Why AC Gas Leakage Happens & How to Prevent It
In Karachi’s hot and humid climate, air conditioners work overtime to keep homes and offices cool. Unfortunately, AC gas leakage is a common issue that leads to poor cooling, higher electricity bills, and frequent repairs. At Air Fix Masters Karachi, we explain why AC gas leaks happen, how to spot the signs early, and best prevention tips to keep your AC running efficiently.
✅ What is AC Gas Leakage?
AC units rely on refrigerant gas (R22, R410a, R32) to absorb heat and cool your room. When this gas leaks, the AC loses its cooling capacity and overworks itself, which can damage key components like the compressor.
✅ Common Causes of AC Gas Leakage in Karachi
🔧 1. Weak Joints or Loose Connections
✔️ Poor installation or aging AC pipes can develop loose connections, causing gas leakage.
🔧 2. Corrosion of Copper Pipes
✔️ Karachi’s salty air and humidity cause corrosion in copper pipes, leading to small holes and leaks over time.
🔧 3. Vibration Damage
✔️ Constant vibration from outdoor units, especially in apartments, can weaken joints or crack pipes.
🔧 4. Faulty Flare Nut Fittings
✔️ Incorrect tightening during AC installation or maintenance can cause leakage from flare nut joints.
🔧 5. Accidental Damage
✔️ Physical damage during renovations or shifting can break AC gas lines or indoor coils.
✅ Early Signs of AC Gas Leakage
✔️ Low Cooling or No Cooling
✔️ AC Running Continuously Without Cooling the Room
✔️ Ice Formation on Indoor Unit
✔️ Hissing Sound from AC Pipes
✔️ Sudden Spike in Electricity Bills
✅ How to Prevent AC Gas Leakage
✅ 1. Always Use Certified Technicians
✔️ Professional installation reduces faulty joints and fitting issues.
✅ 2. Regular AC Servicing
✔️ Schedule maintenance every 3-4 months to check gas levels and inspect joints.
✅ 3. Anti-Rust Coating for Outdoor Units
✔️ Especially near coastal areas like Clifton, DHA, and Bahria Town, applying anti-rust protection helps prevent pipe corrosion.
✅ 4. Gentle Handling During Shifting or Cleaning
✔️ Avoid pipe bending, rough cleaning, or accidental impacts during servicing.
✅ 5. Quality Spare Parts
✔️ Always use high-quality copper pipes, flare nuts, and branded materials during installation and repairs.
