My contactor shorted out because of a bug. While the tech we here I got a look at the inside of my air handler and was stunned at the amount of mold I saw in there. He suggested a UV light but the cost put it out of my reach. I thought it cant be that hard so I went on youtube and found your video. Took a while to find one of the same quality but I just installed the Fresh Aire Blue Tube UV Light and your video made it a snap! My local tech wanted to charge me 800 to do the same job that doing it myself was about 215. My tech inspected the work and said its very good work and an excellent job. I also installed a REKO Lighting R2000 Air Purifier in my duct work. Thats a unit anyone can install and I now have double the security in my HVAC system. Thank you so much for your video. Im subscribed and following you from here on.

I hope you find this video helpful...thanks for watching from Jones Air Conditioning & Electric in Naples, FL!

Thank you David, I installed 2 UV lights and cause of you we saved $800. parts costs me $200. from Amazon Thank you again,

Awesome video Mr. Jones.. love the way you break stuff down and get straight to the point !!

I really appreciate your detailed video on UV light purification... it has helped me with my decision on adding this to my HVAC system. Your company seem like a team of honest technicians who do excellent work just wished you were in the New Jersey area

Great instructor and instructions...right to the point and easy to follow step-by-step instructions... Thanks

Mr Jones, Great job on the video. Very thorough with out a lot of unnecessary footage. Thank you!

My UV light manufacturer states any wire coming from the UV light, that will be exposed to the UV light, should be wrapped with foil tape. So the wire that was behind the metal panel on the coils should be wrapped with foil tape.

Wrong side of the breaker Mr.Master A/C Tech

Nice job!!!

Love the video, thanks. Would love if you would include links to the light, mount, sight glass, and bit.

am curious as to why the uv light needs to be on 24/7. Wouldn't it be better to come on when the fan comes on and go off when the fan goes off.

This breaker was already in the air handler. If there isn't a breaker wire the high voltage under the main lug in the heat strip. Hope this helps..

David Jones you ROCK!

When you wired the transformer to the breakers you hooked each wire to 110 hot leg?

good vid. From what I been reading you put it in wrong place due to the light will brake down the air filter. light should always be past coil

I have a question, I see every one connecting their UV system to a straight power source. My question is, why can't you connect your transformer to a relay system whereas it will only activate when the system is active by tapping a trigger off the control of the thermostat. Finally, what would be a good wattage for an effective UV system.

A little light will not hurt you, do not stare at it . It could burn your eyes. Be careful . Thanks for asking.

again my name is Diego I like it better with the dedicated transformer due to the fact that uv light recommendations are to keep it 24/7 on I was told to use a relay g&c to the load an R&C to the normally open side of the relay in series with the light bat like you say in the video if UV light amp dropped down thermostat require amp we looking for nothing but trouble I would love to have an answer about correct blade fuse site to protect the dedicated transformer in both sides 240 & 24 V thank you very much

follow you steps and installed one but getting a burning smell. When I disconnect the light the smells goes away. Since I only disconnect the light that means is not the transformer or any of the connections.. What can it be?

I had a friend give me a brand new one. It’s got a low volt transformer 24 V doesn’t have the 240 and the 24 and you’re exactly right when you hook them up and they’re not hooked up right what it was doing was the compressor come on the outside fan would run but only for about a minute and then shut off the inside unit unit was running so my question is you have a red and black wire coming out of the ballast? What do you hook those up to any help I would appreciate thank you.

If bulbs were handled with fingers, can they be wiped down with alcohol before installation?

I hope that wire for the power supply is UV proof, it is been exposed to the light and if its not UV proof it will crack it possibly short circuit the line.

Can you get a 120v power source to turn on only when the blower is on?

Helpful video. Except for your double tapping of the breaker to feed the transformer. Code violation.

For maximum strength should be replaced every year, if it is still working change it out in two years.

Great video.

Thank you!

