Indoor air quality has become a major concern for homeowners in recent years. With most people spending approximately 90% of their time indoors, ensuring that the air you breathe is clean and healthy is more important than ever. At Refresh HVAC, we understand the importance of maintaining excellent indoor air quality, which is why we’re excited to share our expertise on UV light systems for furnaces and how they can significantly improve the air quality in your home.
UV light technology has been used for decades in hospitals and commercial settings to sterilize equipment and spaces. Today, this powerful technology is available for residential HVAC systems, offering numerous benefits that extend beyond just cleaner air. In this comprehensive guide, we’ll explore everything you need to know about UV light systems, their benefits, and why you should consider adding one to your furnace system.
What is a UV Light System for Your Furnace?
UV light systems for furnaces utilize ultraviolet light technology to sanitize the air and components within your HVAC system. These systems emit ultraviolet-C (UV-C) rays, which have powerful germicidal properties. When installed in your furnace or air handler, UV lights target and neutralize harmful microorganisms that might otherwise circulate throughout your home[2][3].
The science behind UV light technology is fascinating. UV-C rays work by penetrating the cellular walls of microorganisms and destroying their nucleic acid and DNA structure. This process effectively deactivates bacteria, viruses, and mold, preventing them from reproducing and causing harm to your health[3]. Since these microorganisms cannot build up resistance to UV light (unlike with chemical treatments), UV systems provide a consistent and effective method of air purification.
Types of UV Light Systems for HVAC Units
There are two main types of UV light systems used in residential HVAC applications:
Coil Sanitizing Lights
Coil sanitizing lights are strategically placed near the evaporator coil of your furnace or air handler. This cool, moist area is particularly susceptible to mold and bacteria growth. The UV lights target and kill these microorganisms, preventing them from building up on the coil surface. These lights typically remain on 24/7 for maximum effectiveness.
Air Sanitizing Lights
Air sanitizing lights function more like an in-duct air purifier. They’re installed within your ductwork to neutralize airborne pathogens as they pass through your HVAC system. These lights can be configured to turn on and off with your HVAC system, effectively treating the air each time your system operates.
The Top Benefits of Installing a UV Light System
1. Dramatically Improved Indoor Air Quality
UV light systems can kill up to 99% of bacteria, mold, viruses, and other harmful microorganisms that may be circulating through your HVAC system[9][11]. This significant reduction in airborne pathogens leads to noticeably cleaner, fresher air throughout your home[14].
2. Reduced Allergy and Asthma Symptoms
For those suffering from allergies or asthma, a UV light system can be particularly beneficial. By eliminating allergens like mold spores, pollen, and other irritants that may be harbored in your HVAC system, these lights can help reduce respiratory symptoms and create a more comfortable living environment for sensitive individuals.
3. Prevention of Mold and Mildew Growth
The dark, humid environment inside your HVAC system creates the perfect conditions for mold and mildew growth, especially on the evaporator coil. UV lights effectively prevent this growth by continuously sanitizing these surfaces, which helps maintain cleaner air and prevents the musty odors associated with mold growth.
4. Elimination of Unpleasant Odors
UV lights don’t just kill microorganisms; they can also help break down volatile organic compounds (VOCs) that cause unpleasant odors in your home. Whether it’s cooking smells, pet odors, or chemical fumes, UV light technology can help neutralize these odors at their source.
5. Increased HVAC System Efficiency
When mold and bacteria build up on your evaporator coil, they create a barrier that reduces heat transfer and restricts airflow. This forces your system to work harder, consuming more energy and potentially shortening its lifespan. By keeping the coil clean, UV lights can increase your system’s capacity by up to 35%, leading to improved efficiency and lower energy bills
6. Extended Equipment Life
With less strain on your HVAC system due to improved airflow and reduced microbial buildup, your equipment can operate more efficiently and last longer. This translates to fewer repairs and a longer service life for your furnace and air conditioning system[14].
7. Protection Against Illness
Especially relevant in today’s health-conscious world, UV light systems can help reduce the spread of airborne viruses and bacteria that may cause illness. By neutralizing these pathogens before they circulate through your home, UV lights provide an additional layer of protection for your family’s health[11][14].
Installation and Maintenance Considerations
Professional Installation is Critical
While UV light systems offer numerous benefits, proper installation is essential for safety and effectiveness. UV-C light can be harmful to skin and eyes, so these systems must be correctly positioned and shielded within your HVAC system. Our certified technicians at Refresh HVAC are trained to install UV light systems safely and effectively, ensuring optimal performance and safety
Regular Maintenance Requirements
Like any component of your HVAC system, UV lights require some maintenance to continue functioning at peak performance. The most important maintenance task is regular bulb replacement, typically every 12-24 months depending on the specific system. The bulbs will continue to emit light even after their effectiveness has diminished, so following the manufacturer’s replacement schedule is important[7].
During your regular HVAC maintenance appointments, our technicians will check your UV light system, ensure it’s functioning properly, and replace bulbs as needed. This proactive approach ensures continuous protection and optimal performance[11].

Our installation process includes safety measures to ensure the UV light is only exposed within the appropriate areas of your HVAC system.
How much do UV light systems cost?
The cost of a UV light system varies depending on the type of system, the size of your HVAC unit, and the complexity of the installation. While there is an upfront investment, many homeowners find that the long-term benefits—including improved health, reduced energy costs, and extended equipment life—make UV light systems a worthwhile addition to their HVAC system.

How long do UV light bulbs last?
Most UV light bulbs need to be replaced every 12-24 months, depending on the specific system and usage. While the bulbs may continue to emit visible light beyond this period, their effectiveness at killing microorganisms diminishes over time. Our maintenance plans include regular bulb replacement to ensure continuous protection.
