UV lights are an affordable, effective, and low-maintenance solution for homeowners with air conditioning systems. Even if your air conditioner has a high-quality filter, adding a UV light can help eliminate microorganisms and bacteria that may be too small to pass through the filter. Studies have shown that spiral disinfectant lights can significantly reduce the amount of live fungi in an office air conditioning system. Not only do UV lights help reduce allergies and energy costs, but they also prevent common air conditioner damage.
When bacteria accumulate in the evaporator coil, it prevents adequate air flow and can cause the air conditioner to freeze. By preventing bacteria from growing in the evaporator coil, the air conditioner will work more efficiently and avoid costly repairs. A complete UV light unit can be connected directly to the air ducts to disinfect the air entering the machine. This helps keep the coils and drain pan clean, reducing both wear and maintenance requirements.
UV lights are capable of eliminating 97% of bacteria, even those resistant to antibiotics, as well as viruses and mold. Most homeowners in Atlanta combine germicidal UV lights with an air filter that has a high MERV rating (minimum efficiency values). In addition to installing a UV lamp, it's important to change the air filter regularly, inspect and clean the ducts, and make other positive changes to improve air quality. UV lights are worth it if you or your family suffer from allergies or illnesses caused by germs or particles that no other tool can remedy.
However, UV bulbs work less effectively when they're covered in dust, so you'll have to clean them quite often - about once every two months - to make sure this doesn't happen.
