Gas doesn't run out, it leaks

An AC is a sealed system. If the gas is low, there's a leak somewhere, usually at a flare joint, a corroded copper pipe, the indoor coil or a service valve. Simply topping up gets the AC cooling again for a few weeks, then it's warm air once more and you pay twice.

We check the pressure, find the leak with soap or electronic detection, repair it, vacuum the system and then charge the correct refrigerant for your model. That's what makes a gas refill last.

Which gas does my AC use?

Most new inverter ACs in Pakistan use R32 or R410A. Older non-inverter units often use R22. The gas type is printed on the outdoor unit's label. Never mix gases; it damages the compressor and voids the warranty.

Our gas refilling process

  1. Pressure check

    We connect gauges and confirm the gas really is low, not a fan, coil or electrical fault.

  2. Find the leak

    We test joints, pipes, valves and coils to locate the leak.

  3. Repair and vacuum

    The leak is fixed, then the system is vacuumed to remove air and moisture.

  4. Charge and test

    We charge the correct gas, then check pressures, current and outlet temperature.

AC gas refilling FAQs

How often does an AC need a gas refill?

A correctly installed AC with no leak shouldn't need gas for many years. If you need gas every season, there's a leak that hasn't been fixed.

Is a gas leak covered by my AC warranty?

Sometimes. Many brands cover gas leaks only for a short period after installation. Check your warranty card, and see our guide to AC warranty and gas leakage in Pakistan.

Can low gas damage the compressor?

Yes. Refrigerant also cools the compressor. Running for long periods on low gas makes it overheat and can lead to failure, the most expensive repair on an AC.

How long does a gas refill take?

A top-up with a simple leak repair takes about an hour. A full recharge with vacuuming can take one to two hours.
