Will UV HVAC Lights Really Increase the Air Quality in My Home?

UV germicidal lights connected to your home’s HVAC system can disinfect the air inside without using chemicals.

Indoor air quality (IAQ) is crucial to maintaining a healthy and comfortable living environment. With the increasing awareness of the importance of clean air, homeowners are exploring various technologies to enhance their IAQ. One such technology gaining popularity is using ultraviolet (UV) lights in HVAC systems.

Understanding How UV HVAC Lights Work

Mold and bacteria is a common concern when it comes to HVAC systems. According to the NCBI, fungal contamination often contributes to illnesses such as infectious diseases, asthma, allergic rhinitis, and hypersensitivity pneumonitis. However, UV lights have been proven to help eliminate many bacteria, germs, fungi, pathogens, and viruses. They can thus be used in a wide range of applications, including air purification.

Ultraviolet light is germicidal, which means it can break down the DNA in bacteria, viruses, and other airborne contaminants and thus keep them from growing. The UV light in the sun does this to the air outside. UV germicidal lights connected to your home’s HVAC system can disinfect the air inside without using chemicals.

There are two types of UV lights for HVAC systems:

  • Coil Sterilization – A UV light is installed inside the return air duct that sterilizes the air handler coil. It runs constantly and is the most common type of HVAC UV light.
  • Air Sterilization – This involves a complete Ultraviolet light unit that sterilizes moving air. It is installed in the return air duct and cycles with the air handler blower.

It is essential to understand that UV lights are a wise investment when installed correctly. That’s why you should hire a trusted HVAC technician to ensure the UV lights are put in the correct places and that the intensity and number of UV lamps are correct.
