What is UV Technology?
UV (Ultraviolet) light is a type of electromagnetic radiation that is invisible to the human eye. It is present in sunlight and has a wavelength shorter than visible light, making it higher in energy. UV light can be categorized into three types: UV-A, UV-B, and UV-C.
UV-C light is the most powerful type of UV light and has germicidal properties that make it effective at killing bacteria, viruses, and other microorganisms. This is due to its ability to damage the DNA or RNA of these organisms, preventing them from reproducing and causing harm.
How Does UV Technology Work in HVAC Systems?
UV technology utilizes special lamps that emit UV-C light inside an HVAC system’s ductwork. These lamps are strategically placed near the evaporator coil, where moisture can accumulate and create a breeding ground for mold, bacteria, and other microorganisms.
When these organisms come into contact with UV-C light, their DNA or RNA is damaged, rendering them unable to reproduce and multiply. This stops them from spreading throughout the HVAC system and being recirculated into the air breathed in by occupants.
Disrupting Mold and Bacteria Growth with UV Lights
In addition to targeting the DNA of microorganisms, UV lights in Jacksonville, FL, are also powerful tools in disrupting their growth. This is because UV light can penetrate the cell walls of mold and bacteria, causing damage to their genetic material and preventing them from replicating.
By disrupting the growth of these harmful microorganisms, UV lights improve air quality and prevent potential health issues that can arise from exposure to mold and bacteria.
