HVAC systems are not just there to control indoor temperature. They also manage humidity and airflow. They can even improve indoor air quality through strategically located filters for dust and dirt. However, for many, these air filters are not sufficient. These are ineffective against microscopic bacteria and viruses. These pathogens can circulate in the home and compromise health. Improve your HVAC system by considering a UV light for HVAC system.

What Are UV Lights?

Ultraviolet light is just outside of the visible spectrum. We cannot see it, but we can feel the effects of this high-frequency radiation. Approximately 10% of sunlight is UV rays. We can also produce it artificially with electronic devices, such as UV lights for furnaces and air conditioners.

Types of UV Lights

  • UV-A produces the longest wavelength and the least amount of danger to humans. However, prolonged exposure is still unhealthy. Applications include banknote inspection, stage installations, and anti-theft protection.
  • UV-B has a shorter wavelength and higher frequency than UV-A. It can harm the skin upon exposure but cannot penetrate deeper. The medical industry uses it to cure conditions such as eczema and psoriasis. Investigators apply it for DNA analysis. UV-B bulbs attract bugs, go you can find them in bug-zapping devices.
  • UV-C has the shortest wavelength and highest frequency of the three types. Fortunately, the ozone layer blocks it for us. In the 1800s, scientists discovered its ability to kill germs. The manufacturing industry uses it for sanitation, disinfection, and sterilization. Many water treatment plants also utilize UV-C rays.

How UV Lights Work to Kill Bacteria & Viruses?

Ultraviolet light can penetrate the outer layer of microorganisms and destroy their DNA at the cellular level. When this happens, bacteria and viruses lose their ability to replicate. Others die immediately upon exposure. By installing UV lights in HVAC systems, you prevent the spread of disease in your home.

Benefits of Using UV Lights in HVAC Systems

1. Improved Air Quality And Reduced Risk Of Airborne Illnesses

According to the EPA, indoor air contains 2 to 5 times more pollutants than outdoor air. Pay attention to indoor air quality to reduce the risk of airborne illnesses for you and your family. UV lights can destroy most of the pathogens circulating in your HVAC system. The effect is instant. You can feel the change right away.

2. Increased Energy Efficiency & Cost Savings

HVAC coils choked by microorganisms cannot work well. The reduced airflow makes them inefficient, forcing the system to run longer and consume more energy. UV lights kill the menace. Just clean the coils after exposure to promote good airflow and enjoy increased efficiency. The long-term cost savings can make up for the price of the UV lights.

3. Reduced Maintenance & Prolonging The Lifespan Of HVAC Equipment

Air conditioners lower room temperature by blowing hot indoor air across cold coils. One side effect of this strategy is the condensation of humid air. Engineers anticipate this, so a condensate drain line moves the moisture out of the system. However, algae can grow and clog the path. Mold can also spread on the coils. These make frequent cleaning necessary. UV lights prevent the growth of these offending microorganisms and reduce maintenance work. They also avoid equipment damage and prolong the system’s lifespan.

4. Eliminate Odors

Does the air from your air conditioner smell foul? It can get progressively worse until it becomes hard to ignore. It can even be a source of shame if visitors come by. The foul odor is probably due to bacterial growth inside the system. You must open it up and clean the interior to stop the stink. However, this is only a temporary solution. The same situation can happen again unless you find a permanent fix, such as UV lights. The rays will destroy bacteria and prevent them from producing a foul odor. Your home will smell clean and fresh.


How to Install UV Lights in HVAC Systems

Installation may seem straightforward, but there are plenty of considerations when adding these units to your heating, cooling, and ventilation equipment. Read on to learn more about it.

Types of UV Lights Suitable for HVAC Systems

  1. Coil-Sanitizing Lights: These units focus on the evaporator coil inside the air handler. The coil surface is perennially moist because of condensation, creating an ideal environment for fungi and bacteria. Coil-sanitizing lights can zap them before they get a chance to grow.
  2. Air-Sanitizing Lights: If you have central air conditioning, place these lights in the air supply vents across the ductwork. This positioning allows them to sanitize the air directly before circulation.

The lights will do their duty in the background 24/7. You do not need to worry about them constantly, but they will require regular maintenance. Wipe the dirt on their surfaces and replace the lights if necessary. Do not touch the lamp surface because the oil from your palm can decrease UV output. Wear eye protection whenever you come close to them. If you are wary about the dangers of UV radiation, call HVAC professionals to help you with the upkeep.
