Do HVAC UV Lights Really Kill Germs in Your Home?

HVAC UV Lights

It may sound too good to be true, but just shining UV lights into your air ducts really can improve your home’s air quality.

Ultraviolet (UV) lights for HVAC systems are commonly known as ultraviolet germicidal irradiation (UVGI) systems. UVGI systems produce the same ultraviolet light that’s present in the sunshine. This light destroys germs or molds clinging to the inside of your ductwork or on your coils.

Coil Sterilization

This is the most common type of light system that’s installed near the air conditioner’s indoor evaporator coil and shines constantly to prevent mold and bacteria from building up on or around the coil.

Air Sterilization

This system is designed to kill microbes in your air. It’s installed in the return air duct and turns on only when the heating or cooling system is running. It purifies all the air passing through it which reduces the risk of microbial buildup on your components. In humid climates, your evaporator coil is at a greater-than-average risk of getting wet and developing mold. A UVGI system reduces the number of active mold spores on the coil and in the air.

Who needs UVGI

If someone in your household has:

  • Asthma
  • Allergies
  • Chronic obstructive pulmonary disease (COPD)
  • Weakened immune system

Any additional air purification can pay off.

Additional benefits:

  • Increased airflow
  • Improved HVAC efficiency
  • A decrease in energy costs
  • Improved air quality
  • Reduces clogging in the condensation drain line
