How long do ac UV lights Last?
Usage of the HVAC system ultimately determines how often you should replace the UV lights in your air purification units. We recommend changing your UV germicidal light at least every 12 months to maintain a clean, healthy environment. Lamp life is generally 6 to 12 months for most brands.
Does UV light damage HVAC?
If installed incorrectly, UV lights can damage some parts of the HVAC system.
Does a UV light go in the supply or return?
Ultraviolet lamps can be easily added to an existing forced air system. Lamps can be installed either in the main supply or return duct of a central heating or air system. The best installation location for a UV lamp is downstream of the air conditioning coils on the supply side of the heating/cooling system.
How much does UV light cost?
How Much do UV Lights Cost?
| Type | Light Cost | Installation Cost |

How often should you replace a UV bulb?
Typically, a UV lamp being used primarily to disinfect the air circulating through a home or small office should be replaced every 9000 hours or approximately every 12 months.
Do UV lights lose their effectiveness?
Like your average light bulb, UV lights have a finite life span that requires them to be changed on a regular basis. As these lights operate, they slowly lose their effectiveness as a germicidal agent by about 15 percent each year.
Do HVAC UV lights create ozone?
EPA: According to two studies, operating UV lamps installed in HVAC systems to irradiate the surfaces of air-handling units does not result in increased concentrations of ozone.
Do UV lights wear out?
UV lamps should be replaced once every 12 months. UV lamps have a lifespan of approximately 9,000 hours. Calculated out, this means the lamp can operate for about 375 days before requiring a replacement.
Do HVAC UV lights smell?
In short, the use of these lights is not hazardous inside the system and any metallic odors you smell may be the result of the production of ozone gas by the UV-C lights.
Are UV air purifiers worth it?
Short answer: No. Don’t buy a UV light air purifier or any air purifiers that use UV light as a key part of their purification mechanism. It’s dangerous and doesn’t work that well, especially without the use of other proven air filtration methods.

What are the benefits of UV light?
The three primary health benefits of UV exposure are the production of vitamin D, improvement in mood, and increased energy. Moderate exposure to UV radiation is a good source of vitamin D. This vitamin aids in the regulation of calcium metabolism, insulin secretion, blood pressure, immunity, and cell propagation.
Where is UV light found?
UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights.
Do UV lights use a lot of electricity?
Currently, most of these lamps operate at 300 to 600 watts per inch with some newer systems using lamps that generate up to 1000 watts per inch. So a 30 inch UV bulb may be capable of an output of 30,000 watts. They also operate at very high temperatures (850 to 950 Celsius or 1550 to 1750 Fahrenheit).
Are UV lights expensive?
There is a wide range of products on the market right now, and they vary greatly in cost. A UV-C fixture can cost you anywhere from $150 to $20,000.
Is ozone from UV light harmful?
Understand the potential risks from exposure to excessive amounts of ozone gas or UV light as described below include irritation to breathing passages (that is nose, throat, and lungs), particularly for those who have respiratory sensitivity such as asthma or allergies.
Can you touch a UV bulb?
Avoid touching or scratching the glass section of the lamp. Fingerprints weaken the lamp envelope, and this may lead to lamp explosion. Do not touch the lamp while working.
How much does it cost to replace a UV bulb?
The cost to replace each lamp is about $85. The ballast comes a 10-year warranty and the replacement cost is about $80. Plus, you are reducing other maintenance and cleaning costs on the system.
How do you clean a UV light?
