Chris, received my new GREE this week and started the installation process today. What a story, started yesterday with hooking up the Airstream to move it to my shop, wanted to use my forklift. Hooking it up I had a nest of wasp under the propane tank, got hit one time, disposed of them. Today, moved the camper to my shop and climbed on top, with yellow jackets flying around. My wife and I had 2 cans of spray and we were busy spraying. Finally I was able to take the old cover off and had 6 nests, lost 2 hours fighting them, no more stings.
Finally removed the old unit, cleaned up the caulk from the drain pan. Installed the new unit and moved it back to the house, started it up and you are correct, extremely quiet, cold and strong blower, 99% happy with this AC. The only complaint is that I had ordered a white unit, received a black one. Couldn’t wait on a replacement, needed the AC working. Thank you for the video and I did use the code. KY Ken
That sounds absolutely awful. I know when I worked as an HVAC technician I kept the can of wasp spray for that exact reason but anytime I would open up a cover and things would fly on me. I would takeoff running lol glad you got the new unit in and running. Thank you for the comment and using my code. I would bet if you reach out to the company they will send you a white replacement shroud.
Chris, I’ve had the GREE running for 24 hours. It is warm here in KY, but I’m not seeing the cooler temperature that I was hoping for? At the register it is blowing about 60 and the outside temperature is 87, the camper is 79. What temperature are you seeing from your GREE? Thank you for responding.
Standard air conditioning pulls “20 degrees” so you’re right where you are supposed to be.
We installed these on our Prevost Coach and you were right they are super quite! Thank you so much for the video! It was because of this video is why I chose the Eco Cool AC units and glad I did.
I really appreciate that!!! Yes they are amazing units
They are quite quiet!
I just finished upgrading our solar system to 1850 watts of panels on the roof, and 900ah of lithium batteries. I bought a portable ac which I vent using one of the windows in the rv. It's rated at 8000 btu's. My reason for purchasing was so I could run it in our bedroom overnight just off the batteries. On a hot day (90's) it cools just enough so the inside temp is tolerable, not cool. I'm thinking this Gree unit would meet my energy consumptions goals, while also cooling the entire trailer down, and not just the bedroom. Great video. Just stumbled across your channel today.
Sounds like a nice build you got going on! Sound like it the Gree is the answer for sure!!! I have a new video coming out today on it again as it’s just an amazing unit. Only 10 mins long. Posts at 4pm eastern so be on the lookout
Very nice...so it seems like its a mini-split type machine built as a roof-top model. Which is fantastic!!
It’s truly amazing
Thank you..i just opened up my phone BAM
THANK YOU
Yes sir. Thank you!
I was just looking at the spec sheet for this unit. There's a graph showing when abient outside temp is 70 degress the unit uses about 875watts, at 80 /1100 , at 90/1200 and at 100degrees it uses bout 1400 watts. Can you please test this when you get a chance this summer?
I will be doing exactly that!!! I wish I could just test it but it’s just a time thing. Will definitely report back
What did you do with your condensate It looks like you're just eliminated the very nice drain that was there before Now your water is gonna drain all over the top of your coach and down the side staining it
I'm down here inthis unit draws a little over 1400 W at a 100° day ambient. I don't see much change between dominic penguin and this
99.9 percent of RVs just drain in the roof. Not going to be an issue. Not going to stain anything. These units are definitely more quiet than dometic and way more efficient. I’ll be doing my own tests in the summer.
@@bobrobi4328 where r u at? How long have you had your gree and is it that much quieter than your dometic or houghton?
Chris. Was at the Hershey RV Show today and saw the Eco-Cool in action. Boy is it quiet. I want to order one but have couple questions about your install. If I have one zone do I still have to wire the old circuit board in order to use the furnace or does the Eco-Cool connect and integrate with the furnace for one zone application? Second, call me anal but I would really like to use the integrated condensate drain system on my Airstream (25FBT). You stated you didn't use. Do you know where, if anywhere, I can get the cups? I assume I'd have to cut a hole through the gasket which I'm comfortable doing. Thanks for the help!
As far as the condensate situation goes. The idea that Airstream has with the condensate lines running through interior wheelwells can be visually appealing, but if a line backs up and you don’t know about it, you’re gonna have a nasty problem on your hands. Best to just let the water drain off the roof naturally just like all the rain does and every other RV does. if you want to use the condensate situation, you’ll definitely have to do some custom work. The Eco cool unit cannot control your furnace so you would still need that to go to a control board that goes to the thermostat. The heat pump feature does extremely well. Last winter I was maintaining comfortable temperatures down to the mid upper 20s. Once it got below that big gas furnace had to supplement heat.
