It depends on the type of AC you have. Window AC units typically don't require much maintenance, though it's a good idea to clean the filters every few months. Central air conditioning systems require more maintenance, including regular filter changes and tune-ups. It's also important to keep the unit clear of debris and obstructions, and to make sure that the drainage system is working properly.
You should do maintenance for your AC annually. It's important to schedule a tune-up with a qualified technician to clean the system and check for any potential problems. Regular maintenance can help prolong the life of your AC and ensure efficient performance.
