We're not sifu, but the next door amateur. Not the type that do prawn, but DIY with GaGa.
If u r talking about hissing sound when compressor kick in, that's because of the valve opened, sending refrigerant to the cooling coil. Basically, its a normal activity for car cooling ventilation system. Due to lack of sound proof and rubbish grade recycle prastik desbod in GaGa, hence the hissing sound bcum amplified & u'll be able to hear it eberytaim akon kick in.
To avoid hearing so manytaims hissing sound, plonk your thermostat to maximum level, by right the hissing sound interval will reduced to about 5minutes once, but u will be freezed to death & bore a hole to your wallet as FC may increase by 30%. Otherwise, on FC challenge mode, my thermostat is always on minimal, hence every 15sec the hissing sound will come and go repeatedly.
1 thing noted, when I have no cabin filter running, the hissing sound is super loud, ultra fast cooling!
Meanwhile,
Quazacolt got no PL1-BT series car. He can only give u a general information on technical knowledge. For instance, he may answer u as, "got hissing sound meh? No ark, all my lisang sengtra, inspaliah, ganjil, iswaga oso dun hab hissing sound. But I think its normal geh" such kinda reply

ayam not saying he's wrong as he's a very helpful contributor, but sometimes newbie might get konfiused due to discussion selanged with different vehicle model.
Next week if Raya4 evening got free we can meet up for a short TT la. Me &
lhwj do this
anal annually

Arvinaaaaa basically what david said loh...
should be normal if related to air cond.
insapla car worst, very loud compressor clutch engagement and hissing sound and got other weird lorry like sound/air compressor sound that you hear from tire shops/workshops.
it's only saving grace is decent cabin sound proofing (not engine bay sound proofing so you still hear it VERY clearly outside the car) so once you shut off the door you can barely hear it

from the top of my head been with saga members' TTs, inspira aircond sound is worse than saga, so be thankful la

and no i'm not joking when the engine compartment sound like a bad diesel lorry running lol
