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 in HDB Rental Flats, Mitsubishi System 3 at 56 Lengkok Bahru HDB on 25 Oct 2024

he homeowner of an HDB rental flat approached Homeone for an air-conditioning installation. We conducted a site assessment to determine the appropriate system, optimal positioning for the condenser unit, and the routing for the refrigerant piping.

Following the assessment, our Homeone engineering team reviewed the requirements and recommended installing a Mitsubishi System 3 split-type model, MXY-3H28VG, along with MSXY-FP20VG and MSXY-FP10VG indoor units. The Homeone management team then contacted the homeowner to present this solution, and, upon their approval, we commenced the installation.

The installation was carried out in compliance with BCA standards by our BCA-trained air-conditioning installers. The project was completed with the necessary Air-Conditioning Unit Installation Report for HDB Properties (Form AC-02).
