AC Gas Filling Price in Kadapa (R32, R410A, R22)
If your AC has stopped cooling and a technician says it needs 'gas refilling', you should know two things: (1) gas refilling in Kadapa costs ₹2,000 for a top-up and ₹3,000 for a full refill — not more — and (2) a properly installed AC should never need gas refilling. This guide breaks down the real prices, the difference between top-up and full refill, and when you're being overcharged.

Top-up vs full refilling — which one do you actually need?
Choose top-up (₹2,000) when:
- Your AC was cooling fine 6+ months ago, gradually got weaker
- Pressure gauge shows 60–80% of normal pressure
- No visible signs of major leakage (no oil stains on copper joints)
- System is 3+ years old with normal wear
Choose full refilling (₹3,000) when:
- AC stopped cooling suddenly within days/weeks
- Pressure gauge shows near-zero — system is empty
- Oil stains visible at copper pipe joints (clear leak)
- Previous top-up didn't last more than a few months
- AC was uninstalled and reinstalled recently
R32 vs R410A vs R22 — what gas is in your AC?
R32 — used in most ACs sold in India after 2018. Eco-friendly (low GWP), slightly more energy efficient. Cheaper to source and refill. Standard rate.
R410A — common in 2010–2018 split ACs. Slightly more expensive than R32 but plentiful supply. Standard rate.
R22 — older window ACs and split ACs from before 2010. Being phased out globally as it harms the ozone layer. Supply is shrinking, so refilling costs ₹500 more. If your R22 AC needs frequent refills, consider replacing it — newer inverter ACs use 30–40% less electricity and pay for themselves in 3–4 years.
Check the sticker on your outdoor unit — it lists the refrigerant type and the exact charge quantity in grams. A genuine technician will refill that exact quantity, not 'estimate by feel'.
How a proper full gas refilling is done (so you can verify)
- Pressure check — gauge connected to the service port confirms the system is empty.
- Leak detection — soap solution on copper joints, or electronic leak detector for hidden leaks. Common leak points: flare nuts, Schrader valve, indoor coil joints.
- Leak sealing — re-flaring the joint, replacing the Schrader valve, or in serious cases brazing the copper pipe.
- Vacuum — pump runs for 20–30 minutes to remove all air and moisture from the lines (critical step many cheap technicians skip).
- Gas charging — exact factory quantity weighed in (e.g. 850 g for a 1.5 ton R32 split AC).
- Performance test — pressure check on running AC, temperature drop measurement at indoor outlet (should be 11–14°C below room temp).
If your technician skips the vacuum step or doesn't weigh the gas, walk away — that AC will lose gas again within months.
Why does an AC lose gas?
- Loose flare nut at the outdoor unit (most common — bad installation)
- Damaged Schrader valve (the small valve at the service port)
- Vibration cracks in copper pipe over years
- Corrosion in the indoor coil (10+ year old units)
- Damage during AC shifting / uninstall
- Manufacturing defect in the indoor coil (rare, covered under warranty)
Red flags — when you're being overcharged
- Quote above ₹3,500 for a 1–2 ton split AC full refill
- 'Tonnage charge' added separately (₹2,000 should already include up to 2 ton)
- Refusal to show pressure gauge reading
- Refusal to do vacuum before charging
- 'Gas is more expensive this year' (price has been stable since 2023)
- Top-up quoted as 'full refill' to inflate price
- Cash-only with no receipt

Frequently Asked Questions
How much does AC gas filling cost in Kadapa?+
A gas top-up (small leak, partial refill) costs ₹2,000. A full gas refilling (empty system, leak repaired, complete recharge) costs ₹3,000. Prices are the same for R32 and R410A — the most common refrigerants in Indian split ACs. Older R22 systems cost about ₹500 more due to scarce gas supply.
What's the difference between gas top-up and full refilling?+
Top-up (₹2,000) adds gas to a system that has lost some pressure due to a slow leak — takes 30 minutes. Full refilling (₹3,000) is for a system that's completely empty: technician finds and seals the leak, vacuums all lines to remove moisture, then charges the exact factory quantity. Takes 90–120 minutes.
How do I know if my AC needs gas refilling?+
Three clear signs: (1) AC blows air but doesn't cool even after filter clean, (2) ice builds up on the copper pipe at the indoor unit, (3) the outdoor copper pipe stays warm/hot instead of becoming cold during operation. A pressure gauge confirms it in 5 minutes — diagnosis is free.
What gas does my split AC use — R32, R410A or R22?+
ACs sold in India after 2018 mostly use R32 (eco-friendly, slightly more efficient). 2010–2018 models use R410A. Pre-2010 ACs use R22, which is being phased out globally. Check the sticker on your outdoor unit — it lists the gas type.
How often does an AC need gas refilling?+
A properly installed AC should never need gas refilling — it's a sealed system. If yours needs gas every 1–2 years, you have a leak that needs to be found and sealed, not just topped up. Repeated top-ups without leak repair just waste your money.
Why do some technicians quote ₹4,000+ for AC gas filling?+
Be careful. Standard 1–2 ton split AC gas filling in Kadapa is ₹2,000 (top-up) or ₹3,000 (full). Higher quotes either bundle in unrelated 'service charges', use 'tonnage based' pricing dishonestly, or are inflating because they think you don't know the market rate. Always ask for an itemised quote.
Is gas top-up safe or should I always do full refilling?+
Top-up is safe and standard practice when the leak is genuinely slow (gas takes 1+ year to drop). For a fresh, fast leak (gas drops within weeks), full refilling with leak sealing is the right choice — top-up will just leak out again in days.
