HVAC UV Light Installation
Ultraviolet germicidal lights are one of the most effective ways to eliminate biological contaminants inside your HVAC system. Installed in the air handler or ductwork, UV-C lights destroy bacteria, viruses, mold spores, and other microorganisms as air passes through — preventing them from circulating through your home and growing on your evaporator coil.
All Seasons Heating & Cooling installs HVAC UV light systems across the Fox Valley and DuPage County, including the Fox Valley, Wheaton, Batavia, Geneva, St. Charles, North Aurora, and South Elgin. We help you choose the right UV system for your air quality goals and install it for maximum effectiveness.

What Our Customers Are Saying
How HVAC UV Lights Work
UV-C light (shortwave ultraviolet at 254 nanometers) has been used in hospitals and water treatment facilities for decades to kill pathogens. When applied to your HVAC system, it provides continuous disinfection in two key ways:
Coil-sterilization lights: Mounted near the evaporator coil inside the air handler, these lights run 24/7 to prevent mold and biofilm growth on the coil surface. The evaporator coil is dark, damp, and cool — the perfect environment for mold. A UV light keeps it clean without chemicals, maintaining airflow and system efficiency.
Air-sterilization lights: Mounted in the return duct or supply plenum, these lights treat the air as it passes through. They’re most effective against airborne bacteria, viruses, and mold spores. Higher-intensity models with longer exposure times provide better kill rates.
Many homeowners install both types for comprehensive protection — coil lights to keep the equipment clean and air lights to treat what’s circulating through the home.
Benefits of UV Light in Your HVAC System
Adding UV light to your HVAC system provides several measurable benefits:
- Kills mold on the evaporator coil: Mold on the coil restricts airflow and reduces cooling efficiency. UV light eliminates it without chemical cleaning
- Reduces airborne pathogens: UV-C light destroys bacteria, viruses, and mold spores as air circulates through the system
- Eliminates musty HVAC odors: That “dirty sock” smell from your vents is usually mold on the coil. UV light eliminates the source
- Improves system efficiency: A clean coil transfers heat more effectively, reducing energy consumption
- Low maintenance: UV bulbs typically need replacement once a year — that’s it. No filters to change, no moving parts
- Works with your existing system: UV lights install inside your current air handler or ductwork with no modifications to the HVAC equipment itself
