What are the maintenance items for a car's air conditioning system?

Car air conditioning system maintenance items: Check the air filter, check if the blower is functioning properly, check if the refrigerant is sufficient, and inspect and clean the condenser. Additional information on car air conditioning system maintenance is as follows: 1. The air conditioning system is generally equipped with a circulating ventilation filter and a refrigerant receiver-drier, which should be cleaned and disinfected promptly during maintenance. 2. The method of observing the inspection window can be used to determine if there is any refrigerant leakage. The condenser can be gently brushed with a soft brush or cleaned with running water. If using a high-pressure water gun for cleaning, adjust the water pressure appropriately to avoid damaging the condenser fins due to excessive pressure.
Before every drive, I check the air conditioning system to ensure safety and comfort. The most basic maintenance task is regularly replacing the cabin air filter, typically every six months or 10,000 kilometers, to prevent dust and mold buildup and avoid unpleasant odors. It's also important to frequently check the refrigerant level; insufficient refrigerant can make the air less cool, making summer heat unbearable. Additionally, remember to clean the condenser and evaporator, as oil or dust buildup can significantly reduce air conditioning efficiency. I make it a habit to inspect the compressor belt during seasonal changes, replacing it promptly if it's loose or worn to prevent belt breakage that could affect cooling. Don’t forget to clear the drain pipe to prevent stagnant water from causing mold and polluting the cabin air. Occasionally running the air conditioning in winter also helps protect rubber components from drying and cracking. These maintenance tasks don’t take much time but can extend the air conditioning system’s lifespan, ensuring a comfortable journey and avoiding mid-trip breakdowns.
As someone who enjoys tinkering with cars, I've found that the key to AC maintenance lies in the details. Start with the simplest part—the cabin air filter. Replace it every season; just buy one online and swap it yourself to save money and stay practical. Next, check the refrigerant pressure—top it up if it's low, otherwise cooling will be slow and fuel consumption will rise. Cleaning the condenser isn’t hard either—rinse off insect remains or debris when washing the car, and spray foam cleaner on the evaporator. Don’t forget the drive belt—listen for noise or check for wear, then adjust or replace it if loose. The condensate drain often clogs, so I use a small needle to clear it. In winter, run the AC for ten minutes after warming up the car to prevent system rust. These small steps add up to keep the AC blowing strong cold air, making driving more enjoyable while reducing the chance of unexpected breakdowns.
