Why do i need to have my A/C system serviced?

All vehicles air conditioning systems leak to a lesser or greater degree. The losses occur through refrigerant escaping through the pipe joins as a result of vibration and ageing of rubber hoses and ''O'' ring seals , as well as through the seals on the front of the compressor shaft

How often should theA/C system be Inspected or Serviced?

An annual  Inspection is sufficient to check system conditions  and over all performance . A service of the system should be  carried out  at least every year even if it appears to be working well. It is estimated that you lose between  20-30 % of the intial gas  change over a two year period and this figure is based on new vehicles. RadioAutoSonic Air Conditioning Specialist can provide a comprehensive list  of all checks carried out and produce a report on the condition of the system.

Is it true that the  vehicles A/C system should often run throughout the year?

Yes , this  helps to keep the system well lubricated and leak tight.


Because the refrigerant actually carries the oil that lubricates the system , most importantly the compressor. It also keeps the seals and hoses moist , thus preventing them from drying out and cracking leading leaks.

Whats involved in a service?

We measure the pressures in the system , check quality of the refrigerant present with a Gas Analyser and check all functions. Then we recover the refrigerant and vacuum the system down to a very low pressure (Deep Vacuum process) to remove any moist that may be present . We then Re-Charge (Re-Gas) with new refrigerant R134a and also add a measured amount of the correct type of lubricant for your system. We also add Ultra Violet dye to help find any leaks that may develop in the future.
