5 Signs Your AC Needs Gas Refilling in Indore

Updated February 2026

“Gas bharwana hai” is one of the most common requests AC technicians hear in Indore, but not every cooling issue is caused by low gas. Here are five symptoms that genuinely suggest a gas refilling and leak check may be required.

1. Ice Formation on Indoor or Outdoor Coils

Low refrigerant can cause pressure and temperature changes that lead to ice build-up on coils. If you see ice on pipes or fins, switch off the AC and call a professional instead of continuing to run the unit.

2. Weak Cooling Even After Proper Service

If filters and coils are already cleaned but the room still takes very long to cool, a gas issue is more likely. Technicians should check pressures and look for oily marks along the piping to locate leaks.

3. Hissing or Bubbling Sounds from the Lines

Unusual sounds along copper lines or joints can indicate a leak point. In such cases, simply topping up gas without repair will not solve the problem for long.

4. Sudden Drop in Cooling Performance

If cooling suddenly becomes poor after years of normal operation, and there are no major changes in room usage or temperature, a leak is a strong possibility and should be checked quickly.

5. Very Low Pressure Readings During Testing

Accurate diagnosis requires gauges and, ideally, nitrogen testing. A good technician in Indore will confirm pressure readings before suggesting refilling so you don’t spend money blindly.
