As summer arrives, it’s hard to miss the annual reminders about air conditioning servicing and recharging.

There’s certainly a place for routine maintenance, but one thing that often surprises people is that air conditioning faults don’t always have the solution they expect.

This Discovery 5 is a good example. The system wasn’t short of refrigerant for no reason. The condenser had developed a leak, allowing the refrigerant to escape and preventing the air conditioning from performing as it should. Before the system could be recharged, the underlying fault first had to be repaired.

It’s a useful reminder that air conditioning is exactly that: a system. The refrigerant, compressor, condenser, expansion valve, sensors and control modules all rely on one another to do their job. When one part isn’t performing as intended, the symptom is usually the same. The air from the vents simply isn’t cold anymore.

Sometimes a recharge is the right answer. Sometimes a repair comes first. Understanding the difference is why diagnosis remains such an important part of modern vehicle repair.
