i have Teco RA680 1/2HP chiller. but need to do repair on pipe gas leakage.
i've send to Irwarna service by Brother Derrick. he check everything working fine just that there's a leakage of pipe gas that he unable to fix. and i don't have the time to bring around getting someone to repair, he advices me to go to aircon/refridgerator service person. If you have someone that can do this repair better still.
i'm selling at a low price cos i already got myself a 1/2hp chiller. those interested may PM me.
