As an expert in the HVAC industry, I have seen firsthand the benefits of using ultraviolet (UV) lights to improve indoor air quality. These lights are designed to kill bacteria, mold, and other harmful contaminants that can circulate through your home's air. However, many people are unaware that these lights have a limited lifespan and need to be replaced regularly to maintain their effectiveness. Most manufacturers recommend replacing UV lamps every 9000 hours or approximately every 12 months.
This is because after a year of use, the light's ability to kill bacteria will slowly decrease, leaving your family vulnerable to potential health risks. For those with allergies or respiratory conditions, it is even more crucial to follow a regular replacement program. Typically, a UV lamp will last for 12 months or about 9000 hours of use. However, this can vary depending on factors such as how often the system is used and how it is used.
Some high-end UV systems may last up to two years, but it is always best to check the manual for specific recommendations. If you only use your UV system seasonally, for example, for six months out of the year, you can use it for another six months the following year before needing to replace the light. However, if you cannot replace the light after two years, it is essential to turn off or disconnect the power supply until it can be replaced. It is crucial to note that UV lights must always be on to be effective.
If they are turned off or lose their effectiveness over time, they will need to be replaced at least once a year. Poor installation can also hinder the purpose of installing a UV lamp, so it is best to hire a professional if you have any questions or concerns. UV lights are most effective when directed at condensers, coils, and other areas where moisture can accumulate and light can continuously shine. At Scott's Heating & Air Conditioning, we recommend using UV lights in these areas to prevent mold and bacteria from accumulating and circulating through your home's air.
While UV lights may not be visible to the human eye, several studies have shown that they are highly effective at killing germs. When it comes to choosing the right UV light for your HVAC system, it is essential to consider the system and your specific needs. There are two main types of UV lights for HVAC systems: coil sanitizer lights and air sanitizer lights. Coil sanitizer lights are great for keeping the system clean, while air sanitizer lights are best for cleaning the air itself.
Like any air purification product or service, UV lights are not invincible and can become damaged over time. It is crucial to follow an annual replacement program to ensure that your UV lights continue to keep your indoor air healthy. Not only do these lights improve indoor air quality, but they also help maintain the functionality of your HVAC system.
