As an expert in the HVAC industry, I have witnessed firsthand the numerous benefits of installing UV lights in air conditioning systems. These lights not only improve indoor air quality, but they also effectively kill harmful bacteria, viruses, and other contaminants that can cause odors or health problems. One of the most common types of UV lights used in HVAC systems is a duct light, strategically placed near the fan of the central air system to clean and disinfect all air passing through. The light is designed to turn on when no air is circulating and turns off to save energy when the heating or central air conditioning system is expelling air throughout the house.
And while there may be concerns about UV lights damaging materials, rest assured that they will not harm your air conditioning system. Another type of UV light used in HVAC systems is a disinfectant coil light, installed near the coil of the interior evaporator. To ensure maximum effectiveness, it is important to install the light as close to the center of the duct as possible. However, when researching these UV lights, I noticed that most information available was related to their effectiveness against COVID-19. But there are many other benefits to installing UV lights in your HVAC system that should not be overlooked.
One important factor to consider when deciding whether to install UV lights in your HVAC system is maintenance. Filters need to be replaced more often than bulbs in a UV light system, so it is important to stay on top of filter changes for maximum effectiveness. These lights are typically installed above the condensate tray, which collects moisture from the evaporator coil. It is also important to research and compare different UV light options before making a purchase.
Even if your HVAC system has a high-quality air filter, adding UV lights can provide an extra layer of protection against microorganisms and bacteria that may be small enough to pass through the filter. Not only do UV lights help maintain the best indoor air quality, but they also extend the life of your HVAC system by preventing dirt build-up and blockages. However, it is important to note that UV lights should not be seen as a replacement for other measures to improve indoor air quality. Regularly changing filters, keeping carpets clean, and monitoring humidity levels are all important steps to take before considering UV lights.
But if all else fails, adding UV lights to your HVAC system can provide an extra level of protection. When it comes to installation, the location of the light does not need to be precise, but it should be relatively centered on the return duct housing. Installing the light too close to the return filter can reduce its effectiveness. As for which type of UV light is best for your system, it ultimately depends on your specific needs and budget.
