What are UV Lamps Used for in A/C Systems?
By Travis Baugh
An ultraviolet (UV) lamp can be added to your existing HVAC system and is installed in the evaporator coil or ductwork near the coil. Unlike air purifiers, which just filter out contaminants, ultraviolet lights for ac systems help clean the coil by killing bacteria, mold, and mildew so they do not become airborne and circulate throughout your home.
How DOES AN AIR CONDITIONING SYSTEM W/ UV LIGHT WORK?
UV light is a form of radiation—it’s also present in sunlight. In concentrated forms, it efficiently kills bacteria, mold, and mildew. A UV lamp made for your air conditioner looks like a fluorescent light tube. When installed inside the condenser, the light shines directly on the coil and helps prevent the buildup of harmful contaminants.
WHAT ARE UV LAMPS GOOD FOR?
UV lamps in AC systems can improve air quality by killing bacteria, viruses, and mold spores, reducing allergens, and preventing mold and mildew growth on the coils. This helps maintain system efficiency, extends the equipment's lifespan, and reduces maintenance costs. Additionally, UV lamps can eliminate odors caused by biological contaminants, resulting in fresher indoor air.
Is it safe to have a UV lamp?
Yes, it is generally safe to have UV lights in your hvac, provided it is used correctly and installed by a professional. Here are some important considerations to ensure safety:
- Correct Placement: UV lamps should be installed in a location where they can effectively target the coils and air handler surfaces without exposing inhabitants to direct UV light.
- Proper Shielding: Ensure that the UV lamp is properly shielded to prevent UV light from escaping into living spaces, as direct exposure to UV-C light can be harmful to skin and eyes.
- Replace Bulbs as Needed: UV bulbs lose their effectiveness over time and should be replaced by a trained technician according to the manufacturer's recommendations, typically every 12 to 24 months.
- Clean and Inspect: Regular maintenance of the UV lamp and HVAC system by a trained technician helps ensure optimal performance and safety.
- Professional Installation: Professional installation of UV lights for hvac systems by your local Carrier dealer is crucial for ensuring both safety and effectiveness.
What are the Benefits of ULTRAVIOLET LIGHTS FOR AC SYSTEMS?
Installing a UV lamp in your air conditioner system’s evaporator coil kills contaminants that can grow in moist environments, like bacteria, mold, and mildew. Eliminating these can result in:
- Increased energy efficiency for your HVAC system
- Improved indoor air quality
- Reduced allergens circulating within your home.
- Reduce unwanted odors.
- Helping to extend your equipment lifespan
