How Do UV Lights In HVAC Work? getrotation.com/how-do-uv-lights-in-hvac-work By Vitaly Stotland
Your home or office building’s HVAC technician can inquire if you’d be open to placing ultraviolet (UV) lamps inside your system. Certain UV lamps can lessen or stop the circulation of microbes in your home’s or office’s ductwork. This article discusses the details of how specific UV lamps can carry out this work and responds to some of the most often asked queries regarding UV lights’ ability to clean HVAC systems.
How Does UV Radiation Work? Ultraviolet light waves fall in the range of 0 to 400 nanometers (nm) in the light spectrum. Nanometers, or billionths of a meter, are what the letter nm stands for. The human eye is optically blind to this range. Contact us if you are looking for HVAC Cleaning Duluth GA. There are four levels1 in the 0 to 400 nm spectrum, and they are as follows: Firstly, the most prevalent form of ultraviolet radiation in the sunshine, UV-A (longwave; 400 to 315 nm), causes skin tanning and wrinkling. Secondly, skin reddening and skin cancer are predominantly caused by UV-B (medium-wave; 315 to 280 nm). Thirdly, the most efficient germicidal control wavelength is UV-C (short-wave; 280 to 200 nm). UV radiation below 200 nm (vacuum UV; 0 to 200 nm) can cause the air to become ozone-filled (O3). Lastly, the portion of the UV-C spectrum that exerts germicidal effects is at 253.7 nanometers, where DNA is best able to absorb UV radiation.
Are Bacteria and Viruses in My HVAC System a Health Risk? According to science, bacteria and viruses can pose a serious threat to human health. HVAC unit contamination is a common problem which you shouldn’t disregard. According to the National Institute of Health, this contamination frequently plays a role in building-related illnesses such as viral or bacterial infections, allergic rhinitis, asthma, hypersensitivity, and pneumonitis. However, you can use only specific UV lights to purify the air. Moreover, you can eliminate numerous kinds of bacteria and viruses with the aid of ultraviolet germicidal light (UVGi). The UV-C spectrum, which is the most effective wavelength spectrum for germicidal effectiveness, is where the UVGi light acts.
Does Using UV Lights Improve the Air Quality in My Home?

UV light can improve the air quality. However, it depends on how appropriately you place them while using the correct UV light spectrum. The homeowner is responsible for making sure the installation is done correctly by a licensed HVAC expert and that the environment is suitable. When installing a system, a skilled individual with knowledge of UVGi systems must consider several considerations. The correct number and positioning of UVGi lamps highly influence the Effectiveness. Moreover, indoor humidity and temperature also play their role in it.
How Does Air filtration Work Absolutely. The CDC advises using an air filter with a High-Efficiency Particulate Air (HEPA) rating to capture bigger particulates. It is crucial because particles can protect microorganisms from UV light irradiation. The CDC advises utilizing Ultraviolet Germicidal Irradiation (UVGI) as a supplement to HEPA filtration because it cannot completely replace it.
Which System Types Are Available? There are two types of UV light installations for HVAC systems: coil sterilization and air sterilization. An in-duct UVC system, also known as air sterilization, uses UV-C radiation to cleanse the air as it circulates through the return ducts. The efficiency of the UV-C light is increased by improving the reflecting surface within that portion of the ductwork, which maximizes UV-C light in all directions. Coil sterilization involves installing UV-C lamps to target delicate and prone-to-issue components such as cooling coils, condensation pans, and filters. It makes it possible to focus microbial growth in hard-toreach places like grooves, fins, seams, and edges. Therefore, contact us for dryer vent cleaning Duluth.
Is It Expensive To Run An HVAC UV Light System? After installation, your UV-C system will incur costs for electrical usage and bulb replacement. A Watts-to-Power Cost Calculator and an Amps-to-Watts calculator can be used to estimate the amount of electricity consumed. Amps/Watts are typically listed on the UV-C bulb and in the installation’s operator’s manual.
Warning About UV Light Safety We are all aware of the cautions from common sense regarding excessive sun exposure, which can result in skin damage and, in some circumstances, skin cancer. Direct UV-C exposure from HVAC systems is dangerous, especially for the skin and eyes. Eye injury can be severe and occasionally permanent. Thus expert installation and handling are necessary. A trained expert will take the required safety measures during installation to make sure that no UV-C light ever gets into a building’s occupants’ eyes.

Proper air filtering is the first line of defense against the spread of germs within your HVAC system. UV lamps have a high potential for eradicating bacteria, mold, and viruses under the appropriate circumstances and with a suitable installation. Together, the two can create a much healthier environment in your house or place of business.
