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. air temp ac unit reviewsI’ll let you know if I am able to tell.portable ac units for autos There are two types of UV lights for HAVC systems.samsung window air conditioner prices in india 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. The TopTech UV stick light bulb is estimated to last 9000 hours, just over 1 year. Replacement bulbs cost about $70. Replace 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.Q: Do you remove or replace condensate pans, cooling coils, supply fans, or other AHU components, and is there any demolition or construction involved?We do not remove or replace any components inside the air handler, and no demolition or construction is involved.

The installation simplicity of our solution is the beauty of it. Nothing is removed, and repairs to condensate pans and floors are made in-place, allowing for minimal operational downtime of the unit. Q: Are odors an issue with the AQUIS System?The AQUIS System contains zero VOCs and no detectable odors both during and after installation. During the installation process the air handler is isolated by sealing off adjacent duct work, and through the use of negative air machines equipped with HEPA and charcoal filtration. We have worked inside air handlers serving some of the most critical environments imaginable (hospital ICUs, operating rooms, biotech and pharmaceutical laboratories, etc.), and we are frequently told that nobody had any idea we were there. Q: What’s the downtime with installation? A: The AQUIS System is installed in two 8-hour work sessions, typically after-hours and into the middle of the night when general occupancy and facility HVAC requirements are in less demand.

Immediately following each 8-hour session, normal AHU operation can resume. We are happy to help accommodate you with any special scheduling requirements you may have. Q: How much does it cost? A: Due to the many variations and sizes of commercial air handling units, we would first need to visit your facility to take measurements and assess the overall condition of the units. We are well-versed in scaling projects to work with both active FY maintenance budgets and capital planning budgets, and we will work with you to fit your needs and overall objectives. We also offer volume discounts. Generally speaking, the cost of refurbishing your air handling units factors out to be approximately 5 - 10% of the total costs to replace them. The savings achieved can then be put towards other pressing facilities’ needs. Q: What’s the life expectancy after installation? A: The AQUIS System extends the life of your air handling units by an additional 10+ years by way of our extended warranty.

Considering the average life expectancy of most air handlers is 20-30 years, this increases the life expectancy by at least 33%, and even up to 50%. Q: Do you refurbish outdoor plenums? A: Yes, weather permitting. Q: Do you coat cooling towers? A: No, not at this time, but we are currently working on solutions for cooling towers. Q: What sets you apart from the competition? A: Air handler refurbishment is a very niche HVAC systems specialty, and AQUIS is the only solution available that’s fully compliant with fire codes, NFPA, ASHRAE, Joint Commission, EPA and others. Fire code compliance is essential when using supplemental materials inside an air handler, so we urge you to do your homework ask questions. Not only is AQUIS compliant with NFPA 90A – but we can prove it. With over 12 years of experience working in virtually every industry and commercial environment, our expert installation teams have seen just about everything that can go wrong inside an air handler.