Great video!
Thank you guys!!
If your using it with 3000w inverter and minimum 300ah of Lithium batteries, you need to add a soft start to dampen the LRA of 48.5a to something less than 24a. Looking at the wiring diagram it's clear from the wiring diagram that there is no soft start, the the type that significantly dampens LRA rating. Otherwise the Lithium battery can't supply the huge compressor start in-rush current. I had to add a SoftStartRV to my Gree to get it to work from my 13vDC Lithium battery/3000w inverter system. The SoftStartRV did solve the compressor in-rush issue by cutting it in half. I don't understand why a soft start wouldn't be automatically incorporated to reduce the LRA to less than 24a for a real game changing RV air conditioner on 120vAC or 13vdc power systems alike.
So I’ll say this… my setup with my Victron multiplus 3000kva inverter… no problems starting or running this as is. Of course soft starts are always good to add
@WhyNotRV The key is how much Lithium battery capacity you have, if it's +400ah you probably won't have any issues because a large battery bank can supply the +350a compressor startup power. The Eco-Cool LRA rating or maximum amp in rush current needed at compressor start on 120vAC is 48.5a, which translates to 5820w or 450a at 13vdc. A Victron Multiplus by the way only has a surge capacity of 5500w. So just because your able to run your Eco-Cool without a soft start now doesn't mean you won't have any issues with your Multiplus and Lithium batteries running it.
My battery bank is over 1200ah and the multiplus has yet to have an. Issue starting it. I appreciate all of your input and may still add a soft start to reduce the stress to the multiplus.
Obvious answer is that not everybody needs it, and it increases the purchase cost. No brainer.
I’m sold
It’s been a great unit for sure. I’ll be doing another update video
great video on the gree eco cool rooftop, thanks so much, one question is it normal for the unit to run continuously on a/c mode with fan on auto all night? I thought it would run and stop and run. Thanks so much
For the settings you’re saying… the fan should come on and off as needed but also circulates to maintain equal temps. It’ll ramp up and down as needed be. Thank you for the kind words
Does your new Gree AC make a beep each time its compressor cycles ON and also beep when it cycles OFF even if you are not touching the control?
I’m going with no. I sat in the rig a bit today just to listen for that happening and never noticed it. It beeps any time I make and apply a change to a setting….
What is the difference between the Gree and the Tosot? They are identical and the Tosot is about $300 less. I've heard they are made by the same company
Premier products is the distributor I worked with and who you would go to for any issues. The Tosot does not work with you for any issues. No matter of its initial firment and parts to ongoing service, premier products will take care of you
Brilliant! 🎉
Thank you 😊
Nice video! I'm looking at putting a new rooftop unit on my 2001 Airstream excella 30 foot. It still has the factory dometic unit. It looks like this product has the same design as a company called Tosot (looks like they distribute Gree products). Still very little in terms of reviews on these units. I'm stuck between this, a Rec Pro Houghton unit, and just going to a Coleman Mach 8. Any advice you have? I definitely want a unit with a heat pump. I like that this Gree unit has wifi control as well. I only have a single AC, so something efficient, powerful, quiet, and intuitive is important. Any input would be greatly appreciated!
Absolutely!!! I 1000% recommend this over any other unit. I have used and owned the rec pro houghton unit and it comes close but this unit is definitely #1. Gree is the world’s largest HVAC manufacturer, they have been working on this technology for years ahead of their competitors. I love it and everything about it.
@@WhyNotRV Great to hear. I've only hesitated to replace my unit because 1. It still works, 2. There hasn't been anything on the market I've seen that would be a really worthwhile upgrade (all the tech seems to lag behind on rooftop units). Seems like this one may be the ticket. Let me know if you have any other updates on testing. Thanks!
Ya I do believe another 2-3 years or so they’ll get even better but right now this is definitely the best thing in the market
Links don’t show GREE unit? Also the supports for the steps on your A’stream - info please?
The Amazon link is the same unit just rebranded. The company fulfilling the gree brand which is the main parent company hasn’t launched on Amazon yet but should be soon and I will update the link once that’s done. The steps i did a video on. They’re Torklift Glowstep Revolution.
