As an expert in the HVAC industry, I have seen many companies trying to sell UV lights as a solution for improving indoor air quality. But the question is, how much does it really cost to install these lights in your HVAC system? Let's dive into the facts and debunk some common misconceptions. First of all, there are two types of UV lights commonly used in HVAC systems: coil sterilization and air sterilization. Coil sterilization is the more affordable option and is just as effective as air sterilization. These lights require minimal maintenance and only need to be cleaned or replaced when necessary. Once installed, germicidal UV lights can kill harmful pathogens such as mold spores, bacteria, and viruses.
This can greatly improve the overall air quality in your home. However, many companies will try to sell you expensive UV lights that may not be necessary. In fact, regular maintenance of your HVAC system can achieve similar results. If you do decide to install UV lights, it's important to consider the size of your system. Larger systems have more space for installation, making it easier to place the UV luminaires.
Not only do these lights benefit your health, but they can also improve the efficiency of your HVAC system. Most UV HVAC lamps are designed to draw power from the fan, so they only work when the air controller is turned on. If this is not possible, you can connect the light to a nearby electrical outlet using an appropriate extension cord. It's important to note that UV lights should never be looked at directly. Even brief exposure to UV light can cause permanent eye damage. Unlike coil sterilizing lights that target the coil of the air controller, this type of UV light removes harmful compounds from the moving air. Despite the benefits of UV lights, they are often one of the most affordable options for improving indoor air quality.
This can also help reduce future repair needs and potentially extend the life of your HVAC system. However, it's important to be aware that some HVAC companies may push UV filtration as a new and innovative technology. The truth is, it may not be as effective as they claim. Adding super-powerful UV lights to your system can cost thousands of dollars and may not provide the desired results. Additionally, mounting UV lights to the ducts of your system can be a more complicated and costly process. It's not recommended unless absolutely necessary.
