How cold is your a/c blowing?
 

Starting to warm up here in Vancouver, BC. Finally used A/C for the first these last couple of weeks. Even with the A/C set on "low" setting, it's only blowing cool air, barely enough to keep me cool when it's super hot. My RSX used to blow ice cold at the lowest setting. It's definitely working, because if I turn it off, it becomes warm/hot air, I just thought it should be colder than this on the lowest setting...

July has been hot in south TX (100 plus everyday) and mine blows ice cold on lowest setting.

Quit your bitching about the heat in Canada -The South

My A/C is blowing cold air, I can feel my fingers get frostbite if exposed for prolonged period of time..

When my auto A/C is on full, it is uber cold. I have to set my interior temp to about 72 or I freeze (unless it is above 95 degrees out which is rare here). And that is with me only using the drivers side vents.

I would get that checked out..

Ok thanks, that's what I figured, just wanted to check with others before I brought it in.

I would say there's a problem with your a/c. Here in Arizona on the hottest day yet it's not very long after I have my a/c on that I have never had to run the fan speed above #2.

Agreed.. Low 90's here with high humidity.. AC works great and gets cold instantly..
Which is a good thing with raven

Even with it set at 24 Celcius for both zones, it's blowing really cold. It's currently in the 30's in Ontario with ridiculous humidity. Some days it's "Feels like 40C". Even so, the air coming out is dry and very cold. I'd say you have a problem.

If its just starting to warm up outside... Then your fine..
The hotter it gets outside, the more efficient the AC becomes..

Mine isn't that cold either. I can run mine on max with the recirc on for hours and the cabin never gets cold - just comfortable.

I thought it was just a weak AC system to save weight and fuel, but after reading some posts I think I might take it in and get it looked at. I'm also near Vancouver.

Mine is very cold, thankfully... 98-104 degree days!

here in New Jersey we have been having some humid days in the 90's, i have mine on LO at full blast and it just keeps me cool. compared to my old 2005 acura tsx this ac is decent but my tsx ac was amazing. but i am also a big guy and am always hot.

Unfortunately you don't know how heat pumps work, and this is very false.

There is no need to get into a huge discussion about the physics of it, but it's safe to say that if it's less than 35 Celcius outside, and his A/C not blowing very cold air, there is a problem.

Its pretty cold, not that cold but an okay A/C unit in the car.

Ive seen worse...ever been in a Diablo?

Thats not how an HVAC system works buddy in a simple sense, the hotter outside it becomes the less efficient it becomes, it becomes harder for the condenser to transfer the heat of the cabin into the outside environment. The air coming out of the vents should be at minimum 20 degrees cooler than the outside air if running at maximum setting.

My AC unit blows colder than any other car I've had, so if yours does not seem cold, I'd check it out.

Actually I do know how they work.. Poor choice of words on my part.. My point was that you "feel" the temp difference easier when the ambient temps are higher outside. Without going into too much detail..
Like running the AC on a cold day.. You might not realize how cold the AC is actually blowing.. Not to get too complicated.. The OP did say it was just warming up outside.. As in not too warm yet..

My point was that the temp difference is more noticeable when its hot outside.. My bad using the word efficient..

Depending upon what you're comparing, it might feel warm. R134a is much less efficient than R12; pretty much all cars I've driven post-'94 (when R134a became mandatory) only blow cool when moving. At a stop, the exchanger can't reject the heat.

Having said that, IMO the system in these cars works pretty well.

I rarely run the A/C I discovered if you turn on the air, blow it on the windows, have it set to circulate in the car, it actually cools very well inside the car in 90 degree weather, with no power loss. :P

does it blow colder when u start driving?

turn car on, put AC on, pop hood and check the radiator fans. One of them has to be working. If none working, there is a chance that a fuse blew.
I had this issue after heavy rainfall in Toronto.

Edit: alternatively u can just put a switch to have both fans blowing all the time. Should make it better during summer.

Once you put the air flow onto windows it automatically turns AC on for us (without the physical light being on). Or so i was told by a mechanic at the dealer.

What? I can't get mine to blow cold at all without the A/C on, if I turn off the A/C and leave the fans running it becomes unbearably hot after about 2 minutes unless it's under 75 outside. Do you mean you put it on "defrost"? Because that does run the A/C system.

What do you mean by "put the air flow onto windows"? If you mean the defrost setting then yes, it does turn on the A/C pump to dry out the air and reduce humidity in the car. Other than that setting you tell the A/C when to go on and off.

correct kind sir

mines pretty cold. unless I'm at a stop then its coldish...but this was discussed in another thread. It's colder when there is more airflow. If yours isn't cold at all I would def get that looked at

I only turn the AC on when driving over 4000 rpm and not accelerating, the A/C system running makes me lose too much power and doesn't blow very cold unless I'm in the power band.

If you had aftermarket pulleys, say like Tomioka Racing Pulleys, would the amount of power lost from the A/C compressor decrease?

Shouldn't unless they were under driven.

Yeah, I mean the defrost... I guess that makes sense considering it does remove the humidity from my car... Hmm... I wonder if it is any more or less efficient than running straight A/C? If I run the A/C it gets cold... take it in and get it checked since it is/should be under warranty. If not, track the leak down and get a R-132a refrigerant (assuming that is what the FR-S/BRZ takes). Pretty easy to add to a car.

I started a thread on this at the beginning of the year and everyone, including me, said their a/c blew "hot" air.

i have not run my ac.... haha windows down and it turned to the cold side is good enough for me!

Me too, but my windows go up once I pass 50mph.

My AC works like a champ. It blows frosty cold even on the hottest humid day. I usually run it on low setting since it blows so cold that it freezes my arms. I use recycle setting most of time. That might help with the air getting so cold. Works like a freezer.

AC isn't very good. However, I have a koyo radiator, intercooler, and an oil cooler up there, so it the airflow the condenser gets is quite reduced. It works reasonably well, but I wouldn't say great.

I'd have to I'm not 100% impressed with my ac. Not ice cold but cool enough I guess. Seems like other cars are a bit colder. Next time I'm at the dealer I might bring up the issue. Has anyone actually measured the air temp coming out of the vents. I've done a few ac rebuilds and if I remember correctly 50F is really good goal to shoot for.

I have 3M Crystalline 70% installed all around. It helped the AC a LOT!! Before, I always switch it to 3, now even 1 is enough. So maybe instead of trying to get the AC to work better, help it do what it's doing now.

Note: Crystalline tint is expensive, but in my experience I've had it for 2 weeks and it already paid for itself. Earlier today, I tracked at Willow Springs and 103F+ sucks, but it's cool in my car, even with AC off.

I have noticed that mine is not very cool if I am sitting. Once I am moving it's fine. It combats Alabama summer heat which says something about a car's A/C.

I found that putting it on the defrost setting for a few minutes then using the front ac vents yeilds much cooler air for longer duration.

^true that the windscreen defrost blower is great

Why does this car blow hot air when I have the air off?
