Icy breeze portable AC

[RiverDave]

First question does anyone own one? What do you think of it?

I was thinking this might be a good option to bolster the AC in the motorhome when it’s crazy hot out..

Second question I fucked up and didn’t order one in time for our Rv trip.. anyone have one they will either rent me or I can buy a new one and have it shipped to your house and I’ll take the old one?

We are leaving Saturday early am.. needless to say I’m having major concerns with temps projected to be 120 on Friday

 

[HNL2LHC]

Just a thought @RiverDave

 

[JB in so cal]

Where are you going that's its 120? Staying in town?

Why don’t you run the gen and the house AC?

 

[RiverDave]

The problem is getting out of town.. and we are heading to St. George on the first day which is hot AF there right now as well. It’s gonna take me two days to finally start getting into reasonable weather.. lol

With the dash air and both AC’s running I’d still bet it’s gonna be 100+ inside when we leave.. I don’t think the wife and kids are gonna like it.

 

[RiverDave]

That’s with them on.. lol. Rv roof airs really only knock about 15 degrees off outside temp.

That’s why so many people are going to mini splits..

I don’t understand why someone can’t just put all the mini split hardware in a large pancake package on the god damn roof.. I don’t give a shit what it costs is buy it.

[DRYHEAT]

If you have two ACs running plus the dash air and it’s still not cooling. I think you need a new motorhome. or maybe fix the AC.

Just curious, how many BTU are your AC's? You use the AC a lot, i wonder if they could use a service on them and some refrigerant added?

They always seem to kick ass when I have been in the MoHo, but it has probably never been much over 100 degrees tops, when I have been in it, and all the shades are drawn.

Whatever the bigggest ones they make are I believe. The front AC is being warrantied right now and I guess they are putting on the latest and greatest thing according to Trevor. I hope it shows up soon or we aren’t going anywhere.. I thought it was going to be installed today.

Then buy a portable unit from Home Depot and vent it out the window. Might need to get creative with the exhaust tube and the window to seal it off though.

Been considering that.. I have frameless windows though so it’s gonna be kind of a pain in the ass to figure out the venting like you said..

This icy breeze just seemed like a no brain solution to my problem.. I wish I ordered it a week ago

Gotcha, that’s not going to work. Do you have an exhaust fan that has a maxx air cover? Run the exhaust to that.

Shit that’s a good idea.. but I don’t think I have the vent covers on the roof.. I’ll go and find out tomorrow!!

Actually I think I just figured out my problem..

My motorhome had the washer and dryer but was converted to a triple bunk setup.. so they removed the pantry and washer and dryer and made 3 six foot long bunk beds.. in the middle bunk there is a short tube that is just taped off.. it’s the old dryer vent, I’ll run the exhaust out that.

So I guess the question now is how big of a unit can I buy before it trips the gfi or breakers on the cheesy motorhome outlets..

I bought an LG at HD for power outages. It works great to keep a room cool.

Even better, that’s a win.

 

[whiteworks]

You’ll be fine crossing the desert with everything on, do not shut it off at when your fueling up, it will not cool back down. I’d push a little further up to beaver as it will be 10-15* cooler than St. George. Beaver KOA has a nice pool and is a good stopping point for a night. Temps will continue to drop and be pleasant as you get past beaver and into higher country.

Have fun.

 

[LC925]

Comment may not help, but you might need to recharge the systems. I was able to cycle my AC’s in my 4018 Cyclone in the high 60’s while parked in Havasu during the summer.

However, I did buy these insulation sheets and cut them to window size and place behind the blinds. But obviously the 5th wheel didn’t have a large windshield like the motor home but still might help?!

 

[bk2drvr]

I met a guy camping at Pirates with a newer motorhome earlier this summer and he had figured out a way to put a damn mini split on/in it. I thought it was brilliant. He attached the condenser to a metal bracket he had fabed up to the back face of the motorhome and ran the line set through the back wall of the motorhome to two air handlers, one in the MB and one in the main area of the motorhome just above the side entry door. I think it was like a 12k BTU unit, on the small side. Needless to say cooling his motorhome is not an issue no matter how hot it is. I know its too late for this weekend but something to maybe look at in the future.

 

[Socalx09]

I got one when I was sick a few years ago to keep myself comfortable on the boat. It works if the vent is blowing right at you. I have only used it on a boat or beach. If we do any boating trips in July/august, we always bring it. I am not sure how well it would do as a “AC unit” in closed quarters.

If you’ll be back by July 11th at night, you can borrow ours. I think your RV trips are longer than that though. We are going to use next weekend- July 12-14 since we expect it to be 115+

It’s in chino, but I know someone on the board could get it to you if the timeframe works.

 

[Bpracing1127]

Dave, before you pack up turn on your ac,s with shore power 48 hours earlier to cool everything down. Set it as cold as possible. It will cool down at night. Also open all cabinets so the air in there cycles out too.

Once cool down it will stay 85 or so in there. Can you run all ac’s while driving? Bring house fans.

Once you hit St. George it will be ok. Night temps drop to the 70’s

 

[hallett21]

@River Dave

If you can keep the portable unit wattage under 1300-1350 you should be fine on a standard 15amp receptacle. Which is what I assume the RV receptacles are.

I would start cooling the RV down 48 hours prior like @Bpracing1127 said. But I would probably plug the portable unit into the house until you hit the road.

 

[BHC Vic]

I thought the weather was supposed to be nice in St. George.

 

[Riverbound]

all that’s going to do is blow humid air into the coach and make things worse. it’s essentially a swamp cooler that will put more load on the AC.

if you can’t cool your coach with the roof Ac and says AC you got bigger problems.

key is to get the coach cooled down prior to leaving. if you only had an air conditioned RV garage

Is that washer/dryer circuit unused currently LOL. That might come in handy for powering additional cooling. I second the vote for stopping at the KOA in Beaver, unless you have plans in SG.

