CERTIFIED HVAC TECHNICIANS - AIR QUALITY EXPERTSHVAC UV Light

UV (Ultraviolet) light is a kind of electromagnetic radiation on the spectrum between visible light and X-rays. 

It is available in three kinds: UVA, UVB and UVC. 

While UVA and UVB rays are known for causing sunburn and skin damage, UVC reigns supreme as a germicide.

UVC light can attack the DNA of bacteria and viruses to kill them off.

UVC lights are used in your HVAC system to sterilize the air and internal surfaces, significantly improving the air quality of your home.

Because it kills microbes, UV lights make your home healthier for you and your family.

UV lights alter your HVAC system by attacking and killing dangerous microorganisms your traditional filters might not. 

In HVAC systems, there are two UV lamps:

Air Sanitizing UV Lamps:

Placed in your ductwork, the lights clean the air that enters your system. As the breeze moves by, UV light destroys airborne bacteria, viruses, and allergens, giving you clean air throughout your house.

Coil Sanitizing UV Lights:

Placed next to the evaporator coil, they dehydrate and avoid the spread of mold and bacteria on damp areas. 

Because the evaporator coil is prone to condensation, it offers the perfect breeding ground for microbes that interfere with the functioning of your system and its cleanliness. 

Keeping the coil clean keeps UV lights better air flow, heat exchange and save energy.

If you add UV lights, you’re not only purifying the air – you’re improving your HVAC system’s performance and reliability.

Your HVAC system will be equipped with UV lights that have multiple other advantages in addition to purer air:

Better Air Quality

UV lights kill as many as 99% of contaminating microbes, such as bacteria, viruses, spores, and allergens, making it healthier for you and your family.

Dissipation of odors

UV lamps digest volatile organic compounds (VOCs) that leave behind a stink from cooking, animals, smoking, or chemicals to make your house smell better.

Energy Efficiency

Your HVAC system runs better with cleaner coils and ducts. UV lamps deter microbial growth that blocks airflow and heat loss, saving you energy and costs.

Longer Equipment Life

Keep major parts like the evaporator coil clean; UV lights will wear down your equipment. That means fewer breakdowns, less work, and a longer-lasting HVAC system.

Reassurance

Being reassured that your indoor air is actively filtered can be reassuring, particularly for allergy sufferers, asthmatics, or those with compromised immune systems.

By putting in UV lights, you’re investing in your home’s health, energy and comfort.

UV lights provide many advantages, but there are risks:

Safe Information

Direct exposure to UV light damages skin and eyes. With the right installation from a trained technician, UV light is kept inside the HVAC system and is not harmful to you or your family.

Maintenance

UV bulbs fail in time and must be replaced every year or every two years to keep them effective.

Short Range

UV Lights kill microbes but not dust, pet dander, or other larger particles. You still have to clean your filters and ducts regularly to ensure proper air quality.

Please analyze all of these details and talk to an HVAC professional before deciding whether UV lights are the right choice for your particular situation.
