What are the maintenance items for car air conditioning?

Car air conditioning maintenance items include: cleaning the condenser, inspecting the air intake filter, checking the refrigerant level, examining the connections of various components, and regularly starting the air conditioning compressor. When inspecting the air conditioning system, the car should be parked in a well-ventilated area. Car air conditioning is an air conditioning device installed in vehicles, and its functions are: 1. Cooling, heating, ventilating, and purifying the air inside the cabin; 2. Providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The car air conditioning system consists of a compressor, electronic control clutch, condenser, evaporator, expansion valve, liquid storage dryer, pipelines, condenser fan, vacuum solenoid valve, and idle speed controller.
I've been driving for over a decade and nothing annoys me more than AC problems. When the cooling is slow in summer or there's a musty smell, it's truly unbearable. The key is regular maintenance - I usually service it once a year. Mainly replacing the cabin air filter behind the glove box, which anyone can do themselves. It traps dust, and when clogged, the air quality suffers. Then there's cleaning the air ducts - last time I had a mechanic spray antibacterial cleaner inside, which eliminated the mildew smell. The condenser needs flushing too - that area behind the front grille gets clogged with bugs and leaves, affecting heat dissipation. Also need to check refrigerant levels and top up if low. Remember not to just use AC in summer - run the compressor in winter too to ventilate the system and prevent mold growth in the pipes.
