As an expert in the HVAC industry, I have seen firsthand the benefits that UV lights can provide in homes. These lights, when installed in HVAC and water purification systems, can prevent mold and bacteria from accumulating in moist components and circulating through the indoor air. However, to reap these benefits, it is crucial to regularly change the UV bulbs. At Scott's Heating & Air Conditioning, we recommend replacing all UV bulbs every three years, regardless of how often they are used. This ensures that the UV lights continue to keep the indoor air in your home healthy.
Even if your UV lamp is installed in a vacation home or other secondary residence where it isn't used regularly, it is still important to change the bulbs every three years. But why is it necessary to change the bulbs so frequently? The answer lies in the limited lifespan of UV lights. Just like regular bulbs, UV lights also have a limited lifespan and need to be replaced regularly. If you don't change a burned out UV bulb, you won't be able to take advantage of the benefits that UV light can provide in your home. So, how do you know when it's time to change the bulbs? The most specific instructions for your application can be provided by your HVAC technician during installation or maintenance appointments. However, a general rule of thumb is to check the area of the ducts where the UV light is located.
If the bulb is still working, you will be able to tell just by looking at it. For most UV disinfection systems, following an annual replacement program will ensure that the UV lights continue to keep your indoor air healthy. Research has shown that 99.9% of viruses and bacteria in air ducts can be destroyed with ultraviolet light technology, improving the overall air quality in your home. But what happens after the UV light is installed? How often do UV bulbs need to be changed? These are common questions that homeowners have. As mentioned earlier, it is recommended to change the bulbs every three years. However, if you notice any issues with your HVAC system or a decrease in air quality, it may be necessary to change the bulbs more frequently. In conclusion, as an expert in the HVAC industry, I cannot stress enough the importance of regularly changing UV bulbs in your AC unit.
Not only does it ensure that you are reaping the benefits of UV light technology, but it also helps maintain a healthy indoor air quality for you and your family. So, make sure to mark your calendar and schedule regular bulb changes to keep your home's air clean and healthy.
