Gas top-up

Aircon gas top-up in Singapore

10 companies whose name or customers' public reviews mention gas top-up. Low gas usually means a leak. Find it before refilling.

Refrigerant is not used up in normal operation, so low levels almost always mean there is a leak (Helpling). A top-up without finding the leak only lasts until the gas escapes again, so ask the technician to check for the leak first.

What it costs

Helpling publishes gas top-up from about S$100 to S$130 a unit depending on the refrigerant (R22, R410A or R32), with figures that vary between its own pages (Helpling price list).

Signs you need it

  • The unit runs but the air is not cold
  • Ice forming on the pipes
  • Water dripping after the unit is switched off (melting ice)
  • A hissing sound near the pipes

What to ask the company

  • Will you check for the leak before topping up?
  • Which refrigerant does my unit use (R22, R410A or R32)?
  • Is the price for a full or half top-up?
  • What if it is low again next month?

Gas top-up: questions

How often does an aircon need a gas top-up?

Ideally never. Refrigerant runs in a sealed loop and is not used up, so a unit that needs topping up has a leak that should be found and fixed.
