How do I properly maintain the air conditioning system in an Audi A3?

I recently bought a 2019 Audi A3 and I want to make sure I am taking good care of it. How often should I check the air conditioning system and what maintenance should be done to keep it running smoothly?

First and foremost, you should regularly check your AC system's cabin air filter every 20,000 miles or more frequently if you live in a dusty area. It's easy to access and replacing it is usually a quick and inexpensive fix.

Another important maintenance task is to have your AC system's refrigerant checked for leaks and recharged when necessary. The refrigerant is what keeps your car's interior cool and comfortable, and leaks can compromise its performance.

To avoid musty and unpleasant smells coming from your AC system, consider using a disinfectant spray specifically designed for car AC systems. Simply spray it into the cabin air intake, which is usually located near the dashboard, to eliminate any bacteria and foul odors.
