Specs:
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.
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.
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.
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.
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.
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.
2-Year limited warranty covers defective units when installed correctly on approved applications. The warranty does not cover units installed incorrectly. To ensure air conditioner is installed correctly, please see the questionnaire pdf below. A filled-out questionnaire is required for warranty coverage.
If you are not comfortable using a voltmeter (or removing the charge from the start capacitor), youll want to make a service appointment with your local RV dealer to verify the installation. Print the pdfs below (warranty- questionnaire, warranty dealer information) and take them along with the RV to your local dealer. ASA does compensate dealers for warranty work as outlined in the dealer information pdf. You may be charged by the dealer for time spent investigating the installation.

2nd year was great, 3rd year it wont even turn on it just hums like the motor or compressor is locked up. This sucks for a backup ac. my ,main original AC from 2005 is still working fine but this add on mainly for a backup to help the main only lasted two years. not good :-
Great product! Quick shipping, and great service. This is where I will buy all my RV and CamperVan supplies.
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 ...
This is a very poorly built air conditioner. My son told us not to even install it when he seen the hard start in it. But we thought it would be fine. WRONG. Didn't even get 1 camping trip in. Now they refuse to take it back and the manufacturer wants us to pay to get it checked out. The compressor is out. Cheap crap is what we got.
Shipped undamaged easy to install it cools the RV great would buy again
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.

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.
Does not even put out enough cool air to cool a sprinter in 78 degrees . Will replace with something else .
AC is great 10/10
The heat strip is useless. Unless you like slightly colder than lukewarm air, then it's probably fine.
Well, it just doesn't move much air. I own several other rooftop A/C unites in my trailers. All of them move more air than this one. I do like that is draws very low amperage which save generator life an fuel, but it simply does not cool as well as others I own. Aside from that issue, install was very simple, arrive on time, and is easy to operate.
Great air conditioner. There was a back order on it, but when I received it went in easily. Everyone at etrailer was great to me. I will always go back.
Etrailer isfantastic!! I would definitely purchase from them again.
We haven't installed the products yet. Due to weather, it may have to wait until Spring. So I can't give the product a review.
But, I will be checking Etrailer first, for any items that I may need for my RV, in the future.
Thank you Etrailer

Still going strong. One year in and no issues. Usually I use it as primary during the day since the fan runs continuously then turn it off at night and then my main ac run during the night as it will shut off during cycles. But lately with it hitting 110 on a regular basis Ive been running it 247 and letting the main cycle to take up the slack, my main ducted unit is 18 years old.
