Why It Matters

Most indoor air pollution survives traditional filtration.

HEPA filtration captures particles — but living pathogens like bacteria, viruses, and mold spores can pass through and multiply on the moist surfaces inside your HVAC system. UV-C destroys their DNA at the source, stopping reproduction before air re-enters your home.

Critical for homes with allergies or asthma, after mold remediation, for immunocompromised residents, post-wildfire smoke recovery, and families with infants or elderly.

  • Kills 99.9% of bacteria & viruses — including coronaviruses and influenza.
  • Eliminates mold growth at the coil — stops the #1 source of musty AC smell.
  • Removes odor-causing biological matter — cleaner-smelling air within two weeks.
  • Improves HVAC efficiency — a clean coil transfers heat better, cutting run time.

Frequently Asked

About UV-C installation.

Specific questions about UV-C light installation. For general questions, see the main FAQ.

Is UV-C safe for my family and pets?

Yes. The light is fully enclosed inside the HVAC cabinet — never exposed to living areas. It only operates when the blower runs, sterilizing air as it passes the coil.

How often does the bulb need replacement?

Every 18-24 months (9,000 hours of operation). We send you a reminder when it's time. The bulb itself costs around $50 and takes us about 15 minutes to swap.

Does it work on COVID-19 and other viruses?

Yes. UV-C at 254nm is proven to inactivate enveloped viruses including coronaviruses and influenza. It's the industry standard for hospital sterilization.

Will I notice the difference?

Most homeowners notice cleaner-smelling air within two weeks, fewer allergy symptoms, and no musty smell when the AC kicks on after a vacation. Big difference for asthma and sinus sufferers.

Can I bundle UV install with air duct cleaning?

Highly recommended — install the UV directly after a deep clean for the best long-term result. Same visit, significant savings. We do this combination on most projects.
