Published guides generally quote roughly ₹2,000 to ₹4,500 for a split AC gas refill, depending on gas type, tonnage and city, with leak repair extra. A sealed AC does not use up gas, so low gas normally means a leak. Insist on a leak test before any refill.
AC gas refilling is one of the most common services in summer and also the one customers most often feel overcharged for. This guide explains what drives the cost, the price ranges commonly quoted in India, and how to make sure you only pay for what your AC actually needs.
Typical AC gas refill price ranges
| Gas type | Commonly found in | Indicative range for a split AC |
|---|---|---|
| R22 | Older ACs | Around ₹1,500 to ₹3,500 |
| R32 | Most newer ACs | Around ₹2,500 to ₹3,500 |
| R410A | Some newer and inverter ACs | Around ₹3,000 to ₹4,500 |
Prices go up with tonnage (a 2-ton AC takes more gas than a 1-ton), with leak repair or pipe work, and in cities with higher labour costs. A bill that includes a leak check, vacuuming and a pressure test should cost more than a quick top-up, and it is the one that actually solves the problem.
What affects the cost?
- Type of gas: R22, R32 and R410A have different prices.
- AC capacity: a larger system holds more refrigerant.
- Leak repair: welding or replacing a pipe, or fixing a flare joint, adds to the cost.
- Service included: vacuuming, nitrogen testing and cleaning raise the price but improve the result.
- Location and urgency: peak-season and emergency visits may cost more.
Does your AC really need gas?
An AC’s gas circuit is closed. Unlike petrol in a car, the refrigerant is not used up. If your AC is low on gas, it has leaked out somewhere, usually at a joint, a flare nut, a service valve or a corroded coil. Topping up without fixing the leak means the problem returns in weeks or months.
Signs of low gas
- The AC runs but cools weakly, or only on some days
- Ice on the copper pipe or on the indoor unit
- Hissing or bubbling noises
- Higher electricity bills with poor cooling
- The outdoor unit runs constantly
Other problems cause the same symptoms: dirty filters, a clogged outdoor coil, a weak capacitor or a faulty sensor. Read our guide on why your AC is not cooling before assuming it needs gas.
How to avoid being overcharged
- Ask for a gas pressure reading and a leak test before any refill.
- Ask which gas your AC uses and check the outdoor unit label yourself.
- Agree the price first. Get the quote before the gas is opened.
- Be wary of “full refill” claims. A technician who recommends a complete refill without testing the system may be guessing.
- Ask for the leak location. A good technician can tell you where it was and what was done.
- Ask about warranty on the gas fill and the leak repair.
Can I check the gas myself?
You can look for symptoms such as weak cooling or ice on the pipe, but only a technician with a gauge can measure the gas pressure and test for leaks. Do not attempt to open or refill the system yourself. Refrigerants are pressurised and need proper handling.
