02 / THE DIFFERENCE
CRAFTSMANSHIP, NOT GUESSWORKCustomer write-ups repeatedly mention careful checks, practical repair options and hands-on workmanship. It is the kind of specialist attention an aircon problem deserves.
Told me they must do a definitive check before recommending any repairs. Not pushy at all.— Calvin Lim · public review excerpt

04 / CUSTOMER VOICES
“Went for "not cold" situation and a quick diagnosis found pipe leaking. Given options and chose to replace a new pipe without hesitation! Boss and team friendly and quick to assist! From being baked to chilled! 😂”
“Gotta love this guy - Ah Chong, the most cheerful mechanic you will ever meet. Arrived early morning without appointment - my Macan’s AC system was losing “coldness” and probably due to a gas leak somewhere.…”
“Just had my cooling coil replaced by them. Excellent service! 👍 They clearly showed me the exact area where the cooling coil was leaking and explained the issue professionally. I also noticed several other workshops sending their cars here for repairs, which speaks volumes about their expertise.…”
“Went to two workshops in Ang Mo Kio and Tampines for diagnosis of my non-functioning aircon. Both of the workshops insisted my compressor needed to be replaced after checking for less than 5 minutes. One of them quoted $535 and the other $500.…”
“The AD workshop needs 3 days to change the cooling coil, they changed a new air con cooling coil for me within half a day. They know what they are doing. The rate was reasonable as well.”
“Great service and nice people there. The boss is a very patient and knowledgeable person. Knows what he is doing and troubleshoot whichever issues for my air con compressor. Unlike some other companies which insisted me on changing the whole compressor without any further troubleshooting.…”
“Car aircon started blowing hot air last week and was detected to have a leaked cooling coil after gas fully emptied after 1 day. Left the car with uncle Kim’s technician overnight, which the dashboard & trims all tear down to change the spoilt cooling coil.…”
“Locating the place was a little challenging as my GPS is getting cranky. Parking is difficult as well. Ah Khim attended to me, I believe he is the boss or the manager of the shop. My aircon was not working well.…”

Not every cooling issue needs a full compressor replacement. Describe your symptoms and ask the workshop about diagnosis and repair options.
Contact the workshop first to check availability and the best time to bring your car in.
Your car make, model and year; what the aircon is doing; and when the problem started. Photos or a short description may help the workshop advise on a check.
