My ac/heat only cools/warms when I am pressing on the gas?

What is your question?

For example, when I am stopped at a light, the A/C will start blowing warm air and in Arizona in hte summer, it gets to hot in that short amount of time. I get it recharged every year but this does not fix the issue. Is this a defect in the Sprecta's? Is this something that can be fixed?
