It's a really good secure feeling to know that you can fix your own shit. I always keep a few cylinders of R-410a on hand. I hate that whole John Deere situation with the right to repair garbage. You should be allowed to buy parts and fix your own tractor, especially when you have crops rotting in the fields.

you know big companys don't like it and I know their just being greedy at this point. now if it was for something that has to be done correctly or someone could die that isn't u then I see could see why. they should release info on parts and diagnosis for problems. U know why they don't wanna give us shit they just want money how I see it.

Yeah I used to be able to buy the refrigerant off amazon then they quit. I am glad I bought a bunch when it was on there, the price was really good too, my HVAC buddy said it was as cheap as the wholesale price they get it for at his work.

Equipment needed for a very basic install would be a vacuum pump, gauge manifold, hoses, 5/16" port adapter, probably an allen head wrench to release the charge after youve pulled the vacuum and let it sit overnite to make sure it's not leaking. A flare nut torque wrench and nylog is also something you will want.

May need a flaring tool in case the factory flares on the line set are damaged or just not perfect (I always make my own flares regardless).

If you want to really make sure there are no leaks you need a cylinder of nitrogen and a regulator. This allows you to pressure test the lineset (pushes fittings apart instead of pulling them together as with a vacuum).

You will need to run power and set a disconnect outside to run a whip from to the condenser unit. Will also need a properly rated cable that goes from the condenser to the evaporator (control and power for indoor unit) usually they require #14 wire but consult the installation manual.
Sooo there are few hiccups in this process my room obviously not up to code nor is the electrician work. So in order to get the permit I would need to tear everything down and have the city inspection team come look at it. Then buy the unit and have it installed. That would put me in a bigger cash crunch because Id have to pay for certified electrician to come re do it all and the room its self would have to be redone up to code.

Call a different AC guy to get a quote if that's the route u wanna go. I had an estimate for my building and they said 18.5k and the guy asked if I wanted to pull a permit or not. That was the price without a permit. (Was 4 units total)

I ended up going with a DIY mini split because I couldn't afford the installer price and didn't have the tools to do it. It's still a new install but so far so good. The unit could be a little more powerful and probably would have been if had gotten a name brand unit. It's struggling to keep up if I run all my lights on overdrive and I went with 6k btu per fixture.

It's all the same steps as installing a regular mini split for the most part except that the fittings are different. And then you don't have to run a nitrogen test or vacuum. It took me a good 6-8 hours to install, with running electric and all. If had done a regular mini split would have prob taken another 4 hours or so to do all the extra steps at the end. I also didn't void any warranty installing this unit as it's made for diy.

It basically comes down to if you want a warranty and have the tools. I was around for my other mini split to be installed and none of the rest of the steps skipped by doing diy are any harder than the initial install. Just requires tools and a bit more time.

Yea honestly probably will wait on the permits when I can pay to start all over and have pros do everything. I am looking at this point into buying the unit and searching for someone else to install to make sure its done right. The representative said here in California I have to have reclassify code agreement from the city before they could install only portables are allowed in the garage until its turned into something else.

Line sets can be about any length as long as the installer understands to add more gas. So you can put the outside unit by the house if that would help.

Dragonhouseterpz on IG does great work with mini splits in California. He would be a great guy to use if he is anywhere close to you. If he is not find someone who does a lot of garden HVAC work, call various hydro stores, some will have HVAC guys they recommend. Lots of HVAC techs into gardening, the ones that aren't are hard to work with as they don't understand our sizing requirements, and Ive found quite a few of them to be idiots. They will also understand local requirements and know the best way around them. There are still trap houses all over Cali with a yard full of units, you can't tell me they all got permits.

Def go with 6k btu per light, I chose a cheaper brand ,Mr. Cool, so I could install it myself. And if I run my lights on over drive it struggles to keep up when hot outside. Granted that's like an extra 900 watts total between my lights but it should keep up a lil better imo.

My point being a 1000 watt de light ran on overdrive needs every bit of 6k btu, atleast on off brand units.

I couldn't give in and get the mitsubishi Lol, so i got a bigger MrCool DIY unit I got the 36k BTU. The reviews didnt seem horrible and i dnt need the technician it says. I figured at 36k btu it would be ok since the mitsubishi I was looking to get was 24k.

I just installed the same unit a few weeks ago so far so good. If I was trying to over drive the my 6 1k de hps lights on a hot day I doubt it would keep up but it would most likely not have to dim below 100%. The install is not that bad, if your at all handy. You will prob need another person to help you run the line set and mount the head unit as it is a fairly big head unit.

As I understand there are also some brands that have pre-installed and pre-filled tubes.
So it is totally DIY.

I am not expert, as you might have noticed by the words I use.

My room has 6 gavita de 1k lights.

I'm at the end of flower so I have my temps at 74-75. When my lights were on 115% my temps were 78-80 range. I need to find a more accurate way to set the unit though. Atm I just have it set to 65 and when the lights are on 115% it was in the 78-80 range and when I turned the lights down to 100% it sets at 74-75.

I honestly haven't messed with the thermostat much but need to find the wire and make sure it's not in a spot getting hit with direct light or by a fan. The remote also has a follow me feature I wanna play with which I feel will be more accurate if I can find a place that's not in direct light that can get still get the ir signal out to the unit.

It's been working fine the way it is, and I've been super busy, is why I haven't messed with it much. I also have to buy a WiFi extender to get signal out in my building so I can set a schedule for the unit so I been dragging my feet messing with it. Im also about ready to throw some veg plants in there, as soon as current run is chopped, so I'll have more day time hours to explore and mess with temp settings. Since I run my lights at night right now, by the time I'm done gardening I'm ready for bed, lol.

Ok then I should be good reaching 75 degrees, those gavitas are very hot. I have 3 of cheaper brand 1000 wat de and one gavita de 1000 watt. With 3 running at 100, the thermo in the soil reads 80, the thermo up higher at the middle of wall reads 88. Plants look decent have grown good but want them cooler.

What do gavitas yield per light in perfect conditions i am thinking about getting more if i can cool the room down.

Well, to be honest I've never had perfect conditions, after I got my c02 hooked up at last spot my damn mini split there quit working so had to vent and couldn't run c02. In my last spot which was an 8x11 room with 2 4x8 tables and 4 gavitas I hit 9.5 lbs so almost 2.5 per light with no c02.

It's possible to hit 3+ lbs per light with the gavitas or similar de lights. Im hoping to do much better this run as I was able to spread my lights out a bit more to cover more canopy. 4 lights over 2 4x8 tables was a little too small of footprint for the lights I believe. Although this run was from seed so we shall see what happens. I got a mono crop vegging now and that will really show me what this room is capable of, plus I'm hoping to get c02 hooked up before flipping the next run to flower.
