Climate control?
 

Right guys, I've just got my asx 4 I'm sure a lot of you will know the answe to this one, before I bought my car they put a new a/c unit behind the dash, now I've had it a week I tried the ac all works fine, but when I put it on hot which at its highest is stated as 27degrees on the dial it only comes out slightly warm, it was 22 degrees today and was only coming out at 30 degrees, is this due to climate control or do I have a problem with my heater matrix, thermostat? And if I press the a/c button it gets colder even when still on the hottest setting, where as my last car didn't have climate control and on hot setting which was stated as 30degrees, it came out at like 45/50 degrees, I just need to know weather to take my car back to get it fixed on warranty, before I notice the problem in the winter and no longer have warranty,???? Cheers guys