 

[CLdrinker]

I’m surprised your motor home won’t stay cool with 2 ac’s.

This trailer and my previous both have a 15,000 and a 13,500btu ac’s and we can keep the trailer cool without a problem.

It was nice! LOF ruined it when he moved there.

I was thinking the same.
My ToyHauler has a 13.5 and a 15 wired into the trailer, plus another 15 (wired direct to pedestal).
Trailer was 75 all weekend in Havasu

I don’t understand this. We have a single roof A/C in a 32ft trailer and it stays less than 80 inside when it’s 110 outside. Surely 2 roof A/Cs and a dash A/C can do better than that?

 

[Dan Lorenze]

The key for me was a good size oscillating fan on the dash circulation all the air around the coach. I really helps the AC

 

[2Driver]

You really need a portable with 2 vent hoses. With one you are just drawing the same amount of outside air back into the coach.

The compressor needs to use outside air to cool it then put it back outside ie 2 vent hoses

Personally id just stay in a hotel that night

 

[77charger]

I’d vent it into the master and shut the door as best as can. Then open a top vent this should help rest of coach.

 

[GreenEnergy28]

My last coach struggled with the two roof a/c setup as well. The coach I have now has basement a/c and we love it. The downside is that it takes up storage space under the coach.
My Pop's uses the HD a/c to help cool his coach down. He sets it up in front of the doghouse and runs the duct to the driver's window where he made a plexiglass template. A little tape on the edges and he's good. Of course, not a setup for in motion.

You sure ? The single hose version I used to use in my shed/office used the hose to EXHAUST the hot air from the condensing unit, sucking air from the room.
The dual hose one I bought to eventually replace it, used outside air to blow across the condenser coils, exhausting through the other hose.
In both cases room air was being recirculated through the evaporator section.

 

[jetboatperformance]

Heres a thought ?

 

[Flying_Lavey]

Dave, id look into some of the supply duct insert things that are being made now along with possibly new grills. The combination can result in a large performance increase just due to being able to get air through the duct system much more efficiently.

You guys are saying the exact same thing. If air is exhausted, it has to be replaced from somewhere. That's what he was referring to by saying it's bringing air into the coach.

Get a 10k from lowes or HD and plumb the exhaust out the bathroom vent with a small wood cutout to cover the open portion, would take you 5 minutes to cut and make in the garage and trust me those 10k units work great. Until we get our genny setup when the power goes out we have one for our master bedroom that is 17x17 and it gets it ice cold in 115 degrees outside. (we used it in our 36' rv that had 2 airs and it helped beyond belief).

Yes

With one exhaust hose you are creating negative room pressure so the same volume of air you are sending outside is just being sucked back inside (say it‘s 105 out) the house through the normal places homes leak…under doors, around can lights in the ceiling…. etc.

Think about for a second you home ac unit condensers are outside, the blower units are inside. With a dual hose you are mimicking how the home unit works.

 

[whiteworks]

It’s only 5 hours or so from havasu to beaver, leave early and you will be fine. I’d be more concerned with transmission temps on the long desert grades in those warmer temps. We ran through all that area last summer in what the media was calling a “heat dome” it was stupid hot from Vegas to well past St. George. But my little v10 class c did just fine with only the dash ac and portable fans on. As well you will loose horsepower in hot air as well when you gain elevation just something to be aware of so you do not over tax the drivetrain. Slow and steady wins the race.

 

[SoCalDave]

Dave when you get back get this installed on both a/c units. I did my own for about $15 as I'm cheap. LOL
Also pull all the register covers off and make sure the boots are taped well to the duct. Mine was shit as it was factory sealed. Use metal foil tape on everything. Trust me, it made a world of difference in our 26' TT with one a/c.

I guess I mistook him, thinking he meant it was using the single hose to supply OSA in the same manner your vehicle does if not on re-circ.

Think about for a second you home ac unit condensers are outside, the blower units are inside. With a dual hose you are mimicking how the home unit works.

Yes I agree with that aspect being the negative of the single hose system, the pro if you will is the trade off for simplicity in many applications, especially temporary.

I used a single hose for several years in my previous home that lacked AC and it kept the bedroom sufficiently cooled for sleeping despite that negative aspect.
The previous owner had used a similar unit and it had an existing exhaust port which made it a simple seasonal setup. So yes, not efficient as the dual hose, regardless it worked well for our application.

 

[2Driver]

Im tempted to try one of these for the camper we are getting. It has no ac at all.

So I guess the question now is how big of a unit can I buy before it trips the gfi or breakers on the cheesy motorhome outlets..

Most all the portable AC's are designed to work on a standard 15 amp circuit. Just make sure to plug it in direct to an outlet, and the outlet shouldn't be shared with anything else in the coach pulling 120v power. Make sure the outlet isn't on your inverter!

If you need to use an extension cord to make it happen with the right plug, keep it super short and 12 gauge or better.

You might want to get a good fan to leave running and blow the added AC air towards the passenger area of the coach. If your W/D area is all the way at the rear like most, you wanna move that cold air up towards the front where the people are riding

Already covered in other posts, but ... - Make sure to pre-cool the coach all night prior to your departure, as cold as you can get it. Everything inside is like a heat sink, the colder it all is, the easier it will be for the coach to try and maintain the temp when you depart. Obviously, plan to drive early AM or at night to avoid the hottest temps, there's a 30 degree swing between 5am and 2pm !

I have one, They work best with block ice or frozen water jugs.

as far as a portable unit, probably 8000 BTU would work with the circuit you have.
