Services Solution
More Than Just Water Heaters
Multi-Trade Services You Can Rely On
AOT also offers expert plumbing services, pump systems, pressure vessels, air conditioning maintenance, and general upkeep like minor ceiling works — all delivered with the same reliability and care we’re known for.
We also carry out sanitary ware installations — including toilets, sinks, bathtubs, bidets, and more — with precise leveling, sealing, and alignment to prevent leaks and ensure proper drainage. Whether it’s a new home, renovation, or commercial fit-out, we make sure your bathroom fittings are secure, functional, and professionally installed.
Our expertise extends to water heater installations, covering both instant heaters, which provide quick hot water for light use, and storage heaters, ideal for families or larger properties with multi-point access. Every installation is carried out by licensed technicians following safety standards and optimal pipe routing to ensure performance and longevity.
Plumbing Services
Our team handles complete plumbing solutions, from small repairs to full-scale system installations. We work with various pipe materials including PVC, known for its cost-effectiveness and corrosion resistance; copper, valued for its durability and long lifespan; and stainless steel (SS), ideal for high-rise buildings or areas with high water pressure due to its strength and hygiene.
Pump & Water System Services
Water pressure is essential for modern living — and we ensure it remains consistent and reliable. We supply, install, and replace domestic and commercial water pumps suited for various building types and pressure demands. Whether you're dealing with poor water flow or setting up a new system, our tailored pump solutions keep your water moving efficiently.
Our pressure vessel services help regulate and stabilize water pressure, reducing system strain and extending pump life. We ensure that vessels are properly sized and correctly installed, improving energy efficiency and reducing noise and vibration in the system.
We also offer water tank washing and maintenance, a service often overlooked but critical for maintaining water hygiene. Over time, sediment, algae, and bacteria can accumulate in water tanks. Our team performs thorough cleaning and disinfection, complying with Singapore’s health and safety standards — an important service for HDBs, condos, food premises, and healthcare facilities.
Air Conditioning & Cooling Services
Our air conditioning services focus on keeping your system clean, efficient, and long-lasting. We perform chemical cleaning, filter servicing, coil and blower maintenance, and gas top-ups, all of which reduce your energy bills and improve air quality. Our regular servicing packages are popular among households and offices looking to avoid breakdowns during peak usage.
For larger properties, we provide chiller system maintenance — essential for commercial and industrial buildings with centralized cooling. We inspect chiller units, check refrigerant levels, clean condenser coils, and ensure the system is running at peak efficiency. This reduces unexpected shutdowns, improves cooling capacity, and extends system life.
General Maintenance
In addition to M&E (Mechanical & Electrical) systems, we offer minor general maintenance, including false ceiling works. After plumbing, pump, or aircon servicing that involves accessing ceiling spaces, we provide proper patch-up, repair, or repainting services, ensuring a clean and professional finish.
We understand that small issues like ceiling cracks or stains can impact a property’s appearance and even affect tenant satisfaction. Our team ensures quick, quality repairs that restore the aesthetics and integrity of the ceiling — especially important in retail, residential, and hospitality environments.
