How often does the air conditioner need fluorine?

Is the power line design of indoor air conditioner too short?

When the air conditioner is heating, why does the air outlet of the indoor unit smell plastic?

Why can't the air conditioner start immediately after it's shut down?

When installing the air conditioner, if it is necessary to adjust the circuit and power supply, why should we ask a professional electrician to operate it?

In heating mode, why is there no wind when it is just started?
