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.

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. 725612

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 796617

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. 729053

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. 573737

Review from a similar AC Assembly in RV Air Conditioners


I wanted you to know that the heater for the rooftop air conditioner is worthless. It only has a 10 degree temperature drop. One of the issues is that the rooftop fan runs on high and you can't slow it down. Unfortunately we have a space heater in the trailer to heat the trailer. 593501


Comments
According to ASA, the manufacturer the # ACMHD is a heat strip, not a heater. A lot of people are confused by this. The heat strip is designed to keep the trailer above freezing and is only 1400W. It is commonly referred to as a chill chaser because that is the purpose - not a heater to provide heat. This is most likely on a non ducted system and does not have a wall thermostat, it is designed to run only when the fan is on. It sounds as though the needs would be better met with an actual heater as opposed to a heat strip.

Ask the Experts about this Advent Air RV Air Conditioners

  • 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...

  • 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...

  • Can a Wall Thermostat Be Added to the Advent Air RV Air Conditioner Kit ACM150C
    I do have other options for you but the Advent Air RV Air Conditioner Kit part # ACM150C is not designed to be used with a wall mounted control nor does it come with one. Instead, we have the Furrion Chill Premium RV Air Conditioner System part # F15PA12SASA-W (15,500 Btu's). The Atwood Air Command Rooftop RV Air Conditioner does only have a 13,500 Btu's rating but we have found this unit to put out the coldest air and to be the most accurate with the Btu rating so this is what I recommend...

  • Installing Advent Air AC Units on 40 Foot Bus
    Two of the Advent Air RV Air Conditioner # ACM150C that you referenced will definitely be enough to cool down your 40 foot school bus. I did reach out to my contact at Advent Air just to get his opinion on this particular application along with obtaining the power draw of the unit to see what type of generator is needed. He said before proceeding there are a couple things you will want to be aware of. This AC unit (along with all of the Advent Air models) are designed specifically...

  • 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.

  • What Size Generator To Run Advent Air RV Air Conditioner 15,000 Btu With Start Capacitor
    I contacted Advent and the Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor part # ACM150C needs at least a 3,000 starting watt generator to start the air conditioner even with the start capacitor present. I recommend to use etrailer 3,200-Watt Portable Inverter Generator - 2,900 Running Watts part # 333-0003 which will give you enough starting watts to start the air conditioner and extra to run a small appliance if you needed to. It also has a remote start so it's...

  • Recommended AC Unit for 22x8x7 Foot Race Trailer
    Since you don't currently have and AC unit, I recommend the Advent Air Rooftop RV Air Conditioner w/ Ceiling Vent and Start Capacitor - 15,000 Btu - White # ACM150C. This will give you the ability to cool your race trailer faster and won't have the big power draw at start due the integrated capacitor. The Advent Air Command Rooftop RV Air Conditioner - 13,500 Btu - Non-Ducted - White # ACM135CH will also work well for you.

  • 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.

  • Ductless Air Conditioner for 40 Foot Race Trailer
    That's a good question and realistically, one of the 15,000 or 15,500 BTU air conditioners may be enough to meet your needs, it just depends on different factors, such as how much time you are spending in the trailer, the temperature outside and if any part of the trailer is going to be open for any period of time (I know some of these trailers have side doors as well). Since you can always add on, what I recommend is just starting with one unit, the Furrion Chill RV Air Conditioner...

  • 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...

  • Can an Air Conditioner be Installed by a Do-it-yourselfer in an Enclosed Trailer Prepped for AC
    Since the trailer you are getting has the opening, brace, and wiring ready to go all the hard stuff will have already been done! I don't think you will have any problem installing AC unit # ACM150C yourself. It pretty much just bolts on. Two people are recommended for installation; one inside and one outside, to make sure it is lined up properly, but other than that there isn't anything special that needs to be done.
