnaire pdf below. A filled-out questionnaire is required for warranty coverage.


If you are not comfortable using a voltmeter (or removing the charge from the start capacitor), youll want to make a service appointment with your local RV dealer to verify the installation. Print the pdfs below (warranty- questionnaire, warranty dealer information) and take them along with the RV to your local dealer. ASA does compensate dealers for warranty work as outlined in the dealer information pdf. You may be charged by the dealer for time spent investigating the installation.

First when ordering Jamie was very helpful and was able to answer my questions. I received my order actually one day ahead of schedule. But once I opened the box the unit was damaged. But I had mine off and a hole in roof so I opted to keep it and install. The unit was very easy to install and went together well. It is not any louder than my old unit. It looks very nice. And seems to work just as advertised. I am very pleased. I did email e trailer about the damage and they got back to me very promptly. We reached an agreement and again I’m very pleased at this point.



by:

Seems to run as advertised. Popped the circuit breaker, once. My biggest issue was shipping damage because of the poor packaging. Basically, a cardboard box with the unit unprotected inside. Three units were delivered, all damaged in shipping. I was able to piece together one good unit from all the broken or dented parts, and ship back the damaged goods. The units need to be packaged better to avoid the damage and hassle.



by:

The AC is perfect for our motorhome.



by:

While we had it, there were no issues. Worked great. RV has been sold since.



by:

I purchased the 15,000 btu model
Shipping
was fast the unit works fantastic installation was pretty easy my trailer was preset up,you definitely need the hard start capacitor as my 4500 watt generator starts it but wouldn’t without it I also purchased the heater strip that is all the pros the only con is the 2 knobs that control pop off once in a while so I glued them on definitely would purchase again



by:

etrailer.com did they job delivering it on time, good packaging and working properly.

This equipment does a good job, in the trailer is always way cooler than outside, but I still wish the AC Unit was a little more powerful. I won’t complain though, it was definitely a cheaper equipment. I could have spent a lot more in a different unit.



by:

etrailer shipping was prompt, we received exactly what we ordered. The Advent AC was as expected, a plug and play unit. Out of all the other work we've done on our 2000 trailer, installing this unit was one of the easiest. The unit works great, at times its too cold. And its def quieter than our 2000 unit. Overall I recommend it and easy to DIY.



by:

Etrailer was very easy to deal with. Prompt responses to queries..email updates on shipping and delivery. Delivered ahead of schedule. But box was damaged. Unit had damage to exterior. They promply provided us with resolution options. Would definitely deal with etrailer in the future.



by:

Came faster than expected. Installation was easy. Works great.



by:

Keeps the horse trailer really cold during the 100 plus degree summer, Only thing is when it rains it leaks but that could have also been user error when installing it. We had to replace our old AC since it quit working on us and this one is doing the job really well.



by:

An excellent replacement unit for an aging and unreliable Coleman unit. My only issue is it sometimes, under heavy load, trips the 20 amp circuit breaker it is being supplied from.



by:

always awsome dealing with e trailer th nx!!!!



by:

This a/c is very quiet, efficient and effective. The heat pump reduced my propane use dramatically.



by:

Awesome product and service.



by:

The advent air conditioner is very quiet and works great. It was also easy to install.



by:

Works great in my race trailer



by:

Great customer service. Noah was very helpful and I received all the parts timely and thanks to Noah the install was easy!



by:

Received product on the day promised. Product had a little damage from shipping. Don't think it will affect the ac working properly. Haven't installed yet. Planning on it this weekend. Will follow-up. Ac seems to be better made and heavier duty than the original.



by:

Sent wrong parts , but Reesa in customer service quickly rectified the problem and shipped proper stuff.
Awesome team of people.
SPECIAL THANKS TO REESA !!!!!!!

It was easy to install and works perfect

  • Replacement Distribution Box Needed for Carrier RV AC
    The model number you list is for the Carrier Air V, it is no longer produced. We do not have the replacement part you request available. If you want to consider replacing the entire unit, I suggest the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor, 15,000 Btu, # ACM150C. This is a complete set-up with a start capacitor that allows for easier start ups and assists with generator starts while boondocking.

  • Recommended RV Rooftop AC Unit with Ceiling Vent and Controls
    Great question. We do have the Advent Air Rooftop RV Air Conditioner # ACM150 with the interior components. It is part # ACM150C and it also includes the start capacitor. That capacitor is extremely helpful in making sure you can start your AC even when the shore power isn't able to draw that capacity. The capacitor will automatically refill to ensure you never have an issue starting your AC. The vent assembly has a built in thermostat to control fan settings and temperature. There...

  • Recommended Replacement for Dometic Duo-Therm RV Air Conditioner
    We do offer a direct replacement for the Dometic Duo-Therm RV Air Conditioner. The Advent Air RV Air Conditioner part # ACM135 for 13.5K or part # ACM150 for 15K is what I recommend. This unit will be a plug and play fit and it will work with your existing thermostat. If you replace the thermostat you're looking at an entire new system and this will require wiring so unless yours no longer works I recommend keeping it. The complete system is part # ACM135C for 13.5K or part # ACM150C...

