How come the air conditioning doesn't blow cold air until the car is moving?

Answer by  benjiross (993)

The car has a fan to blow the air and a compressor that cools the air. The fan is connected to the battery and can be turned on. The compressor can come on only when the engine is running. hence the cold air is blown only when the engine is running.

It takes some time for the compressor to get up to full pressure and for all the duct work to cool down. Even when those first bursts of cold air start hurtling toward you, the ducting warms the air down. Only after everything is cool do you get cold air.

Your belt is probably loose, Check you belt tensioner and belt condition. Replacing a belt can be tricky, and would be good to be done by a state licensed professional.

Pressing on the gas pedal while the car is in neutral should speed up the process too - you don't technically need to actually be moving.
