The Pros and Cons of Installing UV Lights in Your HVAC System

As an HVAC expert, I have been frequently asked about the advantages of incorporating UV lights into air conditioning systems. The reality is that airborne viruses, mold spores, and bacteria are ubiquitous, but they thrive in sensitive areas deep within the system that tend to get damp. By installing UV lights in your HVAC system, you can help prevent contaminants from circulating throughout the house and improve air quality. UV lights are an enhancement to the HVAC system that aids in combating allergies and enhancing air quality. They work by emitting a higher frequency UV light that has enough energy to destroy the DNA of bacteria and other microorganisms, effectively killing them and disinfecting the air.

These lights are typically installed inside the boiler, air conditioner, heat pump, or duct to eliminate bacteria, mold, allergens, and other germs before they enter your home (and your lungs).One of the main benefits of UV HVAC lights is their ability to disinfect air as it circulates through the ducts. This eliminates harmful bacteria, mold, and other airborne contaminants that can cause respiratory problems. Researchers have found that viruses can travel through particles of water suspended in the air, so having UV lights installed in the ducts that treat the circulating air can be especially useful. However, it's important to note that there are also some drawbacks to consider before investing in UV lights for your HVAC system. While they may seem like a great solution for improving air quality, there are a few things to keep in mind. Firstly, it's crucial to have a certified HVAC technician install these accessories to ensure the integrity of your system and achieve optimal results.

Additionally, maintenance is required every three months - you will need to turn off the climate system, remove the lamp, and clean the UV bulb with a soft cloth. This can be a bit of a hassle, but it's necessary to keep the lights working effectively. Another drawback to consider is that UV lights may not be as effective as you may think. While they can be quite effective in preventing mold and bacteria from growing on the condenser coil and drain pan, they may not have as much of an impact on the circulating air. This is because the UVC radiation doesn't interact with the air for an extended period. When it comes to cost, installing UV lights in an HVAC system can vary depending on the type of lights you choose and whether or not you hire a professional to install them.

However, for those who live in humid and damp climates, investing in a UV HVAC air purifier could be a proactive step towards improving air quality and preventing respiratory problems.
