HVAC System Cleaning & Fungicidal Coating in New Orleans

IAQ Services provides comprehensive HVAC system cleaning and fungicidal coating for residential and commercial properties throughout New Orleans and surrounding parishes. Our service covers both mechanical and non-mechanical components — delivering a thorough clean that protects your air quality, your equipment, and your health.

What's Included in HVAC System Cleaning

Unlike basic duct cleaning, a full HVAC system clean addresses every part of your ventilation system. Non-mechanical components include:

  • Ductwork, plenums, and transitions

  • Return air registers, grills, and diffusers

  • Drain lines and all internal ventilation surfaces

Mechanical components include the coil and blower assemblies — areas where dust, mold, and particulate buildup directly impair system performance and air quality.

Foster 40/20 Fungicidal Coating

Following the cleaning, IAQ Services applies Foster 40/20 — an EPA-registered fungicidal coating — to interior HVAC surfaces. Foster 40/20 is specifically formulated to inhibit the growth of mold and odor-causing bacteria on system surfaces, providing lasting protection between service intervals. In a climate like New Orleans, where heat and humidity create near-constant conditions for microbial growth, this coating is a critical layer of defense.

Why Full HVAC System Cleaning Matters

Contaminants that accumulate inside HVAC systems don't stay there — they recirculate through your air supply every time the system runs. Dust, mold spores, and bacteria distributed through ductwork can worsen allergies, trigger respiratory symptoms, and degrade the overall indoor air environment for occupants.

Beyond air quality, dirty HVAC components force your system to work harder. Fouled coils and restricted blowers reduce efficiency, increase energy consumption, and shorten equipment lifespan. Regular cleaning restores performance and protects your investment.

When to Schedule HVAC System Cleaning

HVAC cleaning is recommended as part of routine maintenance planning in high-humidity environments — and becomes urgent in the following situations:

  • Visible mold on or around vents or HVAC components

  • Musty or stale odors when the system is running

  • Worsening allergies or respiratory symptoms among occupants

  • Following any flooding, water intrusion, or storm damage

  • After any extended period without HVAC operation

HVAC Cleaning Faq

  • Duct cleaning focuses on the ductwork itself — the channels that carry air through your home or building. HVAC system cleaning is more comprehensive: it includes the ducts plus the mechanical components of your air handler, specifically the coil and blower assemblies. These mechanical parts are significant sources of contamination and inefficiency when neglected, so a full system clean delivers better results than ductwork alone.

  • For a typical residential system, the full process generally takes between 4 and 8 hours. Larger or more complex commercial systems will require additional time. IAQ Services will provide a specific estimate based on your system configuration before work begins.

  • Given New Orleans' heat, humidity, and heavy year-round air conditioning use, a full HVAC system cleaning every 2 to 3 years is advisable for most properties — more frequently if there has been water damage, storm activity, or visible mold. NADCA's general recommendation is every 3 to 5 years, but local climate conditions shorten that window considerably.
