How does a UV light work on cleaning the air

Back in the 1990’s was the first time that specially designed Ultraviolet lights were installed into HVAC systems. These lights were engineers to provide a high level of output while working under the harsh conditions of HVAC operations. These UV lights are high-output devices that will emit ultraviolet energy that will destroy microbial contaminants such as surface and airborne mold, bacteria and even viruses.

As the popularity of these UV units grew people started discovering even more benefits to having ultraviolet lights installed in the heating and air conditioning systems. They found that their units were cleaner than before and did not require as much maintenance as was needed in the past. This also resulted in the units being more energy efficient and having a longer lifespan.

Now wise homeowners see that there is a rapid return on investment of installing a quality ultraviolet light in their HVAC system. This has rapidly progressed from a virtually unknown technology to now being widely adopted in school systems, large companies, offices, hospitals, warehouses, public buildings as well as homeowners across the United States and the world. In fact, many federal buildings are now required to have UV lights installed in their systems.

When selecting an UV device to install into your system it is very important to hire a qualified contractor to perform this task. They will know exactly where to install it to get the most benefit. These devices can now be installed successfully in a number of locations including the ductwork and air returns. Usually the most effective location is to mount it near the downstream side of the cooling coil where it can provide the most benefit.

Why would it be so important for you to treat the coil? Because there are these complex microorganisms that can grow in the coil and drain pan called “biofilms.” These can be very hard to eliminate and treat with conventional methods but are easily overcome with UV light. If the biofilm is allowed to build up it can create a whole host of problems and lead to a variety of operational problems.

To keep the coils clean the ultraviolet light should be installed about twelve inches away from the coil and fins. If the UV light is higher powered then you may choose to locate it further away. A skilled technician will be able to give you the proper guidance and will be able to install it most effectively.
