LMS Aircon is a Singapore-based aircon and M&E services company. Our technicians handle ducted aircon installation, repairs, replacements, and maintenance for a wide range of property types. We take the time to assess each job properly before recommending any work. That means you get an honest quote and a clear plan before anything starts.
LMS Aircon handles different repair needs for homes, offices, and commercial spaces. Our team checks each fault carefully before replacing parts. From cooling issues to electrical problems, we provide practical Aircon Fault Repair Singapore solutions based on the system condition.
Ducting installation sets up the network of channels that distribute conditioned air throughout a space. We handle full ACMV ducting installation for new builds and renovation projects, including layout planning, duct fabrication, and connection to your air handling units or fan coil units. Proper installation affects airflow balance, energy use, and long-term system reliability.
If your existing ducts are leaking, partially blocked, or physically damaged, targeted repairs can often fix the problem without a full replacement. Duct repair work includes sealing gaps, patching holes, fixing collapsed sections, and reconnecting loose joints. We identify the fault first, then repair only what needs attention.
When ducts are too old, heavily corroded, or poorly designed to fix efficiently, full aircon duct replacement makes more sense. We remove the old ductwork and install a properly sized system in its place. This is common during major renovations or when an older building upgrades its air conditioning setup.
Uninsulated ducts lose cooling energy as air travels through warm ceiling spaces. Insulation wraps around the duct surface to reduce heat gain and prevent condensation. This step is especially important in Singapore’s humid climate, where temperature differences between the duct interior and the surrounding ceiling air are significant.
Even small gaps in ductwork can cause noticeable cooling loss. Duct sealing closes off joints, connections, and small cracks using appropriate sealants or tape rated for HVAC use. It improves system efficiency and reduces energy waste without requiring duct replacement.
Exhaust duct installation applies to kitchen hoods, bathrooms, server rooms, and areas that need dedicated ventilation rather than air conditioning. We size and route exhaust ducts to meet the extraction requirements of the space, including connections to external discharge points.
Choosing an aircon repair team means trusting someone with your comfort and property. LMS Aircon focuses on proper checks, clear communication, and suitable repair steps. Our approach helps customers understand the issue before any work begins.
Leaking ducts reduce cooling efficiency and cause uneven temperatures across rooms. Leaks often develop at joints, bends, or connection points over time. We locate the source and seal it properly.
Weak or uneven airflow usually points to undersized ducts, blocked sections, or an imbalanced layout. We assess the duct network and identify where the restriction or imbalance is occurring.
Condensation forms when warm, humid air contacts a cold duct surface. This can drip into ceilings and cause staining or water damage. Proper insulation and sealing resolve most condensation issues.
Physical damage from renovation work, pests, or age can compromise the duct structure. We assess the extent of damage and recommend targeted repair or partial replacement.
Rattling, vibrating, or whistling sounds from ducts are usually caused by loose joints, improper support, or airflow turbulence from poorly designed bends. We trace the source and fix it.
Kitchen exhaust ducts accumulate grease over time, which creates a fire risk and reduces ventilation efficiency. Cleaning or replacing affected sections restores safe and effective operation.
HDB ducting work typically involves kitchen exhaust systems, bathroom ventilation, and ducted fan coil installations. Space is usually limited, so duct routing needs careful planning to keep runs short and efficient.
HDB ducting work typically involves kitchen exhaust systems, bathroom ventilation, and ducted fan coil installations. Space is usually limited, so duct routing needs careful planning to keep runs short and efficient.
Condominiums often have ducted systems for living and dining areas, with multiple fan coil units connected to a shared duct network. We handle both new installations and repairs in occupied units, working around the building's existing infrastructure.
Landed homes have more flexibility for duct routing but also require careful design to maintain consistent airflow across multiple levels and rooms. We assess the layout and plan a system that suits the property's size and cooling needs.
Offices, retail spaces, and F&B outlets often require more complex ACMV ducting layouts with multiple zones, different airflow rates, and integration with existing mechanical systems. We have experience working on commercial projects of varying sizes.
Galvanised iron (GI) ducts are the standard choice for most commercial and residential ACMV systems. They are rigid, durable, and suitable for long duct runs.
Pre-insulated ducts come with a built-in insulation layer, saving installation time and reducing the risk of condensation. They are commonly used in new builds and refurbishment projects.
Flexible ducts connect rigid duct sections to diffusers and grilles. They are useful in tight or awkward spaces but should be kept as short as possible to avoid airflow resistance.
These are designed for one-way air extraction from kitchens, toilets, and mechanical rooms. Material selection depends on the type of air being extracted standard ventilation uses different materials from kitchen exhaust work.

Ducting installation cost in Singapore depends on the size of the space, the type of ducting system, the number of connection points, and access conditions. A small residential job costs considerably less than a full commercial installation. We provide a written quote after a site visit.
The cost of duct repair depends on the type of fault and the extent of damage. Sealing a few joints costs less than replacing a damaged section. Contact us for an assessment and quote.
An aircon may need replacement when repairs become frequent, cooling performance drops, or the system becomes inefficient. Older units with major compressor or repeated faults may not be worth repairing. A technician can check the condition and suggest suitable options.
A complete ducting system cost varies based on duct type, property size, layout complexity, and whether insulation is included. Pre-insulated systems generally cost more upfront but reduce condensation risk. We’ll give you a clear breakdown after inspecting the site.
Yes. Most ductwork faults including leaks, loose joints, and minor physical damage can be repaired without replacing the whole system. Replacement is only recommended when the existing ducts are too old, corroded, or poorly designed to repair effectively.
Not always. Simple repairs like sealing joints or patching small holes are relatively affordable. Costs rise when sections need to be removed, rerouted, or replaced. Getting an assessment first gives you a clear idea of what’s involved.
