guys,

patulong naman, have been 2 AC shops na already and sumisingaw pa rin yung freon from my AC system. Binaba na yung evaporator, compressor, checked na rin yung condenser and AC line, wala namang makitang butas.
Pati yung low pressure hose tiningnan na rin wala naman. The last AC shop i went to napansin yung joint ng high pressure hose may play so we had the joint replaced and re-crimped pero after 2 days bawas na naman yung freon. Any ideas kung saan pa pwede
magkabutas at sumisingaw yung freon ?

thanks
