What to expect from LC Heating & Air
### UV-C Lights in HVAC Systems Ultraviolet-C (UV-C) germicidal light systems installed inside HVAC equipment use the same technology that hospitals and water treatment plants rely on to neutralize biological contaminants. When installed in an HVAC system, UV-C lights continuously irradiate the evaporator coil and surrounding air handler surfaces — the areas most prone to mold and biofilm growth in the warm, wet environment of a cooling system. LC Heating & Air installs germicidal UV-C systems throughout Greater Los Angeles.
Overview
### Two Types of HVAC UV Systems Coil-sterilization UV systems install a UV-C lamp directly in front of the evaporator coil. The lamp runs continuously (or whenever the air handler runs) and prevents mold and biofilm from establishing on the coil surface. This is the most common and effective UV application in residential HVAC — keeping the coil clean dramatically reduces the musty smell that many LA homeowners notice when their AC runs, particularly in humid coastal areas. Air-sterilization UV systems install in the return duct and use stronger lamps to neutralize pathogens in moving air — more effective for airborne biological concerns but requiring higher-intensity lamps for adequate exposure time.
### Why Mold on Evaporator Coils Is a Real Problem in LA The evaporator coil is a perfect environment for biological growth: it alternates between cool and damp (when the AC runs) and warm and humid (when the AC is off). This wet-dry cycle, combined with the organic matter captured on the coil surface, supports mold and bacteria growth that is then distributed through the supply ductwork into the living space. A UV coil sterilization system disrupts this cycle — keeping the coil surface biologically clean without chemicals.
### Installation Details Coil UV installation requires accessing the air handler, cutting a small access port if one doesn't exist, and installing the UV lamp assembly and power supply. Installation typically takes 60–90 minutes. We recommend replacing UV bulbs annually — they lose germicidal effectiveness before they burn out visually.

What customers say about uv light installation
Verified reviews from Los Angeles homeowners who used our uv light installation service.
“Post-fire air quality in our Altadena home was terrible. LC installed a whole-house HEPA filtration system and UV germicidal light in the air handler. Our allergist confirmed improved air quality on our next visit.”
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
