How Much Does It Cost To Top Up Aircon Gas In Singapore?

The cost to refill aircon gas in Singapore typically ranges between $60 and $150. Air conditioner refrigerant topping-up cost depends on factors such as gas type and aircon system and the chosen service provider. In this blog, we will try to give you an estimate of recharging aircon gas based on these factors. Let’s find them out.

Aircon Gas Refill Cost in Singapore

As I mentioned, several key factors influence the cost of aircon gas refill such as the specific refrigerant gas used and the aircon system type. Below are the estimates considering these factors:

Cost Based On Gas Type

The price of gas is different for different refrigerants. Therefore, the cost will vary based on the gas that has been used in your aircon unit.

• R32 (Energy-efficient Models): R32 refrigerant provides both environmental benefits and energy efficiency. Its refill cost falls between SG$70 and SG$120.
• R22 (Older Aircon Models): Old aircon units use R22 as their refrigerant gas. The cost of an R22 gas refill will likely increase because the gas is being phased out and its availability is becoming scarce. R22 top-up services will cost between SG$80 and SG$120.
• R410A (Newer Aircon Models): R410A serves as a standard refrigerant in modern air conditioning units. The amount needed to replenish R410A refrigerant gas falls between SG$60 and SG$100.

Cost Based on Aircon Type

Gas refill costs will vary based on the type of aircon you are considering.

• Single-split Aircon: Single-split Aircon features one compressor connected to a single air conditioner unit. The cost of topping up gas for this aircon type ranges from SG$60 to SG$90 depending on the specific refrigerant used.
• Multi-split Aircon: Multi-split air conditioning systems operate with several indoor units linked to a single outdoor compressor. The amount required to refill gas for multi-split systems varies between SG$100 and SG$150 based on the number of necessary units.
• Central Aircon Systems: The pricing for central air conditioning systems in big homes or offices falls between SG$120 and SG$150.

Residential Vs Commercial Aircon

• Residential Aircon Systems: Air conditioning systems for residential properties generally have smaller sizes and require less refrigerant than larger systems. A residential aircon unit gas refill service generally costs between SG$60 to SG$100. The cost varies based on the specific gas type and the total aircon units in the residence.
• Commercial Aircon Systems: Air conditioning systems used in commercial buildings are generally larger and more complex than residential systems. Commercial aircon systems require gas top-ups that cost between SG$100 to SG$150 which depends on both the size of the system and the quantity of gas needed. Central aircon systems located in offices or large commercial spaces face higher costs because they require larger amounts of refrigerant.

AC Gas Top-up Cost FAQs

What is the recommended frequency for topping up aircon gas?

Aircon gas refills occur infrequently unless the system develops a leak. You can refill during regular servicing every year before the season starts if it is required.

What happens if my aircon runs low on gas?

Aircon loses cooling ability and may result in higher electricity costs when it runs low on gas. A low gas level in your aircon results in diminished cooling performance. It can lead to higher electricity costs.

Can I refill the gas myself?

You should not attempt to top up the aircon gas yourself. The proper performance of aircon gas top-up requires professional technicians who possess both the necessary tools and safety expertise.

Does the routine aircon maintenance service cover aircon gas top-ups?

Several aircon servicing packages across Singapore integrate gas top-ups during regular maintenance. Verify this with your service provider before order confirmation.

Are there any additional costs involved?

The gas refill cost includes potential additional expenses such as inspection fees or servicing charges.
