Air System International Ltd has proven time and again that it delivers top quality plumbing services in all settings, from domestic buildings to office blocks and all else in between.

Plumbing is a core part of HVAC services. While everyone nowadays is aware of the need for reliable plumbing, many people don’t stop to appreciate what a difference the professionalism during the installation process makes.

The truth is that the quality of installation should be a very real concern – plumbing is a complicated and tricky business, especially considering that you need to make sure not only that everything works, but that your pipes and valves are quiet and leak-free.

Plumbing systems carry out a number of essential and major functions – they are responsible for the majority of your heating and cooling, waste removal, and potable water delivery, as well as plenty of other applications. That’s why you should rest assured when choosing a plumbing supplier that the company you’ve turned to can be trusted to deliver secure and reliable results. That’s where ASIL comes in.

Indeed, ASIL strives to make sure the installation process is precise and meticulous, so that maintaining your plumbing afterwards will be as easy as can be. We also take measures to be as efficient and economical as can be during the work process itself, to make sure that we deliver high quality results without overcharging or wasting any of your money. We do not waste material and we do not carry out weak framing that will have to be fixed later on. We also make sure all joints are clean and in top form when installing them to keep them durable.

The materials ASIL uses in plumbing installations are up-to-date with the most current and internationally tested standards. Because of this, our plumbing systems are modern, cost-effective, and sturdy. Our solutions can and will be tailor-made for your needs, so do inquire about what kind of piping would work for you best.

Our pipes are mostly made of plastic (including a number of varieties such as PVC and PEX) and, on a lesser level, metals (mainly copper). If you’re unsure of why we opt for these materials and what the difference between them is, allow us to explain:

Plastic (PVC, ABS, PEX, etc.)

For many decades now, plastic has become the dominant material in piping and tubing production for domestic water supply and drain-waste-venting. It’s not hard to imagine why – plastic is extremely cost-effective without compromising the sturdiness you’d expect from other materials. Polyvinyl Chloride (PVC) piping actually began to show its value post-WWII, when the infrastructures of Germany and Japan had to be rebuilt. Other types of plastic adequate for piping came to fruition not long after that, including acrylonitrile butadiene styrene (ABS) and cross-linked polyethylene (PEX).


Although plastic materials have taken lead over metal ones when it comes to plumbing installation, this is mostly due to cost reasons. Copper is still a great option for piping in domestic and non-domestic settings alike.
