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:

Works great,I wish I had gotten it with heat also,the air Works great.



by:

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



by:

very good communication fast shipping just as described great item



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:

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



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:

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:

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:

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:

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



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:

Awesome product and service.



by:

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



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 !!!!!!!



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.

It was easy to install and works perfect

  • 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...

    Thank you for your purchase of the Advent Air RV Air Conditioner System # ACM150C!

Check your air filter and clean it if it is dirty and clean up/repair any damaged wiring or connections.

  • Does Advent Air AC Unit Have to be Powered by a Generator
    AC units like the Advent Air RV Air Conditioner with Ceiling Vent # ACM150C draw quite a bit of current. For example this one draws 1,750 watts at 115 volts. This would be too much draw for the electrical system of your 1999 Ford F-450 and also not the correct voltage since your vehicle is a 12 volt system. You also have to consider that you'd be most likely running this when the vehicle isn't running which would kill the battery very quickly. Something like the # 289-AP5000 should be...

    If you're wanting a higher capacity air conditioner for your concession trailer, a 15K unit like the: -Furrion Chill Replacement RV Air Conditioner for Furrion Setup # FR86PR is the largest size offered in the industry. Your best bet is to add an additional air conditioner Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor # ACM150C.

  • 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.

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...

You can always go with a higher BTU rating than what your system is but you wouldn't want to go lower.
