As an expert in the HVAC industry, I have seen firsthand the advantages of incorporating UV light purifiers into homes. These devices utilize ultraviolet (UV) light technology to enhance air quality by eliminating 99.9% of viruses and bacteria found in air ducts. However, like any other technology, UV bulbs have a limited lifespan and must be replaced regularly for optimal effectiveness. Most lamp manufacturers, such as Phillips, GE, and Sylvania, recommend replacing UV bulbs every three years, regardless of usage. This is because the performance of the UV lamp deteriorates over time due to the buildup of incrustation and solorization.
Solorization is a condition in which the quartz material of the lamp discolors, reducing the intensity of the UV light. This affects both the lamp material and the quartz cover, resulting in a decrease of approximately 40-60% in UV ray intensity after just over a year of operation. To ensure optimal performance, experts suggest replacing UV bulbs every 9-12 months. However, this may vary depending on the type of system and manufacturer's recommendations. To determine if your UV bulb needs to be replaced, simply check the area of the ducts where the lamp is located.
If you notice a decrease in blue light or if the bulb appears discolored, it's time for a replacement. At Sansone, we offer a variety of services for your HVAC system, including installation and maintenance of UV lamps. Our team of experts can provide you with specific instructions on how to check your UV bulb during installation or maintenance appointments. Some UV systems also have a ballast or controller that will indicate when it's time to change the lamp. One common misconception about UV lamps is that they consume a lot of electricity. In reality, they require a very low amount of electricity, making it best to leave the UV water filter system turned on even when water is not passing through it. In addition to improving air quality, UV lamps also offer many other benefits for your home.
They are a great addition to your HVAC system as they can help reduce mold and mildew growth, eliminate unpleasant odors, and improve overall indoor air quality.
