Aircond Gas Top-Up Myths in Malaysia — What's True, What's Not
Many Malaysian homeowners have been misled about aircond gas top-ups. This guide busts the most common myths.
Myth 1 — "Gas needs to be topped up every year"
False. A properly installed aircond with no leaks does not lose gas. If your unit needs top-up every year, there is a leak that must be found and repaired first.
Myth 2 — "Any amount of gas is fine"
False. Both too little AND too much refrigerant damage the compressor. Professional technicians use a manifold gauge for exact pressure measurement.
Myth 3 — "R22 can be replaced with R410A"
False. R22 and R410A are incompatible. Never mix refrigerant types. Continue using R22 until the unit needs replacement.
Myth 4 — "More gas = colder air"
False. If gas is already at correct pressure, adding more harms the compressor. Always measure first.
Myth 5 — "R32 costs much more"
R32 top-up is slightly higher in cost but uses less volume, so the total difference is smaller than it appears.
What a Proper Gas Top-Up Includes
- Leak check before adding gas
- Current pressure measurement
- Correct amount added
- Final pressure verification
- Cooling performance test
