As an expert in the field of HVAC systems, I am often asked about the lifespan of UV lights in these systems. UV lights are a popular choice for air purification, as they use ultraviolet radiation to kill bacteria, viruses, and other harmful microorganisms. But just like any other product or service, UV lights have a limited lifespan and need to be replaced regularly. Most quality UV lamps will emit at least 80% of their original UV-C emission at the end of a year. This means that after 12 months, the effectiveness of the UV light will decrease by 20%.
This is why it is important to replace your UV bulbs every 6 to 12 months, depending on factors such as usage and system type. Generally speaking, the UV germicidal light used to disinfect indoor air must be replaced every 9000 hours, which is equivalent to approximately 12 months. However, if you or your family members suffer from allergies or asthma, it is crucial for your well-being to follow a plan to change your UV bulbs regularly. While some may worry about the potential damage that UV light can cause to materials, there is no need to worry about it damaging your air conditioning system. A poor installation can negate the purpose of installing a UV light, so it is important to hire a professional if you have any questions about how to complete the job. But once properly installed, UV lights require very little maintenance and only need care when they need to be cleaned or replaced. UV lights are typically installed in the air handler or return air duct of an HVAC system.
This allows them to clean the air in both the oven and central air system. If your UV lamp is installed in a vacation home or secondary residence where it is not used regularly, you can wait up to two years before replacing the bulbs. One of the most common types of HVAC lights is a duct light that is placed near the central air system fan. We recommend installing a UV light system specifically designed to disinfect the air in the return air duct of the air handler. The only downside to working with UV lights is that they can be dangerous, so it is important to hire a professional for installation or take proper safety precautions if you decide to do it yourself.
