Although steam cleaning is one of the trends when it comes to cleaning HVAC systems, the question is whether it is effective enough or not? Industry representatives have a mixed opinion on the subject.

Highlighting the benefits of steam cleaning of HVAC systems, Meraj Asad Khan, Sales & Product Head of Retail Sales Channels (UAE) at Karcher, said: “Steam is pure, and it condenses into simple water and not only cleans but sanitises the HVAC equipment, as well. The main benefit is that it is healthier than using chemicals, which have harmful effects. It is also known to have a low impact on the environment.”

Differing from Khan’s view, Leo Radford, Managing Director of Envida Technical Services, said: “If using steam cleaning process, it depends on which components of the system need cleaning. Components like coils and filter racks can be steam cleaned, and it is more economical than environmental friendly.

“Steam should never be used for cleaning of ducts; rather, dry cleaning methods need to be adapted, as prescribed by the National Air Duct Cleaners Association (NADCA) standards, because steam cleaning can invite moisture and mould problems.”

Radford further added that it is important to have periodical cleaning of equipment rather than once every few years.
