Вставка
- Опубліковано 28 лют 2019
- In this episode, we replace our old 13.5k btu rv air conditioner with a new Coleman Mach 15 15000btu RV air conditioner. It is the same install as for a 13.5k air conditioner. Follow as we walk you through the step by step process of replacing an RV a/c.
We are a couple that have decided to semi-retire early and enjoy travel and adventure while we are still able. Follow us as we prepare for our new life, selling off our home and stuff, and prepare our rig "Herbie" for full time living.

*Great product **Fastly.Cool** so far*
Hi , Thank you so helpful , I replaced mine and observed all your directions, You made it so easy , thanks a lot again !
This video was extremely helpful to me. I have the identical unit as you were replacing and had sooooo many questions about the install. Well not anymore thanks to your video. Thank you so very much it was a life saver.
Thanks!! I was telling a friend yesterday that I should have done more of these how-to videos, but when I go to do a project I just want to get it done, not waste time trying to record it. Having said that, I know how often I have turned to these videos for help. Thanks for the kind words!
Currently replacing our forward 13,500 with a 15. 6 years ago I replaced our rear AC. But had a couple questions cause I couldn’t remember. This video answered them. Thanks!
This is one of the most helpful videos on any topic that I've ever seen. Thank you
Thank you! I plan to order my own and install. Local RV shop quoted me $975 parts and labor. I replaced my own converter last year with about this much ease and saved $250.
Absolutely...only really challenging part is getting it on the roof!
Pensacola Rules My shop landlord had a forklift. I did the whole job by myself in less than an hour. Thanks again.
I found this interesting. It’ll be a great future reference video for everybody with the courage to replace their own ac unit. Thanks!
Thank you! We haven't been doing videos for a bit as we have been busy moving full-time into our RV, getting our house sold, and adjusting to our new life! I hope to have new videos out soon, I have a water pump that is going to be installed here shortly and I will show how I do that as well!
I'm literally installing a Coleman Mach today. Replacing the old one. I have pretty much the same setup. This video helped me out alot. Off to the hardware store to grab me some aluminum tape. Good job on the video. 👍🏼
You bet!! We are workamping in Minnesota right now, and it's been HOT!! AC still working like a champ!!
Thanks man!! Getting ready to order a new 15000 for our RV.
This video was awesome, just changed mine, plug and play. Hardest part was getting new on the roof, and old off (used a skidster). Thanks!!!!
We replaced ours today. It blows my mind that there's only 4 screws holding that thing down, but I'm not going to complain. I do need to figure out some kind of ramp system to get it up to the top next time though (when we replace the back one, only replaced our front 13.5 with this 15 this time). Used pulleys this time, which wasn't too bad, but still sucked when we got it to the top of the ladder.
I imagined using a couple of 2x6's as ramps, but my brother in law that helped said we should be able to rope it up, which we did. However, if I were to do it again, I would leave it in the shipping crate to avoid any chance of damaging the unit. Congrats on your install!!
it was the info I exactly needed to replace my ac unit mine is the same model Thanks!!!
Great. We upgraded ours for the very situation we are in now, we are hooked up to 30 amps and really can't run both A/C's, but we are able to run the larger 15k unit we installed. It is just keeping up. Glad it was useful!!
Great job it did help me, thank u
Why not just do all that from roof? It's so much easier to take the cover off ,instead of reaching blindly
your video has confirmed my thought about how easy it looked to do and gave me the confidence to do it myself so thank you. only thing i can complain about was i had my phone turned all the way up and couldnt understand everything you were saying
Thanks! I was pretty new to making videos when I did this, so the audio wasn't great. Of course, now that I have the equipment I just don't have the time...ah, life!!
Did it mot come with a new circuit board (that white box that the thermostat wires and power goes too?
No, I think you may have a different or newer a/c. In mine, there is a galvanized box that the wires go to, but there is no circuit board in it, just a junction box for the wires. That box did not come with the new unit.
How do u add a heater element to that?
Excellent vid. Gonna replace my 15,000 with the power saver 13,500 in my 21 footer. Should be a simple plug in like yours.
Thanks
Yep, it's surprisingly simple!! Good luck!!
great info. thanks
Super helpful vid
Thanks, Seth! I would have done more how to videos, but I discovered that I don't have the patience to slow down to try and video the repairs. Thank god for Tito!! (You'll have to look him up) ☺
The electrical box you took off with the wing nuts, is that common in all a/c's when you put the new unit on?
I don't think so...I think some newer versions may have these mounted elsewhere, but of course I am only familiar with the one I installed and my rig is 17 years old. I think I saw different set-ups on some of the videos I looked at before taking this on. You might look at some other videos for other configurations.
