As an expert in the HVAC industry, I have seen firsthand the impact that UV lights can have on improving indoor air quality. These lights are a popular choice for homeowners looking to reduce allergies, prevent illness, and protect their loved ones. However, there are some important factors to consider before installing UV lights in your residential HVAC system. First and foremost, it's crucial to understand that working with UV lights can be dangerous. It's highly recommended to hire a professional for installation or take proper safety precautions if you decide to do it yourself.
This is not a DIY project to take lightly. So, how exactly do UV lights work in an HVAC system? When the heating or central air conditioning system expels air through the house, the UV light will turn on when there is no air circulation and turn off to save energy. This means that the UV light will clean the air in the heating and central air system, if you have one. It's worth noting that UV filtration is considered one of the best air purification technologies available. It has germicidal properties that can kill bacteria, viruses, mold, and other particles that can cause illness. This makes it an excellent way to improve indoor air quality and make everyone in your household breathe easier. However, it's important to understand that UV lights are not a foolproof solution for preventing the spread of COVID-19. While they can help reduce the risk of infection, they are not a replacement for other safety measures such as wearing masks and social distancing. There are two main types of UV lights used in HVAC systems: coil lights and disinfectant lamps.
Coil lights are installed inside the air conditioner to prevent the growth of bacteria and mold in the evaporator coil. Disinfectant lamps, on the other hand, are installed to work constantly and are placed to attack areas most sensitive to microbial growth. When it comes to installation, it's important to note that placing UV lights in the system's ducts will require more work and is not recommended. Most UV HVAC lamps are designed to draw power from the fan, so they only work while the air controller is turned on. This means that they are not constantly disinfecting the air, but rather only when the HVAC system is running. Now, let's talk about cost.
The good news is that UV HVAC lights are relatively affordable, especially compared to other air filtration systems such as purifiers and filters. The exact cost will depend on factors such as the type of UV light, the size of your HVAC system, and whether you hire a professional for installation. While UV lights may seem like a significant investment upfront, they can have long-term benefits for your home and family. By improving indoor air quality and reducing the risk of illness, they can save you money on medical expenses and improve overall well-being. In conclusion, UV lights can be a valuable addition to your residential HVAC system. They have proven benefits for improving indoor air quality and reducing the spread of illness.
However, it's essential to take proper safety precautions and understand that they are not a replacement for other safety measures. With careful consideration and professional installation, UV lights can be a worthwhile investment for your home.
