What's up doc?

Ok, I like the car cool (not cold) and rarely use the heater, The air con comes on to cool the car but sometimes fails to keep cooling once it's got there initially. But now the weather's changed I've noticed the heater doesn't exactly push out much heat!!!
Heater matrix?
Climate control?
something else?
ideas please

Re-gas ???

gas pressure seems OK. In the hot weather the climate control blows cold from start but once it reaches temperature it's like it won't re-engage the compressor. I'm not even sure if that's connected to the poor heat output when I turn the temperature up, the fan blows, but the air is not warm enough to clear the screen. I'm fairly sure it's not the matrix leaking as the carpets are dry so my next thought is some sort of airlock between the engine and the matrix.
