What could be wrong with your ac in your 93 Chevy z24 it blows perfectly it just wont get cold?
If the air conditioning pump in the 1993 Chevy Z24 blows perfectly, but won't get cold, it is possible that the Freon needs to be recharged in the air conditioning unit. This can usually be done for about $40 by the consumer.

What could be wrong if central heating and air conditioning when put on cool it blows hot air?
If you have a Heat pump, you must set the thermostat up for "heat pump". Then you must connect all the wires up according to the manual. If you do not have a heat pump, the wiring may be crossed or touching somewhere. Call a local heating and air conditioning company to trace out the problem.
