The tropical climate in Florida allows a constant flow of humid and moist air through your ducts, contributing to that pungent odor in your home.
At GreenFox, we specialize in high-performance air purification systems that dramatically improve indoor air quality. Our filtration services are designed to reduce allergens, eliminate airborne pathogens, targeting what you can’t see, but definitely feel.
Palm Beach County offers sunshine and ocean breezes — but our hot, humid, and pollen-rich environment also creates ideal conditions for poor indoor air quality.
What You’re Up Against in South Florida:
High Humidity: Levels often exceed 70%, fueling mold growth, dust mites, and moisture damage in insulation and ductwork.
Pollen & Allergens: Our subtropical climate means long allergy seasons and high airborne pollen from grasses, trees, and plants.
Dust & Contaminants: Outdoor dust, mold spores, and bacteria easily make their way inside and circulate through HVAC systems year-round.
It’s a fair question — and one we hear often.
The short answer: UV lights aren’t a scam, but they’re often misunderstood.
Most HVAC contractors focus on mechanical systems, not indoor air quality. So when mold shows up, they’re trained to say, “UV lights kill mold.” That’s true — but only part of the story.
UV lights are preventative, not corrective.
If mold is already present in your HVAC system, a UV light won’t remove it. The contamination will remain unless it’s professionally cleaned.
However, once the system is clean, UV lights are highly effective at preventing future mold and microbial growth — especially on coils in South Florida’s humid climate. They help keep your system cleaner, healthier, and running longer.
HEPA filtration is one of the most effective air cleaning technologies available — the same standard used in hospitals to create sterile environments. These systems remove 99.97% of airborne particles down to 0.3 microns, including dust, pollen, pet dander, mold spores, smoke, and even some bacteria and viruses.
Installed inline with your HVAC system, they provide whole-home purification — not just in one room. While UV lights neutralize biological contaminants, HEPA filters physically remove them from circulation. Used together, they create a powerful, comprehensive solution for cleaner, healthier air throughout your home.
We'll help you identify the ideal whole-home air purifier to meet your needs and discuss solutions tailored to your home or business. Schedule your appointment today and breathe easier with our professional air purification solutions.
While UV lights themselves aren’t complex, installation involves working with your electrical system and accessing the interior of your HVAC unit. For safety and correct usage, it’s highly recommended to have a qualified HVAC technician install your UV lights. They’ll ensure proper installation, secure electrical connections, and verify compatibility with your specific HVAC system.
UV lights emit ultraviolet radiation that can target and kill or inactivate airborne viruses, bacteria, and mold spores as they move through the HVAC system. This can potentially improve indoor air quality, especially for those with allergies, respiratory sensitivities, or concerns about airborne contaminants.
For maximum effectiveness, UV lights need strategic placement inside your HVAC system. The location typically depends on the unit’s layout, but generally:
Downstream of the air handler and coils: This ensures the UV light treats contaminants after they’ve been filtered by the air filter but before circulating through your home.
As close to the evaporator coil as possible: This placement maximizes exposure of the light to contaminants on the coil itself where most contamination occurs.
For A-shaped coils, consider two UV lights: One on either side of the coil can provide better coverage.
UV lights provide potential benefits for air purification but are not a guarantee . It’s important to consider a few key factors. UV lights primarily target airborne microbes and may not address existing mold growth. If mold is suspected within your HVAC system, professional HVAC remediation is remediation.
