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.

HDB Daikin Aircon Installation Job Scopes:

1. Site Inspection and Consultation

BCA-trained technicians conduct an on-site evaluation to determine the ideal location for the condensing unit, ensuring optimal airflow and compliance with HDB and BCA regulations.
The Homeone office team reviews the findings with the customer and outlines the relocation plan.

2. Dismantling

The existing condensing unit is carefully dismantled, including the safe disconnection of electrical connections and refrigerant lines.
All components are handled with care to prevent damage during the relocation.

3. Preparation

Bracket Installation: New brackets are installed at the selected location to securely support the condensing unit.
Refrigerant Pipe Preparation: Refrigerant pipes are measured, cut, and prepared to fit the new location accurately.
Trunking Preparation: Trunking is installed to protect and neatly organize the refrigerant pipes, ensuring a clean and professional appearance.

4. Installation

Condensing Unit Installation: The condensing unit is mounted on the newly installed brackets, ensuring stability and correct alignment.

Refrigerant Pipe Installation and Pipe Brazing: The prepared refrigerant pipes are installed and brazed to ensure airtight connections and optimal system performance.

Refrigerant Pipe Insulation Installation: Insulation is applied to the refrigerant pipes to prevent energy loss and protect against temperature fluctuations, enhancing system efficiency and longevity.
Use insulation tape and a gun for effective sealing and insulation.

5. Refrigerant Filling

Vacuuming: The system is first vacuumed to remove any dust, debris, or contaminants from the refrigerant lines, ensuring a clean and efficient system.
Charging: As specified on the manufacturer’s specification plate, the exact amount of refrigerant gas is then charged into the system to ensure optimal performance and efficiency.

6. Testing and Final Inspection

Gas Leak Detection Test: A comprehensive test is conducted to detect any gas leaks, ensuring all connections are secure and the system operates safely.
Temperature Analysis: The system analyzes temperature to verify efficient performance and accurate temperature levels.
A final inspection is performed to ensure compliance with HDB and BCA regulations, confirming that the installation meets all safety and technical standards.

7. Cleaning the Work Space

The work area is thoroughly cleaned after installation to remove any debris or materials left behind, ensuring the space is tidy and free of hazards.

8. Documentation and Submission

Homeone manages the preparation and submission of required documentation, including the HDB Aircon Installation Submission Form AC-02.
This ensures regulatory compliance and provides a hassle-free experience for the customer.
