Brisk 15K BTU

I have a 2017 Forest River Vibe with a rooftop a/c unit that had gone out. After much research I found this one on Amazon had the best price and fastest shipping, so I ordered it. The unit arrived within 4 days, fortunately, and without any damage. The unit comes ready to install, with the seal already attached to the base of the unit, so all you need to do is remove the 4 bolts holding in the old unit, unplug the wire connector from the interior ceiling air return or control unit, install the freeze sensor (see below) put the new unit in place, plug it in, bolt it down, and turn it on. It's all very simple. Unfortunately there are no installation instructions provided with the unit, so before uninstalling the old unit, I recommend using a sharpie or nail polish to mark the bolt threads where they enter the a/c unit so you'll know just how far to screw them in when installing the new unit. You may want to clean the roof prior to installing the new unit, to make sure you don't get any dirt, leaves, or other debris trapped between the roof and the seal, as this could lead to leaks. Also, be sure to rotate the fan on the new unit and make sure no packing material is lodged in it. We had a small piece of foam in ours which made it vibrate when running. We then removed the foam piece to find that it still vibrated, though not nearly as much. This was due to the fan being slightly misshapen and unbalanced, but after running for a few days the wobble is completely gone. As for noise level, the new unit just as quiet/noisy as the old unit, but it cools way better. Before our old unit quit working, we'd have to put the thermostat at 72 or lower to notice any cooling whatsoever. However, with the new unit, we keep it between 75 and 78 depending on the time of day, and that keeps the RV plenty chilly, almost to the point of needing to wear a light jacket. The new unit seems to be slightly smaller than the old one, and also seems to weighs less, but looks identical. Also, when we started up the new unit, our Dometic thermostat showed and E5 error code. After looking this up on the web, I found that it was an "Open circuit or out of range freeze sensor". Come to find out there was a white wire which we unplugged when removing the old unit. After investigating, the wire is actually a freeze sensor with one end which plugs into the control unit (the part on the ceiling), and the other end is a sensor which was simply pushed in between the fins on the evaporator coil. I recommend watching a video called "How to property install a coil sensor" on YouTube before you install this. Also, it's easier to install this before you bolt down the new unit. One difference between our old unit and this new one is that on this unit, the fan seems to run all the time, literally non-stop, and only the compressor starts and stops as needed to maintain the temperature. On our old unit, the entire unit would shut down when needed. One reason could be that I think this new unit is designed to be used with the control panel on the ceiling, and not with a thermostat, so that would explain why. As for getting these units on and off the roof of your RV, I used some tie-down straps which I ordered here on Amazon a while back. I simply weaved the strap in and out of the holes in the base of the a/c unit, and hauled it up while my son guided it up the ladder (also from Amazon) from below. This was a very fast, safe, and easy way to transfer these units, just make sure you've got good footing before doing so. Due to the ease of installation, as well as the item price, and fast shipping, I give this item 5 stars. If you found this review helpful, please leave a helpful vote. Thank you :)

