Do HVAC UV Lights Get Hot?

Ultraviolet (UV) HVAC lights are an effective way to remove potentially harmful compounds, such as mold and bacteria, from the air in your home. On average, these lights reach about 50 degrees Celsius (122 degrees Fahrenheit), which is not as hot as an incandescent bulb. Installing UV lights in your air conditioning system is simple, although most people should leave it in the hands of a professional. High-frequency UV light has enough energy to destroy the DNA of bacteria and other microorganisms, killing them and disinfecting the air.

This can help prevent the occurrence of problems such as headaches that go away when outside, coughing, sneezing, rash, nausea, and fatigue. In addition, UV lights can limit mold growth throughout the HVAC system and prevent certain respiratory diseases. Between the two models of UV light for heating, ventilation and air conditioning systems, the “best option” depends on the system and the needs. A more complicated system with lights mounted on all ducts will be better for keeping the system clean, but installing them is more difficult and expensive. Most UV HVAC lamps are designed to be able to draw energy from the fan, so that they only work while the air controller is turned on. UV bulbs work less effectively when they're covered in dust, so you'll need to clean them quite often to make sure this never happens - about once every two months, and possibly more if you live in a particularly dusty place.

We recommend that you add a reminder to replace UV light to your air conditioning maintenance checklist, so you don't forget it. While it's true that UV light can damage some materials, you don't have to worry about a UV lamp damaging your air conditioning system. In addition, both types of disinfectant lights prevent dirt from accumulating and moving through the air conditioning system. A 2001 study conducted by the American Society for Microbiology showed that spiral disinfectant lights dramatically reduced the amount of live fungi in an office's air conditioning system. While their cleaning power is not visible to the human eye, several studies suggest that UV lights kill germs at a rate raised. If you're looking for an effective way to keep your home's air clean and healthy, consider installing UV HVAC lights.
