You may have heard about UV lights for air conditioning systems. They are small lamps installed inside your system, and they work quietly in the background. Here is a simple guide to what they do.
How a UV light works
A UV-C lamp is usually installed inside the air handler, near the evaporator coil. When your AC runs, this coil stays cold and damp, which can make it a place where mold and bacteria grow. UV-C light shines on the coil and nearby surfaces and helps limit that growth over time.
What a UV light does not do
- It does not replace your air filter.
- It does not remove dust from your ducts.
- It does not replace regular cleaning of your system.
Think of it as one extra step that helps keep a clean coil cleaner for longer.
Who may benefit
- Homes that have had mold on the coil or in the drain pan
- Systems where the coil gets dirty or slimy quickly
- Homeowners who notice musty smells when the AC runs
- Anyone who wants an added step after a deep system cleaning
Care and safety
Most UV-C bulbs are replaced about once a year, depending on the model. The lamp sits inside the closed air handler, away from people. Never look directly at a UV-C lamp, and always turn the system off before opening the unit.
For best results, pair a new UV light with coil cleaning so the light starts working on a clean surface.
