UV Lights, Air Scrubber and Healthy Climate Systems in Medford, NY
Your HVAC system does more than heat and cool your home — it circulates every breath your family takes. When biological contaminants like mold, bacteria, and viruses enter your ductwork, standard filters cannot neutralize them. They pass through the media and keep cycling through your living spaces. On Long Island, where humidity runs high from late spring through fall and homes stay sealed tight during winter, these invisible threats thrive inside the dark, damp environment of your air handler and ductwork.
Central Air Systems installs UV germicidal light systems and the Healthy Climate by Lennox air purification line to eliminate biological contaminants at the source. As Long Island's first Lennox Premier Dealer with 37 years of hands-on experience, our NATE Certified technicians know where to position UV technology for maximum effectiveness — and how to integrate it with your existing heating and cooling equipment without disrupting airflow or system performance.
How UV Air Purification Works in Your Home
UV germicidal lights use ultraviolet-C radiation to destroy the DNA of microorganisms, rendering mold spores, bacteria, and viruses unable to reproduce. When installed inside your HVAC system, UV lights treat the air every time it circulates — quietly and continuously, without producing ozone or requiring chemical treatments. Here is how we approach each installation.
Our technician inspects your air handler, evaporator coil, and ductwork to identify where biological growth is most likely to occur. We look at coil condition, drain pan cleanliness, and existing filtration. We also discuss your household's specific health concerns — whether that is mold sensitivity, recurring illness, or general interest in cleaner air — so we can recommend the right UV solution for your situation.
Not all UV systems are built the same. Coil-sterilization lights mount near the evaporator coil and run continuously to prevent mold and biofilm growth on the coil surface. Air-sterilization lights treat the airstream as it passes through, targeting airborne pathogens during each cycle. The Healthy Climate by Lennox UV germicidal lights combine both approaches in a single system designed to integrate with Lennox equipment and compatible HVAC systems. We match the technology to your goals and your equipment.
Placement determines whether a UV light actually works or just glows inside your air handler. Our technicians position the lamp where it delivers maximum exposure to the coil surface and the moving airstream. We secure the housing, wire the unit to your system's electrical supply, and verify that the lamp intensity meets manufacturer specifications. Improper placement — too far from the coil, wrong angle, insufficient dwell time — wastes your investment, and we do not cut those corners.
After installation, we confirm the UV lamp is operating at the correct output and that your HVAC system is running normally. We check for any airflow changes, verify electrical connections, and make sure the lamp indicator is functioning so you can easily confirm the system is active. If you are combining UV with an existing air filtration system, we verify both components are working together without creating excessive static pressure.
UV lamps lose effectiveness over time as the bulb degrades, even though they continue to produce visible light. Most UV germicidal lamps need replacement every 12 to 24 months to maintain their pathogen-killing intensity. We document your installation date, explain the replacement timeline, and can include lamp checks as part of your maintenance plan so the system never runs below effective output without your knowledge.
A well-installed UV system works silently inside your HVAC equipment, reducing biological contamination every hour your system runs. Our job is to make sure it is positioned, powered, and maintained so that protection never lapses.

Cleaner Air Starts
Where You Cannot See
The contaminants that affect your family's health the most — mold, bacteria, viruses — are invisible. UV germicidal technology neutralizes them inside your HVAC system before they ever reach your living spaces. As a Lennox Premier Dealer with nearly four decades of air quality experience, Central Air Systems installs UV systems that actually perform because we know where and how to position them.
Our UV and Air Purification Brand Partners
We install UV germicidal and air purification systems from manufacturers we have worked with long enough to trust their engineering, warranty support, and real-world performance. Our dealer relationships give you access to professional-grade products that are not available through retail channels.
Lennox
As Long Island's first Lennox Premier Dealer, we are authorized to install the full Healthy Climate by Lennox product line, including their UV germicidal lamp systems. Healthy Climate UV lights are engineered to integrate with Lennox air handlers and furnaces, delivering targeted ultraviolet-C radiation to the evaporator coil and airstream. When paired with a Lennox PureAir system, you get a layered approach that combines UV germicidal treatment with advanced filtration and catalytic oxidation for comprehensive air purification.
