Do you think I can get by with a 3 ton mini split instead of a 4 ton since I'll just be running the lights from 10pm to 10am? The garage has R19 insulation in the ceiling and soon I will build a box around the garage doors and fill with insulation but already its 94F in there when its 100F outside so I think its pretty well insulated. Thanks a lot
I think you have your heart set on that 3 ton
Yeah I guess I was set on the 3 ton but I think the 4 ton can work if I can run a 50 ft lineset and put it in the backyard. There's two spots where I can place the mini split. One would be on the wall facing the street and the outside unit would just sit on the other side of the same wall. That's where I would prefer the 3 ton because its half the size of the 4 ton and more lowkey for neighbors.I think you have your heart set on that 3 ton
If you do you could add lights till you determine maximum load it will take
But I think you are going to be short with all the other equipment in the room
I've never said man I have too good of cooling but everyone has been in the position of "shit Im short"
Usually resulting in trying to nurse this one run home
I have a 2 ton mini for a sealed bloom room that runs at about 8000 watts in a basement that typically would stay in the 60's year round. It's barely enough, my temps get into the upper 80's, the only equipment inside the room is a pretty efficient dehumidifier, fans, and lights. I'd honestly be scared of a 3 ton in your climate.. I'd go with the 4..
Only prob with running a 50’ lineset is you’ll need more refrigerant. Most likely a tech to do that.
They have small cans of 410 you can buy, He could use a kitchen scale to add in whatever additional is required, or he could just run it the way it is and have a hair less efficiency..
I can tell from his posts, from the fact he started out wanting/hoping that the portable would work, and that he mentioned the diy mrcool, that he’s never installed a minisplit. Firing up your first minisplit AND adding refrigerant is prob a no go. I would imagine.
You’re probably right..
You are correct.
Thanks man I appreciate the input
They sell a coupler kit to connect the pre-charged lines sets together, supposedly without additional refrigerant, if you need a run longer than the 25'.
Haha nah just a wife whose not thrilled with growing weed at her new house. I found a spot where the roof meets the wall and I can feed the lineset so she chilled out and we are good to go. I'm just going with the 3 ton. I ran a 5 light bloom room during the daytime in a less insulated space with an 18,000 btu window ac and it was ok. So I double the lights, double the ac btu and upgrade from window to minsplit and have a more insulated space.. im just gonna buy the mr cool 3 ton and get started.
Hire a licensed contractor. It will be worth it for warranty purposes and if anything goes wrong and you need a technician to come out in an emergency.
Thanks for the tip. I'll call around and see what the what they'd charge.
Good luck mate
