What are the signs of a refrigerant gas pipe leak in my air conditioner?

Common signs include decreased cooling efficiency after 1 to 3 days of the gas top-up, hissing or bubbling noises, ice formation on the refrigerant line, and an oily residue on or around the Aircon condenser unit.

What causes refrigerant gas pipe leaks in air conditioners?

Refrigerant gas pipe leaks in air conditioners can stem from several factors. Over time, wear and tear can compromise the integrity of the pipes, leading to leaks. Refrigerant gas pipe leaks can result from improper chemical washing of air conditioners. Harsh or incorrect cleaning agents can corrode the pipes and connections, leading to leaks. Additionally, inadequate rinsing can leave residues that accelerate wear and tear. Factory defects and improper installation can result in weak points that eventually give way. Physical damage to the refrigerant lines, whether from accidental impacts or environmental factors, can also cause leaks. Additionally, the constant vibration of the air conditioner can gradually loosen joints, creating gaps through which the refrigerant gas can escape.

Can I fix aircon gas leak myself?

It is not recommended to fix a refrigerant leak yourself. Refrigerant handling requires special tools (eg., pressure gauge, refrigerant scale, etc) and certification due to the hazardous nature of the chemicals. It’s best to contact a BCA Trained Installer.

How can I prevent refrigerant leaks in my air conditioner?

Proper Chemical Washing: Use appropriate, mild cleaning agents and ensure thorough rinsing to prevent corrosion and residue build-up that can damage refrigerant pipes and connections. Regular Maintenance: Schedule regular professional maintenance to check and clean all components, ensuring no build-up or damage that could lead to leaks.

How much does it cost to repair a refrigerant gas pipe leak?

The cost to repair a refrigerant gas pipe leak varies depending on the leak’s severity, location, and refrigerant type. Typically, it ranges from $350 to $600, including our BCA-licensed installers’ fees and refrigerant refill. Our pricing covers all necessary submissions, ensuring repairs are conducted by certified air-conditioning unit installers as mandated by the Building and Construction Authority.

How long does it take to repair a refrigerant leak?

The time required to repair a refrigerant leak can vary depending on the location and severity of the leak. Minor leaks might take 2 hours to fix, while more severe or difficult-to-access leaks could take 4 hours.

Aircon Installation for Private Property Job Scopes:

1. Site Inspection and Planning

Our team conducts a thorough on-site inspection to assess the existing setup and determine optimal placement for the new units.
This stage ensures compliance with property regulations and identifies potential challenges in installation.

2. Removing the Existing Aircon System

We carefully bring down the current Mitsubishi cassette air conditioning system, including both the outdoor and indoor units.
This step is crucial to prepare the space for the new installation and to ensure safe removal without causing damage to the structure.

3. Flushing the Refrigerant Pipe

Since the previous system used R410A refrigerant and the new one will use R32, a thorough flushing of the existing refrigerant pipes is carried out.
This process guarantees that no contaminants remain, ensuring optimal system performance and longevity.

4. Mounting the Indoor Unit

The new indoor Mitsubishi cassette unit is securely mounted in the existing location.
Proper alignment and stability are checked to avoid any future performance issues or unnecessary wear.

5. Installing the Outdoor Unit

The new outdoor unit is installed with precision, ensuring proper airflow and accessibility for maintenance.
It is securely mounted to withstand environmental factors while maintaining compliance with property standards.

6. Connecting the Electrical Wires

All electrical connections are carefully made, following safety standards.
Our technicians ensure that wiring is secure and correctly configured to provide reliable power and control to the system.

7. Vacuuming the Refrigerant Line

After ensuring the refrigerant line is clear, the system is vacuumed to remove any remaining air and moisture.

8. Testing the System

Once installed, the entire system undergoes a series of tests to ensure it is functioning optimally.
Cooling performance, electrical safety, and pressure readings are verified to ensure all components are operating smoothly.

9. Documentation and Cleanup

Upon completion, we provide all necessary documentation, including warranty papers and BCA compliance forms.
The work site is thoroughly cleaned, leaving your property tidy and ready to enjoy your new air conditioning system.
