What causes Car AC Gas Leak?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- O-ring seal degradation at AC pipe connections — slow leak over years
- AC condenser fin corrosion from stone chips and road dust
- Evaporator coil pinhole corrosion inside dashboard
- Rubber hose cracking from age and heat cycling
- Schrader valve (service port) seal failing — gas escapes from charging port

Frequently asked questions
My car AC needs gas every year in Hyderabad — where is the leak?
If your AC needs recharging every year, there's definitely a leak. Leaks too small to cause visible oily residue can only be found with UV dye injection and a UV lamp, or an electronic halogen leak detector. Metre Per Second injects UV dye, recharges the system, and then checks all connections, hoses, condenser, and evaporator with UV light to pinpoint the leak location. Most leaks are at O-ring seals (₹2,000–₹5,000 to fix).
