Leaky duct repair services

Leaky Duct Repair Services by EKG M&E Sdn Bhd

In the 2026 Malaysian regulatory landscape, Leaky Duct Repair has transitioned from a routine maintenance task to a mandatory requirement for EECA 2024 compliance. In Kuala Lumpur and Selangor, where HVAC systems typically consume over 50% of a building's total energy, air leaks represent a significant financial drain and a risk to your Building Energy Index (BEI).

At EKG M&E Sdn Bhd, we provide specialized repair services that ensure your air distribution reaches Airtightness Class 6 (ATC 6), the 2026 gold standard for energy-efficient assets.

1. Diagnostic Detection: Locating the "Hidden" Waste

Before any repair, we establish a precise leakage profile using advanced diagnostic tools:

• Ultrasonic Leak Detection: Identifying high-frequency sound waves emitted by pressurized air escaping from microscopic gaps.

• Theatrical Smoke Testing: Injecting non-toxic smoke into isolated duct sections to visually confirm joint failures and structural cracks.

• Duct Leakage Testing (DLT): Using calibrated fans to measure the exact liters per second ($L/s$) lost, providing the baseline data required for official Suruhanjaya Tenaga (ST) energy audits.

2. Specialized Repair & Sealing Methodologies

We utilize a tiered approach depending on the accessibility and pressure class of the ductwork:

A. Aerosolized "Inside-Out" Sealing

For existing buildings where ducts are buried behind fixed ceilings or within narrow shafts.

• Zero Demolition: A computerized system injects a vinyl acetate polymer mist into the pressurized air path.

• Targeted Bonding: The particles bond to the edges of leaks up to 15mm, sealing the entire network from the inside out without disrupting office operations.

B. High-Velocity Fiber-Reinforced Mastic

For visible joints, main headers, and AHU discharge sections.

• Tropical Resilience: We use mastics formulated to remain flexible in Malaysia's high humidity (80%-90%), preventing the cracking and peeling common with legacy duct tapes.

• Structural Bridge: For larger gaps, we embed a fiberglass mesh into the mastic to create a permanent, hermetic bond.

C. Flange & Gasket Refurbishment

• TDC/TDF Joints: Replacing degraded gaskets with high-performance, closed-cell elastomeric seals to ensure metal-to-metal airtightness on main distribution lines.

3. Critical Operational & Compliance Benefits

• TNB Maximum Demand Reduction: By eliminating leaks, your Variable Frequency Drives (VFDs) can run at lower frequencies ($Hz$) while delivering the same cooling, slashing your monthly peak demand charges.

• EECA 2024 Star Rating: Professional repair is the fastest route to securing a 4-Star or 5-Star Energy Intensity Label.

• DOSH IAQ 2026 Compliance: Sealed return ducts prevent "plenum aspiration" (the suction of dusty, mold-prone air from ceiling voids), ensuring you pass mandatory bacterial and fungal ceiling audits.