Very good videos thanks

You said it was a 9000 hr bulb then you said it was good for 2 years. Wouldn’t that be 18,000 hours for 2 years... The transformer normally goes to black and orange for 220V. Not white “Common”... There’s a cretic in every crowd! Good job on the video! Thanks for sharing.

Thank you, I appreciate that... I hope it helps..

Great Video well explained, Thank you for your time

You could probably use a few strands of fiber optic cables.

Where did you get the sight glass from. Thanks for sharing

Why couldn't you mount uv light with simple ext cord?

Very informative video. Thanks.

Thank you good video

Mr. Jones, have you ever experienced a weird smell coming from the light after installation? we had one installed and keep having a weird smell coming from the area. not sure if it’s potentially killing bacteria in the coils? Any insight would be appreciated. Thank you Great video

@Tony Lampson : UV lights are good for 1 year / it looses its ability sterlize even though the light is still blue.mtrust the manufacturer recommendations - they made the system, literally.

So Mr. Jones, the best place to mount the UV light is just before the Evap coil, on the return air side? The reason why I ask is because out in the field I have come acrossed this 24 volt UV lamp & have always seen it mounted in the supply plenum. I am not questioning your expertise. What you've said makes sense. Just wondering why so many of these UV lamps were installed in the supply plenums on both verticle upflow air handlers, & horizontal air handlers. Any thoughts on this? Thanks for your awesome video!!!

Thanks hope it helps.

Is it okay to place the uv light above the slanted coil instead of under? Is under more effective? Its difficult to install my lights under

also, i forgot to add that im using exactly the same UV light you are using... thanks

Hi my name is Diego I recently graduated from HVAC technician school I have a concern about the new dedicated transformer for the UV light regardless fuse sides protection for the 240 V and 24 V due to the fact then we have extremely oversight breaker when the system is not running so we should put blade fuse on the 240 V side and another blade fuse in the 24 volts side and how we get the fuse amps correctly

I am glad it helped.

Do NOT look at the light! There should be warning stickers that are added to the exterior of the unit. It is no fun dealing with someone that can not see for a few days!

DO NOT LOOK AT IT DIRECTLY! It can cause temporary to permanent eye damage if expose to it. I installed one and looked at for for a little and I got a “sunburn” to my eye and it’s the worst feeling. Be careful and make sure to use the little glass that comes with it. Also turn it on once everything (machine) is covered up/close.

Did you double tap? That's kind of a no no.

Check the transformer on the uv light, it should have a separate transformer . Hope that helps.

hi i find my answer.. from the transformer to the black box.. of uv cord... really confused me black to red and red to green.... if you do it the other way it will not work or turn on... DAVID.. please let us know how the wires go . so we do not get our self killed. 120 or 240. thank you... this was for me. 120 vac/24v uv light.

thank you for the video

Where would the transformer be? How do I get to it? This UV light system is a free standing Honeywell unit. It has the "box" that you bolt to the a/c unit...This "box" is what you insert the uv bulbs and the bulb holder into. When I insert the bulb into the holder ( it is a 4 pin light ), turn the holder 1/8 turn to the right, the blue light does not come on. My power supplies are working.

Is it ok to run the bulb to run with the furnace? furnace on bulb goes on, furnace off bulb goes off. I understand the bulb wont be killing as much as possible but to be on 24/7 seems to be over kill for me.

So adding this to any large hvac system I just mount it against the sheet metal

What’s the different using a 208/230v light versus a 115v light?

Sight glass good idea

Great video

Great video. Will installing the UV light on the bottom as you did inhibit mold and growth on the other side of the coil or should the other side of the coil have UV lights on it as well? Mine has mold on both sides of the coil.

Good video. Thank you.

I screwed up i thought the power unit was a transformer and i hooked it up to my 120 volt 🙄 it turned on and off did i burned the ballast?

I had a ac company install a uv but they did not use any transformer. He wired it directly so it is on only when the unit runs. Is that a correct way to install a uv? Thanks for your help.

