When you’re tasked with keeping a building operating at optimal efficiency, every little detail matters. Your HVAC system is integral in accomplishing this goal, as it is responsible for maintaining safe working temperatures for employees and equipment.

Your HVAC system should not only regulate the temperature, it should keep the air clean and free from bacteria as well. This has become all the more important in light of the coronavirus pandemic.

Unfortunately, commercial HVAC systems incorporate massive ventilation ducts, which can be a breeding ground for bacteria and viruses. This can cause widespread contamination that could infect an entire staff, compromising their well-being and bringing productivity to a grinding halt.

A proven way to prevent this is through the use of ultraviolet HVAC systems. These devices eradicate airborne contaminants, leaving your facility with crisp, clean air.

What Is UV for HVAC?

Ultraviolet HVAC systems are devices that are installed within your existing heating and cooling units. There are several different types of commercial HVAC UV lighting systems, which are explained below.

These devices emit “C” waves of ultraviolet light, which have been used in hospital settings for many years. These lightwaves have a proven track record of destroying airborne contaminants and curbing the spread of disease. In fact, the Center for Disease Control has confirmed that ultraviolet germicidal irradiation is one of the “most promising” methods of decontamination when it comes to fighting COVID-19.

Ultraviolet HVAC Systems

When it comes to commercial HVAC UV lighting solutions for your facility, you will have two main options. The first is known as coil sanitizing lights. These lights are installed near your system’s coils and shine directly onto them.

The coils are an ideal location for the formation of bacteria and mold. This is because the air passes over them during the cooling cycle. The air carries a wide variety of contaminants, many of which become stuck to the coils.

Coil lights are the most common of the two ultraviolet HVAC systems. They are typically available in either single-lamp and dual-lamp models.

An alternative type of UV lighting system is air sanitizing lights. Instead of being installed near your coil, this system is placed within the ductwork near the return air vent. These lights are designed to kill airborne contaminants as the air is drawn back into your HVAC system.

Depending on the manufacturer, air sanitizing lights may be U-shaped or stick-shaped. They can even be hardwired into the thermostat so that they turn on and off with the rest of the HVAC system.

Benefits of Commercial UV Systems

As mentioned above, the most apparent benefit of ultraviolet HVAC systems is that they help to combat airborne bacteria. This can reduce the frequency of employee illness, and curb the spread of illness.

A reduction in sick day use can boost employee morale and increase productivity. This can have long-term benefits for your company’s financial outlook. Over time, the UV lighting system will pay for itself.

A quality ultraviolet HVAC system can also save you money in other ways. Since the lights will reduce the build-up of mold and debris within your ductwork, your HVAC system’s key components will stay cleaner and function more efficiently. This can reduce the frequency of major repairs and maintenance calls, which will eliminate thousands of dollars in expenses.
