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.

How It Works
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.
Simple Installation
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.

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!

Easy to install, works as advertised. Only issue was reprogramming thermostat. After installation the thermostat did not respond to the factory reset. Simply pulled the fuse for a few seconds, then all was good.

Defective! Silly that this is sold separately. Mounted it in the unit, tested it and it was faulty. Had to return.

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

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.

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.

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.

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.

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

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 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.

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.

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.

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.

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!

The heat strip works well. I would like more temperature control. But it certainly warms the living quarters of my trailer.

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.

Works well. easy to install. Only knocks the chill off. You will still need an alternate heat source if you are in cold weather.

I've been dealing with etrailer for quite a bit of supplies lately as I'm building a cargo trailer/camper conversion. This item, along with everything else I've purchased has been great quality. No complaints here!

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.

- Air Conditioner Replacement For Dometic 59136.331 That Ran Out Of FreonThe Dometic air conditioner units are sealed therefore they cannot be recharged with refrigerant. The only option is to replace the unit. Since your unit is a 15,000 BTU unit I recommend to replace the AC with a unit at least 15,000 BTU. I recommend Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor part # ACDOM150 which is a 15,000 BTU system that will easily plug into your existing Dometic setup without replacing wiring. As long as your air distribution box...

This is a 15,000 Btu replacement option that plugs directly into your current Dometic setup and works seamlessly with your existing, in-good-working-order Dometic air distribution box and thermostat. The benefit of his option is that has an adapter wiring kit, which saves you time and effort. This does not have a heat option, but you can choose to add the...

If you're just wanting to replace the rooftop unit and maintain use of your air distribution box and thermostat controller then you can choose between the Furrion Chill HE Replacement RV Air Conditioner Unit # FR58PR (along with an adapter # ACCARKIT) or the Advent Air Replacement RV Air Conditioner for Carrier Setup # ACCAR150. Of the two I personally prefer...
view full answer... - Best Option For Replacing Carrier Air V Air Conditioner With Heat PumpHey Jason, our best option for replacing the Carrier Air V air conditioner is the Advent Air # ACCAR150 which is a 15,000 BTU air conditioner. This unit comes with a conversion kit which makes it directly compatible with the existing ducted Carrier setup. Meaning you will not have to change out any of the vents or thermostat inside the camper, only the rooftop portion. If you would like to replace the distribution box you can use part # ACRG15 for a new vent and thermostat. The heat strip...

The air will dump from the air distribution box from the slotted registers in the front and back of the box. This air conditioner system works with ducted or ductless systems. Furrion is working on a heat strip for their units, but it is not avalable at this time. The Dometic penguin heat strip will not work with the Furrion unit. If you need the heating...

To match the contents of the Advent Air RV Air Conditioner Kit # ACM135CH you were looking at (except for the Air Distribution Box) you would just need part # ACM135 for the 13,500 Btu AC itself, # ACMHD for the Heat Strip, # ACMSCKIT for the Start Capacitor, and # ACRG15 for the upgraded...

If you want to add a start capacitor # ACMSCKIT or heat strip # ACMHD they are available separately.

However, we do have available the two Advent AC models that are designed as replacement units for the Carrier Air V. I recommend using the Advent Air Replacement RV Air Conditioner for Carrier Setup, # ACCAR150 for 13,500 Btu's or # ACCAR135 for 15,000 Btu's. These options do not have a heat pump integrated into them. If however you decide later that you prefer, you can...

- Recommended Replacement for Carrier 68RV14102A Air ConditionerHey Tom, thanks for reaching out! I recommend checking out the Advent Air Low Profile RV Air Conditioner # ASA38YR which comes with a connector to plug in directly to your Carrier wiring. This doesn't work with an existing heat pump, but you can add the Heat Strip # ACMHD to make the air warmer in the winter.
view full answer... - Why Doesn't Advent AC Heat Strip Raise Temperature High in the RVHey John, 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. To heat up your living space to whatever temp you're wanting, you'll either need a furnace or a fireplace like the Greystone # 324-000076 in order to do that.

All of the old air distribution boxes and thermostats were designed for R410A so a complete system replacement is required.

So far so good. We have not had the chance to try out the heater this year but plan on a trip next week. Hoping it will work well.