This 15k btu air conditioner is perfect. We needed to replace both air conditioner on top of our RV (low branch incident...need I say more), and I decided to stick with what I already had brand wise. I have experience doing a lot of maintenance type work with my job, but was not sure how this would go as I had never worked on an RV system. This turned out to be super easy, so easy in fact, that I believe anyone can do it. The hardest part was getting it on top of the RV. After that it was simple. This item does not come with instructions, so I looked at a few blogs and articles as well as some YouTube videos before starting. Here is the basic breakdown of what you need to know if you are going to do the same thing. First off, the only tools needed are a Philips head screw driver and a 3/8" socket or wrench. You may need a flat head screw driver as well, but having done two in a day, I didn't. Secondly, the only thing this comes with is the roof top unit and the gasket. That's it. So if this is a new install, you will need the electrical connection kit and the ceiling kit of your choice. Back to what I had to do. First thing is to remove the filter/ceiling unit cover using a screwdriver. Once the cover is off, you will see the ceiling template (metal bracket that holds the whole thing in place) as well as the electrical connection box. Make sure the power is off before moving on...got it, ok. Ok the outside of the box is a white plug with six wires...simply squeeze the sides and pull off...its that easy. Now, you should see two black wires going up into the a/c on the return side (filtered side), reach up and carefully pull out the freeze control sensor off of the evaporator coils (looks like a radiator). Make note of where it was placed as you will place it in the same spot on the new one. The next step requires the 3/8" socket/ratchet. There are four bolts that hold the unit in place along the outer edges of this metal frame. Loosen them all up and remove them. At this point the metal frame will want to hang on all the wires. I just let it hang personally, lowering it slow enough so as not to damage anything. At this point you can go up too and remove the a/c unit. It might stick to the roof as it's probably been there a while, but it's no longer connected. Be careful, the a/c unit is 80-85 pounds which while not outrageously heavy, due to its shape and size is awkward and can cause a back injury. So now I'll skip ahead and assume you've moved the old unit out of the way and have the new one on the roof. Before moving the new unit completely into position I would first make sure to clean the area the old unit was in. Also do not drag it around and slide it too much as you could damage the gasket. Try to move it as close as you can to the right position, with the gasket being an not a 1" thick I was able to look underneath and get pretty close just by seeing the line of the old a/c gasket on the roof. Once your satisfied, go back down below. Looking up into the hole you want to see that the unit is centered pretty well. From down here you can actually reach up and push/slide it around a little to get it just right, making sure that the gasket will seal all around. Once you're satisfied with its placement, now comes the easy part. Grab those 4 long bolts and your 3/8" socket again and put the ceiling template back in place. Tighten them in a cross pattern a little at a time, the manual (I found it online) says to tighten to 40-50 inch pounds (not ft pounds). This means 3-4 ft lbs which you probably don't have a torque wrench that will work at that low a value. Let's just say it's not super tight. You can crush your roof as well as bind the unit if you over tighten. I will say that the 1" gasket will compress down to between 1/2-3/4" when tightened properly (if you do get any leaks you can tighten a little more, but if you over tighten you won't be able to and you will have big issues). Moving on. Once the a/c is as tight as it needs to be, place the freeze control sensor on to the new unit's coils, reach inside the new unit and pull out the power plug and plug it into the electrical box. At this point I would turn power back on to test the unit. If you turn it on and everything sounds right you're good to go, simply reattach the ceiling unit/filter housing and relax. Congratulate yourself on a job well done!

I used to design and maintain equipment in industry. When my Carrier Air V died, I needed to to replace things quickly in the HOT Texas summer. The unit arrived a couple days late due to carrier issue, no biggee, just hot. Went up on the roof without too much issue considering we used a forklift to get it there. Fairly light, easily managed. Comes with seal already, lined up perfectly. Moved to the inside and NOTE: The controller with blots is EXTRA! So I wait a few more days. More cryptic documentation comes with the controller. Finally got a reply from the website help telling me I needed a controller, after I put it in. Figured it out, quite easily after looking at the "molex" connector. Powered on OK, but noisy! Sounded horrid!. Went back up top, opened cover and found both fans had been rubbing. Re-centered them and it works like a dream now. Very satisfied. The entire job totaled out at 1075$, including the incidental wire etc. Bottom line, you can save a thousand dollars by DYI, just know there will be some bumps along the way. OR; If you don't have a basic knowledge of doing things yourself, well consider shelling out the money for an installer or be ready for a steep learning curve. 1 to 10 on the hardness scale, about a 3 (fairly easy). 1 to 10 on the frustration scale about a 5 (moderate). 1 to 10 on performance 10 (excellent). Would I do it again if I had to, absolutely!

We are so impressed by the difference between the stock Dometic 13,500BTU and this cooling phenomenon. Hard to believe the difference that 1,500BTU's makes with newer electronics and more power. Our Class C motorhome with the earlier model simply could not keep up with the summer heat in the South, but this new 15,000 BTU AC has to be tamed to keep us from freezing...regardless of the outside temperature! Easy installation by pros and a direct replacement for the earlier model while still using the original thermostat and heat pump. Simple, easy, and oh so effective cooling! The only issue we had was a cracked shroud from shipping, but Amazon Customer Service took care of us without any problems...so A+ to their customer care. All in all, this is a GREAT advance and improvement over the stock 13,500BTU unit, and very honestly deserves the FIVE STAR rating that we are giving it. Reasonable cost and easy installation are two of the reasons that we can honestly and very heartily recommend this as a replacement or new installation! Happy travels...especially in Summer! *If you found my review helpful to you, please let Amazon know by clicking the "HELPFUL" button below!

