In 1903, Niels Finsen won the Nobel Prize in Medicine for his use of ultraviolet light in the treatment of tuberculosis. Since then, ultraviolet lights have been widely adapted for all kinds of uses: sterilizing hospitals, sterilizing water, germicidal lamps in food establishments, and even curing nail polish faster. If UV light is so effective, how can it be applied to improving indoor air quality for residential HVAC systems? Will it kill mold and bacteria in HVAC systems? Yes, but you need to understand the priorities of indoor air quality and the types of UV lights available for residential HVAC systems. About 2 years ago, we installed a 19 SEER Lennox XC 21 air conditioner. During our most recent AC service, the technician also installed a TopTech HVAC UV light inside the air handler, which remains turned on 24/7. According to the technician from Engineered Air, HVAC UV lights are very effective at controlling mold inside the air handler. All mold in line-of-sight of the UV bulb will be killed, keeping the coil mold-free.

He also mentioned that several clients with respiratory problems are even able to tell if the UV bulb has burned-out due to reduced air quality. I’ll let you know if I am able to tell. There are two types of UV lights for HAVC systems. Two studies point to the effectiveness of UV light in killing mold and bacteria, one in hospitals and the other in a commercial HVAC system.10000 btu window air conditioner for sale The TopTech UV stick light bulb is estimated to last 9000 hours, just over 1 year. cumberland air conditioning unitsReplacement bulbs cost about $70. 93 honda civic ac wiring diagramReplace the bulb during each annual HVAC service and maintenance is nearly effortless. The TopTech UV light we installed is rated at 1.1 amps.

To calculate annual energy costs, I used these handy calculators For just under $100 per year ($24 electricity + $70 replacement bulb), my family has peace-of-mind knowing that we are breathing the highest-quality indoor air. It seems like a small price to pay. But it doesn’t make sense to install an HVAC UV light unless you’ve followed the indoor air quality priorities. While HVAC UV lights are effective for killing mold, bacteria, germs and odors, make sure you have completed the indoor air quality basics: HVAC UV lights are an effective means for improving indoor air quality, but only after following the indoor air quality priorities. Install an HVAC UV light and experience healthier indoor air quality. in your air conditioner system. The UVC purification lights must be mounted next to the evaporator (cooling) coil, AND on the downstream (cold air side) of the coil. must shine both on the air conditioner cooling coil and on the water drain pan underneath

the coil (if installed), because this is the main area where mold spores grow. The Air Probe Sanitizer in the photo above isindeed mounted in a duct, but it is illuminatingthe cold side of the A-coil and water drain panunderneath it.(Click the photo for a different view). If the UV-C lamps are mounted elsewhere, then slime, algae, bacteria, and mold WILL grow on the cooling coil, drain pan, and even the blower and ductwork. As a consequence, these organisms will contaminate the air that you're breathing, throughout your living Furthermore, this slime, algae, mold, and bacterial growth can eventually plug up your air conditioning coil so air can't flow through it freely. increases cooling costs and can even shorten the life of your central air conditioner. AC coil will NEVER plug up with a properly installed and maintained Air Probe Sanitizer equippedThe cooling coil will always look as shiny and new as it did when it came out of the factory.

The UV-C rays shining on the water droplets (the water condensing on the A-coil) increases the output of helpful hydroxyl ions (OH-, a naturally-occurring air purifying compound that scrubs pollution from the earth's atmosphere) and other compounds that destroy organic material such as mold, dust, germs, An ordinary "in-duct" system can do neither. The Ultraviolet Lamp UV-C output power rays from the uv lamps must be powerful enough to eliminate odors and freshen the air, as well as kill germs, viruses, bacteria, mold, and mildew. Probe Sanitizer™ to others. The UV-C wavelength specification All ultraviolet-C "light" is"UV-C" takes in a very broad spectrum ofAnd most wavelengths in the ultraviolet-c spectrum do nothing to either purify the air or kill germs. Only an extremely narrow band in the UV-C spectrum is actually useful to purify the air and killThe Air Probe Sanitizer's lamps are unequalled. Click here to see for yourself that all UV-C lamps are not created equal.

