The dark, moist and unhealthy environment in clogged air ducts makes the perfect conditions for bacteria to grow. We fix that through powerful UV lights, killing microorganisms at the source.


One of the most effective ways to achieve a cleaner home or office is addressing the dirt buildup in air ducts. While standard air duct cleaning helps remove dust and allergens, it doesn’t remove the bacterial microorganisms deeply embedded in the ductwork. To remove them, you need something stronger. At Delta Air Duct DMV, we achieve that through UV installation.
Killing bacteria has never been this easier. Installing a UV light in HVAC systems destroys the root cause of bacterial growth. Whether you’re a homeowner or a business owner, the impact of UV light installation is impeccable. You not just get a cleaner environment in your space, but also get to enjoy a sense of freshness and improved air quality that reduces your energy consumption.

Skeptical of UV lights? You may be wondering if they’re legit or just another gimmick in the market. UV-C lights date back to the 1800s, designed to treat diseases in medical facilities. Gradually, they were adapted for use in air ducts to kill harmful microorganisms and achieve a cleaner home. The science behind their functionality is simple. A UV-C light uses a certain wavelength of ultraviolet light to inhibit the DNA or RNA of microorganisms, killing them in the process. In air ducts, you mainly see two types of UV light systems:

UV lights are powerful systems that destroy viruses and bacteria, but they don’t last forever. Different UV light systems have different lifespans depending on the manufacturer. You can expect a typical UV light system to last for 9000 to 12000 hours, equivalent to 12 months. Your UV bulbs wouldn’t necessarily break down after this period, but they’ll lose their overall effectiveness. This is why annual replacements of UV lights are important to keep your HVAC system virus-free, especially if you’re prone to allergic reactions or sicknesses.

System Inspection
We inspect your air ducts first and identify the best placement for the UV lights, whether it’s near the evaporator coil or within the return duct.

UV Bulb Selection
Our goal is to deactivate microorganisms in your air ducts. We do this by choosing a UV bulb that aligns with your air purification goals and fits your ductwork.

Preparing Installation
To prepare the installation process, we shut off the power supply to the HVAC system first. We drill a hole in the air duct to create room for the UV bulb installation.

Mounting the UV Bulb
We proceed with mounting the UV light unit inside the ducts. We align it properly so that evaporator coils, return ducts, and drain pans are exposed to ultraviolet light.

Electrical Wiring
After installing the UV light, we wire it into the HVAC system. This turns on the UV light whenever your HVAC system is running, killing viruses at the source.

System Check
To maintain safety and compliance, we test your whole HVAC system to check if the UV lights are running properly. We also provide pointers to maintain your system.
