Why Your Aircond Gas Keeps Running Out — Real Causes & Solutions

If your aircond keeps running out of gas every few months, this means there is a leak in the system. Aircond gas does not “finish by itself”. Below is a clear breakdown of the real causes, how to fix them, and other common aircond problems Malaysian homeowners face.

1. Common Causes of Aircond Gas Leakage

• Worn copper pipe insulation – Heat exposure causes the foam to break down, leading to condensation and gas leakage.
• Loose flare joints – Poor installation or vibration causes gas to escape slowly.
• Corroded copper pipes – Common in coastal or humid areas.
• Indoor or outdoor coil pinhole leaks – Usually due to age or acidic moisture.
• Previous “top-up only” service – Gas was topped up without repairing the leak.

2. Solutions to Stop Aircond Gas from Running Out

• Pressure test nitrogen to confirm leakage points.
• Replace damaged copper pipes or reflare joints properly.
• Repair or replace leaking coils depending on severity.
• Do full vacuuming before refilling the refrigerant.
• Avoid cheap gas top-up services that don’t fix the root cause.

3. How to Prevent Aircond Gas Leakage

• Ensure proper installation by certified technicians.
• Use high-quality copper pipes & insulation.
• Do regular servicing every 3–6 months.
• Avoid switching the aircond on/off too frequently.
• Check outdoor piping condition yearly.

4. When to Call for Professional Service

If your aircond becomes less cold, makes noise, or leaks water, these are early signs of leakage or clogged components. Fixing it early can prevent expensive coil replacement or compressor failure.

Frequently Asked Questions (FAQ)

1. Does aircond gas finish naturally?

No. If gas is low, there is a leak somewhere that must be repaired.

2. How long should aircond gas last?

If the installation is good, the refrigerant can last 5–10 years or more.

3. Is gas top-up enough?

No. You must find and repair the leak. Topping up only is temporary.

4. Why does my aircond leak water?

Blocked drain pipe, dirty coil, or clogged blower fan.

5. When should I do chemical cleaning?

If airflow is weak, coil is clogged, or bad smell appears, chemical cleaning is recommended.
