What is the best way to maintain the air conditioning system in my Vauxhall Zafira Life?

I've noticed my car's air conditioning system isn't cooling as well as it used to. How can I keep it in top condition?

Regularly check and replace the air filters to ensure proper airflow.

Run the air conditioning system for at least 10 minutes every week, even in winter.

Use an air conditioning cleaning spray to get rid of any bacteria or mold buildup.

If the air isn't cold enough, have a certified mechanic check the coolant levels.
