Benefits of Installing a UV Light in your HVAC System

Updated: Mar 14, 2023

Ultraviolet lights are known for their ability to kill many types of bacteria. During the pandemic, people realized the importance of the effects of UV light in reducing harmful bacteria. One tactic to improve indoor air quality that many homeowners don't know much about is installing ultraviolet HVAC lights.

There are several different types of UV light, but we are talking about UV-C band. UV-C light is the most effective wavelength of ultraviolet light for killing bacteria and germs. Aero germicidal HVAC lights work within the UV-C spectrum, making them the best for air purification and safe removal of bacteria and viruses. Ultraviolet germicidal irradiation can be very useful in a residential HVAC systems, preventing the circulation and accumulation of microorganisms in the home's ductwork.

There are two different mounting/install locations for HVAC UV lights: on the blower fan and on the coil. Blower (fan) sterilization utilizes UV-C light to disinfect the air circulating through the return vents. When sterilizing the air, UV-C light uses the reflective surfaces of the ducts to maximize efficiency. Sterilizing coils involves placing UV-C lamps in problem areas such as condensation pans and AC coils. This reduces microbial growth in hard-to-reach places such as fins, grooves, and corners.

Illness Prevention

Probably the biggest benefit of UV lights in your HVAC system is their ability to limit the spread of disease and sickness. As your cooling system circulates air throughout your home, it can spread airborne germs, bacteria, and viruses. UV light kills bacteria, viruses, mold, mildew and other toxins and allergens. The thought of having moldy, dirty air circulating in your home and ducts is a less than a pleasant thought. The UV lights in the air conditioner can improve indoor air quality and prevent your family from getting sick from sterilization.

Better indoor air quality

UV lights kill airborne allergens and bacteria in the air, improving your indoor air quality. This is a big advantage, especially if someone in your home suffers from allergies or breathing problems such as asthma. In addition, smaller children and the elderly may be more susceptible to respiratory problems due to poor air quality.

Improved energy efficiency

Installing a UV lamp in your HVAC system can reduce your home's total energy use by up to 35 percent. UV lights alone do not reduce the energy consumption, but rather they work to restore the HVAC system's performance to optimal levels, which in turn reduces energy consumption by helping the system run like new. Even if your HVAC system has a UV light, you need routine maintenance visits to make sure everything is working properly.

Profitable investment

Before installing HVAC UV lights, a professional should evaluate your home's system to ensure it is a profitable investment. If they find that LVI UV lights are right for you, it can be a very cost-effective investment. Most of the time, the investment prioritizes your family's health, saves you money, and restores your system to increase efficiency and improve the condition of your HVAC system.

All of these advantages of HVAC UV are undoubtably a considerable investment. Contact a professional today to evaluate your HVAC system and see if installing a UV light is an advantageous and affordable decision for your home.
