Most lamp manufacturers, such as Phillips, GE, and Sylvania, produce UV bulbs that need to be replaced at some point. The exact lifespan of a UV bulb will depend on the type of system and the manufacturer's recommendations. Generally speaking, a UV bulb will last between 1 and 5 years. A “blue tube” system bulb usually lasts 1 to 2 years, while the APCO or APCO X bulb is expected to last more than 3 to 5 years.
For example, it is recommended to replace a Carrier Coil UV lamp every 9000 operating hours or every year. In the case of a REME HALO, it is every 2 or 3 years and in a REME HALO LED, 4 to 5 years. You may need to replace the UV bulb first if it doesn't work properly or if you notice a decline in indoor air quality. Replacing light bulbs is an ongoing cost that you'll need to consider.
Your UV lamp can have one or two lamps, and each bulb should be changed every 6 to 12 months. If the UV or UV system is used seasonally (for example, for 6 months this year) and then it is drained and unplugged, you can use it for next year's season for another 6 months before having to replace the lamp with a replacement one. Since you spend up to 90% of your time indoors, it's important to consider the impact that pollutants can have on your long-term health and how UV lights in your air conditioning system can help. Several studies suggest that UV lights kill germs at high speed.
Unlike traditional UV disinfection systems that operate 24 hours a day, new automated systems emit UV light depending on the use of heating, ventilation and air conditioning systems. Air disinfectant lights are placed in the ventilation grilles, which are part of the ducts of your central air conditioning system. One study found that UV lights could reduce the amount of mold and bacteria in a test home by 97%. As air circulates around the house, it carries germs and allergens with it, which eventually pass through the ultraviolet light that disinfects the air as it recirculates around the house.
Ultraviolet (UV) lights are an effective way to improve indoor air quality by killing airborne bacteria and viruses. They are installed in air conditioning systems to help reduce allergens and other contaminants in your home. The lifespan of a UV light depends on several factors such as type of system, manufacturer's recommendations, and usage frequency. Generally speaking, a UV bulb will last between 1 and 5 years.
It is important to consider replacing your UV bulbs regularly in order to maintain optimal air quality in your home. Depending on the type of system you have installed, you may need to replace your bulbs every 6-12 months or every 1-5 years. If you are unsure about how often you should replace your bulbs, contact an HVAC professional for advice.

UV lights for air conditioning systems complement your air filtration system and provide an additional layer of protection.
