Most drivers only think about their car’s air conditioning when the sun’s out and the cabin starts heating up. But your vehicle’s air con does much more than just keep you cool on warm days. It also plays a key role in demisting windows and filtering the air you breathe.
Like any part of your vehicle, your air conditioning system needs regular maintenance to stay in top condition. In this blog, we explain why air con servicing is important, and what you can expect when your car goes in for one.
Why You Should Service Your Car’s Air Conditioning
- Maintain Cooling Performance
Over time, your air con system can lose refrigerant gas – the substance that keeps the air cold. Without it, the system becomes less effective, and on hot days you’ll notice it struggles to cool the cabin. A service ensures it stays charged and performs efficiently.
- Keep the Cabin Air Clean
Your air con filters trap dust, pollen, and other airborne particles. Without regular servicing, these filters can become clogged, reducing airflow and spreading unpleasant smells or allergens through the car. For drivers with hay fever or respiratory conditions, this can be especially uncomfortable.
- Prevent Unpleasant Smells
Moisture builds up in the system and, if not cleaned, creates the perfect breeding ground for mould and bacteria. This is often the cause of that musty smell when the air con is first turned on. A proper clean during a service helps keep your car smelling fresh.
- Avoid Costly Repairs
Small problems can quickly develop into bigger, more expensive issues if ignored. Regular servicing helps spot faults early, like worn-out seals or minor leaks, before they turn into major repairs.
- Improve Fuel Efficiency
A struggling air con system has to work harder, which puts more strain on your engine and uses more fuel. Keeping it serviced helps your car run more efficiently and reduces unnecessary fuel use.
What Happens During a Vehicle Air Con Service?
A typical air conditioning service for a vehicle includes:
✅ System Leak Test
A leak test is carried out to make sure the refrigerant isn’t escaping from hoses, seals or the compressor. If a leak is found, it needs to be repaired before the system can be safely recharged.
✅ Refrigerant Check & Re-Gas
The technician checks the refrigerant gas level and, if low, removes the old gas and refills it to the correct level. This process is called “re-gassing” and is essential to maintain cooling performance.
✅ Cabin Filter Inspection & Replacement
The pollen or cabin filter is checked and replaced if dirty or blocked. This helps maintain air quality and improves airflow through the system.
✅ Bacterial Clean
An antibacterial treatment is sprayed through the vents to kill off any bacteria, fungi or mould living in the system. This removes odours and keeps the air fresh.
✅ Pressure & Temperature Checks
The system is tested to ensure it’s reaching the correct temperature and operating at the right pressure, confirming everything is working as it should.
Most manufacturers recommend servicing your vehicle’s air conditioning system every 18 to 24 months. However, if you use it frequently, or notice a loss of performance, strange smells, or noisy operation, it may be worth having it checked sooner.
Vehicle air conditioning isn’t just a summer luxury – it’s an essential system that improves comfort, safety, and air quality all year round. Regular servicing helps prevent problems, saves you money in the long run, and keeps your car cool and comfortable whenever you need it.
If you haven’t had your air con checked in the last two years, now’s the perfect time to book a service.
