Can UV Light Protect Us from Bacteria in Ducts?mmihomeimprovement.com/2021/03/26/can-uv-light-protect-us-from-bacteria-in-ducts
We know that mould and bacteria are very harmful particles, and when it enters the
HVAC system, the damage is uncontrollable. HVAC owners must know that contaminants
multiply and infect the air quality. This can have serious impacts on the health and
wellbeing of people. So, what is the way out? In this technological era, UV lights are
gaining increased popularity. This gives rise to the question; can UV lights protect us
from bacteria in ducts?
People use ultraviolet lights to disinfect the air and HVAC unit. Knowing its effectiveness
for the said purpose will define its worth.
Does Ultraviolet Lighting Effectively Kill Microorganisms?
For the past 100 years, ultraviolet lightning is a proven source of killing harmful
microorganisms like mould, viruses, and bacteria. Medical practitioners also use it for
treating skin infections. Hence, these lights are widely used in medical centres, eateries,
and grocery stores.
Apart from this, UV light is also highly effective in killing and disinfecting HVAC systems.
Research conducted at Duke University Medical Centre revealed that ultraviolet lighting
successfully killed 97% of the antibiotic-resistant bacteria and super germs. According to
Applied and Environmental Biology, the bactericidal UV radiation notably reduced mid-
air fungi in ACs.
Effectiveness on Coronavirus
UV bactericidal lights have the power to kill many kinds of germs. As per the USA Centre
for Disease Control and Prevention, UV radiation and humid heat are the most promising
sanitization methods. Testing is still in the initial stages, but positive results are
predicted.
Type of Ultraviolet Radiation Used in Heating and Cooling Systems
The type of UV radiation integrated into the HVAC units is Ultraviolet Radioactivity
Lights that can kill the COVID-19 virus. The Centre for Disease Control and Prevention
(CDC) advises that the intensity of the light and time duration impacts killing coronavirus
effectiveness.
Experts recommend that we must not take our health safety for granted. The best way is
to consider installing UV Light In Duluth, GA.

UV Light Variety for HVAC Unit
There are two types of UV radiation that are designed for disinfecting your HVAC system.
Some of the common names include cleansing lights, bactericidal lights, disinfecting
lights, and purification lights.
Coil Sterilising Lights
One of the most important components of an HVAC system is the indoor coil. It is a key
location where mould and bacteria can grow. The function of the coil is to condense
humidity from the air to dehumidify the surroundings while operating. As air moves over
the coil, dirt and debris tend to stick to the damp sides. This is an ideal place for mould
and bacteria growth that can spread through the air.
Coil UV lighting is the most frequently used HVAC sterilizing lights. Single-lamp and
dual-lamp models are available in the market.

Air Disinfection Lights
Air Disinfection Lights are integrated into the ductwork that transports air into the unit.
Their purpose is to kill mid-air germs and mould particles. Other variations include stick
and u-shaped lamps. Few of the HVAC disinfection lights are synchronized with the
blower motor.
Do-It-Yourself Installation
The majority of the ultraviolet lighting for HVAC systems is designed with a 110V power
switch. A few versions come with a magnetic mounting bracket that allows quick and easy
installation. The procedure needs to access the coil cabinet or air duct. You can use sheet
metal screws to fix the light that does not have a magnetic bracket or plug.
If you have basic knowledge of electrical equipment, then you can easily save installation
costs. You can follow the instructions provided with the light pack.
Extra Benefits
Bacteria and fungus cause two additional issues that include unpleasant odours or
accumulation of microorganisms. When this happens, the Air Conditioning unit is likely
to leak. This not only enhances the probability of mould and contaminants growth but
also causes water damage.
Is Ultraviolet Lightning for Heating and Cooling Unit Worth It?
When you plan to get, the bactericidal lights installed in the HVAC system. You will have
to bear four types of costs: fitting cost, installation cost, replacement cost, and energy
cost. The costs estimates are below:
Type FittingCost
InstallationCost
ReplacementCost
EnergyCost
Coil SterilizingLights
$60 – $285 $100 – $225 $10 – $60 $15 – $30
Air DisinfectionLights
$80 – $400 $150 – $295 $15 – $125 $15 – $30
The lamp life spans from 9 to 14 months for all famous brands. So, you can expect an
average spending of $15 – $50 each year for the new lamps. After choosing the lights, you
can expect $45 to $70 yearly on the energy cost. So, the question arises that is it worth it?
The answer is yes. The reason is that health is the most valued and expensive asset of
every person. If any of your household members suffer from respiratory issues, allergies,
viruses, or COVID-19, then these sterilizing HVAC ultraviolet lights are a must-have.

While HVAC lights can be a good solution, you should never ignore the system’s regular
cleanliness and maintenance. Some of the tips to follow include:
Getting your heater, air handler, and coil thoroughly cleaned by a professional
Sealing ducts to avoid infiltration of the germs
Consult your technician if a high-MERV filter is appropriate for your heater or air
handler. If yes, then get one installed.
Installation of a UV Coil Light can help prevent the bacteria and fungi growth within
the system
A UV air disinfection light can be helpful for serious ductwork issues
Timely replacement of AC filters is recommended
