New Construction Doesn’t Mean Clean Air
Broussard has grown significantly over the past decade, with new subdivisions stretching south along Highway 90 and developments expanding through the Ambassador Caffery corridor. Newer homes are well sealed and energy efficient, which is great for utility bills but creates an unintended consequence: indoor air pollutants have nowhere to go. Tight construction traps moisture, cooking fumes, cleaning chemical vapors, and biological contaminants inside the building envelope.
Your HVAC system circulates that same air over and over, and the evaporator coil at the heart of the system stays perpetually damp during Acadiana’s long cooling season. Mold, bacteria, and biofilm grow on the coil surface in this dark, wet environment, and every blower cycle pushes those organisms through your home’s ductwork.
Stopping Mold at the Coil with UV-C Light
UV germicidal coil lights address biological growth right at its source. Mounted inside the air handler, these lamps bathe the evaporator coil in UV-C radiation around the clock. UV-C light disrupts the DNA of mold spores, bacteria, and viruses, preventing them from reproducing or surviving on the coil surface.
The result is a coil that stays cleaner between maintenance visits, drains that clog less frequently, and air that doesn’t carry a musty undertone when the system runs. For homes in the Copper Meadows, Broussard Estates, and Sabal Palms neighborhoods where systems run eight months out of the year, this sustained coil cleanliness makes a measurable difference in both air quality and system efficiency.
UV Air Treatment: Protecting the Airstream
While coil lights focus on surface sterilization, UV air treatment lights activate when the blower runs and target organisms moving through the ductwork. These are particularly effective at reducing circulating viruses and bacteria. During flu season or when respiratory illness moves through a household, UV air treatment reduces the number of viable pathogens in the recirculated air.
Both types install inside the existing air handler. No new ductwork required, no visible equipment in your living spaces.
Active Air Purification for Broussard Homes
The step beyond UV lights is active, whole-home air purification. Products like the REME HALO use photocatalytic oxidation to generate hydrogen peroxide molecules that travel through the ductwork and into every room. These molecules actively break down bacteria, viruses, mold spores, volatile organic compounds, and odor-causing particles on contact.
This is a completely different approach than passive filtration. A filter waits for particles to get sucked back to the return vent. An active purifier sends cleaning agents out to where the contaminants are, neutralizing them on surfaces and in the air throughout the house.
Why South Louisiana Homes Face Higher Risk
The Gulf Coast climate creates a perfect storm for indoor air quality problems. High outdoor humidity means high indoor humidity, even with AC running. Long cooling seasons mean coils stay wet for months. And the warm temperatures accelerate biological growth rates compared to drier, cooler climates.
Consider this: a mold colony that might take months to establish in a dry climate can take hold on an evaporator coil in weeks during a Louisiana summer. The condensation is constant, the temperature is ideal for growth, and the darkness inside the air handler protects organisms from natural UV light that would slow them down outdoors.
Choosing the Right Combination
For most Broussard homes, we recommend starting with a UV coil light as the foundation. It addresses the most common source of biological contamination in the system. If family members deal with allergies, asthma, or chemical sensitivities, adding a whole-home air purifier provides the additional layer of active protection against gases, fine particles, and airborne pathogens that UV alone doesn’t fully cover.
These systems complement your existing air filter and ductwork, not replace them. Think of it as upgrading from a single lock on your front door to a full security system.
