Apologies for necro-ing this thread, but wanted to ask if anyone has any recommended AC Repair Workshops around Klang Valley (KL / PJ) area that provides great and clean workmanship for Cooling Coil replacement for a 2012 KIA Forte.

Ideally one that takes care not to damage any parts of the Dashboard during removal / reinstallation.

Many thanks in advance for the recommendations.

Thank you.

Well, I was also hoping that the issue would not be Cooling Coil / Evaporator Core related.
Alas, that is not the case - as I could almost clearly hear the hissing sound of the Refrigerant / Freon Gas leaking when I parked at a silent basement car park with engine turned off.

My suspicion started when the AC started to gradually lose its coolness about a little under 2 years ago.
My first troubleshooting / rectification attempt was a visit to Ming Wah to flush-service the AC system.
At the time, I believe the leak was still very gradual - hence, no hissing sound and the AC was able to retain its cooling function for more than 1 year after aforesaid service.

I went for a gas-recharge again, circa Sep / Oct 2024, when the AC started feeling less cool.

Thereafter (sometime this Apr'25), the AC lost its cooling function completely > and I brought it to my neighborhood workshop for a recharge.
The hissing sound, described above, was detected by me after I drove home from said recharge service.

TL;DR version:
• Confirm cooling coil problem because Freon-Refrigerant is leaking (TS could hear hissing sound plus smell).
• TS have already been to Ming Wah, but would still like to know if there are any other good / great recommendation from Forumers here.
• Reason why TS would like to have other recommendations:
- 1st priority [WORKMANSHIP]: To ensure no damage to dashboard / other parts (as close to 100% as reasonably possible).
- 2nd priority [CLEANLINESS]: As in TS hopes that the workshop / repairman would make the best effort to keep the customer's vehicle interior clean.

Pray tell, which stop leak product did you use?

Also, was the product effective - as in did you AC / Cooling Coil stopped leaking from then until now (present)?

How many years / months have passed since you last used the stop leak product to fix said leak?

Thank you very much for the info / sharing.

One last question, how bad was the AC leak in your car at that time?

Gradual leak = AC leaking refrigerant over a course of weeks / months.

Large leak = AC leak with complete loss of refrigerant within 24 to 48 hours.

If you don't mind sharing, what was your Car Brand, Model and Year of Manufacture?

Reason for asking:
I'd like to research a bit more to see if there are any distinct difference(s) between my car and your car - hoping that there are none; so that I have more confidence to attempt said method.

At the end of the day, I really hope to be able to avoid Dashboard removal - but if it doesn't work, well. . .what choice do I have right 😅

One other question; would you happen to still have the Shopee (I'm assuming you bought the product there) link for the Stop Leak product?

What bottle size you purchased?

Also, what were the steps you took to apply the Stop Leak - if for example, the AC system is completely discharged (zero refrigerant).
