5 Warning Signs Your AC Needs Gas Refilling Before Summer

As summer temperatures rise in Kolkata, your air conditioner becomes the most essential appliance in your home. However, one of the most frequent reasons an AC blows warm air is low refrigerant (gas) levels caused by microscopic leaks or regular wear and tear.

Top Warning Signs of AC Gas Leakage:

• Warm or Luke-Warm Airflow: Even at 18°C or 20°C, the air coming out of the vents does not feel crisp or cold.
• Ice Buildup on Copper Pipes: When refrigerant drops below optimal levels, condensation on the evaporator coils freezes into visible frost or ice.
• Hissing or Bubbling Sounds: A physical refrigerant leak often produces a faint hissing sound near the outdoor unit or flare connections.
• Spike in Electric Bills: The compressor runs continuously without cycling off to meet the set temperature, consuming excessive energy.

Expert Tip: Simply adding gas without fixing the leak will result in gas escaping again within weeks. Always hire a certified technician to conduct nitrogen pressure leak testing before refilling R32 or R410A gas.
