Don't melt in your car this summer

As part of a regular car service we will check for obvious faults in the air conditioning system, such as drive belt tension, visible signs of refrigerant leaks and loose or faulty compressor or equipment mounting brackets. It's good practice to have a dedicated air conditioning service for best cooling results.

If your air-conditioner is not cooling as it should then you most likely have a refrigerant gas leak. The design of a car air-conditioner requires many pipes and hoses which means many joins, each with a potential to leak refrigerant gas in minute quantities. A new car will have lost enough gas in 24 months to impact on the air-conditioner performance. The diagram to the right will give you some idea of the complexity of identifying a leak in so many components with so many hoses, joins, seals and fittings to go wrong.

Run Your Air-conditioner During Winter

Running your AC during winter also helps to maintain the system in good working order. Air conditioning systems contain a myriad of hoses and seals that can dry out or crack, which could lead to refrigerant leaks and poor performance. View our AC information page...

Car air conditioning systems - everything you need to know.

Here is what we do when we service your car air-conditioner:
  • Inspect cabin air filter
  • Inspection of hoses and components
  • Check operation of valves and thermostats
  • Inspection of drive belts and pulleys
  • Evacuate system and recover refrigerant (weigh amount and record)
  • Add required amount of compressor oil
  • Charge system with recommended refrigerant type
  • Condenser air flow and temperature check
  • Suction line temperature reading
  • Action leak test procedure
  • Run system and check vent temperatures
  • Observe opration of condenser fans

Your Health and Auto Air-conditioning.

Due to the very nature of vehicle air-conditioning it is a potential harbour for fungi, mould and various bacteria. The air-conditioner evaporator is where these nasty creatures gather. The damp of the evaporator causes airborne particles to stick and ultimately provide a breeding place for all things smelly and unhealthy.

There is a cabin air filter in most modern vehicles but sadly it is mostly overlooked during scheduled servicing. If the filter has been replaced every 12 months then your evaporator may still be okay, otherwise it may be necessary to remove it and physically scrub the rubbish off it and disinfect it.
Beware There are some repair shops offering a 'quick fix' its a spray on deodorant to mask the evaporator generated smell, it is not a fix, it is a masking agent and the bacteria and the problem is still there. Its cheaper but what price your health?

Tips For Maintaining a Car Air Conditioner.

Running the air conditioner once a week for 10 minutes will maintain the gas pressure. This prevents hardening of the hoses and compressor seals failure. Turn the air conditioner to its coolest setting and highest fan speed. Run the ‘defrost’ mode for five to ten minutes to clean out accumulated moisture. This prevents mildew and prevents that dirty wet cloth odour in the system.

Remember, your air conditioning system does not only cool your vehicle but in addition one of its primary functions is to remove the humidity from the cabin. So it is good practice to use your air conditioner in winter to keep your windscreen free of fog which impairs your visibility. By allowing all car windows to remain closed, even on the hottest days, the aerodynamics of the car remain at optimum, keeping fuel consumption low and exterior noise to a minimum, increasing safety to the driver and passengers.
