One of the most common questions Malaysian homeowners ask their aircond technician is: “How much does gas top-up cost?” It is a fair question, and unfortunately, the answer is not always straightforward. Prices vary widely depending on the type of refrigerant, the amount needed, and — frankly — which company you call. Some operators charge as little as RM 50, while others quote RM 200 or more for the same service.
In this article, we provide a transparent breakdown of aircond gas top-up costs in Malaysia as of 2025, explain what you are actually paying for, and share why PJ Kool Aircond Service includes gas top-up free with every chemical wash.
Current Gas Top-Up Prices in Malaysia (2025)
The cost of a gas top-up depends primarily on two factors: the type of refrigerant your aircond uses and how much gas needs to be added. Here are the typical price ranges you will encounter in the Petaling Jaya and Klang Valley area:
R22 (Freon) — Older Units
- Price per top-up: RM 80 to RM 180
- Why it costs more: R22 is being phased out globally under the Montreal Protocol. Production and import have been significantly reduced, making existing stock more expensive. The price has been increasing by roughly 10 to 15 percent each year.
- Typical units: Airconds manufactured before 2010-2012
R410A — Mid-Generation Units
- Price per top-up: RM 60 to RM 130
- Availability: Widely available with stable pricing
- Typical units: Airconds manufactured between 2010 and 2019
R32 — Current Standard
- Price per top-up: RM 60 to RM 120
- Availability: Excellent, as it is the current standard
- Typical units: Most airconds manufactured from 2018 onwards
These prices typically include the technician’s service call and the gas itself. However, some companies charge a separate call-out fee of RM 30 to RM 50 on top of the gas price. Always confirm the total cost before agreeing to the service.
What You Are Actually Paying For
A gas top-up is not just about pumping refrigerant into your system. A proper gas top-up service should include:
1. Pressure check. The technician connects manifold gauges to your system to measure the current refrigerant pressure. This tells them exactly how much gas has been lost and whether the pressure readings are within the manufacturer’s specifications.
2. Leak assessment. If your system needs a gas top-up, it means gas has escaped somewhere. A responsible technician will check for obvious leaks before simply adding more gas. Common leak points include the piping joints, valve connections, and indoor unit coil. If there is a significant leak, adding gas without fixing it is a waste of money because the gas will just leak out again.
3. Gas addition. The technician adds the appropriate amount of refrigerant to bring the system back to its specified charge level. This must be done carefully — overcharging is just as damaging as undercharging.
4. Performance verification. After the top-up, the technician should check the system’s cooling output and temperature differential to confirm it is working correctly.

Why Some Companies Charge So Much More
If you have shopped around for gas top-up prices in PJ and the Klang Valley, you have probably noticed a wide range of quotes. Here is why:
Separate call-out fees. Some companies charge RM 30 to RM 50 just to come to your location, then add the gas charge on top. Others include the call-out fee in the total price. Always ask for the all-inclusive price.
Unclear pricing structure. Some technicians charge “per PSI” (per unit of pressure added) rather than a flat rate. This can lead to unexpectedly high bills, especially if a significant amount of gas is needed. We recommend asking for a flat rate or a maximum price before the work begins.
Upselling unnecessary services. Unfortunately, some operators use a low gas top-up price to get in the door, then “discover” additional problems that require expensive repairs. While legitimate issues do sometimes arise during servicing, be cautious of technicians who consistently find problems beyond what you called about.
Quality of refrigerant. Not all refrigerant gas is the same quality. Counterfeit or contaminated refrigerant exists in the Malaysian market, and using it can damage your compressor. Reputable service providers use branded, certified refrigerant.
Why PJ Kool Aircond Service Includes Gas Top-Up Free
At PJ Kool Aircond Service, we include gas top-up at no additional charge with every chemical wash service. Here is why we made this decision:
Most gas top-ups are needed during servicing anyway. When we perform a chemical wash, we check refrigerant pressure as a standard part of the process. If the gas is slightly low, it makes no sense to charge separately for a top-up that takes minutes and uses a small amount of refrigerant.
It removes a common source of customer frustration. Nobody likes being surprised by extra charges. By including gas top-up in our chemical wash price, you know exactly what you are paying before we arrive.
It encourages regular maintenance. When customers know that gas top-up is included, they are more likely to schedule regular chemical washes rather than waiting until their aircond stops cooling. This preventive approach keeps systems running efficiently and reduces the need for costly repairs.
It builds trust. The aircond service industry in Malaysia has a reputation for hidden charges and upselling. We prefer to offer a transparent, all-inclusive price that customers can rely on.
When a Gas Top-Up Alone Is Not Enough
While gas top-up is a common service, it is important to understand that it is not always the right solution:
If your system loses gas repeatedly (every 3 to 6 months), there is an active leak that needs to be found and repaired. Continuously topping up gas without fixing the leak is like filling a bucket with a hole in it. Common leak locations include soldered pipe joints, flare connections, and the evaporator coil itself.
If your aircond is not cooling despite having correct gas pressure, the problem lies elsewhere — dirty coils, a failing compressor, a blocked capillary tube, or an electrical issue. A gas top-up will not help in these situations.
If your system is completely empty of gas, this indicates a major leak. The system should not be recharged until the leak is located and repaired, and a vacuum test should be performed before recharging to ensure the repair is successful.

Tips for Malaysian Homeowners
Ask for the total price upfront. Before agreeing to any gas top-up service, confirm the all-inclusive price including call-out fee, gas, and labour.
Know your refrigerant type. Check the label on your outdoor unit so you know which gas your system uses. This helps you verify that the technician is charging the correct rate and using the right refrigerant.
Keep service records. Note the date and amount of each gas top-up. If you need a top-up more than once a year, there is likely a leak that needs attention.
Consider a chemical wash instead. If your aircond is blowing warm air, the cause is often dirty coils rather than low gas. A chemical wash that includes a gas check and top-up addresses both possibilities at once, and is usually better value than a standalone gas top-up.