Thanks. Really enjoying your channel. Fellow streamer BRN 6777
I appreciate it Tom! Thanks for watching
Also, not sure where your other comment went but yes this vents are on the front and back of the unit and are amazing. There’s also a center circular vent you can open for air to go straight down. I keep it closed and there’s actually no air that escapes past it unlike other vent styles that aren’t well sealed. This has little foam insulation on the back and is very well sealed.
I deleted my other comment because I found the answer and did not want to be to worrisome. But in the mean time, what about installing a Soft/Easy Start on this unit. Is it necessary? If needed do you think installation would be fairly straight forward? I ask because this will be acquired soon and I want my ducks in a row. Stay safe & level@@WhyNotRV
Hi, I didn’t see what you did with the tube that goes through the wall in the airstream. Do the cups from your dome medic unit fit on the bottom of this one and route the condensation through the same tube?
I just tucked it into the ceiling. It’s not being used. The drain cups from the old unit do not fit. I was thinking about 3-D printing custom ones but it doesn’t bother me to let the moisture from the condensation drain off the roof like 99.9% of RVs.
So I’m very new to this and I’ll probably set up my van w victron. This is a AC unit so what part of the Victron set up converts the battery power to AC is that a problem at all?
Q-2 Do you know anything about if I should even use 12 V or should I just start with 24 V or 48 V?
Thanks,
Bill
Thanks for watching. First, the Victron Multiplus or Quattro are what convert DC to AC. In this rig I have the multiplus-II, it starts and runs this unit no problem. Second, to answer your question about 12v, 24v or 48v I need to know a lot more about your build. I have videos that talk about all this stuff. ruclips.net/video/ZlvN7gbsiqk/видео.htmlsi=0kQtZa_W4kBXQPCe
Where do you get the longer bolts? I notice it says you may need 7.5 but they don’t give size / thread ?
If you need longer bolts I would just take one of the originally packaged bolts to ace hardware or something like that. They have thread checkers there so you can confirm the thread size and get the same in a longer bolt.
How do you turn the beeping off on the buttons
I’m not sure there is a way….
any chance you coul do a in-rush test on that unit and post results here? thank you
I will add that into my Update video which I’ll be doing in the next month or two with some summer heat to show its cooling in real warm weather
@@WhyNotRV Sounds good. What size and brand inverter do you have?
I have a Victron multiplus II that is a 3000 VA inverter
@@WhyNotRV that's what i have
Ya itll runs the one perfectly fine with no issue
My airstream has a slightly curved roof, does the gree gasket seal the unit even with the curve?
I’ll say a few things here. First off, yes you’ll be fine. I have had mine installed for almost a year now and it has done great. Second, while airstreams are slightly more curved than other RVs, majority of rv roofs are curved, some worse than others but that’s why it’s a foam gasket. Applicable for all RVs
@@WhyNotRV Thanks for the info, now I just have to get it up on the roof!
Easier with 2 people and 2 ladders side by side. One step at a time
Helpful video, but I can't seem to find these Gree units (or the 48 volt version you show in your other video) for sale anywhere. Are they actually for sale in the US yet? If not, any idea when they will be?
I’m not entirely sure if they are or are not for sale yet but I can try to find out for you.
@@WhyNotRV I submitted an inquiry via the company's US website, but if you can gather any other info, I'd really appreciate it! I'm assuming you're still happy with the unit? I've been trying to compare it with the comparable Recpro, and your video makes it look as though the Gree is a nicer unit.
I’ve had the repro unit before in another RV, and this unit is definitely nicer, quieter and better features.
Does this unit discharge conditioned air to the rear as well as the front? My rv has
only 1 unit that is toward the front of the rv and I would need it to blow rearward as
well as forward.
It blows forward and backward which can both swing up and down to help with air distribution. There is also a vent in the center that would blow straight down. I keep that one closed but depending on your needs and setup it’s available as well
Is there an easier way to control the furnace without having to do the modification with the board from the old unit? Or can I just take my AS to you to install mine? Lol😊
First off, thank you for watching. Second, depending on your location, the company who sells these either offer free shipping or free installation at there Elkhart, IN facility. If you wanted me to do an install unfortunately I’d have to charge for it. Plus you’d have to drive to SW VA. I’m currently working with the company on a workaround/easier solution for people. I’ll be sure to update this comment thread with that if we can figure something out plus I’ll probably do a follow up video on that.
