Can overfilling gas damage the AC system in Suzuki Wagon R?

I recently visited a roadside AC technician who told me he “topped up” the gas in my 2017 Wagon R. After that, the AC cooled well for a few days, but now it feels like it’s struggling to cool even on full blower. I read online that overcharging the AC system can cause damage. Is it true? What symptoms show AC gas has been overfilled, and how can I get it fixed?

Yes, overcharging the AC system with too much refrigerant is harmful and can lead to:

Symptoms of Overfilling:

Weak o r no cooling despite cold compressor pipe

High pressure in the system, causing compressor overload

AC system shutting off intermittently

Possible damage to compressor seals and hoses

Common Reasons in Pakistan:

Roadside mechanics often top up gas without checking pressure.

Gas refilled without proper vacuuming and gauges.

What to Do:

Visit a qualified AC technician who can:

Use manifold gauges to measure system pressure

Recover excess gas and refill with the correct amount

Inspect for long-term compressor damage

Tip: Always demand a proper vacuum + pressure test before gas filling. Dont rely on gas top-up blindly.
