Air conditioning is essential for daily comfort in Malaysia’s tropical climate. However, when an aircond stops cooling, one of the most common concerns homeowners have is whether the unit needs a gas refill.
Before deciding, it’s important to understand what aircond gas does, how to know when it is low, how much it costs in Malaysia, and most importantly—the difference between a simple refill and a gas leak problem.
This guide will help you make the right decision and avoid unnecessary spending.
What Exactly Is Aircond Gas?
Aircond gas (also known as refrigerant) is the chemical that absorbs heat and cools the room. When the gas level is correct, your aircond cools efficiently.
The three main gas types used in Malaysia are:
R22 – Older models
R410A – Newer models
R32 – Latest, more efficient models
Each gas type has a different price and refill method.
Do You Need a Gas Refill? (Warning: Not Always)
Many customers misunderstand aircond cooling problems and immediately request gas refill.
In reality, aircond gas never “finishes” by itself.
If it becomes low → there is a leak somewhere.
Signs your aircond MAY have low gas:
Takes a long time to cool
Weak airflow
Ice forming on indoor coil
Outdoor unit running nonstop
Air feels slightly cool but not cold
If you’re unsure, a technician must test the gas pressure.
Aircond Gas Refill Price in Malaysia (2025 Updated)
Below are the average market rates used across Klang Valley, Subang Jaya, USJ, Puchong, Shah Alam, and Kuala Lumpur.
R22 Gas Refill (Older Models)
RM 80 – RM 150
Used for older wall units
Cheapest gas type
Being phased out but still common in older homes
R410A Gas Refill (Newer Inverter + Non-Inverter Units)
RM 120 – RM 200
High-pressure gas
Requires proper tools and correct reading
Required for split-unit inverters and some non-inverters
R32 Gas Refill (Latest Technology)
RM 150 – RM 260
Most efficient cooling
Higher pressure
Better for electricity savings
Standard for most new airconds in Malaysia
Prices vary based on HP (horsepower), gas type, access to outdoor unit, and whether leak repair is required.
Why Aircond Gas Becomes Low (The Real Reason)
Gas does NOT evaporate.
If gas is low, it means:
✔ There is a leak in the system.
Leaks usually come from:
Rusted copper pipe
Loose pipe joints
Installation mistakes
Indoor coil corrosion
Outdoor unit vibration
Old rubber insulation
Warning:
Refilling gas without fixing the leak = money wasted.
The gas will leak again within days or weeks.
Gas Refill vs Leak Repair — What’s the Difference?
Gas Refill Only
✔ If the system has a tiny, slow leak
✔ Cooling improves immediately
❌ But leak may return
Leak Detection & Repair
✔ Pressure test
✔ Soap test
✔ Nitrogen test
✔ Tightening joints
✔ Replacing damaged sections
This is the proper long-term solution.
How to Know If Your Technician Is Skilled
A professional technician should:
✔ Test gas pressure before refilling
✔ Show the reading
✔ Identify if there is leakage
✔ Explain which gas type your unit uses
✔ Avoid “overfilling”
✔ Ensure outdoor unit is cleaned and not blocked
Poor technicians often only refill gas without checking anything—this is dangerous and wasteful.
How Often Should Gas Be Refilled?
Ideally: Never
If the system is healthy, gas does not need yearly replacement.
If you need gas refill every 3–6 months → there is a major leak that must be fixed.
How Much Gas Does Your Aircond Need? (HP Guide)
| Aircond Size | Gas Required (approx.) |
|---|---|
| 1.0 HP | Low to medium refill |
| 1.5 HP | Medium refill |
| 2.0 HP | Medium to high refill |
| 2.5 HP | Higher volume refill |
| 3.0 HP | High refill |
Technician will determine exact amount using pressure gauge.
When Should You Avoid Using the Aircond?
Stop using immediately if:
The unit freezes with ice
Water is leaking heavily
Outdoor unit vibrates unusually
Gas smell is detected (rare but dangerous)
The compressor switches ON/OFF rapidly
These are signs of gas shortage or blockage.
