Over here you can get by without aircon. Over there you end up poached in your own juices and have to be sucked out of the car by a professional waste disposal operator.

When a flagship £30k Skoda Karoq Edition has poorer A/C than a £14k car of the same brand then I think it's reasonable to question and criticise the poor aircon of the Karoq. Whatever country one lives in.

Oi, stop twisting the truth of the post - I pointed out that if a 10 year old Golf can knock out 4c in a matter of moments a new Karoq should at least equal it.

 

And if I like it cool in my motor that’s my business…………..

Our house is anything but a deep freeze.  I like a nice 21-22 deg C all winter.  However, this summer, in similar ambient temperatures, I've noticed that the output from the aircon in our 20 month old Karoq is anything but cold.  It's certainly not on par with that from my 5 year old Yeti or my previous 12 year old Golf.

There have been several points put forward as to why that is no longer the case with the modern WTLP (or whatever the term is) emissions standards, the change of refrigerant etc.

 

I believe that for EU countries a car aircon system should be able to chill the incoming air by 10°c, any more being a bonus, using the recirc function will speed things up.

 

A house AC system needs even less cooling as in general they are well insulated and dont become sweatboxes like cars in sunny weather unless you have one of the Grand Design type greenhouses that they claim are super insulated. Going into an enclosed area  and having the temp drop 10°c for a car or 5°c for a house is very refreshing.

 

Clearly the AC systems for tropical countries need a lot more oomph.

 

My Octavia 2 would chill 20°c air to 4°c, it would get to zero at lower ambient temperatures when I tested it but it would be the heater being used on those days, the Yeti system has exactly the same pump but brought it down to 7 or 8°c when I tested a couple of weeks ago although the outside temp may have been a little higher, the system had a full refrigerant charge verified by VCDS and my test manifold set. Those were evaporator readings from VCDS, the vent duct temps would be higher.

Don't know how we survived Death Valley without aircon.

I guess it depends when you were there.  The first time we were there was early October '99 and it would probably have been bearable; although I think the Mercury Grand Marquis rental barge did have A/C.   

The summer of 2019, it was 48 deg C and the A/C in the Nissan Rogue blew nice and cold.   We were glad of the aircon, even if the humidity was low.   

 

On the other hand, I once rode a motorcycle 1200 miles across I-70 in less than 24 hours in temperatures of 40 + deg F and humidity in the high 90's % and that was anything but pleasant. 

Car just back from the dealers and apparently my air con is working fine, though not as well,as I expect my 5 year old Ford would pump out very cold air, I am disappointed but apparently it's to do with the new refrigerants they are not as effective as the old ones, more progress

Skoda must surely fit better / more efficient systems on vehicles destined for warmer climes, such as Spain or Italy?

Thing is though, people in hot countries don’t try to turn their cars into mobile fridges as some here do at the first sign of the sun.

I’ve kept the ac on auto and temp set to 19-20°C 24/7 365 in the last 4 Skoda cars I’ve had and never felt too hot or come to that too cold in any of them, come hail rain or shine.

No the refrigerant is the latest spec and used in all markets, it not that it doesn't work, it just not as cold as my 5 year old Ford was.

My 2018 Karoq Edition aircon has never got cold enough for me. Using the Carista app I was able to change the car's internal aircon setting to "for hotter countries" which "may" have cooled the interior down a bit more or I could have imagined it. When I hired a 2020 Skoda Kamiq last year the aircon on that was absolutely freezing as soon as I started up the ignition and stayed freezing throughout the journey. So it can't be EU restrictions on the coldness.I don't understand why the Kamiq aircon is so lukewarm in comparison. My 3-year service is due next month so I'll have the dealer service the aircon and check it over for me. But I've a feeling they will say "it's all working within specification".

Hi FabFabFabia,

 

So was that Carista tweak worth doing do you think? Based on your long term observations).  I expect your answer is "no" if you are going to get them to check the aircon.  In my 2019 Karoq I have the intensity of the fan set to "low" in the Amudsen menus (as I prefer a quiet fan wherever possible) and I found that when it was 23C outside a week or two back. I started my journey (after opening all the windows for a few seconds prior to getting into the car and then starting the engine and closing the windows) that I was very unimpressed (Climatronic set to 20C) as the air was not that cold coming out of the vents.  But ....... in truth, within 10 or so minutes of driving (from a cold engine start) the AC had obviously cranked itself up as the cabin temperature seemed to be fairly comfortable (and I would guesstimate around the set point of 20C).  Maybe the AC is given a lower priority and allowed to consume less energy when the car first starts and then once a little warmed up maybe it cranks itself up.

