AC gas refill and service

Low gas, weak cooling, or the AC is due for a full service.

Why this happens

  • Refrigerant slowly leaks out over the years
  • Weak cooling and longer run-time are the first signs
  • Ice on the pipes or a hissing sound
  • After any pipe or joint repair the gas needs topping up

Safe checks you can try

  1. First clean the filters to be sure the weak cooling is not just dust
  2. Look for ice on the copper pipe or oil marks at the joints (a leak sign)
  3. Note the AC tonnage and type (split or window) for the technician
  4. A gas top-up needs pressure gauges and a leak fix, so it is a technician job
Never let anyone refill the gas without fixing the leak first. It will finish again in weeks and waste your money.
