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. It also operates the electric heat strip, which helps keep you warm on a cold morning. 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 fan speed settings, which let you increase or decrease the airflow. It also controls the 3 cool settings and 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.


Electric Heat Strip

Advent Air Electric Heat Strip

The electric heat strip keeps your RV warm on a cold or frosty morning. It is operated with the control dial on the air distribution box. After you turn the dial to the OPT. HEAT setting, the compressor will shut off, and the fan will blow air over the heater and into your RV. When the optimal temperature has been reached, turn the dial to a fan or cooling setting. Please also note that the heat strip only has one temperature setting and cannot be controlled by the thermostat.


Simple Installation

Advent Air AC Installation 13,500 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.


To install the heat strip, mount it to the evaporator inside the AC unit with the included mounting screws. The heat strip has easy, plug-and-play installation with the supplied 30" power cord. Please note that the heat strip should be installed before the air distribution box is installed.


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

I'm planning on using my trailer as a workshop so heat and AC were important. This AC unit was easy to install into the existing 14x14 vent. Took me about an hour to install and everything went smoothly. My trailer is 28 ft long so I'm thinking that I'll be needing a 2nd unit at the far end. I'll decide that after I'm finished insulating the walls. I've already put in 2 inches of rigid foam on the roof and that alone made a huge difference. 655942


Comments
AC works well but I recently upgraded this unit to the remote thermostat so that I would have more precise temperature control. Upgrading was easy just bought the part from etrailer and installed. I definitely do need a 2nd unit which I hope to do soon.

As with other orders, the generator showed up on time and in good shape. The etrailer videos were very clear as to remove the old AC and replace it with the new Advent unit. The etrailer videos also showed to install the capacitor, the heat strip, and the distribution box. We were worried about getting the unit on the roof of the camper however it really was not a problem ….. we leaned a ladder up against the camper, tied a rope around the box, then leaned the box against the ladder. One person got on the roof and pulled the rope while two more people pushed from below... no problems and in about a minute the box was on the roof. The unit is now installed and looks good …. no power at the storage yard so I can only assume that the unit works as it is supposed to (like ever thing else we have ever ordered from etrailer). Good Job guys! 644424

Being from Hawaii could have is disadvantages when trying to get items shipped here. Thanks to Dena from etrailer my customer as well as myself are very happy. My customer was specific to what type of product they wanted because they were very pleased with it in the past and gave me the task of finding it and getting it shipped here. After a few failed attempts from other vendors Dena not only came through for me but expedited my shipment and saved me close to $500.00 in air freight charges. Thank you Dena and her team for the great service!!. I look forward to doing business with etrailer in the future. 707862

Installed on used short school bus, partially converted to an RV. The unit was relatively easy to install. It looks good and runs great, however I should have bought a larger unit. The interior of the bus is approximately 150 square feet so I thought 13500 btu would be more than adequate. While it does not quite keep up with this Louisiana heat, it is much better with it than without. The bus did not come with factory ac, so I installed a generator on the bus so I can run the unit while driving. 799194

Everything worked great. Install was easy replacing a vent on my trailer. One problem was that the knob won’t stay put on the control. Never worked. It barely grips the post and falls off after the unit starts running for only a few minutes. So far it hasn’t dropped into my coffee so that’s good. Unit functions just fine though. I like the start capacitor as it can run on most lower amp services at campgrounds and in my driveway on a regular ext cord. 799051

Review from a similar AC Unit in RV Air Conditioners


I am surprised by the missing inside grill cover. I thought the AC unit would come with a new trim cover for the inside. I used the old one and it doesn’t fit correctly so it’s just hanging there. Does this AC not come with a trim cover for the inside? 765183

Received Advent Air Replacement Rooftop RV Air Conditioner for Carrier Setup 15,000 Btu White- ACCAR150 in excellent condition by UPS. Replaced one of my old Carrier Air V air conditioners on my 32' Damon Daybreak motor home. It was easy to install and the conversion kit that came with it worked very well. Quiet even when running on high speed. Used the same remote and ceiling mount I had with my Carrier Air Conditioner. 528083

