Most lamp manufacturers, such as Phillips, GE, and Sylvania, produce quality lamps that emit at least 80% of their original UV-C emission within a year. However, 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.
When the boiler or central air conditioning system blows air through the house, the HVAC UV light will turn on when no air is circulating and turn off to save energy. This light has germicidal properties, making it ideal for disinfecting air as it passes through the air conditioning system. It is also beneficial in limiting mold growth throughout the HVAC system and preventing certain respiratory diseases. Even if your air conditioning system has a high-quality air filter, adding a UV light will help eliminate microorganisms and bacteria that might be small enough to pass through the filter.
Before you start drilling, be sure to check and recheck the instructions that came with the UV lamp. Filters need to be replaced more often than bulbs in a UV light system, making them difficult to maintain and reducing their effectiveness if you forget to change the filter. To ensure your HVAC UV light is working properly, we recommend adding a reminder to replace it to your list of maintenance tasks for your heating, ventilation and air conditioning system. UV lights are highly effective in eliminating airborne pathogens that infiltrate your home's heating and cooling system.
We suggest installing a UV light system designed to disinfect the air in the return air duct of the air treatment unit. Alternatively, plug the UV light into a nearby power outlet with an extension cord with the appropriate rating. If you're concerned about indoor air quality, consider installing an ultraviolet (UV) light in your air conditioning system. This will help keep your home's air clean and safe from harmful microorganisms and bacteria.
To ensure your HVAC UV light is working optimally, it is important to replace it regularly. Most lamp manufacturers recommend replacing bulbs every 1-5 years depending on the type of system and manufacturer's recommendations. We suggest adding a reminder to your list of maintenance tasks for your heating, ventilation and air conditioning system so you don't forget to replace it.