Bosch
As a Bosch Platinum Pro dealer, we install and maintain Bosch HVAC systems that pair effectively with aftermarket UV germicidal technology. Bosch equipment is designed for efficient, quiet operation, and their air handler configurations accommodate UV lamp installation without the clearance or wiring complications that some systems present. When we add UV treatment to a Bosch system, we verify that lamp placement and system operation work together seamlessly.
Mitsubishi Electric
As a Mitsubishi Electric Diamond Dealer, we bring deep expertise in ductless and ducted systems that benefit from UV air treatment. Mitsubishi's advanced multi-stage filtration already captures a significant portion of airborne particles, and adding UV germicidal technology to the air handler addresses the biological contaminants that filtration alone cannot destroy. For homes using Mitsubishi mini-split or ducted systems, we recommend UV solutions that complement their built-in purification features.
Central Air Systems has earned the Lennox Centurion Award — recognizing us among the top dealers in North America — along with the Lennox Partner of the Year distinction. These awards reflect the quality of our installations and our commitment to customer satisfaction across every product line we carry.

UV System Maintenance Plans
A UV lamp that has lost its germicidal intensity looks exactly the same as one that is working — it still glows. That is why scheduled lamp replacement is critical to maintaining the protection your system was installed to provide. Our maintenance plans include UV lamp inspections as part of your regular tune-up visits, so we catch declining output before your family loses protection.
Regular maintenance also gives our technicians a chance to inspect the evaporator coil and drain pan for any biological growth that may indicate a lamp positioning issue or a bulb that needs early replacement. Keeping your UV system maintained protects both your air quality and your HVAC equipment's efficiency.
Central Air Systems is headquartered in Medford, NY, and our NATE Certified technicians install UV germicidal and Healthy Climate systems for homeowners throughout Suffolk County and the surrounding areas. Long Island's coastal humidity makes UV air treatment especially valuable here — mold and biological growth thrive in the damp conditions that are a fact of life near the water.
From the South Shore communities where salt air and humidity compound indoor air challenges to the North Shore neighborhoods where older homes have ductwork that has never been treated, we have installed UV systems in every type of Long Island home over the past 37 years.
Frequently Asked Questions
UV germicidal lights emit ultraviolet-C radiation that destroys the DNA of mold, bacteria, and viruses. When installed near the evaporator coil or in the airstream, they neutralize biological contaminants as air circulates through your system. The result is cleaner air and a cleaner coil, which also helps your system run more efficiently.
Healthy Climate is Lennox's professional-grade line of indoor air quality products, including UV germicidal lights designed to integrate with Lennox HVAC equipment. These systems target mold, bacteria, and airborne pathogens using ultraviolet-C technology. As Long Island's first Lennox Premier Dealer, Central Air Systems is authorized to install the full Healthy Climate product line.
Most UV germicidal lamps should be replaced every 12 to 24 months. The lamp continues to produce visible light after its germicidal effectiveness declines, so you cannot tell by looking at it. Our maintenance plans include lamp inspections to make sure your system is always operating at effective intensity.
Yes. UV germicidal lights can be installed in most existing forced-air HVAC systems regardless of brand. Our technicians assess your air handler configuration and recommend the best lamp type and placement for your specific equipment. The installation typically takes a few hours and does not require modifications to your ductwork.
The UV-C lamps we install are designed to operate at a wavelength that destroys biological contaminants without producing harmful ozone. Some older or lower-quality UV products can generate ozone as a byproduct, which is why we use professional-grade systems from manufacturers like Lennox that have been tested and certified for residential use.
UV lights are effective at reducing musty and biological odors caused by mold and mildew growth on the evaporator coil and in the drain pan. If your vents produce a damp or stale smell when the system runs, UV treatment often resolves it by eliminating the source. For chemical or cooking odors, combining UV with an air filtration system provides more comprehensive treatment.
Absolutely. UV germicidal lights and air filtration serve different purposes and work best together. Filters capture particles — dust, pollen, pet dander — while UV lights destroy biological contaminants that pass through filtration media. We often recommend a layered approach, especially for households with allergy or asthma concerns, to address both particle and pathogen contamination.
We provide free, no-obligation estimates for every UV installation. The cost depends on the type of system you choose, your existing HVAC configuration, and whether you are adding standalone UV or a full Healthy Climate system. We also offer 0% financing for 60 months through Service Finance to keep the investment manageable.
