I'm not convinced by this product.

With the engine running and the air con set to LO.....the temperature of the air coming from the vents in my car, is about 2.5 deg C. Not 16 deg C as in the video.
How cold should the air be? :y
-
waste of time......
you need a set weight of gas in the car...
and given the price of those cans, money much better spent towards a vac and refil and do it properly.
abuot £50 plus vat normally
-
should be very low figures as per yours, not his which is very faulty beforehand.....and a bit better afterwards.

I heard somewhere that 3degC is about right.
But I'l go with Jimbob here - diy a/c top-up is a waste of time and money and may well cost you a bigger failure in the long run.
One of the reasons the system is vacuumed first is to extract the moisture from the system before replacing it with a measured volume (mine is 900g) of refrigerant gas. Residual moisture will react with the gas and form an acidic mist - which will eat away at the internals.
Nah - get it done proper, like! (There's a guy in Langley - near Slough - does a vac/gas for £40.)

Total agreement with all that :y :y :y :y
Guy in Swindon £39.99 for a vac/regas/system check... and he will NOT recharge if the vac process detects a leak.... I've watched him turn away customers who want a quick "top-up" just to sell the car.

I Googled "car aircon" and "slough" and found several. If you do the same thing Opti you'll probably find a few near you too.

Temp it should reach depends on the outside temp. Usually 4-8 degrees should be the scale, if it's far over 10 degrees there's some kind of a fault. Really cheap enough to have the system re-gassed, some 99 euros is a typical cost here in Finland. They willmeasure the correct amount of R134a and they will check that the system does not leak (or they are supposed to do that... >:( ) and they will check it's working and giving cold enough air to the cabin.

I would also echo everybodies advise about getting it done properly.
Plenty of specialist A/C guys around and you will get a proper job done.System should be drawn down to a vacuum to remove all moisture and old gas and then refilled with the correct weight of gas.
Looks a bit bizzare just shaking the can and reading off a gauge..then adding more.How does that give the correct gas weight.
On a very hot day with o/side temp over 30c I get the air temp in my car down to around 5c.If the best that can do is bring it down from 26c to 16c I wouldn,t waste my time or money.Would be cooler with the window open.
Snake oil me think.

Had my aircon regassed at a vauxhall dealer in Southampton cost £69. Told me they are not allowed to gas aircon if they detect a leak as gas is harmful.

The potential fine is £1000's & a gaol sentance I believe :-?
My local Vz charges £45 for a regas ......... I'm sure they'd try to find enough faults to bump up the price though ::) ::)

The DIY thingys as a CONJOB and not work a twopenny W**K! You are likely to cause more problems than you solve. Although mine is working correctly and satisfactorily for me I am not sure about the temperatures which have been stated but with Climate Control, as on mine, the lowest you can set it to is 17C and after that it mearly reads LO.
Reckon I will put my electronic temp probe into the vents to see just what it is. 2-3 seems to be far too low considering most fridges work at 5C and I would be happy with 10 - 14ish. Who wants to have it down to 2 or 3 and then have to wear a wooly jumper anyway? That would look really daft on a hot day :D ;D ;D ;D ;D ;D
-
The three Mantas run around 4 deg at the centre vents which in nice and cold :y

LOL one of the t4 vw campers we have here at the moment, air con actually mists the screen its so cold!!!
god knows what its putting out but was sat waiting at the arport for a party of people and just left it running for about 30mins, and had to clear the screen to drive off!!!
-
Presumably then the Climate Control model types are not able to achieve temperatures as low as the non climate control types because every car I have had , all with climate control have never got below 12C.
Why anyone would want to have frost on the inside of the screen therefore making it liable to a stress break beats common sense? Who wants frost inside the car :D only possibly an eskimo :o
-
had mine done the other week by a mobile guy.
after the necessary checks, weighted the bottle on some small scales.
on the invoice was details such as current temp (17c) and the temp at the vent (6c)
it didnt feel that cold at the time but last weekend when it was warm the air con done the job for the old dear with a hot flush i had to chaffeur to a wedding.

The air coming out of the vents needs to be considerably colder than the set temperature if you want it to achieve that temperature quickly..
So if it's 25C outside and you ask for 17C, the air will be at ~3C for quite some time trying to extract enough heat out of the air in the car to make it 17C. That's how all aircon and climate control systems work in cars, houses, offices..
As the air in the car approaches 17C, the air coming out of the vents will start to warm up to closer to the set point.
(Ditto for the reverse, if it's 5C outside and you ask for it to be 20C, expect the air coming out of the vents to be much hotter than 20C while it tries desperately to raise the temperature)

Yes . Spot on Aaron. I think... :y
