AC Gas Leak Scam: Read This Before You Say Yes to an AC Gas Refill
Summer has set in, and across cities like Pune, Mumbai, and Bengaluru, air conditioners are back in full-time use. Along with that comes the annual ritual of booking an AC service.
And almost every year, many homeowners hear the same line midway through servicing: “Sir, gas leak hai. Refill karna padega.” Sometimes, that’s true. But in many cases, it may not be.
Here’s what you need to know before agreeing to an AC gas refill.
Why the AC Gas Leak Scam Works So Easily
The biggest reason this trick works is simple. Most of us don’t know what the correct gas pressure level in an AC should be.
When a technician says there’s a leak, we have no way to verify it. So we trust the diagnosis and agree to pay for a refill that can cost anywhere between ₹2,000 and ₹4,000 or even more, depending on the refrigerant type.
In genuine cases, gas refilling is necessary. But the problem starts when:
- There is no actual leak
- The pressure is within normal range
- No real refill is done
- You are still charged for it
That’s how unnecessary refills quietly become a common upsell during routine servicing.
How the Typical Gas Leak Claim Plays Out
The pattern is usually the same.
- You book a routine AC service from a local technician or even an authorised service provider.
- The technician starts cleaning the filters and outdoor unit.
- Midway through the job, you are told there’s a gas leak and cooling will drop if not fixed.
- You ask the cost. A quote is given.
- After some negotiation, you agree.
- The technician “refills” the gas and collects payment.
On the surface, everything looks normal. But without checking pressure readings, you cannot be sure whether the refill was required in the first place.
The Key Detail Most Homeowners Don’t Know
Every AC runs on a specific refrigerant gas. Each gas has a standard pressure range when the unit is running and when it is switched off.
If the pressure is within that range, the gas level is usually fine.
Here are the approximate pressure levels for a standard 1.5-ton split AC:
For R32 refrigerant
- Running pressure: 130–140 PSI
- Close pressure: 240–280 PSI
For R410 refrigerant
- Running pressure: Similar to R32
- Close pressure: Similar to R32
For R22 refrigerant
- Running pressure: 60–65 PSI
- Close pressure: Around 150 PSI
These numbers may vary slightly depending on temperature and model, but they give a practical reference point.
How to Protect Yourself During AC Service
You don’t need to be a technical expert. Just follow these simple steps.
Before servicing starts, switch on your AC. Ask the technician to check the gas pressure while the AC is running. Compare it with the running pressure range mentioned above for your refrigerant type. Then ask for the pressure reading again after the AC is switched off. Match it with the close pressure range.
If the readings fall within the expected range, there is usually no need for a refill.
Also remember this: If there is a genuine gas leak, the technician should be able to identify the leakage point. Gas does not just disappear. There has to be a physical leak in the coil, joints, or piping.
If no leak is shown and pressure seems normal, you are well within your rights to decline the refill.
Why Awareness Is Your Best Defence
Most technicians are honest. But like any industry, there are a few who take advantage of customer ignorance.
The moment a technician realises that you understand basic pressure levels and know what to check, the chances of unnecessary refills drop sharply. You don’t have to argue. You don’t have to accuse anyone. Just calmly ask for the readings.
A simple question backed by basic knowledge can save you thousands of rupees. Before you agree to that next AC gas refill, make sure you’ve seen the pressure numbers yourself.
