Car Air Conditioning: Everything You Need to Know

When most people think about their vehicle’s air conditioning system, they only think about it when the weather gets hot. However, your car’s A/C system is designed to be used all year round, not just during the summer months.

One of the most useful features of modern air conditioning systems is the recirculation function. During very hot weather, recirculation helps cool the cabin more quickly by reusing already cooled air. In winter, it can also help clear misted windows faster when used alongside the air conditioning system.

To keep your A/C working efficiently, regular maintenance is essential. Pollen filter replacements and air conditioning de-bug (anti-bacterial) treatments help improve the air quality inside your vehicle, removing bacteria, mould, and unpleasant odours from the ventilation system.

Manufacturers generally recommend an air conditioning service every two years to maintain maximum performance. This is because modern A/C systems naturally lose around 10–15% of their refrigerant each year. In fact, vehicles that rarely use their air conditioning can sometimes lose refrigerant more quickly, as seals can dry out and develop small leaks.

Common signs that your air conditioning may need servicing include:

✔ Taking longer to produce cold air in warm weather

✔ A hissing noise from behind the dashboard

✔ A musty smell when the vehicle starts

✔ Excessive window fogging during cold or damp weather

Most modern vehicles use R1234yf refrigerant, while slightly older vehicles use R134a refrigerant. At R & J Car Services, we are equipped to service both systems.

If your air conditioning system stops working altogether, we first carry out essential checks including compressor operation, system pressure, and climate control functionality. If no pressure is present in the system, a nitrogen leak test must be performed before any regas can take place. This helps identify leaks and ensures compliance with F-Gas regulations.
