Uv Light In Hvac Effectiveness

There are a couple different set ups for the uv lights in the hvac system.

Uv light in hvac effectiveness.

The uvgi light operates within the uv c spectrum which is the effective wavelength spectrum for germicidal efficiency. The ultraviolet germicidal light uvgi can help eliminate many types of bacteria and viruses. Also if your hvac system has damaged or leaky ducts the vacuum created in the ducts could draw in new contaminates from attics and crawl spaces limiting the uv light effectiveness. When properly installed and maintained within an hvac system uv lights increase the quality of air in buildings.

Ultraviolet lights specifically germicidal uvc. Experts believe that improvements to hvac units and the addition of uv lights at the office or at the home can help in the fight against covid 19. In most residential cases an hvac company will install the uv light near the coils to prevent mold or bacteria growth as air passes through. Uv lights for your hvac will not alleviate your symptoms caused by allergens since dust as well as dead fungi will still be present.

Uv lights are in the news because of the pandemic but the technology is over 100 years old. Since all of the air passes through the coils this also kills growths in the air. Uv lights are particularly effective in humid climates where evaporator coils can easily get wet. Shortwave radiation uv c is emitted from these systems and is most effective at killing mold bacteria and viruses.
