HVAC units control your indoor temperature, your home’s airflow, and indoor humidity levels. They can also improve indoor air quality by using strategically placed filters to catch dust and dirt. However, air filters may not be enough for many homes. For example, these aren’t effective against microscopic viruses and bacteria. These pathogens can be distributed throughout your home, compromising the health of the occupants. Consider improving it by installing a UV light for HVAC system.

Ultraviolet light is outside of the visible spectrum. We can’t see it, but the effects of this high-frequency radiation can be felt. Around 10% of sunlight is UV rays. This can be generated artificially with electronic machines like UV lights for air conditioners and furnaces.
Types of UV Lights
Here are three types of UV lights:
- UV-A creates the longest wavelength and poses the least danger to people. However, exposure to it for prolonged periods is still unhealthy. Applications for this type include anti-theft protection, banknote inspection, and stage installations.
- UV-B has a shorter wavelength and higher frequency than UV-A. It can cause harm to your skin when exposed, but it doesn’t penetrate deeper. The medical industry utilizes it to cure skin ailments like psoriasis and eczema. Investigators also use it for DNA analysis. They are also used in bug-zapping devices, as UV-B bulbs attract bugs.
- Of the three, UV-C has the shortest wavelength and highest frequency. The good news is the ozone layer protects us from it. Scientists discovered it could kill germs in the 1800s. As a result, the manufacturing industry uses it for disinfection, sanitation, and sterilization. UV-C rays are also utilized in many water treatment plants.
How UV Lights Work to Kill Bacteria & Viruses?
Ultraviolet light can penetrate the microorganisms’ outer layer and destroy their DNA at the cellular level. When this happens, viruses and bacteria lose their replication abilities. Others die right away upon exposure. Prevent the spread of disease in your home by installing UV lights in HVAC systems.

Benefits of Using UV Lights in HVAC Systems
Here are some of the pros of using UV lights in HVAC systems:
Improved Air Quality And Reduced Risk Of Airborne Illnesses
The US Environmental Protection Agency states that indoor air has twice to five times more pollutants than outdoor air. Pay attention to indoor air quality to lower the risk of airborne illnesses in your household. UV lights can destroy most pathogens circulating in your HVAC unit. It has an instantaneous effect that you can feel immediately.

Increased Energy Efficiency & Cost Savings
HVAC coils that are thick with microorganisms can’t work well. The reduced airflow causes inefficiency, forcing the system to operate longer and use more energy. UV lights kill these microorganisms. Clean the coils after exposing them to UV to enjoy better efficiency and promote good airflow. The long-term savings can make up for the cost of the UV lights.
Reduced Maintenance & Prolonging The Lifespan Of HVAC Equipment
Air conditioners blow hot indoor air across cold coils to lower the temperature inside your home. A side effect of this method is humid air condensation. Engineers anticipated this to happen, so they equipped the system with a condensate drain line to move the water out of the system. The bad news is that algae can grow and block the path. Mold can also grow along the coils. Therefore, cleaning frequently is necessary. UV lights prevent these microorganisms from developing in the first place. This helps reduce the upkeep work and equipment damage. They also help extend your system’s lifespan.
Is the air coming out of your air conditioner accompanied by a foul smell? It can worsen as time passes until you can’t ignore it anymore. It can also be a source of shame when visitors drop by. The foul smell is likely because of the growth of bacteria in the system. Get rid of the smell by opening your system and cleaning its interior. However, this is only temporary because it can happen again unless a permanent solution is implemented. An example is putting UV lights. Their rays will destroy the bacteria and keep them from generating a foul odor, so your home always smells fresh and clean.
How to Install UV Lights in HVAC Systems
Installing UV lights may seem straightforward, but many considerations must be made when adding them to your HVAC equipment. Keep reading to learn more about this.
Types of UV Lights Suitable for HVAC Systems
Here are two types of UV lights that are best for HVAC systems:
- Coil-sanitizing Lights: These units focus on the air handler’s evaporator coil. The coil surface is always moist because of condensation. This makes it an ideal environment for bacteria and fungi to thrive. Coil-sanitizing lights can eliminate them before they have a chance to grow.
- Air-sanitizing Lights: If you own a central air conditioner, place the UV lights in the air supply vents across the ducts. Putting the light in this position lets them sanitize the air directly before it is distributed throughout the home.

Professional HVAC UV Installation Process
You may try to install the lights, but improper installation can cause poor performance and system damage. Hire a certified professional to install them, so you are assured of system integrity and exceptional results. Professionals know how to choose the best locations to ensure adequate disinfection and harm reduction. Pros can also clean the ductwork and repair leaks before installing the UV lights.
Maintenance & Upkeep of UV Lights
The lights will do their job in the background around the clock. You don’t need to concern yourself about them constantly, but they require regular upkeep. Wipe the dirt on the surfaces and replace the lights if needed. Don’t touch the lamp’s surface, as the oil from your palm can reduce UV output. Wear eye protection when you get close to them. Call HVAC professionals to help you with the maintenance if you are wary about the dangers of UV radiation.
