As an HVAC expert with over a decade of experience, I have witnessed numerous trends come and go in the industry. One trend that has gained significant popularity in recent years is the installation of UV lights in HVAC systems. These lights are believed to enhance indoor air quality and eliminate harmful germs and bacteria, making them especially appealing during the ongoing COVID-19 pandemic. However, as with any new technology, there are important factors to consider before investing in UV lights for your HVAC system. First and foremost, it is crucial to understand that UV lights only work when the device is turned on.
This means that you will need to run the lights for a few hours after installation to see any real benefits. While this may seem like a minor inconvenience, it is something to keep in mind when considering the cost of installation. Speaking of cost, let's address the elephant in the room: how much does it actually cost to install UV lights in an HVAC system? The answer is not a simple one. While it is true that you can add powerful UV lights to your air conditioning system, this is likely an overstatement and can cost you thousands of dollars. In fact, most HVAC companies will try to sell you on expensive UV light units that may not be worth the investment. So, what's the alternative? Many experts, including myself, believe that it is more cost-effective to manually clean your HVAC system once a year rather than investing in expensive UV lights.
Not only is this a more affordable option, but it also ensures that your system is properly maintained and functioning at its best. However, if you do decide to go ahead with installing UV lights in your HVAC system, there are two types to choose from: coil sterilizing lights and air purifying lights. Coil sterilizing lights are pointed directly at the air controller's coil to sterilize any bacteria or mold that may be present. On the other hand, air purifying lights work to eliminate harmful particles from moving air, making it easier to breathe and improving the overall efficiency of your HVAC system. One important thing to keep in mind is that UV bulbs can become less effective when covered in dust. This means that you will need to clean them regularly, about once every two months, to ensure they are working properly.
If you live in a particularly dusty area, you may need to clean them even more frequently. Ultimately, the decision to install UV lights in your HVAC system comes down to your specific needs and budget. If you suffer from allergies or respiratory problems, or if you have mold issues caused by excess moisture, then investing in UV lights may be worth the extra expense. However, if these are not concerns for you, it may be more cost-effective to stick with manual maintenance.
