I have white mold I believe not sure growing by the system in my attic behind the blower where it drips and slide down to the drain pan. What the best way to wipe it or clean with what chemicals inside the HVAC system?
In my installation, I have a bypass humidifier installed on the return line about 5 1/2 ft above the floor tubing going to the plenum above a packaged A coil. The plenum above the packaged A coil is about 15” then goes into a flex connection for about 2” then another 15” plenum, then into the main trunk delivering heat or air depending on the weather/time of the year. Where would I install the UV light? Thanks….Jim PS……my Trane furnace electronic board has many places to trigger different things like a humidifier, electronic air cleaner (which I’ve always had & do now), etc. I would like to know why you’re not triggering the UV light to be on with only the furnace/air is on? Thanks again!
Anywhere in the Plenum is OK or even in the supply ideally you would like to have it shining down on your a coil if possible also you can wire it to only shine when the blower of your furnace or air handler comes on however you can leave it on continuously as well hope that helps
Great video. Can you help me of where is the best location of UV to install for purpose of sterilizing operating rooms in the hospital? Is it in return side or after the coil?
Always put it in the supply side above the coil. You can put it on the return however you would want the light shining on the coil at all times to prevent mold from building up on the coil. Hope this helps
At some point, you mentioned 24v, however, the installation shows the tech plugging into a standard outlet. At the beginning of the video, I thought he was going to show how he wired it to the main board of the unit so the light comes on when the furnace/ac is on but that wasn't the case. Appreciate the video and the location info. Just pointing out the voltage question.
Yes you can wire it to the air handler direct, however to get the most effective results it should shine continuous on the coil to kill any bacteria or viruses
You wouldn’t want to install it in the A coil. That’s very damp and if the condensation dripped down on the unit or worse if the bulb were to break or become dislodged the results could be catastrophic. 🔥🔥🔥
Very clear and well presented. Thanks. One question about drilling the hole - what do you use to drill the hole and how do you ensure that the round piece of metal that you cut out does not fall into the plenum and can't be retrieved?
I have a humidifier installed on the plenum above the coils. Can I put the light near the humidifier? Also, I have a vent higher up on the same plenum for the basement. Will light escaping from the vent be a problem?
Preferably you would like to have the UV light about 9-12” above the coil. If you dont have room you can put it above the humidifier no problem, it will still purify the air but may not shine down on the coil as much. Also the light has a reflection sheild so if its shining downbit wont leak out of the vent.
@@jasongiannone1229 Thanks for the response! I have the room to install it. It could go behind the humidifier entering the plenum from the side, but I've read that the UV light can do damage to the humidifier over time. I checked Aprilaire's website and it even says the plastic housing is UV resistant, but not UV proof. I'm honestly wondering if it's worth installing a UV light at this point. While eliminating mold, mites, et cetera would be great, I don't know if I want to risk damage to my humidifier.
@@scott_litch it os recommended to install above the coil, however some contractors install these in the return as well- the goal is to get the air in your home passing through the light to eliminate particulates, either way should still clean the air, return installs just wont shine on the coil
@@scott_litch There are other products out there, where you can put a TUV BTER2 system on the return side of the coils. Video's available on the interweb.
The unit I have is 24 volt but is linked to the furnace 24 volt furnace circuit board such that it only comes on when the fan operates... otherwise, it seems to me that what you've installed is running 24/7/365 (which strikes me as unnecessary). Mine is on the return side... so it's not doing the coil-neutralization thing.
I want a uv light above my ACoil but I have already installed a whole house humidifier there . I have install a uv light in the return plenum as a compromise but really want the uv above the coil but think it will degrade the plastic frame of the humidifier. Please help.
Most UV lights have a reflective shield on them- as long as the UV has room to fit directly above the coil and underneath the humidifier- none of the light will go up( or very minimal).. Also the UV shining on the coil helps keep it clean from build up- however anywhere in the supply will help clean the air- especially if you have one in the return and one in the supply- you should be knocking out most VOC’s. Also you can consider an electronic filter- paired with UV, electronic filters can be an excellent way to make sure the air over running over the coil is free of dust, and many other pollutants. Hope that helps
@@jasongiannone1229 it doesn't clean the air , that's not even how uv light works. Uv light breaks apart the dna in biological life forms . It reduces odors/bacteria /viruses because they are primarily organic. The previous poster was mostly correct as the uv light does not have enough time to kill much accept for what's on the coil. These lights reduce the in air concentration of active bio matter by multi pass radiation exposure via air circulation . The air isn't cleaned at all in fact it contains the same amount of biological matter, how much of it that's alive / active is simply reduced as it's hit by uv light multiple times. Most of the uv lights sold simply do not have enough power to do very much to anything in moving air. If we use the systems in hospitals as an example a unit that size would have at least 6 times as many bulbs as what was placed in the video. They would be placed on all sides of the coil , by the blower and in the duct creating 3 stages to increase the exposure times and keep the most heavily contaminated parts of the system clean at all times.
@@MrBababuwi No it isn't and no he didn't . Cleaning the air would be a filter like a hepa filter since it captures the particles and biomatter. A uv light doesn't capture anything thing that's like asking if you fill a dirty sink with water did you clean it while all the dirt is still in the water. A strong enough uv light kills living organisms like live viruses making it damn useful but saying it cleans is a stretch.
@@wind5250 Thank you for all the comments. The UC36D16 UVC Purifiers does treat the coil and the passing air. These units feature high UVC output lamp which radiate high amount of Germicidal UVC rays which radiate out and create inactivation zone. The UVC rays can inactivate some microorganisms in a second. Sometimes the air moves faster sometimes at low speed. Air Cleaners capture particulates and some microorganisms. That is why you need both - engineered Air cleaner and UV purifier.
No, it won't. Most lights wear out faster when switched on and off. If you notice on an incandescent bulb, it only burned out when it was switched on. It never burned out while current was traveling through it - only when it was off and the filament was hit with a sudden jolt of current. Same idea here.
How do you know if your UV light bulb is good? There are two warning lights at the power source of my Comfort UV Light. One is for the power and the other is for the bulb. If the bulb is removed the warning light for the bulb is off. I put the bulb back on and the warning light turns on. However, how can I see if the bulb is actually on if I cannot see through the outer shell of the fan coil unit?
Good question-usually there is a small opening or area of the Air Handler or coil cabinet that isn’t completely sealed where you can see the light shining. Other wise you can always drill a small hole with a drill bit to see if it’s on and cover it up with silver tape. Hope this helps
They produce the same amount of ozone as any household appliance like a toaster for example- however through the ionization process these units actually have a negative ozone footprint.
That’s insane! Waste of money…no would pay an additional $250 at time of install. My AC guy wanted $450 at time of installation, the light itself cost $100. Any basic electrical sense and you can do yourself. Not hard at all.
