The Impact of UV Light on Your HVAC System and Your Health


The air we breathe has a significant impact on our health, and as we spend more time indoors, it's essential to ensure that the air quality is of the highest standard. One factor that can impact both the HVAC system and our health is UV light. While UV rays are well-known for its role in disinfecting surfaces, it can also be used to improve the air quality in your home or business.


In this blog, we'll take a closer look at the impact of UV light on your HVAC system and your health and explore how you can benefit from this technology.


How UV Light Works in HVAC Systems


UV light is used in HVAC systems to sterilize the air and promote cleaner indoor air. Harmful particles and microorganisms are eliminated after extended exposure to UV radiation. The most common types of UV light used in HVAC systems are UV-C and UV-V. UV-C light has a wavelength between 100-280 nanometers, which is effective in destroying microorganisms, while UV-V light has a wavelength between 280-400 nanometers, which is effective in breaking down volatile organic compounds (VOCs) and reducing odors.


UV-C light is commonly used in HVAC systems to eliminate airborne bacteria and viruses, while UV-V light is used to reduce odors and improve indoor air quality. Common viruses like the coronavirus are among those that can be killed with ultraviolet radiation.


The Benefits of Using UV Light in HVAC systems:

  • Reduce the spread of illnesses by killing viruses and bacteria in the air.

  • Reduces mold and mildew - It can prevent the growth of mold and mildew in the HVAC system, which can cause health problems.

  • Improves energy efficiency - UV light can improve the efficiency of the HVAC system by reducing the buildup of dust and debris on the coils.

  • Eliminates odors: UV-V light can improve indoor air quality by breaking down volatile organic compounds (VOCs) that cause odors.

  • Reduces allergies and asthma - UV light can reduce allergies and asthma symptoms by eliminating airborne allergens, such as pet dander and dust mites.

  • Helps prevent sick building syndrome - UV light can improve indoor air quality and reduce symptoms such as headaches, fatigue, and respiratory problems by eliminating pollutants that cause sick building syndrome (SBS).

The Impact of UV Light on Indoor Air Quality


Indoor air quality is critical to our health, as we spend a significant amount of time indoors and with air conditioning systems. Poor indoor air quality can lead to respiratory problems, allergies, and other health issues. UV light helps to improve indoor air quality by eliminating harmful particles and microorganisms.


Examples of pollutants that can be eliminated with UV light include mold spores, bacteria, viruses, and pet dander. These pollutants can cause allergies, asthma, and other respiratory problems, so eliminating them from the air can have a significant impact on our health.


The Impact of UV Light on Health


UV light can have a positive impact on our health. Studies have shown that UV light is effective in reducing the spread of viruses and bacteria. In a hospital setting, UV-C light is used to disinfect surfaces and equipment to reduce the spread of illnesses. UV-C light can also reduce asthma and allergy symptoms by eliminating airborne allergens, such as dust mites and pet dander.


Choosing the Right UV Light System for Your HVAC


There are many types of HVAC systems and choosing the right UV light system for your HVAC is essential to ensure that it is effective in improving indoor air quality. Factors to consider when selecting a UV light system include the size of your HVAC system and the type of UV light needed. UV-C light is most effective in killing bacteria and viruses, while UV-V light is effective in reducing VOCs and eliminating odors.


There are different types of UV light systems available, including in-duct, coil-mount, and portable units. In-duct units are installed in the HVAC system, while coil-mount units are mounted directly on the coils. Portable units are standalone units that can be moved from room to room. The type of unit you choose will depend on your specific needs and the size of your HVAC system.


With so many types of heating and cooling systems such as central and mini split AC systems, be sure to choose the right UV light treatment system for your property.