Great plug and play swap out. New unit came in good shape so cudos for shipping (FedEx). The folks I purchased from were responsive as well. Great experience all around. Ps I tied it off (still in box), with rope, and was able to pull it onto the RV roof. I'm 70 years old....

July 29, 2023 - Update It's been almost a year now. Even though this Brisk II is touted as a 15K BTU AC, it cools like the original 13K Dometic . . . not enough. Most RV AC systems cool your rig about 20 degrees from the ambient air temperature. When it is 100 degrees and above, that is not much. My Dometic Brisk II cools about 15° below the ambient air temperature. I wish my 15K Coleman hadn't broken during the roof repair. October 12, 2022 Research shows that the thermostat that you must buy separately to work with this has a common problem of temperature display bars not working. I have purchased another thermostat. October 06, 2022 Does Not Come with Required Components. Wiring does not come with instructions. Unless you are prepare to play "Guess a lot" for several hours, do not buy this AC! The components are all lightweight and in my opinion, way too delicate to survive in a travel trailer! There is not way I have found yet to mount the Thermostat. I SWAG that you cut a precision hole in the wall and squeeze it in there, but it WILL NOT stay put on non-paved country roads. I am not sure it will stay put on paved roads! You open the control box to find the wires for the AC connection. After you secure them exterior to the box, you replace the cover. There are four wires with plug to plug into the side of the control box. Three wires are labled "12+ from supply", "12- from supply and to thermostat", and "12+ supply to thermostat". The fourth wire is not labeled and is orange. It doesn't operate the heater. EDIT - on another's advice, I opened the control box and inside, on the board, underneath the white cardboard, there are two spade connections marked "Furnace". Nothing on the outside. If you pull the delicate thermostat apart - using far more force than I thought warranted - you will find a small 3-wire screw-in wire connection. The two outside are labeled 12- and 12+. The inside one is not labeled. Situation: hooked up and AC working, but the thermostat display seems to be toast, fading in and out and different legs of the numbers not working. Fan seems to be high only, not high and low. Oct 1, 2022 Per Dometic website, you must get a control box (3316410) and thermostat. There are also no inside parts like the mounting brackets and bolts. The mounting bracket comes with the grill cover, but the bolts come with the control box & thermostate. That control box with that part number is the latest version that works with this AC. I STILL haven't received word if the kits with part number Dometic 3316230.000 will work with this AC. Therefore, as of right now, not installed and not working. You will also need to order this: https://smile.amazon.com/dp/B003BIR8GC It is the inside parts that mount the AC and the control box. It has the grill that covers the AC. The Thermostat has NO INSTRUCTIONS, NO WIRING PORT, and no clue on how to attach it.

We are so glad that we got the 15,000 BTU air conditioner to replace our old air conditioner which was 13,500 BTU. It works really well, cooling our 30 Ft Fifth Wheel. It's quieter then our old one but not as quiet as we would like. We had someone install it we didn't do it our self. Installation went well. We had some problems getting it delivered to us through FEDEX and had to call FEDEX ourselves to solve the problem with them. No fault to the Seller. The seller contacted us to be sure we received the wedelivery.

I bought this to replace the same model that came with my 2014 Grand Design Solitude RV. The original Dometic AC had quit cooling, although the compressor and fan still functioned. I wasn't happy with the first unit only lasting 4 years but wanted to stick with Dometic since I was doing the install. To remove the old unit I removed the inside filter and unplugged to connections. I then removed the four corner screws, then went on the roof and with help lifted the unit. We placed the new unit in, replugged the connections, aligned and put the screws back in. Make sure the silver tape seals back appropriately. This new unit definitely is not as loud as the factory installed Dometic. The inital unit was annoying. This one is more than tolerable. It cools as well or better. We are happy. Now if it will last more than 4 years.
