Can You Use UV Lights in Your HVAC System?

Can You Use UV Lights in Your HVAC System?

Air molecules carrying bacteria, mold spores, and other harmful microorganisms can pass through your HVAC system and circulate through your home or office building. While air filters can help stop larger molecules, microorganisms can slip through. To effectively sterilize nearly all of the germs that pass through your system, you should consider installing UV HVAC lights.

Before doing that, you probably have some questions about UV lights and how they work. Read on to find out if this would be something you want in your home.

How Do UV Lights Work?

UV air purifiers capture air using UV light technology and pass it through a filter. There, the air goes into a small chamber and is exposed to UV-C light. During this process, potentially harmful microorganisms and germs are sterilized, and purified air is released. 

How Are They Attached to Your HVAC System? 

So where would you install UV lights in your HVAC system? This is where it helps to have the help of a professional technician (like ours). HVAC technicians can help you decide the most effective place to put the UV lights. Typically, you’ll install them on the indoor coil (coil UV lights) or in the ductwork. 

Coil UV lights can help control mold from condensation that typically collects on the coil. The lights can be installed above the coil, allowing it to continuously shine in troubled areas. 

Ductwork UV lights can eliminate airborne allergens, pollutants, and more, as they move through return vents. The UV lights activate when your HVAC’s blower motor does, which will turn on and off when appropriate. 

How Long Do UV Lights for HVAC Last? 

A UV lamp used to disinfect the air in your home or office should be replaced every 9,000 hours or annually. However, replacing it before then isn’t wasteful or a bad idea. After about a year of use, the UV light loses half of its effectiveness. By replacing it at least once a year, you’re practically guaranteeing its air sterilization effectiveness.
