UV Light Systems in Florida

If you have heard about ultraviolet or UV light systems, you may be interested in having such a device installed in your HVAC system. Learn more about UV lights to see if they’re right for your home.

What Are UV Light Systems?

UV lights are specially designed for use in HVAC systems. These devices provide superior indoor air cleaning by emitting germicidal energy that inactivates mold, viruses, and bacteria.

UV light systems were first introduced in the mid-90s. Still, these devices are in their infancy compared to conventional media air filters, which have been a standard in forced-air heating and cooling systems since they were first introduced.

These devices are meant to be used alongside media air filters, which are designed to trap dirt, dust, and other non-living debris. Together, UV lights and media air filters produce much cleaner indoor air.

Benefits of UV Light Systems

If media air filters are considered the conventional method of filtering out airborne contaminants, are UV lights really necessary? Consider the benefits of this additional air cleaning method and decide for yourself.

    • Cleaner air: Media air filters come in a variety of efficiencies. Some are woven tightly enough that they can trap bacteria and viruses. However, most residential HVAC air filters are not this efficient because they restrict airflow and cause additional strain on the heating and cooling equipment. UV lights, on the other hand, kill microorganisms that cause health problems in those with respiratory sensitivity without blocking airflow. In this way, UV light systems provide much-needed relief from wheezing, coughing, sneezing, chest tightness, and nasal congestion.
    • Energy savings: An efficient HVAC system relies on many things, including clean equipment and ductwork walls. Since UV lights help improve the cleanliness of everything within the HVAC system, including the all-important evaporator coil, it runs more efficiently. In this way, UV lights help your equipment perform like new for many years to come with regained system capacity that decreases energy bills by 10 to 35 percent.
    • Lower maintenance requirements: HVAC systems generally require a thorough once over every year. A technician cleans every component and makes sure everything is working properly. While you should continue to schedule annual preventative maintenance, UV lights help everything stay cleaner so your system is less prone to breakdowns.
    • Improved airflow: Dirty coils and a clogged air filter reduce the volume of air traveling through the ductwork. UV lights slow the dirtying process so airflow remains ideal from one professional maintenance visit to the next. Proper airflow is essential to properly remove humidity and keep your home at the desired temperature.

UV Light Installation

If you’re serious about installing UV lights in your Florida home, make sure you go about the installation in the right way. Work with a contractor that understands the importance of:
Choosing UV lights with the right output: High-output lamps are specifically designed for use in HVAC systems. The germicidal light output is critical for you to enjoy the benefits of inactivated microbial contaminants.

    • Properly sizing UV lights: A technician determines the minimum number of UV lights needed to maximize air cleaning, energy savings and system performance benefits.
    • Properly installing UV lights: The lights are typically installed about 12 inches from the downstream side of the evaporator coil, though field experience has verified that anywhere between 3 and 30 inches works fine.
    • Remembering change-out cycles: UV lights lose output over time, reaching their half-life after about one year, which is when change-out is recommended to maintain microbial control.
