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