Portable ac blowing not cool air

It's a 14000 btu. Week old. My last one did this too. I turned off for a few minutes and started again. Seemed cooler. Gotta check on it later.
Wtf? No warning lights on

Does it have a drainage plug? My portable a/c doesn't even list that it's a dehumidifier so at first the tank filled then the a/c turned off because it couldn't collect anymore water. If you find this is the case; I connected a little bendable hose to drain into a plastic bottle and I have a few of those to swap out it's easier than opening a drainage screw into something to catch the water.

No its new and filter is clean. Filters are clean
There is an auto shut off and indicator light for full resevoir but I unplugged it upon install anyway so it wouldn't be a problem

Did not appear damaged. Worked fine for a week up until now. Turning it off for a few minutes and back on had it blowing cold air again. However I just checked temp remotely and it's not good. 95.

Ok. So I've been running ducting from the ac to another room and into a charcoal filter.
It hasn't been a problem til now.
I unhooked the factory hose from my ducting and it's working good now.
Actually the fucking negative pressure on the tent is way stronger now. Knocked my fucking fan over...

I had about 25 feet of run with 2 shitty 200 cfm duct fans and a 420 cfm at the end. Apparently that wasn't enough.

So now maybe I can run a shorter line with just the 420cfm. Will test tomorrow I guess. Got the ozone generator running cause now I'm unfiltered

Dangerous. Only 4 weeks til harvest. Fuck me.

Isn't the ducting just bringing air from outdoors to cool the element and then pushing that hot air out the other duct to outside? Why would you have the AC ducting passing through a carbon filter? I don't understand how you have it hooked up.

It's a single hose. So it uses air room to cool the machinery and exhausts it out with the heat through a single hose. It creates a negative pressure on the tent and acts as my exhaust.
I need to move the heat to another room .I also need to move the exhaust to the filter.
I can shorten it a little. I will test this later.

Yeah I found a couple of the instruction sheets from portable ACs, never owned one myself, and indeed they do just use the room air instead of outside air, meaning they suck the cooled air out of the room and waste it outside. It's like the stupidest design imaginable. The obvious solution is two hoses. I would put another hose on wherever the intake is, if that's even possible. I can certainly see why you have a lot of negative pressure in the tent. I just have AC in the window of the room that the tent is in. No negative pressure aside from the slight amount caused by the PC fan that vents the tent. For one the size of yours, I guess you'd need two or more PC fans. Then I just remove the smell with an air purifier in the room with pieces of carbon pad zip tied over the back.

Researching now. May trade for dual hose...
If there even is one that uses 2 hoses in the window. They're also very costly and I doubt you would need as many btu of cooling power as the smallest ones have, 8000 btu. I cool a whole room with the smallest window AC available, 5000 btu. Anyway, I'm sure you'll work it out eventually. I hope it doesn't cost you too much in the process.

The window ac would have to be converted. To do it right it's a bitch. You have to box off the exhaust. And then box off the part that cools it. I'm seeing dual hose on walmart .Com same price range as this one...

Warning, my old active air dual hose 14k btu sucked major ASS!!!! couldn't even get me sealed 1800w 8x12x7 room below 77* no matter how hard it tried. Now my current and previous ac to the active air is a single hose 14k btu LG unit. That beast gets things a bit too cold, so I'm always dialing it in...in a food way. Last 2 weeks I give them.70* lights on and 63-65 lights off temps. Normal lights on temp is 77* weeks 1-4, weeks 4-7 get 75*.

Don't buy the active air dual, garbage.its why I had to dump my sealed co2 room and go back to my old air exchange ways.
