  • Stay on the road during the off-season or in cooler locations where you'll need a heater to take off the chill
  • Have an RV with an air ducted system

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.

Customer service was great! There was a slight delay in shipping all the parts (due to an internal issue), but I was kept informed & everything arrived as ordered. I would recommend this company & this product.




by:

Unit was out of stock when I ordered but they beat the original delivery date by 4 days. It was in good shape and works great. Company always does it’s best and that’s not always the case.




by:

I really like these units, they seem to weigh less the the competition and are very affordable. I also like the three fan speeds instead of two from the competition.




by:

Just got ac going to put in next week. Everything looks ok




by:

The air conditioner that we ordered arrived in excellent shape and a week early. I have ordered 6 things from etrialer all have arrived ahead of time and in excellent condition.




by:

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

I installed it on a Tuesday And what camping on Saturday the temperature was 105° outside Add the air conditioner and keep my camper 70° all day inside. I will highly Recommend this product. My camper is 117' fiberglass Casita.
I had to use the old Gasket with the new gasket that the new air conditioner came with Because my camper roof was to thin.

We are very pleased with the purchase of the 13,500 BTU Advent Air RV Air Conditioner for our camper trailer. Excellent customer service from the moment we placed the order.
Especially helpful was the video tutorial step by step how to install the AC.
It works perfectly and will almost freeze us out of the trailer on High!!!

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 ...

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.

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


Put it in my bedroom, really helps on those 90 degree plus days. Only thing I don’t like is when it’s on the fan runs all the time. May replace my aging main dometic unit in the near future


Comments
This is the 3rd summer of using this AC and its working well. Optional heater I installed helps take the chill out of the air in the spring and fall.

This little A/C works great! The only sound is the sound of the air flowing out, no mechanical noise. I have not installed the optional heating unit but plan on doing that 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.

  • Recommended Replacement For A 15,000BTU Atwood RV Air Conditioner System

    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).
