HVAC Sanitizing & UV Light Purification

You’d most likely need sanitizing services if someone in your household has common respiratory problems like asthma or seasonal allergies. The symptoms of these issues create extreme discomfort, with heavy sneezing, running noses, blocked air passages, itchy eyes and nasal passages, and difficulty sleeping. These can be alleviated by eliminating high levels of contaminants from the air.  

Sanitization is crucial for those with compromised immune systems. Sanitizing your home’s heating and air conditioning equipment is relatively simple. It can be performed as part of regular duct sanitizing, dryer vent cleaning, or routine HVAC tune-ups completed in the fall and spring. 

Corley Pro recommends that HVAC equipment sanitization be done once annually in Greenville, about the same time your air conditioner coils get cleaned.

The sun produces UV light, or Ultraviolet light, a naturally occurring light wavelength. When you go outside, you are bombarded with these UV rays, and if you are exposed to them for too long without protection, you get sunburned. UV light is less stable than light we can easily see and often causes damage to both living and inorganic materials. It causes cell damage, and with time it burns your skin. 

The effect happens much more quickly for single-cell organisms like bacteria or viruses, with nearly instant cell destruction. This makes UV light very effective for killing microbial pathogens in your ductwork. 

UV Lights are generally installed in one or two main locations. The first is the air conditioning unit’s condenser coils. These coils hold refrigerant and pull humidity out of the air. This moist area is a breeding ground for mold and bacteria. 

The second area is in your supply vents, in the ductwork of your central HVAC system. UV lights here sanitize the air before it gets circulated throughout the home. The small apparatus is installed and kills bacteria and viruses as they pass. The UV light has been tested to find the right wavelength to be effective against microscopic bacteria and viruses, especially when concentrated in a confined space. 

The UV system needs to be accessible for maintenance, so it is usually placed in a junction that is easy to get to in the future. Because it’s usually located near the air handler, there is usually room to install it. 

If you are tired of having microbial bacteria, viruses, dust mites, and mold spores floating around in your home, using your central air system has a highway, call Corley today.
