If your air conditioner is blowing warm air or taking longer than usual to cool, low refrigerant may be one possible cause. LK Brothers provides professional aircon gas top up in Singapore for R22, R410A and R32 air conditioning systems.
Our technicians inspect the cooling condition, check for possible refrigerant leakage, refill the correct gas type and test cooling performance after the service.
Published prices start from $65.40 for R22, $87.20 for R410A and $109.00 for R32, inclusive of 9% GST and transportation. Completed jobs include a 90-day workmanship warranty.
These symptoms can be related to low refrigerant, but they may also have other causes. The system should be checked before refrigerant is added.
Weak or warm airflow may occur when refrigerant pressure is too low.
Ice or frost on the refrigerant piping can indicate a cooling-system problem that requires inspection.
Hissing or bubbling noises may indicate refrigerant escaping from the system.
Low refrigerant may cause the system to take longer to reach the desired temperature.
Repeated refrigerant loss can indicate a leak or another fault that should be diagnosed.
R22, R410A and R32 refrigerant service with transparent GST-inclusive pricing.
Different air conditioning systems are designed for different refrigerant types. The refrigerant used must match the requirements of the aircon system.
For compatible R22 air conditioning systems. Published price: $65.40 – $130.80.
For compatible R410A air conditioning systems. Published price: $87.20 – $163.50.
For compatible R32 air conditioning systems. Published price: $109.00 – $196.20.
If your aircon repeatedly loses refrigerant, simply adding more gas does not address why the refrigerant level keeps dropping.
Our gas top-up process includes inspection and leak or pressure testing where required before refrigerant is refilled.
If a refrigerant leak or another system fault requires repair, see our aircon repair and troubleshooting service.

We inspect the system before adding refrigerant, then verify cooling performance after the refill.
Check cooling performance and detect possible gas leakage.
Perform vacuum and pressure testing before refilling gas where required.
Top up the system using the correct R22, R410A or R32 refrigerant.
Monitor temperature, airflow and gas pressure after the refill.
Proper inspection helps determine whether the system needs a gas top up or further repair.

An aircon gas top up may be required when refrigerant pressure is low. Common signs include:
These symptoms can also have other causes, so the aircon should be inspected before refrigerant is added.
LK Brothers' published aircon gas top up prices in Singapore are:
Possible signs of an aircon refrigerant leak include:
Leak detection and pressure tests can help determine whether refrigerant is escaping from the system.
LK Brothers' published gas top-up service covers:
The refrigerant type must match the air conditioning system.
Repeatedly topping up refrigerant without addressing a leak is only a temporary solution.
If refrigerant keeps dropping, the system should be inspected and the source of the leak diagnosed. For repair work, see our aircon repair and troubleshooting service.
Low refrigerant can affect the cooling performance of your air conditioning system.
The existing LK Brothers service guidance states that an aircon gas top up usually takes around 30 to 45 minutes per unit, including inspection and testing.
Yes. Completed aircon gas top-up work comes with a 90-day workmanship warranty.
If low refrigerant is not the cause of your aircon problem, servicing, deeper cleaning or repair may be more appropriate.
