What Is a UV Light and How Does It Help Your AC System?

You may have heard about UV lights being added to air conditioning systems—but what do they actually do, and are they worth it?

A UV light (ultraviolet light) is installed inside your HVAC system, typically near the evaporator coil or air handler. Its job is to help keep the inside of your system clean and operating efficiently.

How a UV Light Helps Your System:

- Reduces mold and bacteria

Moist, dark areas inside your AC system are the perfect place for mold and bacteria to grow. UV light disrupts these microorganisms, helping prevent buildup on coils and internal components.

- Improves system efficiency

When mold and debris build up on the evaporator coil, airflow is restricted and your system has to work harder. A cleaner coil allows air to flow freely, helping your system run more efficiently.

- Helps improve indoor air quality

By reducing microbial growth inside the system, fewer contaminants are circulated through your home, which can mean cleaner, fresher-smelling air.

- Extends equipment life

Less buildup means less strain on your system. That can help reduce breakdowns and extend the life of major components.

Is a UV Light Right for You?

UV lights are especially helpful in humid climates, homes with allergy concerns, or systems that struggle with mold growth. They work quietly in the background and require minimal maintenance, usually just a bulb replacement once a year.
