Coleman NDQ A/C

[Toyman]

Had my NDQ (Non Ducted Quiet) A/C with Bluetooth control installed yesterday in my Travato. It is a unbelievable improvement over the one installed by Winnebago. Great decision, said while patting self on the back.

Good for you and the pat on the back. It can make a stunning difference.

Congrats. Can you confirm it is this model?

We are heading there on the 25th with our 2018 K to get ours installed. Hopefully we will be able to fit the old one boxed to sell when we get back home.Already have a buyer

Only being sold and installed on Winnebago B's & maybe C's right now. I imagine it’s part of an agreement between the companies to quiet the air conditioner roar, both from the users and the A/C.

It appears to be available various places on the Net, e.g.:

Hi: Was it just a change out from the previous AC unit? Do you know if anyone can do this for me in Los Angeles? I have a PW Lexor with Dometi Penguin unit. Thanks!

The do-it-yourself a/c replacement I did was, in many ways, one of the easiest jobs I've had to do on my class b. Of course, what made it straight-forward was my replacement of a Coleman with a newer Coleman (not the NDQ) with same features (no heat pump/no heat strip). By staying with the same brand I was able to use the same mounting bracket, same control unit, and same wire harness plug. I could have even used the existing inside air grill but I chose to update that as well. The hard part was lifting the old unit down the new unit up.

The a/c unit rests on the roof on a foam gasket that seals water tight by compression when tightened down by 4 mounting bolts from the inside. There was some caulk on mine (though no caulk is recommended and I did not apply any to the new a/c), so it was struck slightly to the roof. I had to jack it up a little at a time over the course of 30 minutes to force it to slowly release to not damage the roof. Then, I removed the residual caulk and cleaned the roof area after removal.

If you replace a Dometic with a Coleman, it will install in the same standard hole, but will require a new inside air grill and probably a new control module. By control module, I'm not talking about the thermostat. It's a module hidden away under the inside grill that I believe communicates between the a/c and thermostat.

A professional, barring some unforeseen problem, should be able to do an a/c swap in an hour or two. The reason I ended up doing my own was the local rv dealers had about 3-4 week wait before I could get it in. So after a review of youtube videos on a/c install, I decided to tackle it myself.

I'm not suggesting you should do it yourself, because it can be dicey lifting the outside unit off and on the roof (I had the help of my 6'3" son in law and a very low-roof model rv). But rather to give you some idea of things to consider.

The lure of a more quiet roof a/c is certainly enticing. The higher efficiency and lower current draw are just an added bonus. It also might allow you to replace yours with a slightly bigger unit for more cooling capacity. I went from a 13.5K to a 15K that uses 1 less amp.

Good luck.

Has anyone confirmed this is in fact the same unit James referred to in video?
I called the phone number from link and they could not confirm. They just resell the item and don’t know specs or details of the products they sell.
So I’m wondering if that model or product number can be confirmed?
A google search on that number didn’t help.

Comments? Confirm? Opinions? Advise?

Any help is appreciated!

It has the same name, and the model number matches on multiple web-sites. I don't see any reason to doubt that it is the same product.

I can confirm it is same. I ordered one, installed it yesterday.

It looks like it used same compressor (although the compressor amperage is slightly less) and same cabinet design (I didn’t see any extra insulation or air route changes).
The major difference is the NDQ has a slower fan speeds. Also the old fan was 1/3hp the new fan is 1/7hp.

I called and spoke with AirExcel and they confirmed they slowed down the fan to make quiet.

If you examine the tags you will note the power saving on new a/c.

Reference the “FLA” full load amps for fan motor and compressor.
That is the amp draw during normal running.

Since I have a 2019 Travato I could have gone to Wichita KS to take advantage of the WGO program and pay $750 installed. But that ends in 2 weeks and I couldn’t make the deadline.

Also I’d easily spend a few hundred dollars on that trip. So the savings would have been washed out by travel expenses (I live 850 miles away).
So it made sense to me to order this one with free shipping.
I’m an A/C guy anyway and pretty mechanical with access to a forklift so installation was not a factor.

In any case I can attest that this is the NDQ unit.

Note: this is just the rooftop unit and does not include the ceiling vent control and cover.

I reused my same controls and ceiling vent.

If you want the digital vent cover it’s about another $225.

I’ll double check and post the part number on here for that.

But if you already have the Colman Mach 10 you can reuse your existing ceiling vent and t-stat controls.

If you want the digital t-stat with blue tooth, google part number 9430-720 to find prices.

That is the one for cool only they have versions for electric heat also.

RowieBowie is correct (read his post).
If you change manufacturers (as in going from Dometic to Coleman) I can pretty much guarantee you will need the ceiling vent and thermostat assembly for the other brand.

So consider that in your cost.

Hi: Thanks everyone for your posts!

@toyman

Can you share with me what happens when your setting is on Auto Cool Hi / Low? In my unit the AC cools to temperature and then goes to "off" I waited for it to come back on for 10 min and watched the temp climb by +5 degrees. I have a follow up call into Airxcel to see If I am missing something. Jason
