The Benefits HVAC UV Lights 101 & Harzards Of UV Lights – Tim & Sons Heating Cooling HVAC Contractor in Fairfax, VA

UV light or ultraviolet light is a form of electromagnetic radiation that is given off by the sun. Ultraviolet light waves occupy the 0 nm to 400 nm range within the light spectrum. This range is optically invisible to the human eye. This is what gives you a sunburn after a long day at the beach.


Benefits of HVAC UV Light

– UV light is very dangerous if you are overexposed to it. Here are some of the bad things UV light does to people:

– However, UV light has more good uses than bad effects. UV light is used in the field of medicine, food and drugs, and even in the HVAC field because of its sanitation and disinfection capabilities. It is very helpful when putting into the right use.

– You need to incorporate UV light into your system because of 2 things: mold and bacteria. These two things are not to be ignored. This unwanted contamination will, more often than not, be the bearer of harmful viruses and diseases such as allergic rhinitis, asthma, and pneumonia. These contaminants can also emit a foul-smelling odor that is very unpleasant.

– Damages immune system- Sunburn can change the distribution and function of disease-fighting white blood cells in humans for up to 24 hours after exposure to UV rays. – To reduce and remove illness-causing viruses and make sure that germs are not re-circulated by your HVAC system


– Damages the eye- Overexposure of the eyes to UV causes a condition called ‘snow blindness’ or photokeratitis. – To get rid of foul-smelling odor caused by bacteria


– To remove harmful, volatile organic compounds such as benzene, ethylene glycol, and formaldehyde

Coil sterilization and Air Sterilization

HVAC UV lights serve two different purposes. These are “Coil sterilization”, and “Air Sterilization”.

Coil Sterilization

Air Sterilization

– Coil sterilization is when the HVAC UV light is used to prevent and destroy microbial growth from growing onto the coil.

– A stick-type UV light bulb is placed inside near the return air duct. This sterilizes the air handler coil and provides 24/7 sterilization. This is the most common type of HVAC UV light used and is reasonably priced.

– Air sterilization uses a complete UV light unit that sterilizes moving air. Air sterilization is done by treating the contaminants in the airstream, which may be moving at a pace of hundreds or thousands of feet per minute.

– The UV light unit is installed in the return air duct and runs cycles with the air handler blower.

A well-known brand of UV light bulbs is estimated to run for 9000 hours, approximately a little over one year and replacement.
