In recent years, using ultraviolet (UV) light in HVAC systems has become more common in homes and workplaces. The technology is now more accessible and is no longer confined to hospitals and big establishments, which is great news for homeowners and small entrepreneurs.
HVAC ultraviolet light is an effective way of boosting indoor air quality and keeping the air we breathe cleaner and free from germs and viruses that cause allergies and sickness. Find out how it works and why you should have it installed in your space.
The Type of UV Light Used in HVAC
Different types of UV light have different effects. You might have heard of UV-A and UV-B rays, which sunscreens and sunblock protect us from. The UV light used in HVAC is UV-C, which has short, intense bursts of light with germ-busting capabilities. UV-C destroys bacteria’s DNA, so the germs cannot replicate (some die right away).
Where UV Light Is Installed and How It Works
- Inside the ductwork or air handler of an HVAC system: Air-sanitizing UV lights help kill the microorganisms that are airborne, such as mold spores and viruses. This reduces the harmful contaminants that circulate in the air.
- Near the indoor evaporator coil of an air-conditioning system: Coil-sanitizing UV lights work by shining directly on the coil surface. This prevents the buildup of mold and bacteria caused by the moisture collected in the evaporator coil.
- Above the condensate pan in air conditioners: Condensate pan UV lights help sanitize the pan, which collects moisture drained from the evaporator coil. This prevents the area from growing bacteria and mold, which can be caused by stagnant water from the dampness.
On Protection and Safety
UV light in HVAC is designed to be safe for use in any type of space, with proper containment and shield. However, safety precautions still need to be followed, from installation to maintenance and handling.
Direct exposure to UV light should be avoided at all times, as it can damage the eyes and lead to health issues. This includes never looking directly at an active UV light. Additionally, protective gear, such as glasses and gloves, must be worn when handling UV bulbs. For safe implementation and maximum results, you should only let qualified HVAC technicians install and service the bulbs.
Choosing the Right UV Light for Your Space
This depends on the size of your HVAC system, airflow rate, and the level of disinfection that you want. In some cases, a combination of the different types of UV lights is used for optimum results. Remember that consulting with a licensed and reputable HVAC professional is essential to help you determine the appropriate type of UV light and its compatibility with your specific system.
The Lifespan of UV Bulbs and Their Maintenance Requirements
UV bulbs can last from one to five years, depending on the model and manufacturer. Their effectiveness diminishes over time, so regular replacement is required. However, you may need to contact your trusted HVAC technician sooner to replace the bulb if you notice that it is not working properly or if the indoor air quality becomes poor.
Is Investing in HVAC UV Light Worth It?
UV bulbs are one of the best upgrades you can make because of the benefits they provide. When you have these installed, you can have peace of mind that you have additional protection from airborne microorganisms because of the power of UV light to destroy them as they pass through your HVAC system.
Apart from eliminating bacteria and reducing the risk of illnesses in your household or office, they help get rid of odors because of the cleaner air that circulates.
Improve the Air Quality in Your Home or Workplace
Since we spend most of our time indoors, it makes sense to prioritize the quality of the air we breathe. This means making sure our spaces have cleaner and fresher air all year round. We can achieve this by utilizing UV light technology and combining it with other practices and strategies.
