AC Gas Filling & Repair Charges
in India: April 2026 Audit
As mechanical engineers with 20 years in the aeronautics industry, we know that a gas leak isn't just a refill issue — it's a structural integrity issue. We've audited the current market rates for April 2026 to ensure Indian households pay a fair price for quality service.
AC Service Charges: April 2026 Rate Card
These are fair market rates verified by the DU Tech Team across Delhi, Mumbai, Chennai, and Lucknow in April 2026. Use this to avoid being overcharged.
| Service Type | Estimated Charge (INR) | DU Tech Team Advice |
|---|---|---|
Full Gas Charge (R-32) Most Common | ₹2,500 – ₹3,500 | Ensure the technician vacuums the system before refilling. Skipping vacuuming causes moisture contamination — a ₹15,000 compressor failure waiting to happen. Ask for nitrogen pressure test before gas fill. |
Full Gas Charge (R-410A) Older Models | ₹3,000 – ₹4,500 | R-410A is being phased out under India's HFC reduction roadmap. If your AC uses R-410A and needs a refill, seriously consider upgrading to an R-32 model — the gas cost alone will recur every 3–5 years. R-410A is being phased out. Consider upgrading. |
Full Gas Charge (R-22) Legacy / Banned | ₹1,800 – ₹2,800 | R-22 is officially banned for new production in India under the Montreal Protocol. If your AC still uses R-22, you are running on recycled/reclaimed gas. This is a strong signal to replace your AC immediately. R-22 is banned. Upgrade your AC now. |
Gas Leakage Detection Diagnostic | ₹300 – ₹600 | A proper leak detection uses an electronic leak detector — not just soap water. Insist on this. Soap water misses micro-leaks in copper joints that will cause another refill within 6 months. Insist on electronic leak detector, not soap water. |
Leakage Repair (Brazing) Structural Fix | ₹500 – ₹1,200 | Brazing (silver soldering) is the correct repair for copper pipe leaks. Reject any technician who offers to "tape" or "seal" a gas leak — that is not a repair. After brazing, demand a nitrogen pressure test at 300 PSI for 30 minutes. Demand nitrogen pressure test after brazing. |
Jet Service (Wet Wash) Annual Must-Do | ₹500 – ₹800 | A wet jet service cleans the evaporator coil with high-pressure water, removing dust, mold, and bacteria buildup. This is essential for maintaining 2026 5-star efficiency — a dirty coil can reduce ISEER performance by 15–20%. Essential for maintaining 5-star efficiency. |
PCB (Circuit Board) Repair Complex Repair | ₹1,500 – ₹4,000 | PCB repair costs vary wildly. A simple capacitor replacement is ₹500; a full PCB replacement can be ₹3,500–₹4,000. Always get a written estimate before authorizing PCB work. If PCB + gas refill together exceed ₹6,000, consider upgrading. Get written estimate before authorizing PCB work. |
Compressor Replacement Major Repair | ₹8,000 – ₹18,000 | If your AC is more than 5 years old and needs a compressor replacement, the DU Tech Team strongly recommends buying a new 2026 5-star AC instead. A new compressor costs ₹8,000–₹18,000 and comes with only a 1-year warranty — vs a new AC with a 5–10 year compressor warranty. For ACs 5+ years old, buying new is smarter. |
Annual Maintenance Contract (AMC) Best Value | ₹1,200 – ₹2,500 | An AMC from the brand's authorized service center (Daikin, LG, Voltas) covers 2 services per year + priority response. At ₹1,200–₹2,500/year, it's the best insurance for your AC investment. Avoid third-party AMCs — they often use non-genuine parts. Only buy AMC from brand's authorized center. |

R-32 vs R-410A vs R-22: Which Gas Does Your AC Use?
R-32
Current StandardBest choice. Eco-friendly, efficient, and the 2026 BEE standard. All new ACs use R-32.
R-410A
Being Phased OutAcceptable but expensive. If your AC uses R-410A and needs a refill, consider upgrading to R-32.
R-22
Banned in IndiaBanned for new production. Running on recycled gas. Replace your AC immediately — this is a ticking clock.
