Kill 99.9% of Mold & Bacteria in Your Ducts
UV-C germicidal lights installed inside your HVAC system destroy mold, bacteria, and viruses at the source — before they circulate through your home. The same technology used in hospitals, now available for your family.
What UV-C Germicidal Lights Eliminate
UV-C at 254nm is the most rigorously studied germicidal technology available. Here is what peer-reviewed research shows it destroys in your HVAC system.
Black Mold (Stachybotrys)
Destroys mold spores on evaporator coils and in ductwork — the leading source of indoor mold contamination.
Bacteria (E. coli, MRSA)
UV-C ruptures bacterial cell walls, eliminating pathogens that cause respiratory infections and illness.
Viruses (Influenza, COVID)
Inactivates airborne viruses in a single pass. ASHRAE-recommended for IAQ improvement in healthcare settings.
Volatile Organic Compounds
Photocatalytic UV models break down VOCs from paints, cleaning products, and off-gassing furniture.
Dust Mite Allergens
UV-C destroys the protein structure of dust mite fecal allergens — a primary trigger for asthma attacks.
Biofilm on Coils
Continuous UV exposure prevents the slimy biofilm that reduces HVAC efficiency by up to 25% on untreated coils.
Two Types of UV-C Systems — We Install Both
The right system depends on your goals. Most homeowners benefit from both working together.
Coil-Mounted UV Light
Mounted inside the air handler to shine continuously on the evaporator coil. Prevents the mold, biofilm, and microbial growth that makes your coil a breeding ground. Also improves HVAC efficiency by keeping the coil clean.
- Prevents coil mold & biofilm
- Improves HVAC efficiency 5–15%
- Installation: 45–60 min
- Cost: $300–$500 installed
In-Duct UV Air Purifier
Installed inside the main supply duct, this high-output system treats every cubic foot of air passing through your HVAC. Ideal for allergy sufferers, asthma patients, or homes with active mold history.
- Treats all circulating air
- Kills viruses & bacteria in-flight
- Installation: 60–90 min
- Cost: $450–$800 installed
Pro Tip: Pairing both systems provides whole-home coverage — coil-mounted prevents source mold growth while in-duct UV treats circulating air. Combined cost is $650–$1,200 installed. We offer a bundle discount when you add UV to any duct cleaning service.

UV Light + Duct Cleaning: The Ultimate IAQ Solution
Duct cleaning removes the accumulated debris, allergens, and contaminants from your duct surfaces. UV light installation then creates a permanent, self-operating defense against future microbial growth. Together, they address both the existing problem and prevent recurrence.
Duct Cleaning First
We clean and vacuum all duct surfaces, removing mold, dust, and debris that could absorb UV energy and reduce effectiveness.
UV Installation
With clean surfaces, UV-C light penetrates fully and begins continuously preventing new microbial growth 24/7.
Long-Term Protection
Your HVAC system becomes self-maintaining — the UV light handles microbial control between your regular duct cleanings.
