Fix the leak first. Then fill the gas.
Chennai's gas-filling trade runs on repeat business: top up in March, top up again in May. Airam works differently. Every low-gas call starts with a nitrogen pressure test to find the leak. We repair it, pull a vacuum, charge R22, R32, R410A or R290 by weight, and stand behind the work with up to a 90-day warranty.
- Nitrogen leak testing first
- Refrigerant charged by weight
- Up to 90-day warranty

Signs you need this service
Ice on the copper pipes
Frost on the suction line near the indoor unit is the classic sign of a low refrigerant charge.
Cooling fades by afternoon
The AC runs all day but never pulls the room down during Chennai's 40°C peak hours.
Hissing near the outdoor unit
A faint hiss at the flare joints or coil means refrigerant is escaping under pressure right now.
Second top-up this year
If you paid for gas a few months ago and it is low again, you have a leak, not a gas problem.
Warm air from the vents
The compressor runs but the air barely cools, which points to a near-empty circuit.
Power bills creeping up
A low charge forces the compressor to run longer for less cooling, and the meter shows it.

Why it’s worth doing properly
A leak fixed, not rented
A top-up without a repair is rent: the money escapes with the gas. Our leak-test-first policy means we trace the fault under nitrogen pressure and fix it before a single gram goes in.
Charged by weight, not by guess
No billing by gut feel at the gauge. Refrigerant goes in over a digital weighing scale, matched to your unit's nameplate, and the grams are recorded on your invoice.
Trained for every refrigerant
R22, R32, R410A and flammable R290 each demand different pressures and handling. Our background-verified, uniformed technicians carry the tools and training for all four.
Built for Chennai's coastline
Sea air corrodes copper faster here than almost anywhere in India. We know where Chennai units leak, so coil ends, flare joints and U-bends get checked first.

FAQ
Gas Filling — frequently asked
Everything customers ask before booking a first visit.
Refrigerant is not fuel; it does not get consumed. A sealed system holds its charge for years, so low gas always means a leak. Topping up without repairing it means the new gas escapes the same way, usually within weeks. Our nitrogen pressure test finds the fault first, so you pay once.
