This electric heat strip works with your AC unit (sold separately) to remove the chill from your RV or camper on cold or frosty mornings. Power cord and mounting hardware are included for easy, plug-and-play installation.
Features:
Specs:
Paired with your AC unit (sold separately), this electric heat strip takes the chill out of your RV on cool, frosty mornings. It is operated with the control dial on the air distribution box (sold separately). After you turn the dial to the 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.
To install, mount the heat strip 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.

Ya deje una reseña anterior mente de este producto, y estoy escribiendo algo más por que final mente logre que funcionará después de una semana de fallidos intentos, en las instrucciones de este producto dice que debemos rsetear el termostato a los ajustes de favrica después de poner los botones en l parte posterior en el lugar deseado, pero esa forma no funciona en lo absoluto, la manera con la que pude lograr que funcionará es desconectando el cable de 12v positivo del termostato y así es como logre que funcionará eso no lo explican en las instrucciones creo que es algo que deberían agregar para algunas personas que no logran hacer una correcta instalación después de muchos intentos de restablecer el termostato como indica en el papel, seguía estando en el modo furnance, nunca cambiaba para ht strip que era el lugar donde quería que estubiers, al final logre que funcionará pero fue como esplique anteriormente, desconectando el cable de alimentación del termostato
They don’t really heat

Hi Carlos, The Advent Heat Strip # ACMHD is really only meant to knock the chill out of the air and shouldn't be relied on as an only source of heat when the temp outside gets cold.
While they work with Advent air conditioners they don't work with my Coleman Mach thermostat system. This bit of information was left out of the description so I had to return them.
Heat strip works great. Adds just enough heat to our RV so we don’t have to use propane on cool mornings. Etrailer has been great to work with!
Heater mounts easily and install takes 5 mins. Plugs right into control box.
The heat strip is easy to install, it is great if you only need it to break the chill, it does not get super warm, but it works for my general needs.
A/C was delivered as promised, fit perfectly and operating better than the old Domestic that was replaced 3 years ago. Hopefully it will last as long as the 10 year old rear unit has lasted. I plan to replace it next summer with another one of these Avent units.
The first time I plugged it up it didn’t turn on. I jiggled the cable and it started heating. I then installed it and turned it on again it doesn’t seem to work so I jiggled the wires and it seems to be working but it’s not very hot at all. Luke warm air at best. I’m somewhat disappointed with the outcome. I read reviews before I purchased this. Some said it worked well, and others said it didn’t heat well. I’m going with the latter. Does not heat well enough.
Seems to be a pretty well made part. Blows warm air. But as far as shipping they are very slow. Warehouse is slow about putting your part out in a timely manner. Ordered on Friday morning got put out to ship Monday evening.
Unit went out in less than one year. Things happen. ASA electronics sent out a new unit quickly but refuses to pay for the install on their faulty unit.
I received the heater unit & promptly installed it. Being a competent mechanical type, I found the installation to be straightforward but a bit painful. On the left side (w/elect terminals) was a slot in the protective metal screening for the purpose of using a screwdriver to install the 2 short screws. Difficulty came when trying to weave the screwdriver through terminal ends and wires while trying to guide the screw into the bracket slots.
On the opposite end, there were no electrical terminals, but neither was there a slot in the screening. This required a small diameter Phillips screwdriver to get through the metal screening. In my case it took way longer than one would anticipate to install 4 small screws. It was all good in the end & I am pleased with the product, how it is integrated into the a/c unit and how it functions.
It may be worth mentioning in the video & written instruction, that the HEAT position on the air distribution box also provides power to the fan for heat circulation. I did not see or hear that mentioned anywhere and caused me to question it. By trial, I discovered it's functionality.

Can this be installed as a standalone unit?

Advent ac unit works extremely well. I have two that are installed in vintage camping trailers as replacements for the 1970s OEM units. They installed easily & function flawlessly. I would not hesitate to buy yet another if the occassion arises.
Was hoping this would produce at least a bit of heat. Installed and then tested it while temp outside was 30F. First it drew more than 15amps, had to start the generator in order to produce enough amps to keep it running. After 20 minutes no real heat, so kinda sad. However customer service here is great.
Wish it was better, but hay not always what you expect, but I tried.

Still working fine, not as much heat as I was hoping however it helps in not having to use propane as much.
Added as a second unit to a 33' Crossroads. Works great. Easy straight forward install. Using the ACRG 15 air distribution box with thermostat. All the wires are labeled from the factory so installation was a snap. Added the ACMHD heat strip also but it's 85 degrees and a little hard to test that out just yet. The crew at etrailer were great at helping me get everything picked out that I needed. Shipping was fast. If there was such a thing as a 10 star rating, they deserve it
I installed the heat strip in my Advent air conditioner and it worked great, instructions were very good and it worked well, nice and warm. We had just installed the ac unit in a pop up camper and it was great, does not drip water on roof. Very happy. Steve
I purchased this heat strip for the Advent AC135 rv rooftop air conditioner. The ACHD is the heat strip that is recommended for my unit but has been discontinued. The electrical specs for the ACHD and the ACMHD are the same, as is the width and height. I was able to match the curbside holes on the evaporator with the heat strip flange precisely. I mounted the heat strip and used the roadside heat-strip flange as a guide to drill two holes for a solid mount. Pretty simple after I clipped away a small portion of the cage that surrounds the heat strip. Plugged it in and, voila, heat. Works great. Sorry, no pics. And I don’t want to remove the shroud again if I don’t have to, as putting that back on was the hardest part of the job.
I installed two of these strips. Installation is incredibly simple. You can get this done in 30 minutes or less with just a screwdriver. The one I installed above the main cabin keeps the RV comfortable. My bedroom area is signicantly smaller and the unit that services it keeps it quite warm. I usually have to cycle the fan and heat option to keep the temperature where I like. The Advent heat strip is a good option. For reference, I am living full time in my RV.
Works great... Keeps the house nice and warm. We used it all winter and it was perfect.
Unit arrived, albeit late. Fortunately it’s not a big deal because I don’t need this particular part of my order for a few more months (it’s still the peak of summer for me).
Works well. easy to install. Only knocks the chill off. You will still need an alternate heat source if you are in cold weather.
Toasty heat strips
I just installed the heat strip and it was simple. My original thought was to purchase this from a well known department store who cancelled the order. I then tried Amaz.... but their price was crazy. A call to the manufacturer directed me to etrailer! Pricing was very competitive in fact budget shipping beat everyone so I placed the order! I couldn’t believe how quick I received it. etrailer is on my speed dial now!
worked great for us!
I received the order a week early. Only issue is that the frame was damaged in shipment but was isolated to the frame and no other damage. Installation was straight forward. Installed on 7x14 trailer. Hardest part was removing vent opening sealant from the roof. Ran fine on initial start-up. Will test with heat load today.
Seems like a great product so far. Installation was simple and it cools a 8.5x28’ trailer easy.
One note: you must have 120v and 12v supply for this AC to work. I did not know that and had to go through some extra trouble of running 12 V power source.
The heat strip works well. I would like more temperature control. But it certainly warms the living quarters of my trailer.

José, eso suena frustrante. Lamento que estés lidiando con esto. El termostato no controlará la temperatura de la tira térmica. ¿Has probado a poner el termostato en modo aire acondicionado y subir la temperatura? La tira térmica funcionaría en modo aire acondicionado o modo ventilador. Déjame saber si ya lo has probado y contáctame.
