Why Does Your AC Keep Losing Gas? Major Causes & Permanent Solutions | Delhi Daily Service
Posted on : 24-Feb-2026
There is nothing worse than surviving the scorching summer heat only to find your air conditioner blowing warm air. When you call a technician, the diagnosis is often the same: "Sir/Ma'am, the gas has leaked, it needs to be refilled."
But this raises an important question: if an AC is a closed system, where does this gas keep going? Is it consumed like fuel in a car?
In this blog by Delhi Daily Service (DDS), we are going to uncover the truth behind AC gas leakage and explain why simply "topping up" the gas is never a permanent fix.
First, Understand the Basics: AC Gas is NOT Like Fuel
One of the biggest misconceptions is that air conditioners consume gas (refrigerant) over time. This is completely false.
The refrigerant in your AC runs in a sealed loop. Its only job is to absorb heat from inside your room and release it outside. In an ideal, healthy AC system, the gas should never run out. If your AC is low on gas, it means only one thing: there is a hole or leak in the system.
Major Reasons for AC Gas Leakage
If you find yourself paying for a gas refill every season or every few months, one of these culprits is likely to blame:
-
Vibrations and Loose Connections: When your AC runs, the outdoor unit constantly vibrates. Over time, these vibrations can cause the flare nuts connecting the copper pipes to loosen. These loose joints act as an easy escape route for the gas.
-
Rust and Corrosion: In cities like Delhi, pollution, humidity, and nearby open drains emit gases that react with the copper coils of your AC (especially the outdoor condenser). This causes corrosion, creating microscopic pinholes in the metal where the gas leaks out.
-
Poor Installation Quality: If the copper pipes were bent forcefully or the welding (brazing) at the joints was done poorly during the initial installation, those weak spots will eventually give way and start leaking.
-
Worn-out Rubber Seals: The service valves on your AC use rubber O-rings to keep the system sealed. Due to extreme heat and aging, these rubber seals dry out, become brittle, and lose their sealing capacity.
Is Just Getting a "Gas Top-Up" the Right Solution?
Absolutely not! It is a complete waste of your hard-earned money.
Many local technicians will simply come, hook up their cylinder, refill the gas without finding the leak, and leave. Your AC will work perfectly for a few weeks or months, but because the hole is still there, the gas will eventually leak out again.
Getting a top-up without fixing the leak is like constantly pouring water into a bucket with a hole in it.
The Delhi Daily Service (DDS) Approach: We Fix the Root Cause
At Delhi Daily Service, we don't believe in temporary band-aid solutions. When you book us for an AC gas charging service, we follow a strict, professional protocol:
-
Thorough Leak Detection: Our trained technicians use nitrogen pressure testing and soap solutions to pinpoint the exact location of the micro-leak.
-
Permanent Repair: Once the leak is found, we fix it permanently through professional brazing (welding) or by replacing the damaged part entirely.
-
Deep Vacuuming: Before adding new gas, we use a vacuum pump to remove all trapped air and moisture from the system, ensuring maximum cooling efficiency.
-
Precise Gas Charging: Finally, we charge the exact amount of high-quality refrigerant required for your specific AC model, measured precisely by weight and pressure.
Conclusion:
Repeated AC gas leaks are not just heavy on your wallet; they are also harmful to the environment and can permanently damage your AC's compressor. Stop paying for endless top-ups.