@@pensacolarules4228 Thank you Sir for your information and video. It was helpful!!
Thank you for this video! I do have one question, did you use any kind of sealants/caulks around the square opening on the roof when placing the new unit? Or is there some sort of foam/gasket there? Thank you again.
Mine came with a foam gasket. Other than that, I did not use any caulk. Even the screws on the cover would only leak down into the drain pan. Safe travels!
How big of a difference did it make going from 13,500 BTU to 15,000 BTU ?
Not a lot, really. It cools a little faster, but not enough to really notice.
What size screws
You say that you live in it full time. So do I. Is it ok to leave the bedroom AC running 24/7 on a medium level. I have the old knobs. Asking bc I get worried about running it 24/7 and burning out the AC unit. The rv is I my 2 yrs old. Please help me understand the best way I should go bc the rv stays hot I side with only running one of the units
Ronnie, I am not an RV or HVAC person. I would recommend calling an RV repair person. I would believe that you will eventually burn out the bearing running it non-stop. Your best bet would be to try to move it into shade, or consider putting a cheap window unit in the bedroom and give your AC a break at night. Or do like we do and move north in the summer! 😏
Hi, I have a Coleman Model No. 7335B891 that needs replacing. I plugged in my model into coleman/airxcels compatibility chart. Only one "compatible" model popped up; Mach 15. When i click on it, it says NOT A DIRECT REPLACEMENT. NEED CEILING ASSEMBLY. Doesn't it come with a ceiling assembly?
Shawn, I am by no means an ac expert, just a full timer that installed my ac in my rig. However, I think the interior vent or control is sold separately. I know mine did not come with one.
New unit came today. Unit only nothing else. Did you use your old flange on the inside ceiling of the unit for the four long bolts or did you have to purchase a new one?
I reused all of the original hardware inside. Good thing, I suspect those bolts would be hard to find!!
Did you use a new foam gasket or the original one from the old AC unit? Reason being is I am installing a new Mach 15 when it arrives.
I seem to recall it came with a new gasket.
What kind of seal for the ac on the roof?
I believe it came with the ac. I used dicor to seal to the roof.
Got it. Turns out that ours is so old(15 years old) that we also would have to get a new thermostat and control box. Also the ceiling assembly is separate.
At least installing looks easy.
Another question: Can we reuse the same wiring for the thermostat from the old one?
@@TheMegamanDX Should be able to, even if you change the thermostat out, wires are wires. Just need to double check and make sure the right wire goes to the right function.
Is the hole size standard?
Yes, I believe they are 14 inches.
@@pensacolarules4228 Thank you

I'm putting a Coleman mach15 in an rv originally had a DuoThem, where can I find the right adapter ?
I am not familiar with the DuoTherm, but I'm sure someone has an adapter. The hole is probably the same, and you might just need a wiring adapter if I had to guess. Sorry I'm not more help.
@@pensacolarules4228 After more research, I learned if putting dometic in an rv that used to have coleman, all you need is the wire plug adapter, but if putting coleman in an rv that had anything else, you have to replace the lower control board and T-Stat. Coleman will not interface with dometc style .
SO I have to replace the entire system
Nice work. I just bought a Coleman Mach 3 9200 btu for sprinter and I know I’m wondering if the 14 inch gasket is included. Or do I have to buy it separately?
They usually come with the gasket. The only extras you would have would be the interior cover panel if you needed one, or a heater if you wanted one. Thanks!!
What size bolts did you use??
Honestly don't know, they were in the original a/c and I just reused them.
i\m in pensacola too , are you still living in pensacola?
Actually, we have never lived in Pensacola...LOL!! While I did live in Panama City from age 5 to 12 (Air Force Kid), Pensacola Rules was a concept my wife and I developed before we were married on a Christmas trip to Pensacola. We learned how to live spontaneously when things go awry during that trip. Thereafter, any time things weren't going to plan or we changed our minds and priorities mid-stream, we declare "Pensacola Rules" and go with the flow.
We are, however, developing an acre of property south of Perry Florida that we bought, turning it into a winter home base for us!
Take care and stay safe!!
Helpful vid....but I wanted to see you turn it on and hear it blow.. 😂
I figured you had heard me blow long enough!! :)
I am in Pensacola and would like to contact you. Thx
Joseph, we actually live in Newton Kansas, Pensacola rules comes from a story of our visit to Pensacola. However, I did grow up in Panama City until I was 12.
At least you got some hair.
Not even sure how to reply to that!! :)