 

I also had the feeling that as soon as the sun shone directly into the windscreen I could feel the heat quite intensely but within a few minutes the AC had definately cranked up because my poor bare legs (shorts) were bloomin freezing. I had to crank it back up to 21.5C :-)

 

For me all I want is to set 21C or similar and the car to be "about 21C inside "most of the time". If it is I'm happy and Climatronic is doing its thing.  Not sure it works as well at doing that as my 10yo Tiguan did (with the old gas and a differnt logic in the software / sensors for climatronic no doubt) so I agree that the 10yo cars are more effective at cooling (and contributing more than the newer cars at helping to further destroy the environment in the process).

 

Problem is that all of my observations on this are very subjective and just "feelings" rather than hard fast data :-)

 

Cheers,

Paul

Well today it was 30C here in sunny Devon and I've changed my mind - the Climate control is Cr*p!  Quite prepared to admit I was very wrong!

 

Hopefully this might help someone ......   What I did discover is that if you close the rear centre vent and pop the recurculate on it makes the world of difference (only applicable if you only have front seat passengers so not useful in many cases).  It was a real revalation.  All those who have only front seat occupants might want to try that as it was night and day.  Having full climate control the system could have been designed to mean that you should not need to do that (in theory) but the car does not take account of the fact that no-one is on the back seats and close/divert that vent exit. The manual intervention might be a real help to all those suffering and who want a good blast of nice cold air from the get-go.

 

Good luck everyone. We might need all the help possible this week :-)

"pop the recurculate on it"

 

this always makes a world of difference, in every car I've driven - it cools the air much faster

 

don't know why this isn't on by default when setting low AC temp (while outside temp is very high), and why it turns off auto AC in karoq when enabled..

Edited 19 July, 20214 yr by Fux

Because you should only do it for a short time to ensure the air in the car stays fresh.

use recirculate to boost the ability of the a/c initially then for short periods thereafter as needed, or to stop fumes coming in when encountered

What do you mean by air staying fresh when air re circulation is turned on?

Doesnt that air get filtered as well/go thru the whole AC (just the same as drawing the air from outside) ? I mean it should, otherwise it wouldn't stay cold for very long

 

Btw doesn't the "Air Care" AC functionality cut off drawing air from the outside? Once you turn that on, it also stops drawing air from outside

 

 

On the subject…yes..a/c isnt very quick with cooling but once you get moving it really maintains  pleasant temp inside the car. Thats my experience.

Recirculate means that next to no fresh (oxygen rich) air enters the cabin. After some time the levels of Oxygen will reduce and the levels of Carbon Dioxide will increase.  This can lead to fatigue (amongst other things) so the recommendation is to only recirculate as the exception rather than the rule and for as short a time as possible generally.  i.e.  some minutes to get a quick cooling affect, a minute or so if you are in a smelly environment or stuck in polluting traffic etc. The AC is generally always meant to be on with Recirculate too as the moisture levels can build up and cause interior fogging.  I think the absolute Maximum is meant to be 30 minutes which is why the recirculate automatically turns off after a certain period.

 

Hope that helps.

Paul

It's hideous.

 

Mrs Phutters is from Tennessee, so she's used to it. I'm not from Tennessee, so the summers of the few years we lived there were a trifle uncomfortable. The sweat pours off you even when you're completely inert, and it just doesn't evaporate.

 

The first car we had there - a 1981 Honda Accord - didn't have air conditioning. We drove across the middle of rural Tennessee to the middle of rural Georgia and back to get a bag of onions one summer. I could explain, but it really isn't worth it.

 

The temperature was in the upper nineties and the humidity just as bad. Of course we had all the windows and the sunroof open, but it really didn't help.

 

If I remember correctly we collected most of the population of large and ferocious-looking insects in the back seat en route, not all of them dead.

Humidity's the killer, metaphorically, most of the time.  My first trip to Australia - Perth, WA - was in early 1988.  We walked out of the cool air-conditioned terminal at 6.45 AM and as the doors swooshed open we were hit by a wall of heat, over 80 degrees F,  28 C. Before 7 AM.  No time to acclimatise, just bang!  They were in a run of something like 30 days with temperatures over 30 C.  But it was very dry, so while I won't say "comfortable" it was eventually bearable.  After six weeks of that we went to Bangkok for a week, and while the temperature was around 7 deg C.  lower, the humidity was much higher and it was definitely very uncomfortable. 

 

There's an offshore wind called the Fremantle Doctor that cools the Perth area by several degrees, when it doesn't blow the temperature hits the 40s daily.  It doesn't make the international weather news like Sydney does.

Already mentioned, but when it's hot, make sure the AC profile is set to strong/Intensive not light/medium.

Not sure on the Karoq, but on the octavia you either go to settings on the audio system screen or press and hold the lower central button on the climatronic with the word setup or menu on it.
