What is a car aircon specialist?
A car aircon specialist is a workshop that diagnoses and repairs only car air-conditioning: refrigerant leaks, compressors, cooling coils (evaporators), condensers, fans and smells. The work starts with tests rather than a quick gas top-up, so the quote fixes the cause. SG Garage, our aircon unit at #01-309 in Ang Mo Kio Industrial Park 2, does aircon work only.

How do we diagnose a car aircon problem?
We test before we quote. Most aircon complaints in Singapore (not cold, cold only when driving, warm at idle, a smell or a noise) can come from more than one part, so each check rules causes in or out.
- Vent temperature and pressure check: gauges on the high and low sides show whether the system is low on gas, overcharged, blocked or not compressing.
- Leak tracing: if the pressure is low, we find where the gas escapes. Common points are hose joints, the compressor seal, the condenser and the cooling coil.
- Compressor and electrical check: clutch engagement, fuses, relays and pressure switches. An electrical fault can stop the compressor and look like a gas problem.
- Airflow check: blower, cabin filter, condenser fan and cooling coil, for weak airflow, poor cooling at idle or smells.
- Clear quote: we explain what we found and what to fix first. Nothing is done until you approve the price.

How to choose a car aircon specialist in Singapore
Whichever workshop you use, these questions help you avoid paying twice for the same fault.
Do they check for leaks first?
A top-up without a leak check often means the cooling fades again within weeks.
Do they show you the cause?
Ask to see the gauge readings or the leak point before you approve a part.
Are prices clear?
Look for starting prices that include parts, labour and GST, with the final price agreed before work starts.
New or remanufactured?
For compressors, ask which option suits your car and why. Remanufactured vs new
Is the repair tested?
The system should be pressure and vent-temperature tested again before you collect the car.
Can you book a slot?
An appointment means your car gets proper time for the checks.

Frequently asked questions
Where is the SG Garage aircon unit?
At Blk 5032 Ang Mo Kio Industrial Park 2 #01-309, Singapore 569535, on the ground floor of the same block as the Edwin Garage main workshop (#01-295). It is about 5 to 10 minutes from Ang Mo Kio MRT.
Does the #01-309 unit do other car repairs?
No. The #01-309 unit does car aircon work only: gas top-up after a leak check, leak checks, compressor, cooling coil, condenser and aircon odour. Servicing, mechanical repair and accident claims are handled at the main workshop, #01-295.
How much is a car aircon gas top-up?
From $20, after a leak check, including parts, labour and GST. If the system is leaking, we show you where and quote the repair before topping up, because gas added to a leaking system escapes again.
How much does a car aircon compressor or cooling coil cost?
Compressor replacement starts from $550 and cooling coil replacement from $600, including parts, labour and GST. The final price depends on the car and is confirmed after inspection. See compressor replacement.
Do I need an appointment for aircon repair?
Yes. Aircon work is by appointment only, booked through the link at sggarageedwin.as.me. We are open Monday to Saturday, 10am to 8pm, and closed on Sundays.
What makes a car aircon specialist different from a general workshop?
A specialist tests the whole aircon system before changing parts: pressures on both sides, leak tracing, compressor clutch and electrical checks, and airflow. That finds the real cause, so you are not paying for repeated gas top-ups or the wrong part.
