Hi John,

Compressortech in Warwick do a refurb service and have dealt with some of our members over the years:

It's always best to replace the condenser at the same time, they can be sourced from Jules on here for about £50.

Whoever recharges the system should drain the system, flush it and then add the correct amount of oil to the recharge.
