UV Light Installation
Indoor Air Quality Priorities
While HVAC UV lights are effective for killing mold, bacteria, germs and odors, make sure you have completed the indoor air quality basics:
- Seal air ducts during renovation or construction
- Install ducts in conditioned space
- Ensure air-tight ducts, sealing all joints with mastic. See this Duct Sealing Guide from Building Science Corporation.
- Install high-MERV filters, but be sure your HVAC system is designed for the higher static pressure of better filtration
- Install UV light in HVAC system
- Conduct regular maintenance, changing filters monthly and cleaning the coil annually
HVAC UV lights:
- Control mold and bacteria
- Reduce colds and flus – germs are not re-circulated by HVAC system
- Reduce smells / odors
- Remove VOCs
- Are more effective in humid climates than dry climates
- Reduces clogging in condensate drain lines by preventing algae growth.
- Maintain a cleaner coil, improving cooling efficiency and reducing electricity costs.
HVAC UV Lights:
- Don’t clean flowing air unless air sterilization UV lights are installed
- Destroy non-UV stabilized plastics in the air handler. Only items in the line of sight are affected
- May eat the drain pan in 3-5 years
- May eat flex duct in as little as 2 years
- Sanuvox (air sterilization, coil sterilization)
- TopTech Air Knight (coil sterilization)
- Guardian Air / REME (coil sterilization)
- Fresh-Aire (Triatomic Environmental) (coil sterilization)
- Honeywell – (coil sterilization) Be sure to pick the new model lamps
- Lennox Healthy Climate UVC Germicidal Lights (coil sterilization)
- Carrier Performance Series Germicidal UV Lamps (coil sterilization)
- Trane – Perhaps their opinion has changed since posting Trane’s Position on UV-C Lights
HVAC UV lights are an effective means for improving indoor air quality, but only after following the indoor air quality priorities. Install an HVAC UV light and experience healthier indoor air quality.