@@WhyNotRV thank you for responding. I though you were in Texas. I thought I heard you mention Texas in your video or one of your videos. Have you compared the decibels of this unit vs the Houghton? Oh and the amount of watts or amps used to run both?
I had traded in my big Montana and got my Airstream in Longview, TX and I’ve driven in and through Texas multiple times over the past few years. But that’s about it lol. The rated db that Houghton puts out is 54-59 for the interior and they are quiet. But the Gree is rated at 43db and is significantly more quiet. I don’t personally have a decibel meter to know for sure but it sure is quiet. The wattage I went over at the end of the video. I think around 20 minutes range. I left my back bedroom unit stock for now and only have this unit as the center main unit. I’m going to test it this upcoming summer by itself and see if I ever even need that second air conditioner. If not, I’m planning on removing it and installing a nice max air fan instead. The way that the vents and either end, throw air and help circulate through the RV more efficiently. I’m almost betting that I won’t even need that second air conditioner. Maybe if I was in Key West in July. Lol. Right now it got down to 33° last night and the RV stayed at 60°. The heat pump was pulling temperature all the way down and doing great. I will say I’m going to be testing it in below freezing temperatures here in another couple few weeks and will be doing a follow up video on that.
One more question, we’re you able to use the condensation drip lines that keep the water from running off the roof? If not, do you know if they will entertain making an adapter for airstreams that will allow using those drain hoses?
I couldn’t stock but if that’s something important, I thought about 3D printing little adapters. For me, Personally, I’d rather it run off the roof, one rain storm puts more water on your roof than an AC does all year probably. So it’s not like it’s damaging or hurting anything. While the tubes coming inside have a chance of leaking and causing issues in unknown or unreachable areas.
Have you taken sound readings (dbs) comparing your old unit with this new A/C unit? Curious the quantitative difference. Thank you.
You know I really wish I had a decibel reader and may invest in one just for the comparison. I will say that well beyond a quantitive difference there is a extremely noticeable difference between the regular air conditioner and one of these units. It is insanely quiet inside.
@@WhyNotRV there are phone apps for that! ;) Probably not as accurate as an handheld sound meter, but better than nothing!
You are absolutely correct. I’ll do that and do another short update
What was the ambient temperature outside? And how many minutes did it it run when you were showing the 900w? Both of these can play a significant role in the Max amps. Specs say 12.5 amps.... Just wondering if it would get that high with hot enough temperatures outside hurting it's efficiency.
This was October in southern Virginia so it was pretty mild. I’ll be doing full in depth tests this summer in some extremes.
Awesome. Thank you for the clarification. If possible it would also be very interesting to see how well the heat pump function works. If it's able to put out any heat 32° or below.
And thanks so much for your videos. They are very informative and thorough.
I did a follow up video here during winter. Down to about 24°. It will keep producing heat but very minimally. It was able to keep the RV around 60 I think so I use the furnace as a back up but the heat pump being able to be main source of heating.
Very good. Were you able to notice the max watts it was pulling atthat time?
I did not. It was overnight.
Thanks for the video. Quick question: What's the distance from the roof to the bottom of the inside unit?
On the inside. From the ceiling to the bottom side is 3.77”. If you’re asking about something from the roof down and in O couldn’t really tell you. Depends on thickness of your ever roof
@@WhyNotRV Thank you. You answered my question
Absolutely! Glad I could help and thank you for watching
Thank you. I own a 1998 Chinook Concourse Class C and I'm 6'1" tall so this AC with that much thickness from the roof would not work for me. Otherwise I would get one. @@WhyNotRV
Hard to find rv style units that are really any less thick. Minisplit options?
I'm getting ready to pull the trigger on purchasing one of these AC units. Have you had a chance to use it for more than a few minutes. I know that my ACs with soft starts will start with a low watt draw and ramp up over about 5 minutes. Are you still seeing less than 1000wattts being used after 10 to 15 minutes of use? Also how do you compare the airflow to your old unit? Is is the same or more on high?
Hey Jeff, excellent questions here. The unit has now been installed and operating for about a month and has been maintaining heat as my overnight temperatures are near freezing. At 33° external temperature it is still in maintaining be 60° inside the RV without issue. Same wattage draw of that 800 to 900 range. According to everything online in their literature, the heat pump mode should be more of an energy drive in the air-conditioning mode. I won’t know about full air-conditioning mode until mid summer in terms of its real water drop during high heat days. But based on the testing I’ve done so far I have great faith in the unit that it will stay around that 900 W range or so. The CFM is a bit higher than the stock unit when the fan is set on high. I believe the pneumatic is 280 CFM range and this has 320 CFM.
