With the consistently hot and humid weather in Bangladesh, a properly functioning car air conditioning (AC) system is crucial for comfort. Many car owners here face issues like weak cooling, strange smells, or complete AC failure. What are the most important preventative maintenance steps car owners can take to prolong the life and efficiency of their vehicle's AC system in our climate? I'm looking for practical, actionable advice on things like how often to check refrigerant levels, cleaning condenser coils and cabin filters, identifying early signs of common AC problems, and whether regular professional servicing is truly necessary. Are there specific components that are more prone to failure in hot and humid conditions, and what can be done to protect them?

Clean the cabin filter every 3–6 months, check refrigerant yearly, and keep the condenser dirt-free. Run the AC weekly, even in winter, to keep seals lubricated. In hot, humid climates like Bangladesh, regular servicing is key—especially for checking leaks, compressor health, and electrical connections.
