And where? If so I'd like to check and clean it

Later Mitsus (380 & Lancer) have pollen filters that filter the air from outside, whether you are using fresh, hot or cold.

Third gens don't have filters.

380 does not have a pollen filter....

No? I stand corrected.

Ok so no filter. Aside from getting gas checked/refilled any other ways to boost AC performance? It's a bit weak. It'll still cool the cabin fine but on a 30c day i'll have it set to 18c and it still takes a few minutes to drop the temperature to 'not sweaty'. It doesn't actually get to 18c even though the computer thinks it does and lowers the fan speed, if I put it back up to say 22c after being on 18 for half an hour, it'll think "oh so you want the heater on then...."

I've read before that over years of driving the air conditioning condenser gets dirty/clogged and a way to get the A/C running cooler is having that cleaning

No a/c is going to cool a hot car instantly.

Park in the shade.
Have a couple of windows down a few cm.
Get window tint.
Run the A/C on manual. Or set it on 22 degrees and don't change it.
Check A/C belt is tight.

There are some gases better as refrigerant than the standard stuff - check Hychill.

My TJ will get a shot of that soon.

Max can you get back to us with how the hychill gas performs and the cost of of the regas?

Hy chill Is apparently very flamable, would not want this to be an Issue in an accident.

Had some HR12 put in my TP A/C years ago, less tha $100. Freezing!

Yes, HR12 is a hydrocarbon, much like the liquid in a cigarette lighter.
Could be an issue in a front end accident.
Then again, most of us carry large quantities of flammable hydrocarbons around all the time, without concern. (= petrol)

I get these sorts of comments a lot, but the reality is there are plenty of cars that can and do chill it near instantly. Old work hiace van had f'ing freezing A/C. No matter how hot it was, if you started the car and had it on max cooling you couldn't stand it after a minute and had to turn the temperature up. Same with sisters yaris. Thus if the same type of car can't do that, then the A/C is not operating at its potential
Now obviously different cars have different A/C units. From what i've read though these cars are supposed to have great A/C but I wouldn't describe mine as 'great'. I can keep it on 17c/maximum for ages, and thats just not good enough

... if I put it back up to say 22c after being on 18 for half an hour, it'll think "oh so you want the heater on then...."

If it's putting the heater on to get back up to 22c, then either the temperature at the sensor is below 22c or the CC controller thinks it is. This does not indicate poor cooling, if anything the reverse! I'd see if you can find an accurate thermometer and take a reading at or very near the sensor (on the TJII push button CC it's the little grill beside the temp control dial, not sure where it is on other models). Then set the temperature to something reasonable like 21c or 22c and see if the car is able to maintain it.

Other than this, a Magna has a much bigger internal volume than a Yaris (you could just about park one inside my wagon!) so the heating and cooling will always be working harder. Vans also tend to have much more vertical glass rather than the raked solar collectors the Magna has, so they tend not to get as hot inside in the summer (they are also usually white... could be a factor?). I find that with a bit of sensible heat management (such as parking in the shade if possible, cracking the windows, opening the windows fully with fan on high and fresh to blow out the hot air, then windows up and air on recirc for rapid cooling) the Magna wagon is as cool inside as any other car I've been in. If you are doing all this and you're still not happy, get it checked and serviced. AC places will check the cold air temp at the grilles, not sure what it should be but I'd guess fridge temperature, ie. 5c or something like that.

I checked air vent temps (middle vent) with a temperature probe. Using low fan speed but maximum cooling, it was somewhere around 2c. It cools fine when its been parked underground, but if its been in the sun it requires quite a while to cool down. I know what 24c feels like as thats very comfortable in my home, but in the car 24c is worthless, the max i'll set the CC to is 22.5c when its night time, during the day its on 18-19c

On a hot day the interior of a car can exceed 50 degrees. Takes a while to pull that down.
24 degrees in a car in full sunlight doesn't feel very cool because you are still getting direct sunlight on your upper body through the glass.

In short . . . .

BRO, YOU NEED TINT!

I have factory tint. But you can't tint the windscreen so.....

In any case it's not great. As I said i've been in other cars where the temperature just plummets. At the very least the air coming out of the vents should be so cold that I can't keep my hand there for more than 10 seconds. That's not the case, I can hold it there indefinitely on maximum. Does it feel cold? yes, does my hand turn blue? no
No matter how big or small the cabin in, the air coming out should be noticeably very cold

Well, you have exhausted our collective but inadequate knowledge.
Best go see an A/C expert and voice your complaints.

Sounds like the temperature sensor is giving a lower reading than it should.

that's not going to work. hychill cannot provide anymore capacity than a evaporator coil can produce.

id be checking that all air vents are free from blockages, has your refrigerant ever been replaced as you may have a partially blocked/restricted drier.

have a look at that and then if its still not ok let me know as you may need to look into insulating your suction lines as it may be picking up too much heat sending your superheat sky high. you may also want to check your condenser is free from bugs, tar, debris etc.

No idea what you mean by this, but I'm not going to argue with you.

I should have worded it better- an evaporator coil cannot cool more than its rated capacity.

an evaporator coil cannot provide more cooling capacity by simply changing refrigerant. each coil and TX valve is specifically designed for certain refrigerants amongst other things.

Not arguing! But I see your logic now.
