Air Conditioning FAQs

Q. What is biofilm?

A. Biofilm is any group of microorganisms in which cells stick to each other on a surface.

Q. What effect does Biofilm have on AC efficiency?

A. During normal AC processing air passes through dust filters prior to being cooled and introduced into the indoor environment. Dust filters act as the lungs of the system removing airborne particles from the air stream. However, even high grade dust filters cannot remove all airborne particulates. As airborne particles come in contact with moisture they colonize forming a biofilm over the cooling coil and other internal parts and surfaces. Biofilm blocks the airflow through the coil creating increased resistance to outgoing airflow. As a consequence, your system will require greater component output and energy demand for its normal operations. If left untreated, smells, leaks, warm air, component wear and tear or corrosion will result.

Q. Which Air Conditioning systems are at risk?

A. All. Even if the system is turned off. The moist, nutrient rich conditions within the system provide the ideal environment for biofilm growth.

Q. What kills biofilm?

A. Only remediation using multi-enzymatic treatment products can destroy the cellular structure on biofilm and protect your system from short term re-contamination.
