Quick answer: AC gas (refrigerant) does not get used up. It circulates in a sealed system, so if your AC is low on gas, it has a leak. The leak should be found and repaired first, then the system recharged with the refrigerant type on its label (R22, R410A or R32). Homes on district cooling usually have no refrigerant in the flat at all.
Why doesn’t AC refrigerant run out?
Your split or ducted AC moves refrigerant around a closed loop between the indoor and outdoor units. It changes between liquid and gas to carry heat out of the room, but it is not burned or consumed. A correctly sealed system keeps the same charge for years, so “topping up every summer” is a sign of an unrepaired leak.
What are the signs of an AC gas leak?
- Air from the indoor unit is weak or not cold
- Ice on the indoor coil or on the copper pipes near the outdoor unit
- A hissing or bubbling sound near the pipes
- Oily marks at pipe joints or valves
- The outdoor unit runs for longer than before
- Water dripping as a frozen coil melts
These can have other causes too, such as a dirty filter or a fan fault, so a technician should check before adding gas.
R22, R410A and R32: what’s the difference?
They are different refrigerants. Older units often use R22, many current units use R410A, and newer units often use R32. Each system must be charged only with the type on its rating label. Mixing refrigerants or using the wrong type can damage the compressor. Send us a photo of the outdoor unit label so we know which one your AC uses.
What should district-cooling homes check first?
Many apartment towers use district cooling or a central chilled-water system. Your flat then has a fan coil unit with chilled water, not refrigerant gas, so there is nothing to top up. If cooling is weak, check the thermostat, the filter and the building’s cooling supply, and contact building management. We help with split units and your own appliances.
What does a proper repair involve?
Finding the leak, repairing the joint or part, pressure and leak testing, then recharging with the correct refrigerant and checking cooling. Avoid “gas only” top-ups that don’t fix the leak.

FAQ
- Does AC gas run out and need regular top-ups?
No. Refrigerant circulates in a sealed loop and is not used up. If the gas is low, there is a leak, and it should be found and repaired before recharging. - What are the signs of an AC gas leak?
Weak or warm airflow, ice on the indoor coil or copper pipes, a hissing sound, oily marks at joints, the outdoor unit running longer, or water dripping from a frozen indoor unit. - What is the difference between R22, R410A and R32?
They are different refrigerant types. Older units often use R22, many current units use R410A, and newer units often use R32. A system must be recharged only with the type on its rating label; they must not be mixed. - My apartment has district cooling. Can you top up the gas?
District-cooling and central chilled-water systems don’t use a refrigerant gas in your flat. Contact building management first; we help with split units and your own appliances. - How much does an AC gas top-up cost?
