What Are UV Germicidal Lights?

Nobody wants to have biological pollutants inside their ductwork, and the regular air filters in your AC are not effective at removing such contaminants. UV germicidal lights offer an innovative solution to eliminating these pollutants from your ducts. In this post, we’ll explain what these lights do and how they can help with improving the air quality within your home. If you want UV germicidal lights installed in your San Antonio, TX home, look to Cowboys Air Conditioning & Heating for quality, knowledgeable service.

The name “UV Germicidal Lights” sounds a bit intimidating, doesn’t it? It seems more like something you might find inside a laboratory rather than in your home. There is some truth to this: starting in the mid-20th century, UV germicidal lights were commonly used in laboratories and medical facilities to help create sterile environments. In fact, the man who pioneered their development, Danish scientist Niels Ryberg Finsen, won the 1903 Nobel Prize for Medicine because the UV lights could be used to kill the bacteria that caused tuberculosis.

But these powerful ultraviolet tools have started to enter residential homes to eliminate mold, fungus, and other biological pollutants that can form inside the dark and cool spaces in air conditioning ducts. An ultraviolet (UV) light is a mercury vapor lamp that that projects short wavelengths rays. These rays penetrate the cell walls of biological contaminants and disrupt their DNA, making it impossible for their cellular functions to continue working. This kills mold and bacteria and prevents them from spreading to cause further problems.

UV germicidal lights don’t just destroy the pollutants already growing inside your AC system. Their continual ultraviolet light also discourages the contaminants from returning, keeping your ducts clean and efficient and the air quality in your home at a healthy level. They also require very little maintenance—usually just an occasional bulb replacement.

Because UV germicidal lights are complex pieces of equipment, they require expert installation to make sure that they do their job properly and pose no risks to you and your family. Our San Antonio, TX professionals at Cowboys Air Conditioning & Heating specialize in installing UV germicidal lights so they will do their job efficiently.
