I went to Mang Danny at Seaoil based on the recommendations on this board and they are spot on -- Mang Danny is the best! My aircon was shutting off when hot and two shops said either busted na magnetic coil or compressor needs replacement (11K-20K estimates). Mang Danny diagnosed it as normal wear and tear on the pulley. He took off the pulley face from the compressor (while on the car so hindi nasayang freon) and removed a paper thin washer. With the new tighter tolerances, wala nang problema sa aircon! Mukhang sanay magbaklas ng compressor si Mang Danny. Very knowledgeable and maayos kausap -- he explains things to you very clearly. He even repaired my noisy fan by replacing the motor with a very clean surplus unit he had on-hand (insides looked brand new). All in all, less than 1K singil sa akin. Nag follow up pa one week after asking if everything was fixed. Highly recommended!