It should not produce ANY ozone While ozone in some air purification applications is not always a bad thing, you do not want ozone-producing UV in your ducts because: Ozone from a UV light cannot be adjusted or turned on and off. pollution and odors are destroyed, you will smell ozone. Ozone in the presence of germicidal UV-C rays would corrode your air conditioner's cooling system, and even separate the aluminum fins from the copper lines in the air conditioner cooling coil. Much of the ozone is destroyed by the UV-C rays anyway. Besides, you don't need ozone to purify the air! UV-C, the purifying hydroxyls and negative ions can do the job. Hydroxyls and negative ions...Must be produced by the UV-C air purification system and must come out vents and registers. This is very important to purify the air and help keep dust, allergens, and pathogens (disease-causing organisms) out of the air. ions are the key to actually

destroying dust, pollen, mold spores, VOC's, drug- and antibiotic-resistant pathogens, and other organic compounds in It must keep the air ducts and AC cooling coil clean.The Air Probe Sanitizer does just that. (Please see #1 above.). The duct-cleaning people hate these Ease and cost of installation of the UV-C air purifier is difficult, then installation will be expensive (or just not done correctly). Probe Sanitizer's different designs accommodate any air handler design you might run into. There are a number of clear advantages in this regards of the Air Probe Sanitizer. For one thing, there are many, many different makes, models, sizes, and designs of air handlers (HVAC systems), and as a consequence, we often we have to make a custom-length Air Probe Sanitizer (or a special lamp spacing) to fit a particular air handler. And not only is there usually no extra charge should a custom length, lamp spacing, or mounting configuration is required, but many custom

Air Probe Sanitizer lengths and different designs are stocked.Inferior, similar-looking "in-duct" UV-C air purifying products have another major drawback: fixed sizes and designs with little flexibility. The main problem is that other dual-lamp model (which are required on almost all residences without exception) have a fixed lamp spacing. They just plain won't properly fit some air handlers, no matter what. And so they just don't do the job of purifying the air and killing mold. And the only way you can make their unit work on some air handlers is to chop some holes in the sheet metal. Some homeowners don't like that, because it voids the warranty on their Furthermore, on top of the fixed-lamp-spacing limitation, there's also only one mounting design, either for single-lamp or dual-lamp models. You just don't stick one in a duct somewhere, or blindly mount it "on top" ofIf the lamps aren't mounted on the COLD AIR SIDE of the evaporator coil, and

close to the coil so as to fully illuminate it, then the job is not done right. the different Air Probe Sanitizer designs and lamp spacings ensures a job done right, and a happy The bottom line here is this: Flexible installation translates to quick installation, which in turn means the lowest possible installation costs. Lamps supported at one end only This not only makes for easy installation and replacement, but doubles the effective length (and UV output) of the air purifying UV lamps. Long lamp life - Up to three yearsMany ultraviolet germicidal/air purification lamps quickly drop in output power, loosing their effectiveness at purifying the air. These lamps' all-important UV-C output decreases less than 15% after a year (8760 hours) of continuous operation. On the average, these ultraviolet lamps can still emit 85% after 1 year, 73% after two years, and over 60% after three years. Number of UV lamps (two lamps in one)

UV air purifier system effectively give you four lamps, since each lamp is really two lamps in one, side by side (supported atYou have to have enough lamps to provide enough UV-C light energy to purify the air and kill mold, etc. Easy UV Lamp Replacement No UV lamp lasts forever. When it wears out, it needs to be easy to change. The lamps on the Air Probe Sanitizer just rock out of the sockets. see the video to see how easy it is. ultraviolet-C lamps and the aluminum frame of the Air Probe Sanitizer air purification system are rigid and solid. The lamps are as highly resistant to Dual-probe units purify and clean the air in even large houses. Multiple probe units can be built for any application, whether a home or a skyscraper.The smaller one-probe "motel room" units can even purify the air in a small townhouse apartment. Customizable at no extra cost Need a special length? Usually, there's no extra charge. The cost is based on the number of lamps,
