Aircon Gas Leak On-site

In Singapore’s hot and humid climate, a reliable air conditioning system is not just a luxury—it’s a necessity. But even the best aircon units can develop problems over time, and one of the more common issues faced by homeowners and businesses alike is a gas leak. This often causes the aircon to stop cooling efficiently or not cool at all. View more.

At LetsCool Aircon and Services, one of Singapore’s most trusted aircon companies, we frequently get this question:

Can a technician fix an aircon gas leak on-site?

The answer is yes, in most cases, but it depends on several key factors. Let’s dive into what you need to know.

What Is an Aircon Gas Leak?

Air conditioners work by circulating refrigerant gas (commonly R22, R32, or R410A) through the system to absorb heat and cool your indoor space. A gas leak happens when this refrigerant escapes due to wear and tear, corrosion, poor installation, or physical damage to the copper piping.

When there's a leak, your aircon might:

• Blow warm or cool air

• Struggling to cool the room even after running for hours

• Show signs of freezing on the indoor unit

• Start making hissing or bubbling noises

• Display blinking error lights

Ignoring a gas leak can lead to increased energy bills, compressor damage, and complete system failure. That’s why it's important to have it checked and fixed as soon as possible.

Can It Be Fixed On-Site?

In many cases, yes, a qualified technician from LetsCool Aircon and Services can repair a gas leak on-site. However, the repair process depends on the location and severity of the leak.

• Common On-Site Repair Scenarios:

Loose or Damaged Flare Joints

Flare joints (where the copper pipes connect) can loosen over time, leading to small gas leaks. Our technicians can tighten or replace these joints quickly and safely on-site.

Minor Pipe Corrosion or Small Punctures

If the leak is small and located on an accessible section of the copper pipe, it can be patched or welded on the spot. After sealing the leak, we will perform a vacuum test and top up the gas to the required pressure.

Indoor/Outdoor Unit Valve Leaks

Sometimes, the service valve near the compressor or indoor unit may leak. Our team can replace faulty valves and re-gas the unit immediately without needing to dismantle the entire system.

At LetsCool, we come equipped with all the tools and gauges required to diagnose and fix these common leaks right on-site, saving you time and hassle.

When Off-Site Repairs or Replacement May Be Needed

There are cases when an on-site fix isn’t feasible or cost-effective:

• Severe Pipe Corrosion Behind Walls or False Ceilings

  If the refrigerant pipe is embedded within walls or runs through false ceilings (common in condominiums), accessing and repairing it might not be possible without extensive hacking. In such cases, a full pipe replacement may be recommended, which requires more planning.

• Compressor or Condenser Coil Damage

  If the leak is inside the condenser coil or compressor, the part may need to be replaced. Depending on the model and warranty, this might involve a workshop repair or a manufacturer replacement.

• Multiple Leaks Across the System

  In older systems, multiple leaks may be present due to wear and tear. For these cases, we usually recommend a full overhaul or replacement, especially if the aircon is more than 8–10 years old.

What to Expect During a Gas Leak Service

At LetsCool Aircon and Services, we follow a step-by-step diagnostic and repair approach:

1. Site Inspection and Pressure Test

   We check for cooling performance and visible signs of gas leaks, and then conduct a pressure test using nitrogen gas to confirm the leak location.

2. Leak Detection

   Using tools like leak detectors and soap solution, we find the exact point of leakage.

3. Repair or Welding Work

   If the leak is accessible, we carry out on-the-spot welding, pipe patching, or flare joint replacement.

4. Vacuuming and Re-Gassing

   After sealing the leak, we vacuum the system to remove moisture and then recharge the refrigerant to the correct PSI.

5. System Testing

   We test the system under operation to ensure proper cooling is restored.
