Research Concludes the Effectiveness of Steam Cleaning of HVAC Coils

Research on heating ventilation and air conditioning (HVAC) systems has indicated that microbial contamination is an immediate problem when it concerns the indoor environment and human health. A study has been performed to determine the effectiveness of steam cleaning latent clogged debris from on or within evaporator coils of an HVAC that is restricting air flow, as well as causing poor air quality.

A dusty, rusty and clogged HVAC coil was treated with steam generated at 350ºC through a proprietary jet covering an area of 4’’ X 1” vertically at a time. Environmental bulk samples for microbiological (bacteria/fungi) evaluation were collected before and after steam sanitization from the front central face (fin) area of the coil. Light perforation and air flow tests of the coil were undertaken before and after the treatment.

The test results indicate that the steam cleaning is 99.99% effective in removing microbial contaminants and other surficial debris/lint. The light perforation, air flow, and static pressure tests reveal enhanced circulation, leading significantly towards optimal coil performance.
