How Long Do UV Lights Last in HVAC Systems? - An Expert's Guide

Most quality UV lamps will emit at least 80% of their original UV-C emission within a year, making it necessary to replace the bulbs on a regular basis. Depending on how often you use the system and other factors, the bulbs should be changed every 6 to 12 months. Generally speaking, a UV germicidal light used to disinfect indoor air must be replaced every 9000 hours, which is approximately 12 months. If you or your family members suffer from allergies or asthma, it's essential to follow a regularly scheduled UV bulb change plan.

Mounting UV lights to all ducts in the system is not recommended, as it requires more work and can defeat the purpose of installing a UV lamp. It's best to hire a professional if you have questions about how to complete the job. For most UV disinfection systems, complying with an annual replacement program will ensure that ultraviolet lights continue to keep indoor air in the house healthy. Automated systems emit UV light depending on the use of heating, ventilation and air conditioning systems.

To install a UV light system, plug it into a nearby power outlet with an extension cord with the appropriate rating. The HVAC UV lamp helps you stay healthy by disinfecting the air that circulates through the air conditioning system and reducing the distribution of mold and viruses in the air in your home. This type of lamp is ideal for residential air conditioning systems because it is affordable, easy to install and disinfects the air when the air conditioner or oven is running. Even if your air conditioning system has a high-quality air filter, adding a UV light will help eliminate microorganisms and bacteria that might be small enough to pass through the filter.

A final advantage of installing UV-C lamps in the air conditioning system is that they also destroy volatile organic compounds (VOCs), which cause unpleasant odors reminiscent of tobacco smoke. While it's true that UV light can damage some materials, you don't have to worry about a UV lamp damaging your air conditioning system. Installing a UV light system in your HVAC system is an effective way to keep your home's air clean and free from harmful bacteria and viruses. It's important to remember that these lamps need to be replaced regularly in order for them to remain effective.

Most experts recommend replacing them every 6-12 months or after 9000 hours of use. This will ensure that your home's air remains clean and healthy for you and your family.