Review from a similar AC Unit in RV Air Conditioners


I’ve had the advent ac unit for a year now and love it . Our fifth wheel was preprep for the second ac unit so it was simple to install. We use it mostly to cool the rig down after set up and on those hot humid nights or when the outside temps shot up in the afternoons . But yes I would recommend this unit . In fact if the need would ever arise I’m would order the direct replacement for the factory installed Dometic unit on the rear . Shipping was fast with no damage. 664585

My review is on Lori at etrailer, when I ordered my advent a/c unit I knew it would not be available for 6 to 8 weeks,she kept me informed & when they received a shipment let me know, delivery was quick. Thank you Lori for keeping me informed . Due to travel I won't be installing the unit till spring so I can't review it at this time.

Review from a similar AC Unit in RV Air Conditioners


My husband installed this as a second air conditioner in our 5th wheel. Installation took a little longer than expected due to getting the inside template to line up with the main unit. Also, it is pretty noisy on medium and high; however, that doesn’t bother us as we like to sleep with “white noise”. Overall, it cools well and is a fairly straightforward installation with minor adjustments needed. If you are mechanically inclined, installation should not be an issue. 647387

Review from a similar AC Unit in RV Air Conditioners


This unit can't be beat if you are replacing a stock Coleman--Avery straightforward installation. Airflow is better than my old Coleman but temperature is not. I've taken 3 trips with this Advent on Summer days with temperatures in the 90s, and in all cases the output temperature never got cooler than 60. The old Coleman could blow 50 degrees. 551026


Comments
Where are you measuring the 60°? According to the manufacturer, ASA Electronics, if your trailer has a ducted system, its possible that theres a leak in the ductwork. The best way to rule out the AC unit itself is to measure the output air temperature right as it leaves the unit.

Review from a similar AC Unit in RV Air Conditioners


The unit seems to be a top of the line quality product. Installation was fairly straight forward except the instructions are outdated. Instructions tell you to remove the receiver cover to prep it for mounting the Coleman control panel. The cover is not removable, it's now a high density foam. Also the supplied hardware is not long enough to go through the cover. The photos in the instructions are very hard to determine what they are of. 510096


Comments
Labor Day weekend 2018 we were camping at a site in direct sunlight. While running the unit on high we experienced a smell of something electrical over heating. I feel that the compressor failed. I have been in touch with the company and have the location of the nearest service location but have not been able to take the RV there yet. There is a 2 year warrantee so it shouldnt be a problem just an inconvenience.

SUPER pleased with the product. It was exactly as described and performs exactly as expected. The installation was simple, do-it-yourself, (less than 30 min) using 1 screwdriver and 1 nutdriver. The 15,000 btu unit cools my 41' park model in less than 20 min. Super quiet, and efficient. This unit was used to replace a Dometic Duo Therm and I did not have to modify anything...straight plug and play!

  • Could Solar Panels Power Advent AC Unit on RV
    If the solar panel could provide 15 amps of 12 volt power the Advent Air RV Air Conditioner # ACM135CH could be ran off of it. Since solar panel as a direct power source can fluctuate depending on access to sunlight it's not the wisest to run it straight off of a solar panel and instead having a battery bank get charged from the panel which then provides the power for the AC unit. Or use a generator like # 333-0003. For a panel setup that has the amperage you'd need we have the part...

  • Does The Advent Air Conditioner Have A Thermostat and Can I Power it With My Champion Generator
    Yes, The Advent Air Rv Air Conditioner part # ACM135CH does come with a built-in thermostat that controls the fan setting and temperature of the air conditioner. The Champion generator you referenced features 3400 starting watts and 3100 running watts. The air conditioner uses 1450 starting and running watts so the generator is more than sufficient to power the air conditioner.

  • Can 2,200 Watt Honda Generator Power Avent AC # ACM135CH
    Yes, a Honda 2,200 generator will easily power the Advent Air RV Air Conditioner with Ceiling Vent and Start Capacitor part # ACM135CH. The Generac 3000i would work too. This AC unit draws 1,450 watts so either generator would power this unit with wattage to spare. Since this has a start capacitor you don't have to worry about a surge of wattage requirements on start up.

