Upon first start up a/c blows cold and normal. But soon as you accelerate the heater kicks on and never blows cold again.

This really needs to be checked by an AC expert. AC diagnosis is really not a DIY thing. Someone has to analyze what the system is doing by watching pressures from the start. The system could have a restriction or numerous other possibilities.
