System re-charge and general service check £50.00 + VAT.

The above price is for vehicle systems containing refrigerant type R134a which is common to most vehicles. However a new refrigerant branded as R1234YF is now in use on most new vehicles. R1234YF is currently very expensive and I would therefore request that interested parties requiring this service contact me verbally or by email for prices.

The above service includes the following:

System pressure test with OFN (oxygen free nitrogen), please see notes below to see why this maybe applicable.  Recovery of refrigerant from system followed by a 20 minute vacuum of the system.  An estimated quantity of PAG (refrigerant) oil, usually 25ml mixed with a flourescent dye.  Correct quantity of refrigerant is then added.  If fitted, I will inspect the pollen / cabin filter as these parts can become seriously contaminated / blocked thus restricting the air flow through your car heating system and may even burn out the the fan speed control resitors as a result. 

6 month backup cover

The above work includes 6 month back up cover which works in the following way:  If your car A/C should fail to operate within 6 months of my re-charging the system, then I will come out and investigate the problem free of charge.  I will spend up to an hour trying to detect any leaks using an ultra-violet lamp / electronic sniffer, also free of charge.  Any remedial work (unless very small) will incur a charge, but I will not charge for re-gassing of the A/C system following the repair work within the 6 month period, that is providing remedial action is undertaken by myself.

Please note the following:

Vehicle air conditioning systems sometimes require other work to be carried out before the system can be re-charged.  For example, if the system is found to be void of any refrigerant pressure, then it is likely that a leak maybe present.  This can take the form of a leaking 'O' ring, corroded pipe, damaged / corroded condenser, leaking A/C compressor or evaporator - the list goes on.  If  the system is found to be void of pressure, then I will first perform a pressure test of the system using OFN (ogygen free nitrogen) and test the system up to a pressure of 10 bar ~ 150 psi.  If the system holds pressure, with no noticeable pressure drop over a few minutes, then I would consider it safe to proceed with the above service.  However, should a leak be present, then remedial action must be taken either by myself or a competent A/C engineer before the system can be re-charged.

It is recommended that the filter dryer be replaced every 2 years regarless of milage, although I am not a firm believer in this policy, I personally believe that the filter dryer should be changed at least every 80,000 miles or when the system has been exposed to air for a period of time.  The filter dryer serves two purposes, that is it filers the system from debris such as internal wear of the A/C compressor and internal flaking of rubber hoses.  It also contains a number of small desecant beads that absorbe moisture contamination that may enter the system in the event of a leak to atmosphere.  Note: moisture contamination may prove to be fatal to a car A/C system.
