When to Add Refrigerant to the Air Conditioning?

[DiTheo]

There is no fixed cycle for adding refrigerant to a car's air conditioning system. The need for replenishment is primarily determined by the cooling performance of the air conditioning. If you notice poor cooling efficiency during use, an inspection should be conducted, as the issue is often caused by refrigerant leakage. The following are the functions of the air conditioning system: 1. Achieve cooling effects through the continuous transformation and circulation of refrigerant. 2. Draw in fresh outside air to ventilate and refresh the cabin air, preventing windshield fogging. 3. Utilize engine coolant, waste heat, or heat generated by a burner as a heat source. This heat is then transferred through the heater and blown into the cabin by the blower to raise the temperature and achieve heating effects. 4. Remove dust, odors, smoke, and toxic gases from the cabin air, keeping it fresh. It also humidifies the cabin air, increasing its relative humidity.
