Reliable Aircon Gas Top-Up Services in Singapore

Is your aircon not cold, showing blinking lights or making hissing sounds? Heng Aircon provides safe and fast aircon gas top-up services using accurately measured R22, R410A and R32 refrigerant. Our technicians check your system before refilling, so the right amount of gas is added to help restore cooling performance properly.

Aircon Gas Top Up Price Guide & Packages

Aircon gas top up price can vary depending on the refrigerant type, the current gas level and whether your system needs a partial or fuller refill. Heng Aircon checks your aircon before topping up, so you get the right refrigerant and amount for your unit instead of a rough estimate.

R32 Gas Top-Up

R32 is commonly used in newer residential aircon units and is considered a modern, more eco-friendly refrigerant option. A partial R32 gas top-up may usually range from about $80 to $120, while a fuller refill may range from about $120 to $180, depending on the system condition and gas level.

R410A Gas Top-Up

R410A is commonly found in many aircon units that are around 5 to 10 years old. A partial R410A gas top-up may usually range from about $80 to $120, while a fuller refill may range from about $120 to $180. Our technician will check the pressure level before confirming the required amount.

R22 Gas Top-Up

R22 is used in some older air conditioning systems. A partial R22 gas top-up may usually range from about $60 to $100, while a fuller refill may range from about $100 to $150. If your system requires frequent R22 top-ups, our technician may also check for possible leaks or advise whether repairs are needed.

Final pricing will depend on your aircon model, refrigerant type, pressure reading and site condition. A proper inspection helps avoid unnecessary top-ups and ensures the service is carried out safely.

Do You Need an Aircon Gas Top Up? Look for These Signs

Low refrigerant levels can affect cooling performance, raise running costs and place extra strain on your air conditioning system. If you notice any of the signs below, it may be time to book an inspection before deciding if an aircon gas top-up is needed.

Not Blowing Cold Air

If your aircon is running but the room still feels warm, low refrigerant may be one possible cause. The system may struggle to absorb and release heat properly, making cooling slower and less consistent.

Ice Forming on the Evaporator Coil or Copper Pipes

Ice on the indoor coil or copper piping can happen when refrigerant levels are too low or airflow is restricted. This should not be ignored, as continued operation may worsen the issue and affect other components.

Higher Electricity Bills

When the aircon does not cool efficiently, it may run for longer periods to reach the set temperature. Over time, this can lead to higher electricity bills, especially if the system is used daily.

Hissing or Bubbling Noises

Hissing or bubbling sounds may point to a refrigerant leak. In this case, topping up gas alone may not solve the problem. A proper check is needed to confirm the leak source before recharging the system.

Our Professional Process for Gas Top Up Aircon Services

A proper gas top-up aircon service should never be done by guesswork. Heng Aircon checks the system condition, pressure and cooling performance before adding refrigerant, so your aircon receives the right support instead of a quick refill that may not address the root problem.

System Pressure Diagnosis

Our technician checks the refrigerant pressure using suitable gauges to understand the current gas level and system condition. This helps determine whether the aircon gas top-up is actually required.

Leak Identification (The Truth About Gas)

Aircon refrigerant does not get used up like fuel. If the level is low, there may be a leak or an issue within the system. We check for possible signs of leakage so the right repair advice can be given before topping up.

Secure Pipe Connections

Loose or worn connections can allow refrigerant to escape. Our technician checks key connection points and advises if tightening, repair or replacement work is needed before the system is recharged.

Accurate Refrigerant Recharging

Once the system is ready, the correct refrigerant type is added, such as R22, R410A or R32. The amount is measured carefully to avoid undercharging or overcharging, both of which can affect performance.

Final Commissioning & Temperature Check

After the gas top-up, we test the aircon’s operation, cooling output and temperature performance. This final check helps confirm that the unit is cooling more effectively before the job is completed.

FAQs about Aircon Gas Top Up in Singapore

How do I know if my aircon needs a gas top-up?

Common signs include weak cooling, warm air, ice forming on the coil or copper pipes, hissing sounds and higher electricity bills. However, these symptoms can also be caused by other faults, so it is best to arrange a professional aircon service before topping up gas.

How often should I top up aircon gas?

A properly installed and sealed aircon system should not need frequent gas top-ups. If you keep needing refrigerant refills, there may be a leak or component issue. An aircon technician in Singapore can inspect the system and advise what needs to be fixed.