  • Can Non-Ducted AC Unit be Replaced with Ducted AC in RV
    Your RV would need to have ducts installed in the roof as well as vents elsewhere. There really isn't a great way to install ducted AC unit in a trailer that does not have them. That's why they make ductless AC units like the # ACM135CH which does have a heat pump like you mentioned wanting as well.

    The Advent Air RV Air Conditioner # ACM135CH that you referenced features a fan that will constantly work to circulate air inside your RV but there isn't a dedicated exhaust function to help with pulling air out, especially while you're cooking. This is the case with any of our AC units. For the type of exhaust you're needing a dedicated system would need to be added such as the Ventline Range Hood # S0721-22BD-F-1.

  • Can the Advent Air RV Air Conditioner Be Installed Using Wiring from a Ceiling Fan
    The Advent Air RV Air Conditioner part # ACM135CH is going to pull much more power than a ceiling fan would which means the circuit would most likely 1) not contain the correct gauge wire, 2) have the correct size circuit protection needed and 3) could be DC powered as opposed to the AC powered needed. Therefore, you'd need to run your own wires for the air conditioner unless you were replacing one that is already present.

  • What Type of Generator is Required to Powered AC Unit of Trailer
    The etrailer 2,000-Watt Portable Inverter Generator # 333-0001 could power a smaller 13.5 btu AC unit if it had a start capacitor like the Advent part # ACM135CH but most AC units require more watts than what this can put out upon start up. The start capacitor of this allows it to draw 1,450 watts on start up and when running whereas the Atwood # AT15025-21 draws 3,795 watts on startup and then 1,265 watts once running as it does not have a capacitor. So if you have an AC unit that...

  • Recommended Air Conditioner for 26x7-1/2 Foot Enclosed Racing Trailer
    For your 26x7-1/2 inch enclosed trailer, based on your photo you will want two units. If you simply want to replace the unit, I recommend the Advent Air RV Air Conditioner w/ Ceiling Vent and Start Capacitor - White # ACM135C. This will give you the roof top unit, the vent assembly with built in thermostat, and a start capacitor to make sure you can start the unit even when the shore power is at an amperage that isn't strong enough for most systems to start. The capacitor helps with...

  • Availability of Advent 13,500 Btu Air Conditioner with Air Distribution Box # ACRG15
    There isn't a full Advent Air Kit available that includes the Air Distribution Box # ACRG15 in place of the standard model, however you could piece together your own kit using the individual components. To match the contents of the Advent Air RV Air Conditioner Kit # ACM135CH you were looking at (except for the Air Distribution Box) you would just need part # ACM135 for the 13,500 Btu AC itself, # ACMHD for the Heat Strip, # ACMSCKIT for the Start Capacitor, and # ACRG15 for the upgraded...

  • 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. You can choose based on the BTUs and color you want: - 13,500 Btu - White: Advent Air RV Air Conditioner with Air...

    Yes, if you install the Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners # ACRG15 does control the fan of the Advent AC units like the # ACM135CH that you have. It allows you to control mode, fan, and temperature settings.

  • Does Advent Air AC Unit ACM135CH Require Additional Relay
    You would not need to also purchase the relay part # PXXACRG12RB with the Advent Air RV Air Conditioner w/ Air Distribution Box, Start Capacitor, and Heat Strip # ACM135CH that you referenced. That relay is a replacement part for a different distribution box.

  • 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...

  • Power Draw of 13,500 Btu Advent Air RV Air Conditioner
    The 13,500 Btu Advent Air RV Air Conditioner w/ Air Distribution Box, Start Capacitor, and Heat Strip # ACM135BCH (Black) and # ACM135CH (White) draws 1,450 watts so you will need a generator with that much capacity so keep the AC up and running. For that I recommend the 3,200-Watt Portable RV Inverter Generator - 2,900 Running Watts # 333-0003. I have added links to video reviews for you to check out as well.
