AC Gas Leak Detection & Refill

The classic signs are: the AC runs but the airflow isn't cold, ice forms on the indoor coil, or your electricity bill goes up while cooling gets weaker. These can also indicate a blocked filter, a failing compressor, or a sensor fault — so we don't recommend a refill on symptoms alone. We confirm with a nitrogen pressure test on site before recommending any gas work.

If the leak is at a joint or flare, the full sequence — pressure test, repair, vacuum, and refill — typically takes 60–90 minutes on site. Coil-level leaks are slower because the coil may need to be removed or swapped, which can extend the visit to half a day. We give you a time estimate after the pressure test, before starting any repair.

If there's an actual leak in the system, top-up gas just escapes again over the next few weeks — you've paid for refrigerant that's now in the atmosphere. The proper fix is to pressure-test, find the leak point, repair it, and then charge the system to the manufacturer's spec. We only do a straight top-up if the pressure test comes back clean and we're confident there's no active leak.

Yes. R22 is being phased out under the Montreal Protocol but is still serviceable, and we keep stock available for refills and leak repairs. That said, R22 cylinder prices have been climbing year-on-year — for older units we'll tell you upfront whether continued R22 refills make sense or whether replacing the unit with a modern R32 system is more economical over the next 2–3 years.

Yes — we cover the specific joint or coil we repaired with a 30-day workmanship warranty. If the same point leaks again within that window, we come back and re-fix it at no charge. If a different part of the system develops a separate leak later, that's a fresh diagnostic, but AMC clients get discounted rates on follow-up work.

Detection (nitrogen pressure-test) starts at ₹500. Refill cost depends on the gas type and the quantity needed: R22 (older units), R32 (most modern units), and R410A (some inverter units) are all priced separately and we share the per-cylinder rate before charging anything. A typical 1.5-ton split that needs a partial refill — assuming a single small leak we can repair on the spot — lands in a defined range we'll quote on site after the pressure test. We don't quote a flat "gas refill" price upfront because that almost always means topping up gas without finding the leak, and the gas just escapes again in a few weeks.

A "top-up" usually means adding refrigerant without finding why pressure dropped in the first place. If there's a real leak — at a flare joint, a coil micro-fracture, or a corroded line — top-up gas escapes through the same path within weeks. A proper refill is the full sequence: nitrogen pressure-test to locate the leak, repair the joint or coil, vacuum the line, then charge to the manufacturer's spec. We do top-ups only when the pressure test comes back clean and we're confident there's no active leak.

Same-day gas refill visits are standard across central and western Pune — Kothrud, Baner, Warje, Bavdhan, Aundh, Wakad, Hinjewadi, Katraj, Swargate, Hadapsar, and Central Pune. Further-out neighborhoods inside Pune city (within roughly 35 km of the city centre) typically get a next-day slot. The pressure-test, leak repair, vacuum, and charge sequence usually finishes in a single visit unless the leak is at coil level, in which case we may need a second visit for the coil swap.
