Why your aircon needs a gas top up

Refrigerant (aircon gas) is what actually cools the air inside your unit. Over time, a system can lose refrigerant through wear, ageing seals, or a small leak, causing your aircon to blow warm air, cool more slowly, or form ice on the indoor coil. A gas top up recharges the refrigerant back to the correct level so your aircon can cool properly again.

Gas top up is not always the right fix on its own. If a leak is causing the low gas level, simply adding more refrigerant only provides temporary relief before it escapes again. That is why GreenCool always checks the system for leaks first, before recommending a top up or a repair.

We work with all major refrigerant types used in Singapore homes and offices, and recharge each system to the level recommended for that model.

JOB SCOPE

  • Check refrigerant pressure and overall system performance
  • Inspect the system for visible gas leaks before any top up
  • Identify the correct refrigerant type for your unit (R22a, R410a or R32a)
  • Recharge refrigerant to the manufacturer-recommended level
  • Test cooling performance after the top up

Price (for systems with no gas leak)

  • R22a$50 – $150
  • R410a$80 – $180
  • R32a$80 – $180

Prices apply to non gas-leak systems. If a leak is found during inspection, GreenCool will recommend the right repair before any top up.

    Aircon Gas Top Up FAQs

    Short answers to common questions.

    What is aircon gas top up and when do I need it?

    Aircon gas top up refers to recharging the refrigerant in your air-conditioning system. You may need a gas top up when your aircon takes longer to cool, blows warm air, or ices up. GreenCool checks for gas leaks first, then tops up the correct refrigerant type so your aircon cools efficiently again.

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

    Common signs include weaker cooling than usual, warm air from the vents, ice forming on the indoor coil or pipes, and the compressor running longer than normal. These symptoms usually point to low refrigerant, but a technician should check for leaks before topping up.

    How much does aircon gas top up cost in Singapore?

    Gas top up pricing depends on the refrigerant type: R22a from $50 to $150, and R410a or R32a from $80 to $180. These prices apply to systems with no gas leak — if a leak is found, GreenCool will recommend the right repair first.

    What is the difference between R22a, R410a and R32a refrigerant?

    These are different refrigerant types used across aircon models and ages. Older systems commonly use R22a, while newer systems typically use R410a or R32a. Using the correct refrigerant type for your system is important for safe and efficient cooling — GreenCool identifies the right type for your unit before topping up.

    Is gas top up covered if my aircon has a leak?

    Topping up gas on a system with an active leak only provides a temporary fix, since the refrigerant will escape again. GreenCool checks for leaks before any top up and will recommend the appropriate repair so the gas top up lasts.

    How can I book a gas top up service?

    You can call GreenCool at +65 6844 8588 or submit a request through the website service form, and a technician will get back to you to arrange a visit.
