whistling sound when a/c engages

[tonyboy]

hi mga sir,

ask ko lang what the source or cause could be kasi may parang may napito na sound (mga 1 second) inside sa dashboard passenger side when the compressor engages? it happens mga every 2 to3 minutes. pag off ang compressor wala naman sound.

TIA

share ko lang, naririnig ko yan sa kia rio namin, after a month ubos na freon. ayaw na lumamig ng aircon, pagkarefill ng freon mawawala na yung sound na yon, intay pa tayo feddback ng mga experts.

that happened to my corolla when i replwced my evaporator with an replacement parts. its not an original and different design but it is an exact fit. its been 6 months of momentary whistling everytime mag automatic ang a/c,la nan prob.

sir same here, paparefill ako freon kasi mababawasan lamig. tapos after mga 1 month bawas ulit lamig. pansin ko pag bagong refill may sipol.

sir its a classic sign of low freon level, check for leaks
