AC Gas Refill Cost India2026 Price Guide by Tonnage & Gas Type
How much should you actually pay for AC gas filling? We polled 200+ HVAC technicians across India to bring you real, current prices — so you do not get overcharged.
Quick Answer
AC gas refill costs in India range from ₹2,000 for a 0.8 ton window AC to ₹5,500 for a 2 ton split AC. R32 gas is cheaper (₹2,500–₹3,500 for 1.5 ton) than R410A (₹3,000–₹4,500 for 1.5 ton). Always demand leak detection before refilling — otherwise the gas will leak again within weeks.

When to Refill Gas vs When to Replace Your AC
Do not throw money at an old, leaking unit. Here is the decision framework we use in the field.
Refill Gas
- AC is under 6 years old
- Leak is accessible and repairable (flare nut, visible pipe)
- Total cost of leak repair + refill is under ₹6,000
- Compressor still starts and hums normally
- Unit has good cooling when gas level is correct
Replace the AC
- AC is over 8 years old
- Has needed 2+ gas refills in the past 3 years
- Evaporator coil is corroded or has micro-leaks
- Repair cost exceeds 40% of new AC price
- Electricity bill has risen 30%+ due to inefficient compressor
A new 5-star inverter AC pays for itself in 3–4 years through electricity savings alone. Explore the most efficient models.
Best Energy-Efficient AC in IndiaHow to Avoid Getting Overcharged
Use this checklist when the technician arrives.
Demand leak detection first
A proper technician will pressure-test the system before adding any gas. If they skip this step, find someone else.
Ask for the gas weight
Check your AC manual for the exact refrigerant charge weight (usually 700g–1.5kg). The technician should charge by weight, not by pressure alone.
Get a written estimate
A written quote prevents the classic bait-and-switch where a ₹2,500 quote becomes ₹5,000 after 'unexpected complications'.
Check for warranty coverage
Many brands offer 5-year gas warranties. If your unit is under warranty, the manufacturer should cover gas-related repairs.
Verify refrigerant type
R32 and R410A cannot be mixed. Check your AC's nameplate for the correct type. Wrong gas destroys the compressor.
Ask for post-charge readings
After filling, the suction pipe should feel cold and sweaty. The room should cool 3–4°C in 15 minutes. If not, the fill was incomplete.

AC Gas Refill FAQs
Common questions about AC gas charging in India
How much does AC gas refill cost in India?
AC gas refill costs in India range from ₹2,000 for a 0.8 ton window AC to ₹5,500 for a 2 ton split AC. R32 gas is cheaper at ₹2,500–₹3,500 for a 1.5 ton unit, while R410A costs ₹3,000–₹4,500 for the same tonnage. Labor and leak detection add ₹500–₹1,200 depending on your city and technician.
How do I know if my AC needs gas refill?
Three reliable signs: 1) The larger insulated copper pipe (suction line) feels warm or room temperature instead of cold and sweating when the AC runs. 2) Ice builds up on the indoor coils within hours of defrosting. 3) The room never reaches the set temperature even after 30+ minutes of running. A technician can confirm with pressure gauges — normal suction pressure for R32 is 120–140 PSI and for R410A is 160–190 PSI.
How long does AC gas last?
In a sealed system with no leaks, refrigerant gas lasts the lifetime of the AC — 12–15 years. If your AC needs gas refilling every 1–2 years, there is definitely a leak in the copper lines, flare nuts, or evaporator coil. Never accept a top-up without leak detection and repair. Repeated refills without fixing the leak waste money and eventually damage the compressor.
What is the difference between R32 and R410A gas?
R32 is a single-component refrigerant with lower global warming potential (GWP 675) and better heat transfer efficiency. It requires about 30% less charge weight than R410A. R410A is a blend of R32 and R125 (GWP 2088) and was the standard before 2020. Most new ACs in India now use R32. You cannot mix the two gases — using the wrong gas destroys the compressor. Check your AC label or manual for the correct refrigerant type.
Should I refill gas or replace the AC?
Refill if your AC is under 6 years old, the leak is accessible and repairable, and the total cost (leak repair + refill) is under ₹6,000. Replace if the AC is over 8 years old, has needed multiple refills, the evaporator coil is corroded, or repair costs exceed 40% of a new AC price. A new 5-star inverter AC saves ₹3,000–₹5,000 annually on electricity and comes with a 10-year compressor warranty.
Can I refill AC gas myself?
No. Refrigerant handling requires EPA certification, manifold gauges, a vacuum pump, and precise weighing equipment. Overcharging or using the wrong gas type causes immediate compressor failure. In India, only certified HVAC technicians with refrigerant handling licenses should perform gas charging. DIY attempts also void manufacturer warranties.
Why does my AC need gas every year?
Annual gas loss means a significant leak. Common leak points in Indian ACs: corroded copper evaporator coils (especially in coastal areas), loose flare nuts at indoor/outdoor connections, pinhole leaks from vibration wear, and factory weld defects. A proper technician will pressure-test the system with nitrogen, use a leak detector or UV dye, repair the leak by brazing or replacing the damaged section, then vacuum and recharge with the exact manufacturer-specified weight.
What is included in gas filling service?
A proper gas refill service includes: system pressure testing to confirm low gas, leak detection using electronic detector or nitrogen pressure test, leak repair by brazing or replacing damaged lines, system evacuation with vacuum pump (30+ minutes at 500 microns), precise refrigerant charging by weight using a digital scale, and post-charge performance verification (suction pressure, superheat, and cooling delta). Beware of technicians who skip leak detection and simply top up — the gas will leak again.
