The bacteria buildup can also harm your HVAC system. This makes the coil less effective, which means your home isn’t as comfortable as it could be. When the evaporator coil builds up too much moisture and bacteria, it can corrode. Since the coil comes in frequent contact with the liquid refrigerant and the bacteria in the HVAC system, it’s a breeding ground for germs. The evaporator coil holds the liquid refrigerant that cools your home. Inside the air handler is an evaporator coil. In an air conditioner or furnace system, the air handler is the component inside your home. They are the more common and less expensive of the two varieties. Coil sanitizing lightsĬoil sanitizing lights look like long, thin fluorescent lamps. If you don’t have central HVAC, alternatives like air purifiers or air scrubbers are worth checking out. Note that you need a central HVAC system to use either variety of light. Coil sanitizing lights are great at keeping your HVAC system clean, but air sanitizing lights do the best job of cleaning the air itself. Still, they differ in ways that could impact your buying decision. Both work effectively and can help promote cleaner air. HVAC UV light model typesīetween the two models of UV light for HVAC, the “better” option depends on your system and needs. Air sanitizing lights are placed in your return vents, which are part of your ductwork. Coil sanitizing lights sit near your evaporator coil. There are two varieties of UV sanitizer lights. When bacteria or mold’s DNA is damaged, it will either die or become unable to reproduce. Once the germs are exposed to the light, they absorb the light’s UV rays. When germs move through the central air system, they eventually make it to the sanitizing light. UV light for HVAC systems is installed either in your air handler or in your ductwork. UVC rays have the highest energy of the three, and they are the only rays powerful enough to kill microscopic germs. The third variety, UVC, is used in HVAC lights and lasers. When you put on sunscreen, you’re blocking out UVA and UVB rays. There are three types of UV radiation: UVA, UVB, and UVC. In the 1930s, hospitals used these lights to treat conditions like tuberculosis. UV lights may look like futuristic lightsabers, but they’ve been used for almost a century. They are commonly used in both home and commercial spaces. What is an HVAC UV Light?Īn ultraviolet (UV) light emits powerful rays of energy that kill bacteria, fungi, and viruses. An HVAC UV light helps you stay healthy by sanitizing the air moving through your HVAC system, reducing the mold and viruses distributed into your home’s air.

Indoor air quality is an important piece of the home comfort puzzle.
