Why does my AC make a whistling noise?
In most cases, a high-pitched whistling sound means that your air conditioner isn’t getting enough airflow through the return vents and ductwork: the ones that pull air from your home to the air conditioning evaporator coils to cool it. Your air conditioner has to work harder to pull enough air through the system.

A refrigerant leak is unique in the sense that refrigerant evaporates instantly into a gas once it isn’t under the pressure of your closed loop A/C system. A/C systems are sealed and therefore don’t require refrigerant top-off’s. If the refrigerant level is low then there is a leak that needs to be addressed.

Why is my car refrigerator blowing hot air?
Both systems include a compressor, condenser, evaporator, and receiver/drier. Your refrigerator, however, isn’t subjected to the extremes of heat and vibration that go on under a car hood. The system in your car has several failure points—O-rings, seals, rubberized lines—all of which can crack, dry out, and shrink, leading to a loss of refrigerant.