@@WhyNotRV Great to hear. If it works as good as I am hoping I may not have to do a full blown mini split install. Thank you for the video.
I personally can’t wait until this upcoming summer and test it all summer long. My hope is that it is actually so efficient that I don’t even need the second air conditioner on my rig and I will remove it and replace it with just a nice max air vent fan so that I can enjoy the natural fresh air when in the right areas
I need a professional opinion I looked at all 2002 Ford admiral the interior was pretty beat all appliances was the original nothing seemed to work both AC unit on the roof was not working water lines were leaking at the fittings water damage at the bedroom slid out the generator was running but I don't think it was putting out he had a generator running and hooked into the shore power I am not an expert I think the whole interior needs completely gutted and all new appliances best seller was talking about 9k I'm thinking about 3k would it be worth trying to replace everything
Biggest thing with a deal like that is of course it would be a full gut job. It’s a lot of work. What other damage is there you can see. Subfloor? Walls? Roof leaking? The value is really just the chassis and motor.
@@WhyNotRV 6.8v10 35000miles ran smooth frame good they said they replace the subfloor put down some cheap wood and it was all coming apart
Yeah, so the question is do you feel that for $9000 The frame and engine are worth that or not. Because otherwise it’s basically a full gut multiple months rebuild. I think if you get it for the right price you’re gonna be having a super fun project ahead of you that you can be proud of at the end and have a great little rig.
@@WhyNotRV thank you for the feedback
absolutely! Always happy to help
Update: Purchased the ducted version of this AC (using your discount and thank you) but honestly the ducted version of this unit is not ready for PRIME TIME. No installation guide, no user manual, no nothing; they expect you to know everything about it. After back and forth emails with the support guys I was able to get it to work with my EasyTouch RV thermostat and it works but I'm measuring over 32 amps of in-rush current which in my opinion is SUPER HIGH for a unit advertised as not requiring an EasyStart. My old Coleman Mach 15 was measuring about 18 amp in-rush with MicroAir Easy Start installed. Although I like the lower power draw while on AC mode overall I'm very disappointed with the whole experience. DUCTED version has lots of potential but in my opinion is not ready for prime time.
I appreciate this addition here. I have no experience with the ducted version. I’ll be doing a updated video here in the summer with Realtime use to show power drawn what not
@@WhyNotRV cool. i’ll probably do a walkthrough video of my install experience and share some data of it as well.
I agree, Just by watching the video and looking at the ducted ceiling mount.
I plan to purchase the model in this video and engineer the ductwork to connect to the drop down flex duct. Hopefully I'll have both options for air flow.
Wow…..I appreciate that. I just purchased the ducted version too. I haven’t taken delivery yet, but have already been searching for videos and installation info for it, and haven’t found anything. That doesn’t put me at ease…..
It’s a very simple install. The pre existing thermostat and function is the only tricky part. But the unit itself is very simple.
Beware! Premier Products is not honest! I purchased two of these units. The remote controls are not independent so they're worthless if you have more than one unit. The bolts they include in the kit are too short for many RV roofs (3.1" thick roof max). They are a metric thread that is nearly impossible to find in the appropriate length at common hardware stores. They shipped the units via a regular carrier instead of freight. The units are too heavy for most people so they get slammed around in the shipping process. The packaging for both units arrived completely destroyed. There were scratches and rub marks all over the outside of both units. I contacted Premier Products and they did nothing. I tried leaving a 3-star review on their website, which was more than fair, but they won't publish it. I left a second review, same thing. They moderate their reviews to only show 5 stars. This is just another company that will take your money and then hide from you in the event of an issue. Please take my advice and find somewhere else to spend your money.
I’m sorry to hear that you had this experience Travis. I know many people who have emailed premier products and they will immediately send them the correct size bolts with their units. They do have the correct size for 5th Wheel and motorhome roof. The bolts that come with it are typically for vans or Airstream And smaller travel trailers. They’ve been great to me and to my viewers.
False advertising says no soft start needed and variable speed inverter based. This is bs
What makes you say this is bs?
Hey Chris, love your video and your channel. 👍👍👍How could we contact you? Thank you.
