How Furnace UV Lights Can Improve Your Indoor Air

A furnace UV light, also known as a UV-C (ultraviolet-C) germicidal light or UV air purifier, is designed to improve indoor air quality. It uses ultraviolet light to kill or inactivate bacteria, viruses, mold and mildew.

These microorganisms may be present in the air or on the surfaces of your HVAC (Heating, Ventilation, and Air Conditioning) system components, particularly within the furnace or air handler.

Why Get a Furnace UV Light?

UV lights have many benefits, including:

Improved Indoor Air Quality: UV-C light effectively destroys or sterilizes microorganisms, reducing the concentration of airborne pathogens that can cause illnesses or allergies, improving overall indoor air quality.

Mold and Mildew Prevention: UV-C lights installed within the HVAC system can help prevent mold and mildew growth on the cooling coils, drain pans and other components, which can contribute to unpleasant odors and health concerns.

Enhanced HVAC Efficiency: By keeping the HVAC system components clean and free from microbial growth, the UV light can help maintain the system’s efficiency. Dirty coils and surfaces can reduce heat exchange and airflow, leading to decreased performance and increased energy consumption.

Odor Reduction: UV-C light can break down volatile organic compounds (VOCs), which are responsible for some unpleasant odors.

Extended Equipment Life: By preventing microbial growth and reducing the need for cleaning and maintenance, UV lights can potentially extend the lifespan of HVAC equipment.

Allergy and Asthma Relief: Cleaner indoor air, free from airborne allergens and pathogens, can be beneficial for individuals with allergies or respiratory conditions, potentially providing relief from symptoms.

It’s important to note that while furnace UV lights offer several benefits, they are not a standalone solution for indoor air quality. They are typically used in conjunction with other air filtration and purification methods, such as HEPA filters, for best results.

Proper installation and maintenance of UV-C lights are crucial for their effectiveness. If you are considering installing a furnace UV light, consult with reputable Cincinnati HVAC companies like the team at Jansen Heating & Cooling, who can assess your specific needs and ensure proper installation and maintenance.

How Much do HVAC UV Lights Cost?

The cost of furnace UV lights can vary widely depending on several factors, including

  • the type of UV system,
  • the brand,
  • the installation complexity and
  • the specific features included.

In-Duct UV Lights are installed directly into the HVAC ductwork. Prices typically range from $100 to $800 or more, depending on the quality and brand. The cost may also include installation fees if you hire a professional.

Coil UV Lights target the evaporator coils, preventing mold and microbial growth on the coils. These can cost anywhere from $100 to $500 or more.

Whole-House UV Systems combine in-duct and/or coil UV lights with air purification technologies. Whole-house UV systems with advanced features can range from $500 to $2,000 or more.

Portable or Room-Specific UV Air Purifiers can be placed in specific rooms. They can range from $100 to $500 or more, depending on the capacity and features.

These price ranges are approximate, and actual costs may vary based on the size of your HVAC system, the complexity of installation, the quality of the UV light system and your location.

These are January 2022 prices; your Cincinnati HVAC repair professional can provide more up-to-date prices for your area.

When considering the cost of a furnace UV light system, it’s essential to factor in not only the initial purchase price but also ongoing expenses like replacement bulbs or lamps, maintenance and any additional installation or professional service fees.
