Air conditioning, is now a common feature on most vehicles, but most vehicles lose up to 15% of the refrigerant gas per year that is used to operate the system. This leakage usually occurs because the system is not used during the winter months, allowing the small O ring seals to dry out and causing a gradual deterioration in system performance. If this continues, eventually the system will not be able to operate at all.

Warning signs of a faulty system

It can be tricky to know exactly when your car’s air conditioning is deteriorating, leaving you hot and sweaty when summer rolls around. Here are our top warning signs of a faulty car air conditioning:

  • Insufficient cooling from vents
  • Unusual odours from vents
  • Noisy drive belts, compressor or blower motor
  • A rhythmic clicking noise from under the hood with the air conditioner or defroster on
  • An electric cooling fan that quickly cycles on and off
  • Windows that won’t defog when using the defroster
  • Water on the floor of the passenger compartment


To reduce the risk of deterioration, consider running your air conditioning during the winter months too, as this will help to maintain the system. This will help to keep the system well lubricated and leak tight.