Came across one of these where the blue light wont come on with any bulb. When you twist in the green light lights up but the bulb wont light. Any ideas as to why and what i can do to fix it?

Will the AC plug in kit work as well as the hard wired install? I have AC outlet up in my attic. thanks

David Jones how to buy Uv light

Hi mr mike I did the same steps that you show in this video and I also replace both UV bulbs I still don't get them to work any sugestión ?

Correct.

Is it alright if my AC technician just drilled a hole in the panel to see the UV light and did not put sight glass?

hi there i have a question. from the black ox to the transformer. for 120 volt.. there's 2 colors of wires on each . which is which.. trying to do this right..

Great video. Question. What if the A coils are mounted sideways and I place a uv light right in the middle. Is it likely to get ‘rained’ on.

would i be okay if i put some up in my room

my hvac system has the honeywell uv light...it is a 2 pronged light...question....one of the you tube videos says when the uv light is working properly, the blue light on the twist on handle will be lit. my blue light is not working; however, the uv bulb appears good. i'd say the bulb is about a year old. what could be the problem with the blue indicator light not working???

Why not mount on both sides of the coil?

Let’s just not mention that you need to install the uv with very clean coil.....

Use microfiber cloth.. Try to avoid touching.

Doesnt kill whats in the passing air. Kills anything on the surfaces of the coil or what ever surface the light hits

Yes

Nice video. Except for the wiring. Mine was installed to turn only when my Heater, Ac or Fan is running. I would not install this to be on 24 hours a day or you could burn though lights in a couple months as opposed to 6-12 months.

Can more than one UV light be connected to the same transformer? or can more than one transformer be connected to the 240v.?

I have a 3-ton Goodman AC unit what Step Down Transformer should I use?

what is the model number of the light stick as seen on the first part of the video? thanks

Hello David, the light is good for 9000 hours. This means it has to be replaced after one year (375 days) and not two years as mentioned at the end of the video, right?

Hello everyone ,where can find the side glass for the uv light

Light stick, or Bio fighter. Any standard 240-24 volt transformer

Is this really needed

I wish to know is it okay or safe to replace a 12 watt 10 inch uv light with a 17 watt 14 inch uv light bulb?

9000 hours is basically 1 year and 1 week

Wht abt thd ozone generated

If you put the light inside the coils doesn't it make it susceptible to condensation?

Nice, but UV light should only need to be on when the fan is also on pulling air through the coils and ductwork. If your UV light isn't on 24/7 it will save money on electricity and bulbs will last much longer! I have 3 UV lights in my pool plumbing and use no chlorine anymore, but they only turn on when the pump turns on 8 hours in the winter, 12 hours a day spring and fall, and 16 hours a day in the summer in Miami, Fl.

What do you think Air Scrubber Plus by ActiTek with Space certified ?

Do you have hvac electrical classroom training ?

hi thanks for the video! one question though, do i always need the first box (transformer) to have or install? or most AC units should have it already? im installing the UV light on my condo tha has an AC unit with a cooling tower that goes all away until the 22nd fllor. I live on the 9th floor... thanks so much in advance!

Hi, I have looked up and down and can not locate where to purchase the sight glass for the ac cover panel, can you advise me please. Thank you

Tell them to make sure they stripped all the wires on everything they’re doing don’t use the factory connectors

Hi David, what model of Square D circuit breaker are you using? 40 amp? 2 Pole? And what kind of mounting bracket are you using? I want to make sure I'm doing the exact same set up you are in your video-which is AWESOME!

Does UV light penetrate copper pipes?

I had a Uv Light put in a few days ago. My Air handler is in doors when it got night time I noticed that the UV light shines throung the house form the Ac fliter is this safe to our eyes?

Do you have hvac electrical classes ?

I see that on the slant coil you mounted it underneath the coil. all other places show to mount over coil. does it make that much of a difference?

where do you get a site glass?
