- Here is a free checklist if you think you may have a mold problem:

UV Lights in HVAC systems can kill mold and bacteria but it's not the magic light that some air conditioning professionals make it out to be. Just being used on the air handler can improve the air quality in the home by keeping the system clean. Air duct cleaning will often not be necessary in a UV light is installed.
UV lights have other functions in the medical field that can help sanitize surfaces. Watch the video to learn how to properly use UV lights in HVAC systems

Interesting. Here in Japan, almost all rooms in the house have an air conditioner so this was useful to know. Cheers.
Really useful video. Learnt alot about UV light, and the benefits and drawbacks against mold
Good info, I will check out the checklist. Thanks
Did not realize this, many thanks!
Appreciate the slo-mo @:54 LOL
Wow! I knew UV lights could kill bacteria, but I had no idea they killed mold.
Thank you!
We don't have air conditions in the home here in the UK but great to know.
just buy a U.V bulb mate...use when nobody in the room obvs cheers
My current home is filled with mold. It is causing so many issues. We live in a manufactured home from the 70's and we constantly have standing water under the house so the floor keeps rotting out and the walls have mold in them and there is mold in the air vents. We plan on tearing down this house and rebuilding a new one with a concrete foundation. I want to do what ever I can to protect my family from mold in the new home so I do plan on getting the uv lights for the air system. Now I know I'll need to do other things to keep it from forming in the rest of the house. Thanks for the info
Pretty common sense here. "I don't have to clean my bathroom, i had a uv light installed! " 😜
YOu sound like Trump. You still have to clean.
@@richmanwalking5965 lol do you still have TDS?
I don't have Trump Down syndrome @@driftinaz3158. Since I know how it works, that was a stupid statement. By the way, I don't talk to people who hear to respond. In short, I don't talk to people who are not thinkers.
@@richmanwalking5965 ^^ this is the response a "thinker" with Trump derangement syndrome gives in 2021 btw .. maybe you should think more about how homophones work.
Pretty commom sense, u dont need to drain ur septic tank, u just have to put uv lights hehe
I have one that does UV and Ozone. But I'm having to rig up some UV on my fan compartment where mold has returned to. Where as the coils are still mold free so that part works
Will the lights kill existing mold in vents and plenum to the degree that the vents can be cleaned without spreading mold into the home ?
Why would a UV Lamp not be on all the time?
Does mold magically stop multiplying when the indoir fan shuts off??
Wouldn't it be benficial to keep the UV Lamp on 24/7 so that mold doesn't have the opportunity to multiply when the thermostat is satisfied?
...& some people seem to think that the UV Lamp can kill all virus mold & bacteria in the indoor unit &/or the supply air plenum...
...why couldn't it?
UV radiation type C, for example, is a pretty high frequency....& its moving AT THE SPEED OF LIGHT.
The viruses, mold & bacteria caught in the air stream are not moving anywhere near the speed of light.
So its kinda like a slug trying to out run a fighter jet...yeah.
Now, it IS possible that the wave-length of the UV Radiation could be too big to actually interact with stuff as smal as individual virus & bacteria...that could be the case.
But this ridiculous believe that being caught in the air stream, let's viruses, mold & bacteria "escape" the clutches of the UV Radiation.....is just dumb.
& for the record, that bluish glow, that the Lamps give off, is NOT the UV radiation. UV radiation is beyond our visible spectrum.
I'm going to guess that that bluish glow from the UV Lamp might be ionization either inside the lamp, or in the vicinity of the air just around the lamp.
Agreed. I placed mine in the cold air return just prior to filtration. Slower air movement, and am focused on cleaning the air vs ducts, A-coil etc. I also believe the cold air return side puts less heat stress on the bulbs during the winter months. I too have read that the bulbs have a shorter life when cycling on and off more often. Just leave them on is what I do.
What is a typical cost for a UV light in an HVAC system? I know it would vary by size of system, etc.
I was quoted 3K. I passed. Found the stuff on Amazon for less than $200.
U can get it for around 600 dollars but it’s the homes we live in so just sleep in your home at night and spend most of the time outside of it , I can smell the mold it’s smells like dirt or earthy smell
My Hvac guy wanted $1800 for this light. No thanks.
My HVAC system became contaminated when one of the returns was breached allowing contaminated air from a crawl space to enter. The ducts were cleaned which helped significantly but there is still trace amounts of the Oder coming through. It seems like the UV will not get the remainder of it based on this video. Any suggestions on how to sterilize the ducts?
I know this is a year late for you, but an air purifier like the IWAVE-R or the REME HALO will sanitize tour duct work and home 24/7 offering protection
During the pandemic a lot of public places like schools and shopping malls had those lamps installed in their air ducts for the purpose of reducing the spread of COVID! :)
Just don't buy a Reme Halo led. Mine actually grew mold on it.
UVC lights are actually installed in HVAC system, thru which both cold and hot air pass. It also need to be calculated in right frequency and wattage for that particular area.
I have to tell people all the time that UV lights don’t destroy airborne mold contaminants.
I wave r and uv light together are a pretty sound for airborne contamination uv to.keep the coil clean
I install ionizer with UV and upgrade the filters and yes it kills the mold
Cool vid. I figure it wouldnt work to clean air
What about Ozone coming from these lights?
They aren't strong enough to produce ozone
They do have UV lamp with or without ozone
My remove all odor
Thats what we want tho lol
Yes but not in the rest of the house. NO SH!T
JUST KEEP RUNNING THE PIE HOLE NEVER GET TO THE POINT
It doesn’t just keep your ac system from getting moldy. It kills the mold that’s in the air traveling through your ac system. This guy talks as if it only purifies the ac unit itself.
It will only kill mold on the surface of what the light hits, this because of the length of time it is exposed to the UV. It will not kill airborne mold. It takes a lot of UV exposure to kill mold and the split second that air passes by is not enough. Read up on it.
@@Val-xi4we: Hey Val, are these things worthless, or do they off any kind of benefit in sterilization. I’m thinking it would be a waste of $500 to have one installed in a 3 ton unit for 3000 sq. Ft.
@@mannyandlorenaalmendariz9637 What Val said it true. The air is moving too fast, so the expose time is too short to kill the mold or virus. If your condensate pan is not pitch correct mold may grow in your AC system.

Why is there a sight-glass that allows you to see if the UV bulb is on, when seeing UV radiation is harmful?
The kicker:
The sight glass is right on the warning label.
Yes, it shows a person wearing sunglasses, but by the time you've realized that you should be wearing sunglasses, you're already been exposed.
If these systems are installed in utility closets, typically there aren't locks on the doors of the utility closet where the sight-glass, uv bulb & indoor unit is behind.
What's stopping a child from accidently exposing their self to harmful UV Light?
The sight-glass is stupid.
Why not just have a power indicator light mounted externally, so that you can verify that the UV Lamp is on & working...rather than a sight-glass that exposes you to the harmful UV radiation?
-Even IF you wear glasses, the rest of your face is exposed!
So maybe in addition to the stupid sight-glass on the worthless, yellow warning label with the guy wearing sunglasses....maybe they should draw a pic of someone putting sunscreen on their face?!
"DON'T LOOK AT THE BLUE LIGHT, KIDS!"
(right next to a sight-glass that let's you look at the blue light)
-Appearantly, the UV Lamp doesn't kill stupid!!!
