BBA can give you or your customer real savings. A very large percentage of compressor problems are just a clutch,coil or bearing problem. Rather than the £350 to £800 for a new compressor, a typical clutch rebuild by us will be £100-£150. At the moment we are offering free collection.
AIR CONDITIONING DIAGNOSIS (see below for air conditioning basics)
The first thing to do if an air conditioning system has failed is to check for a leak. This may seem the most obvious thing todo, but it is not always carried out! It is vital because oil is mixed with the refrigerant, so even the slightest leak willeventually lead to their being no oil in the system. This will lead to costly damage to the compressor and other components of the system.
Customer arrives with aircon inoperative. Fuses are OK, clutch not operating. Refrigerant pressuresare tested OK, Control Module reveals no codes. Could be either high pressure cut out switch (cuts above approx 400psi)or low pressure (cuts out below 40 psi approx). You can very briefly use a jumper wire to test these switches.
Compressor Clutch Bearing Failure
can result from three causes:-
(i) Excessive refrigerant pressures, causing compressor to work too hard. This melts the bearing grease.
(ii) Insufficient clutch coil voltage means coil draws too much current, heats up, and heat melts bearing grease. (Voltage should be no lower than battery voltage minus 1v)
(iii) Pulley Bearing nose housing distorts due to overheating. Bearing thus not supported correctly and fails.Call for free help and free testing. Because if you're in any doubt about whether your compressor may have brokenup and put debris in to the system we will collect it free of charge. Upon disassembly we can report back as towhether you need a new condenser, a complete system flush, or as in many cases there are no problems otherthan your clutch needs replacing.Flushing Complete system flushing is a requirement after any compressor replacement (also a warranty stipulation). Alllines, evaporator, condenser, must be thoroughly flushed with proper power flush equipment. If compressor failed badlycondenser will likely need replacement.
