How Do UV Germicidal Lights Work?

Friday, July 11th, 2014

Sunlight has long been known to kill problematic organisms such as mold and mildew. But there are several different types of light that emit from the sun, and each type of ray has its own effect on organisms. UV light, also known as ultraviolet light, is actually a type of electromagnetic radiation that can help eliminate germs entirely without the side effects of harsh chemical disinfectants. So how can UV germicidal lights help your air conditioner in San Antonio? It’s in the nature of how the lights work.

What Is UV Germicidal Light?

As mentioned above, UV light is electromagnetic radiation from the sun; the most harmful UV rays are screened out by the Earth’s atmosphere. UV light is divided into 3 classifications: UV-A, UV-B and UV-C. Each can damage organisms, but it is the UV-C light that is classified as “germicidal”.

How Do UV Germicidal Lights Work?

UV-C light can destroy a great number of microorganisms, including viruses, bacteria, mold spores and allergens. It irrevocably damages the organism’s DNA. The damage caused by the UV-C light destroys the organism’s ability to both replicate and create life-sustaining proteins. The end result is that the organism can no longer reproduce or survive.

Benefits of UV Germicidal Lights 

  • Kills germs
  • Helps eliminate odors
  • Stops mold and bacteria growth
  • Destroys volatile organic compounds
  • Generates negative hydroxyl ions


UV germicidal lights can be placed different areas of your air conditioning system:

  • Over evaporator coils
  • Inside air ducts

When placed over the evaporator coils in your system, UV germicidal lights eliminate growths like mold, mildew, algae and gel formations. In your ductwork, microbes like bacteria, viruses and allergens are destroyed before they can enter through the vents.

Ready to Shine Some Light on Germs?

UV germicidal lights kill over 99% of micro-organisms. If you have concerns about germs, mold growth, bacteria and allergens, it may be time to consider what a UV germicidal light can do for your home.

What Are UV Germicidal Lights?

Monday, September 9th, 2013

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.
