AC Gas Refilling

AC Gas Refilling Charges: What Decides the Price

Gas isn’t used up like fuel — a unit that needs repeated top-ups has a leak, so the honest cost includes finding and fixing it. Charges depend on:

• The refrigerant your AC uses (R22, R410A or R32)
• The tonnage, and whether it’s a split or window unit
• A top-up versus a full recharge after the leak is repaired
• Leak detection and brazing, if the leak needs sealing

R32 vs R410A vs R22: Which Gas Does Your AC Use?

The refrigerant type is printed on the rating label on the outdoor unit (and usually in the manual). As a rule, older units use R22, while most newer split ACs use R410A or R32.

• They are not interchangeable — each system is built for its refrigerant, so never mix gases or “top up” with a different one
• R410A systems run at higher pressure than R22 systems
• R32 is mildly flammable and should be handled by a trained technician

How to Detect an AC Gas Leak

Signs include warm or weak air, ice on pipes or coils, a hissing sound, oily residue at pipe joints, a compressor that runs for long hours, and a rising electricity bill.

A leak can’t be confirmed by eye. A technician finds it by pressure testing the system and checking the likely points — flare joints, service valves, and the indoor and outdoor coils — then seals it by brazing or repair before recharging. Refilling without fixing the leak only buys a few weeks. See 5 signs your AC needs gas refilling and why your AC bill keeps climbing.

AC Freezing Up: Ice on the Unit

Ice on the indoor coil, pipes or outdoor unit usually comes from restricted airflow (a dirty filter or coil), low refrigerant, or a weak blower or fan.

• Switch cooling off and run fan mode so the ice melts
• Don’t chip the ice or restart cooling while the unit is frozen
• Rinse the filter once it has thawed

If it freezes again, there’s an underlying fault, most often a leak, and it needs a check. Meltwater can also overflow — see water dripping from the indoor unit.
