Onida AC Gas Leakage Repair in Chennai
Refrigerant leaks starve the coil, so cooling drops off and the unit runs non-stop.
Onida ACs, particularly older Inverter and split models with high-efficiency copper and aluminum heat exchangers, can experience performance drops when refrigerant leaks develop. Because a leak starves the evaporator coil of R-22, R-32, or R-410A gas, the unit loses its thermal absorption capacity. The compressor continues running non-stop to meet the target temperature, leading to heavy power consumption, reduced airflow cooling, and potential compressor overheating if left unaddressed in Chennai's humid climate.
Common Symptoms of Gas Leakage in Onida Units- Gurgling or mild hissing sounds coming from the indoor evaporator unit or connecting copper lines.
- Ice formation or frost build-up on the indoor coil bends or the outdoor unit's brass service valves.
- Warm air blowing from the louvers while the outdoor compressor runs continuously without tripping off.
- Unusually high electricity bills caused by prolonged cooling cycles.
- Formicary corrosion on copper U-bends in high-humidity areas, creating microscopic pinhole leaks.
- Vibration-induced friction cracks at the flare nut joints connecting the indoor and outdoor units.
- Deteriorated rubber O-rings or loose service valve cores on the outdoor unit port.
- Thermal stress fractures in the evaporator coil solder joints due to constant expansion and contraction.
- Nitrogen Pressure Testing: We isolate the system, charge it with dry nitrogen gas, and monitor pressure drops to locate micro-leaks safely.
- Bubble & Electronic Detection: Soap bubble solutions and electronic leak detectors pinpoint the exact leak location on coils or copper piping.
- Brazing & Flare Repair: Our technicians use silver-brazing rods to seal coil punctures or cut and re-flare damaged copper tubing connections.
- System Vacuuming: We pull a deep vacuum using a two-stage vacuum pump to remove all moisture and atmospheric air from the lines.
- Precision Gas Charging: We weigh in the exact factory-specified refrigerant (R32, R410A, or R22) to restore optimal operating pressures.

Frequently asked questions
Why is ice forming on my Onida AC indoor coil?
Ice formation usually indicates low refrigerant pressure caused by a gas leak. When refrigerant levels drop, the evaporator coil temperature falls below freezing, causing ambient moisture to freeze on the fins.
Can I just refill gas in my Onida AC without fixing the leak?
No, topping up gas without sealing the leak is a temporary fix, as the new refrigerant will eventually escape. Janani Cool Care always locates and seals the leak before vacuuming and refilling the gas.
How long does an Onida AC gas leak repair take?
A complete repair—including nitrogen pressure testing, coil brazing or flare nut correction, evacuation, and refrigerant charging—typically takes between 2 to 3 hours.
Do you offer a warranty on gas leak repair services?
Yes, Janani Cool Care provides a 30-day service warranty on all leak repairs and gas topping services completed by our technicians.
