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.

Video Transcript for Advent Air RV Air Conditioner with Air Distribution Box Start Capacitor and Heat Strip Review

Today we'll be taking a look at the Advent rooftop air conditioning system, and this is what our unit's going to look like when it's fully installed. You'll have your controls just at your fingertips. It's going to be a full climate control system that's going to provide heat and air conditioning. This rooftop AC unit will mount on any RV, enclosed trailer, or anything else that you can cut a 14 and a quarter by a 14 and a quarter inch hole in. You do want to make sure you've got room on top of your trailer, as well, that it won't contact anything. It's going to measure 24 and seven eighths inch wide, 31 and three sixteenths inch long, and 12 and 13 sixteenths inch tall.

As long as you've got clearances and can cut the appropriate hole, it'll work on your unit.If you have a smaller unit, one will be sufficient, or if you have a larger unit you can use multiple to adequately cool or heat your unit. There's a collapsible gasket underneath that'll tightly seal to your roof to prevent any moisture intrusion and any air leaks. The cover can be removed by loosening the screws on the side. This way the unit can be serviced for the life of your trailer or RV. One of the features that sets this apart from other units is its hard start capacitor.

This is going to allow it to store a charge so it can start on lower electricity loads such as a generator.Here we've got our generator, we can plug it in, and it'll start up just fine. If you're at a campsite that doesn't have its own 20 amp power circuit, you can plug into your generator and unlike other AC units, this one will start up just fine every time, whereas other AC units may struggle to start because the generator doesn't have enough output to kick it over.This high output rooftop heating and cooling system has three fan settings, options for heat and cool, an adjustable temperature knob, and uses the condensation dispersing system to prevent water runoff. It has an adjustable vent to change the direction of airflow. There's also one located in the front. This comes with both a tilt and direction adjustment.

There's a removable air filter. It can be cleaned and then reinserted to make sure your unit stays operating optimally throughout the year. The inter vent unit is about 22 and a half inches long, 21 and a half inches wide, and three and a half inches deep, to the edge of your knobs.Here we have Hayden with us. He has a lot of experience with RVs. So what do you think about this unit compared to other units Hayden: Well, right away what I like about it is like, I know you already mentioned the starting capacitor, but that really is the coolest thing about this.

You're not going to have to worry about any circuit overload with this one. That is pretty neat. I was looking at some of our other units, such as the Atwood, and that one doesn't have that. So is there anything else that kind of sets this one apart in your eyes Hayden: Well, the other nice thing about it is you don't have to worry about picking up any additional parts such as a clock or a sealant because this one comes with it. So it's a worry free installation. So you don't need to worry about picking up anything, because you install it and it's sealed right up. That was nice. He had inaudible 00:03:08 it right down and we we're good to go. Hayden: Absolutely. We've gone over some of our operating features. How do you like these compared to other units Hayden: Well, I mean, it's pretty basic. It's a standard two knob control system here. You know, though, it doesn't have a remote. The nice thing is you don't have to worry about losing the remote, but as far as the knobs, they're rubber coated. They're easy to grip. I mean, it seems like they're going to hold up for a long time. Yeah, it's pretty, it's a nice simple solution that works just fine. I noticed that compared to our Atwood, the Atwood has a sleep timer, which could be more convenient. Hayden: Sure. But yeah, overall, it works as it should. And that completes our look at the Advent rooftop air conditioning system on our trailer.

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

Great response time . Haven't installed yet but it appears to be in perfect condition. 642380

- ACM135CH

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

The order came in super quick. I can't report on performance of the roof top ac or fan yet, as my rv isn't ready for them yet. It they work half as good as delivery, I know they will be great. 574262

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

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. I have bought from etrailer in the past & will again in the future, Great job. 572881

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

- ACCOL135

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

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.

Review from a similar AC Unit in RV Air Conditioners

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

- ACCOL150

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

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

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! Many thanks to the team at etrailer for the great service and lightning fast shipping! I will definitely be a loyal future customer. 540255

Review from a similar AC Unit in RV Air Conditioners

This is a direct replacement for a unit that I have. A tree branch put a hole in the condenser. This was not the fault of the unit. I was able to remove the six Phillips head screws on the inside shroud, unplug two cables and remove four 10mm bolts, then remove the old unit. once the old unit was out of the way place the new unit in place and reverse the process. I think the whole process took me 30 minutes to complete. It works just as well as any other unit I have owned. 518681

Review from a similar AC Unit in RV Air Conditioners

Amazing product, I will definitely recommend Advent to all my RV friends. Extremely easy to install, just a little to heavy to get up a ladder alone so i used a tractor to lift the unit to the roof of my RV, 4 bolts on the inside to remove and the wiring harness and off with the pos demetic, placed the Advent right in place bolted it down turned it on and instantly got cold air, very cold air! Only thing you have to install which I think the factory could do but, was easy. 516122

  • AC Unit Recommendation for Enclosed Race Trailer
    I prefer the Atwood AC units over the Advent Air ones as they tend to blow colder air. For a single unit I'd go with the 15k BTU Atwood part # AT15025-21 which is for non-ducted applications like your enclosed trailer. This also has a heat pump too so if you were ever cold you could warm up.

