Fighting COVID-19 with UV Light: HVAC Service in Port St. Lucie

UV light wands used for disinfecting ductwork.

As the entire world is battling the Coronavirus pandemic, many Americans worry about it spreading in their homes. One of the highly effective weapons against the dangerous virus is UV light. Since the ductwork cleaning season is approaching, it's time to take advantage of the new HVAC service in Port St. Lucie.

 

Can UV Light Kill Coronavirus?

Three key types of UV rays exist. They are UVA, UVB, and UVC. The latter has the shortest wavelength and the highest energy. It's capable of killing viruses, including the new COVID-19. With the wavelength of between 200 and 400, the light can destroy molecular bonds that hold together the virus' DNA.

Hospitals, medical laboratories, and restaurants have been using UVC light for decades to decontaminate surgical tools, surfaces, and air. A study (1) published in the International Journal of Environmental Research and Public Health showed that a pulsed UVC light treatment is highly effective for disinfection. 

The downside of using this light to fight viruses is that it may be harmful to people, but only through direct contact. UVC light has been linked with skin cancer and skin irritation. (2) Even though more research is needed, to be on the safe side, this light shouldn't be used when people are around. Hospital rooms and restaurants are generally disinfected while empty.

What Are UV Light Systems for HVAC?

UV Light systems for ductwork sanitize the surfaces and air inside your HVAC system, making sure bacteria, viruses, and fungi don't circulate through your home.

Two types of UV light systems for ductwork exist:

  • Coil Sterilization – a stick-type light is placed inside the return air duct to sterilize the handler coil. This light is on 24/7 for continuous sterilization.
  • Air Sterilization – a UV light unit is installed in the return air duct to sterilize the air moving through the ductwork. It can be coordinated with the blower motor.

While the DIY installation of both systems is possible, professional assistance comes recommended to ensure proper operation.

Can You Use UV Lights at Home?

If you hire professional HVAC repair services, you have an opportunity to take advantage of UV light devices that kill viruses and bacteria in the ductwork.

An HVAC maintenance expert can use the UV light system to clean your ductwork during routine preventive maintenance or install a system for continuous disinfection.  

When you take advantage of UV light purification systems for ductwork, you can be sure that viruses aren't spreading through the house. They are eliminated inside the ducts (3). Meanwhile, you avoid any health hazards posed by the UV light since you never come into contact with it.

When you hire an AC repair in Stuart, consider asking about your options to install such a device in your HVAC system. Since COVID-19 can stay alive on the surface for two to three days, regular disinfection can be a smart choice.
