As with all UVC light, it is to kill viruses, molds, and less so, bacteria and spores when exposed to the UVC for a period of time. Essentially destroying the DNA and RNA of microorganisms. That's why the unit being installed here, as with all other UVC lights, are recommended to be installed at the coil assembly where you get the moisture condensation from the coil, and the debris blowing over it, causing such issues. The UVC lights are designed to be left on in coil area to act on them. The coils in there, as well as the surrounding duct is all metal. UV light does not affect metal. However, this video shows placing the UVC light in the return duct. Air passes through there at a high rate, meaning there's not enough time to expose virus and molds to the UVC light to have much of an impact. You would need a much more intense UVC source so that length of UV exposure needed to kill viruses, etc, is reduced. Meanwhile, installation in the return duct shown here doesn't do anything about the issues in the coil area, where this was meant to be installed in the first place. Also be aware if you replace the bulbs, make sure they are coated to prevent production of ozone, not good for your health. Ozone is generated by the breakdown of oxygen at the 185nm wavelength that can be generated by some of these UVC bulbs. The bulbs used in this Reko unit are Ok, but caution on getting replacements that are not certified regarding ozone.

100% agree - all the nasty stuff accumulates below the coils at the draining pan and that's where the UV lights would do the job. I personally places one unit above the coils and another after the coils before the blower that is also facing the drain pan

Thanks for sharing. Excellent work! The UV glasses is the less obvious but definitely a good call.

Good job…👍 Thanks 🙏

Good job…!!👍 Thanks 🙏

If you are not concerned about the little if any mold on the coils (IMO, if you have mold on your coils, you should be finding the root cause instead of damage control). I want to kill bacteria, viruses, zap dander before it hits my filter element. I've heard you can install these AFTER the furnace or before the filter. With that said. Great video and your little helper is a natural. Good work.

I had planned on using this type of light in another application and I have UV protection eyewar for myself but adding the UV window port was pretty ingenious, thanks for the tip.

Location, location, location. Yes, some germs might be killed passing by it in the duct. To effectively kill the most germs the light needs to be placed either above or below the A/C coil in the main trunk, out of the way of dripping condensate, depending on the shape of the coil(s). That's the place where germs have the best place to grow in the cool damp environment of the HVAC system.

@@gial8862 The air from the blower blows through the coils to send cool air through the vents to your house. Condensation will form from the warmer air and drip down. So the UV light, as others have mentioned, should be above that. It will shine on the coil, and the drip area. Some furnace units recommend UV on each side above the A coils to ensure the UV is able to get to all affected areas.

My HVAC was installed in 2016. I think placement depends on what worries you most. Bad mold is not in the HVAC itself but in the walls. What most people are troubled with is whats being SUCKED into the system or BLOWN throughout the house. When my HVAC people were asked, they said best placement is in the main duct work feed. Any "bugs" that makes it past the filter (mine are 4inch wide merv 13). This would sterilize bacteria, viruses , etc. Or right before the bend in the return to the filter which would kill the nasty stuff before they got sucked into the filter. They, like this man, stated that the UV-C light over time can harm the some of the hardware but takes time. So, depending on who you ask, you get 3 different answers. Bottom line, what ware you trying to clean will help you decide where it needs to go. For me, it has to be just above my Humidifier which is in the return vent, 4 feet above the filter/fan. I've yet to see anyone address how this will shorten the life of your bulb if it's in an areas where it's getting hit with moist air all the time.

Always on the supply side past the filter in your case in between the a coil because you don't really have a supply plenum. that thing is going to prematurely fail due to the dust from the return

Hello everyone Thank You So Much for all the support (BTW I’m the girl in this vid) but Thank you all for the subs, the views, likes, and all the comments! :)

Put it in the evaporator coil, and patch those two holes up. You are just wasting electricity with that in the duct.

I have an outside heat pump for cooling and heating. There is inside unit and both the return and supply are in the crawlspace and are SOFT duct. Can you install one of these units in outside heatpump? If so how is it protected from exposure to weather, rain, etc.

@@diyspecialists710 there is one thing to note. if this is installed in the supply side of the duct and the light hits flex ducting the uv light will degrade those ducts in about 2 years. To prevent that the flex duct needs to be lined with something that is UVC light proof or sections of the flex duct needs to be replaced with UVC proof flex duct. This applies only what is in direct contact with the UV light. Also if there are any wiring that is exposed inside the furnace or air handler to the UV light the cabling needs to be wrapped as UV light will break down the insulation of the wiring. This is especially true if installing in the return side of a furnace or air handler. If the UV light is installed where the light can hit the air filter the UV light will break down the paper media in the filter causing holes to form in the filter so be sure to install it away from contact of the air filter. the best location if practical and possible is in the supply side duct right in front of the coil. as your video states the light will kill bacteria, viruses and molds which is always good for health reduce odors etc. But also inhibiting mold growth on the coils keeps the air flow at max efficiency as the mold growth inhibits airflow through the evaporator coil. If it's impractical to install the UV light in the supply side near the coild you can purchase a stand alone coil UV light that can be installed in the coil and work in tandem with the main UV light.

I think we should create a device like this cars and mail trucks so that way if the mail carrier who is driving the vehicle is not being contaminated and they are not contaminating anything in the vehicle like packages and mail and other items,infact I also think they should just have some way to sanitize any mail or packages that come into the building,because mail carrier's have a very big potential to spread the virus even if It's by accident.

@@diyspecialists710 The condensing coil is on the outside unit (with compressor). The inside coil is the evaporator coil. For a UV that is on 24x7 better place is below the A coil or evaporator coil.

Not quite sure I understand how to answer your question, but maybe I can get it right. First off, there is no blower connected to the unit itself. The blower in the air handler is what moves the air past the UV light. The unit gets plugged into a typical 120 volt receptacle and does not seem to use much electricity. The product rating does not really cover something like that, because UV light does not kill viruses, bacteria and molds at the same rate. My research has it that some viruses are more hardy and require more UV light to die. That is why I have really thought about installing more UV lights throughout the duct.

Thanks for the comment. The unit is somewhat close to the filter as it receives indirect UV light, but I am not concerned with UV light hurting the filter. The filter gets changed out regularly and before it gets degraded enough to matter. That was part of the reason for putting the unit at that location. I have seen these units placed in the box shining directly on the filter and I think that is okay because like before, the filter had a high MERV rating and thick enough so that the UV light did not shine through the filter and that they get changed out frequently enough.

It actually burns the fiberglass faster LOL
