Thought they had vinyl everywhere . . . never considered desert heat. If it wouldn't create an eyesore you could raise the garage door and put in a temp wall to fill the opening . . . cut whatever holes you need in that. Or remove a window sash and install a temp panel with needed cutouts. Just a couple ideas . . . depends on the structure and how it sits on the lot I suppose.
Need advice on portable 3 ton ac unit for a ten light garage grow

You can try but rebuilding the wheel cause you want to, but it isn't gonna happen
You aren't the first grower in AZ

I think your spending 5k on ac that’s not gonna work. Do you have windows in the garage? You could frame one in and run the line set thru there. Pay a mason to come out and remove one brick that could easily be replaced later. I’d you have two windows could do 2x24k window units, or even 2x18k window units, both will have way more power than the portable. I’d say if you look around enough you can find some sorts way to run that line set. Would be a shame to spend close to 10k in leds and not be able to cool
It.
It.

Thanks for the constructive comment. I'll talk to him about replacing a brick or two instead of just drilling a hole. There's no windows unfortunately.

Its 100 outside right now and 94 in the garage. I'll fire up the lights soon and watch the temp after an hour or two during the hot part of the day. I'm thinking hiring a mason to replace the bricks is making the most sense

What size unit do you think you'll go with? You'll have some btu of heat from dehumidifiers too I'd imagine.

I'm thinking I'll get a 36000 BTU 3 ton unit. Looking at Mr Cools

alpine home air sells blueridge mini splits for a pretty good price, I'd honestly consider the 48k/4 ton mini split to give yourself a little headroom above the calculated btu needed. I'd imagine you'll be running a sealed room, you'll need a dehumidifier, 120-150 pints per day plus enough extra a/c to displace the heat from the dehumidifier..

A/c in the garage? that could only raise the home value right? Maybe install a mini-slit system and leave it when you move. You get less hassle and your friend gets an a/c unit in his rental or whatever.

Phoenix. I’m getting hot just thinking about that place during the summer. Yuck! It’s gonna be 108F this monday where i’m at in Norcal. I sort of know your pain.
I built, and had just rebuilt my buddies sealed setup a few yrs ago up in Payson. 6750W of light. I installed a 3ton mini split.
That’s up in Payson, and in a very insulated room. Down where you’re at is no joke during the summer months which i’m sure you know lol. But good thing you are just flowering in there and not needing lights on during the day. (Our day).
I’ve never ran one of those bigger portables, but the smaller ones suck. I would 1000% do a minisplit. 4ton, as someone also said, def safer but 3ton should work if insulated good.
Insulating garages for growroom can be a bit tricky. The ceiling and door need special attention. I usually build a wall in front of the garage door also when i build out garages for growrooms. Down there i’d probably build a 6” wall and fill with R21 lol

A small foyer at the entrance can save your cooling cost
Going in an out causes even more heat load

Really appreciate your insight as well as the rest of you guys. I'm planning on having the lights on from 10pm-10am so I think the 3 ton can handle it. The ceiling is insulated with r19 insulation from a previous owner with a few spots I need to refill and the garage doors have foam board insulation on them but theres plenty of space between the brick and the garage doors. I was planning to build a box around it like you said and fill it with some insulation. I looked at the 4 ton units but the outside unit is twice as big as a 3 ton and less low key for the neighbors but if you change your mind and think a 4 ton is necessary let me know, thanks.
Holy shit! I just have a little Frigidaire for when it’s needed. I hope this what you’re looking for a man good luck on your grow man

with these models of portable AC you need to hook a duct to outside, do you know this ?
otherwise i don't know how you will discharge calories
its either a outdoor unit that cool the freon, or a big duct that will blow the hot air outside (like this portable AC)
the second option ask for a even bigger hole in the wall
ducted AC's ae very inneficient, because they always exhaust some air of the room outside, sucking fresh hot air in the room
also all your co2 will be wasted, the burner will stay one 24/24 to keep proper co2 levels, heating the room more and more
like a crazy snake bitting his tail

It isn't the square footage that is at issue it is the heat load in the footage

Yeah I have been convinced that the portable was a terrible idea. I'm going with the 3 ton mini split. I was going to vent the portable into my attic but the whole thing was just stupid, there's no filter so thats some stinky hot air I'd be pushing out of my room.
