Most quality lamps will emit at least 80% of their original UV-C emission at the end of a year. Replacement bulbs are an ongoing cost that you'll have to consider. The UV lamp can have one or two lamps, and each bulb must be changed every 6 to 12 months. This will depend on a few factors, such as how you use the system and how often you use it. Generally speaking, a germicidal UV light used to disinfect indoor air should be replaced every 9000 hours.
This equates to approximately 12 months. If you or your family members suffer from allergies or asthma, maintaining a regularly scheduled UV bulb replacement plan is absolutely essential to your well-being. The only downside is that working with UV lights can be dangerous, so you'll have to hire a professional to install them or take some safety precautions if you decide to do it yourself. This means that when the boiler or central air conditioning system blows air through the house, the UV light will turn on when there is no air circulation and will be turned off to save energy.
By preventing mold and bacteria from accumulating in the wet components of the HVAC, UV lights can also prevent airborne biological contaminants from circulating in the indoor air of your Orlando home. If you can't replace the UV lamp after a period of two years, turn it off or disconnect the power supply until you change it. The metal used in most ducts in air conditioning systems is resistant to damage caused by UV rays and does not wear out or become brittle over time, such as plastic or other composite materials. Mounting it this way will allow UV light to clean the air in your oven and your central air system, if you have one.
Once installed, UV lights require very little maintenance and only need attention when they need to be cleaned or replaced. We recommend that you add a reminder to replace UV light to your air conditioning maintenance checklist, so you don't forget it. The most common type of HVAC light is a duct light that is placed near the central air system fan. UV light has germicidal properties, making it ideal for disinfecting air passing through the HVAC system.
The location of the hole doesn't have to be precise, but make sure it's relatively centered on the return duct housing; you don't want to install the light too close to the return filter.

While their cleansing power is not visible to the human eye, several studies suggest that UV lights kill germs at a high rate. For most UV disinfection systems, maintaining an annual replacement program will ensure that ultraviolet lights continue to keep your home's indoor air healthy.
