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

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.

Has no thermostat to set temperature. You can only turn on and off. Runs and blows constantly. Not happy with that.


Comments
Thank you for your review. The air distribution box does include a thermostat that ranges from 65 F to 90 F 16 C to 30 C. The thermostat may not be working properly if your AC runs constantly, this unit does have a 2 year warranty.

Review from a similar Advent Air AC Assembly in RV Air Conditioners


Hello .. My first unit came damaged ref # 111032829. I contacted Matt who helped me out. However the replacement unit took several weeks to arrive part was back ordered . I am sure the unit was damaged before it was put into the box as the outside of the box showed no damage . Ps the main frame was bent and a portion of the copper tube on the evaporator as damaged, unit is not repairable . Anyway the new unit was delivered yesterday and it came with FRAGLE STICKERS on the box good idea . I am very please with getting the replacement unit .. I have to say the people I talked with at etrailer we very helpful and I will purchase from them again ...

Review from a similar Advent Air AC Assembly in RV Air Conditioners


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.


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.

Review from a similar Advent Air AC Assembly 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.

Review from a similar Advent Air AC Assembly in RV Air Conditioners


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!

Review from a similar Advent Air AC Assembly in RV Air Conditioners


This was purchase for a front 5th wheel living room. Discharge vents face the front and back of the trailer, it would be better if they were on the sides facing the couches. Unit is very loud even on low to be used while watching television. The included 7” mounting bolts are too short for a 5” thick roof plus the roof gasket. Needed to go up on roof and use my 220 lb frame to sit on top of the unit and compress some of the roof gasket with my wife inside to get 3 of the 4 mounting bolts started. Will need to go to a home improvement store tomorrow to buy a longer mounting bolt to complete the installation. The plastic prongs on the hole plug crumbled during installation and fell out. Not impressed so far, will need to wait for a warm day to see how it performs.

Review from a similar Advent Air AC Assembly in RV Air Conditioners


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.

Review from a similar Advent Air 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.


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.

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...

  • 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...
