Most gas leaks start in the pipes

The copper pipes between the indoor and outdoor units carry refrigerant under high pressure. Loose or badly made flare joints, pipes bent too sharply during fitting, corrosion from Lahore's humid monsoon and rubbing against walls can all cause slow leaks.

We locate the leak, then repair it properly. That means re-flaring joints, cutting out and brazing damaged sections, or replacing the pipe run. Then we pressure-test with nitrogen, vacuum the system and recharge the gas.

Signs of a pipe leak

  • Oily marks on pipe joints or the wall behind them
  • Cooling drops a few weeks after a gas refill
  • Frost on the thin copper pipe
  • Hissing near the outdoor or indoor unit
  • Torn or missing pipe insulation

Why insulation matters

Exposed suction pipes sweat in humid weather and lose cooling before the gas reaches the indoor unit. In direct sun on a Lahore rooftop, bare pipes also heat up the refrigerant. Replacing torn insulation is cheap and makes a noticeable difference.

Copper pipe repair FAQs

Can a leaking AC pipe be repaired or must it be replaced?

Most leaks at joints can be repaired by re-flaring. Badly corroded or kinked pipes are better replaced. We'll show you the damage and recommend the cheaper lasting option.

Do I need a gas refill after pipe repair?

Usually yes, because some or all of the gas has leaked out. After repairing we vacuum the system and charge the correct gas.

Can you extend AC pipes when shifting the AC?

Yes. We add brazed extensions and keep the total length within what the manufacturer allows, then pressure-test and vacuum.