  • Will 13,500 Btu Advent Air Rooftop RV Air Conditioner be Sufficient for 98 Square Foot Trailer
    For your travel trailer that is only 98 square feet, the Advent Air Rooftop RV Air Conditioner w/ Vent # ACM135CH that you referenced should have plenty of capacity with its 13,500 Btu per hour cooling capacity. Generally speaking this Btu per hour capacity is sufficient for a space that is up to around 550 square feet, so this should do a really nice job for your application. The air conditioner itself measures 24-7/8 inches long, 31-3/16 inches wide, and 12-13/16 inches tall. This...

  • 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.

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.

  • 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 Advent Roof Air Conditioner have Remote or Wall Thermostat Option
    The Advent AC unit part # ACM135CH that you referenced has a thermostat built into the air distribution box which will be on the ceiling of your RV but does not have a wall thermostat option. It does not have a remote either. For a similar 13,500 btu AC unit that does have a remote we have the Atwood Air Command part # AT15025-21 which also fits non-ducted applications like yours as well.

  • Can Advent Air RV Air Conditioner Be Ran in Fan Mode Only
    The Advent Air RV Air Conditioner you referneced, part # ACM135CH can be ran in FAN mode only. You'd adjust the thermostat to the warmer settings then set the fan to the desired level. This will operate the fan without the A/C compressor. This is mentioned on page 12 of the owner's manual which I've linked for you to look over.

    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...

  • 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...

  • Does Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners Control Fan
    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.

  • Can Air Distribution Box ACRG15 Be Used with Advent Air Conditioner # ACM135CH
    Yes, the Air Distribution Box # ACRG15 can be used with the Advent Air RV Air Conditioner # ACM135CH to provide an upgraded box with digital temperature control and a wall-mounted thermostat like you mentioned. It is perfectly compatible with non-ducted units like this. I have attached a short video review that you can check out as well.

  • Atwood AC Unit Recommendation that Has Heat Pump
    The # AT15025-21 non-ducted system does not have a heat pump setup, but the # AT15028-22 which is larger at 15K btu and is ducted does have a heat pump if you are in need of that function. If you want the 13k non-ducted fit and function, then I recommend you go with the Advent Air RV Air Conditioner w/ Air Distribution Box, Start Capacitor, and Heat Strip - 13,500 Btu # ACM135CH instead.

  • Air Conditioner Recommendation With Heat Strip and Start Capacitor For Use With Honda Handi 3000
    The Atwood Air Command Rooftop RV Air Conditioner part # AT15025-21 comes with a rubber gasket to seal the air conditioner on top of the trailer. I do have an option for you but the Atwood non-ducted air conditioners currently do not come equipped with a heat strip, heat pump or start capacitor. The advent brand heat strip and capacitor is not compatible with the Atwood brand and without a start capacitor the Honda Handi 3000 generator will not be capable of starting the air conditioner. I...

  • Proper SIze Air Conditioner for 28 Foot x 8-1/2 Foot Enclosed Car Hauler
    For a 28 foot x 8-1/2 foot enclosed car hauler a 13,500 Btu AC unit like the Advent Air RV Air Conditioner # ACM135 that you were looking at will work great. This will do a really nice job of cooling this size space with a capability to cool 500 cubic feet per minute. You might be able to get away with something a bit smaller but going with an AC unit that has a bit more capacity than needed allows it to work less and more efficiently when it does, leading to a longer lifespan and less...

  • 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 # 333-0002-2-0007. I have added links to video reviews for you to check out as well.

  • Do I Need a Plenum Box In RV To Use Furrion Chill Air Conditioner
    The Furrion Chill Premium RV Air Conditioner System part # F15PA12SASA-W will work without a plenum box because it comes with an air distribution box. The air will dump from the air distribution box from the slotted registers in the front and back of the box. This air conditioner system works with ducted or ductless systems. Furrion is working on a heat strip for their units but it is not avalable at this time. The Dometic penguin heat strip will not work with the Furrion unit. If you...

  • 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...

  • What is the Difference Between Ducted AC and Non-Ducted?
    An air conditioner that is non-ducted such as the Advent Air RV Air Conditioner # ACM135CH has the air coming directly out of the AC unit itself. A ducted unit such as the Atwood Air Command # AT15033-22 would be installed if your motor home has air ducts in the ceiling that the unit distributes air to. The closest unit we have to what you are asking for is the one I just mentioned, the Atwood Air Command # AT15033-22. This is a ducted unit that is black, has a 15,000 Btu per hour cooling...
