Are you wondering how long a UV light for HVAC systems lasts? Most manufacturers recommend replacing the UV lamp every 9,000 hours or approximately every 12 months. This is also recommended for those with allergies and other respiratory conditions. UV bulbs usually last between one and two years, but the exact lifespan depends on the type of system and manufacturer's recommendations. To help you better understand how UV lamps work, here are some myths and facts about UV rays.
Some manufacturers offer UV-C lamps that are easily installed outside the air conditioning chamber and are suitable for residential and light commercial applications. If you ask your HVAC technician, they can provide specific instructions for your application. Additionally, consult the user manual or ask your Efficient AC, Electric & Plumbing technician for more information on the lifespan of UV bulbs. It's important to note that even if someone in your house coughs or sneezes, the UV light combined with the air conditioner will circulate the air and destroy any bacteria.
To ensure safety, it's recommended to place warning labels at access points to UV lamps or install electrical disconnection devices. UV lights are essential to destroy mold, mildew and other undesirable elements of the HVAC system. Not only do they eliminate organic matter on the surface of the coil and housing, but they also disinfect air that crosses its path. Research indicates that 99.9% of viruses and bacteria found in air ducts can be destroyed with UV light technology to improve air quality.
Installers must ensure that the size and location of the graphic window allow the UV system in operation to be seen from the outside of the air handler. Just by looking at the area of the ducts where the UV light is located, you can tell if it's still working.
