Taking proper care of your HVAC piping is an important responsibility for every homeowner. Your HVAC system is responsible for transporting both hot and cooled water, as well as refrigerant, gas, and steam, around your property. Understanding what the different pipes do and why different materials are used for each can help you to ensure that your system is operating as it should be. Your HVAC piping is essential for connecting all of the components of your HVAC system and will be made from a variety of materials depending on the function of each pipe. An understanding of the different pipes will allow you to better diagnose problems with your system and ensure that any HVAC engineer you call is using the correct materials to maintain your system.

Plastic HVAC piping

If you have plastic piping in your HVAC system, it probably forms part of the vent piping system. Plastic is especially popular for underground piping since some soils can be corrosive and quickly cause damage to metal piping. If metal piping is used below ground, it is often covered by a PVC plastic sheath for protection.

Copper HVAC piping

Copper is one of the most widely used types of piping in HVAC systems. Copper piping can be used for carrying all temperatures of water as well as both compressed air and refrigerant. Copper piping is also commonly used for transporting condensate drainage.

Steel HVAC piping

Large HVAC piping is often made from steel since steel pipes can accommodate a range of pressures and temperatures without a problem. Steel pipes can be produced in a range of thicknesses to accommodate the variety of HVAC uses. In your HVAC system, you could find that steel piping is used for almost anything, including for moving hot or chilled water or for process cooling purposes. Galvanised steel HVAC pipes can be employed for transporting fuel oil, transporting steam or transferring condensate or condensate return.