    Yes. The white version of the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor - 15,000 Btu - Black # ACM150BC is part number # ACM150C. This is the exact same unit you were looking at, which is a non-ducted unit, only white in color to match your RV.

  • Can I Install Advent Air Conditioner In Skylight Cut Out On Travel Trailer
    The Advent Air RV Air Conditioner part # ACM150C installs into a 14-1/4" long x 14-1/4" wide roof opening. If you remove the skylight and the opening is smaller than 14-1/4" long x 14-1/4" you can carefully cut the opening to make it larger, however it is recommended to install the unit slightly forward of the center of the center of the roof and centered from side to side. I have attached diagrams from the installation instructions for your reference.

  • Troubleshooting Advent Air AC Unit Shutting Off During Runtime
    Thank you for your purchase of the Advent Air RV Air Conditioner System # ACM150C! When it comes to troubleshooting you want to start off with the easy things like the air filter and your wiring connections. Check your air filter and clean it if it is dirty and clean up/repair any damaged wiring or connections. If all of that looks good then move on to see if the unit is freezing - if the AC unit is freezing then you need to wait for it to thaw out. If all of this looks good then you...

  • How to Determine the AC BTU Rating Needed to Cool an Enclosed Trailer
    Based on the square footage of your 28 foot utility trailer the minimum BTU rating you'd need from an AC unit would be 4,760. So the Advent 15k BTU unit part # ACM150C would easily handle cooling your trailer. There'd be no need to add a second unit. To determine how much BTU is needed for a trailer you take the square footage and multiply it by 20 btu and that's the minimum needed.

  • Recommended AC Unit for 26 Foot Enclosed Trailer
    To cool down your 26 foot enclosed trailer I highly recommend the Advent Air RV Air Conditioner # ACM150C, which includes both the air distribution box and a start capacitor as well. The start capacitor in particular is a great feature that basically stores up energy to use for when the AC kicks on, conserving energy and reducing the amount of power needed from your batteries or inverter. The AC unit uses a 6-blade fan with motor to increase/decrease airflow, a built-in thermostat that...

    With no ceiling assembly on your 2017 Forest River Rockwood Signature Ultra Lite Travel Trailer RV, it sounds like you might have a ducted system. The Advent AC unit part # ACDOM150 that you referenced will work great as a replacement for a Dometic Duo Therm unit that you have and can actually be used as a ducted or non-ducted unit since this is just the vent assembly. The ceiling assembly, which is not included, is really what determines a ducted or non-ducted setup. If you had a ceiling...

  • Picking Out Replacement AC Unit for 2015 Jayco Jayflight 26BHS
    I don't know what unit you have on your 2015 Jayco JayFlight 26BHS but if it happens to be a Dometic the Advent Air Unit part # ACDOM150 that you referenced was designed to easily replace Dometics so it would be a really great solution. It uses wiring connectors that would plug right in and allow you to use your current thermostat. Otherwise the part # ACM150C is a really great option that comes with a start capacitor and an air distribution box.

  • What is Needed to Install Air Conditioner in Enclosed Car Trailer
    We can get you the air conditioning you need to keep cool in your enclosed car trailer; what you will need is a ductless AC unit with a distribution box that will control the unit as well as blow the air in, as well as a generator for a power source (if you don't have one). I highly recommend going with a 15,000 Btu AC because of its additional cooling power which will cool your trailer down quicker, especially with a 24 foot trailer, though I will list the options for both the 13,500...

  • 15,000 Btu Ductless Air Conditioner For RV With Thermostat
    There is an option for a 15,000 Btu ductless RV air conditioner that does not have a wall-mounted thermostat, though there aren't any with a wireless thermostat. What you can use is an option from Advent, which has the thermostat directly on the distribution box so you don't have to use one mounted on your wall. This is available in either white or black: - White: Advent Air RV Air Conditioner with Air Distribution Box and Start Capacitor # ACM150C - Black: Advent Air RV Air Conditioner...

  • AC Unit Recommendation for 32 Foot Enclosed Trailer
    AC unit BTU ratings typically call for 20 BTU per square foot. So for a trailer that is 32 foot long and most likely 8 feet wide you'd have 256 square feet to cool. That means you'd need a minimum of 5,120 BTU to cool it effectively. So the 15k BTU Advent # ACM150C that you mentioned would be way more than you'd need but it would cool the trailer very quickly. Another option is the 13.5k Advent part # ACM135CH which comes with a vent box, a heat strip (provides heat if needed), and a start...

  • Replacement For Carrier Air Conditioner and Air Distribution Box
    I recommend replacing your Carrier air conditioner with the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor # ACM150C.

We do not have a direct replacement for your air distribution box.

    Yes, the 13,500 Btu Advent Air RV Air Conditioner with Air Distribution Box and Start Capacitor # ACM135C (White) or # ACM135BC (Black) will cool your enclosed trailer. These are ductless systems as I assume your trailer does not have ducts. That said, it will essentially need to always be on so you do need to monitor your generators and be sure they are full.
