Are UV Lights Worth It for HVAC Systems? - A Comprehensive Guide

Ultraviolet (UV) lights are an effective, easy-to-maintain, and cost-efficient solution for anyone with a home air conditioning system. Even if your air conditioning system has a high-quality air filter, adding a UV light can help eliminate microorganisms and bacteria that might be too small to be filtered out. A study conducted in 2001 by the American Society for Microbiology showed that spiral disinfectant lights dramatically reduced the amount of live fungi in an office air conditioning system. UV HVAC lights are designed to remove potentially harmful compounds, such as mold and bacteria, from the home air.

With the right conditions and proper installation, UV lights can be very effective in eliminating viruses, mold, and bacteria. The coil sterilization lights are installed so that they can shine directly on the surface of the coil and are left on continuously. While UV light can help people with respiratory problems by destroying mold and mildew formation, HVAC UV lamps are expensive to install and maintain and will ultimately make it necessary to repair the HVAC system due to damage caused. A professional with experience installing UVGi systems must consider a multitude of conditions when installing a system.

HVAC UV lights don't remove dust or dandruff from the air circulation, so you may need to look into other solutions if this is your problem. However, installing an HVAC UV air purifier could be a proactive step for those who live in humid and humid climates. For example, symptoms of black mold in an air conditioner include headaches that go away when you are outside, coughing, sneezing, skin rashes, nausea and fatigue, and UV lights can prevent problems like this from the start. In addition to eliminating mold and bacteria from the air circulation, UV lights also help keep the coils and the drain pan clean, reducing both wear and maintenance requirements. A complete UV light unit is connected directly to the air ducts to disinfect the air entering the machine.

The CDC warns that the lights are more or less effective depending on the intensity of the UV rays and the time the contaminated surface is exposed to light. Whether you want to maximize the efficiency of your air conditioning system or keep the effects of allergens away, a UV lamp is a smart long-term investment. Adequate air filtration is still necessary to remove particulates such as dust and dandruff from the air before they circulate around the house. Between the two models of UV light for air conditioning, the “best option” depends on the system and the needs.
