As the weather warms up, many drivers discover their air conditioning is not as cold as it should be. This is a common issue in West Malling and Maidstone, especially if the system has not been used much over winter. At King Street Motor Services, we can diagnose and service air con systems so you are ready for spring and summer travel.

Common reasons air con stops blowing cold

  • Low refrigerant: Often due to natural loss over time or a small leak.

  • Blocked cabin filter: Reduces airflow and can make the system feel weak.

  • Faulty compressor or sensor: Can stop the system working properly.

  • Condensation and bacteria: Can cause smells and poor performance.

What you can do before booking in

  • Run the air con for 10 minutes and see if the temperature changes.

  • Check if airflow is strong, weak airflow often points to a cabin filter issue.

  • If you notice a musty smell, the system may need cleaning.

FAQs:
