Our process follows industry best practices using commercial-grade equipment and a proven step-by-step approach:
1. System Evaluation
We begin with a detailed, non-invasive inspection of your HVAC system‘s ductwork and vents. This ensures we understand the condition of your system before any work begins.
2. Register Removal & Protection
All supply and return vents are carefully removed. We protect surrounding surfaces and clean each register before reinstalling them.
3. Source Removal Duct Cleaning
We use powerful HEPA-filtered negative air machines combined with mechanical agitation tools to remove built-up dust, debris, and contaminants from your duct system.
4. Air Handler Cleaning (Standard Service Included)
We perform a dry mechanical cleaning of key air handler components, including:
• Blower compartment
• Cabinet interior
• Return plenum
This level of cleaning is included and is sufficient for most residential systems.

When Is a Deeper Cleaning Needed? (No Pressure, Just Transparency)
In some cases, we may find heavier buildup inside the air handler that cannot be fully addressed with dry cleaning alone.
If that happens, we may recommend a deeper wet cleaning—but only if it’s genuinely needed.
This is:
✔ Not automatically included
✔ The only additional service we may suggest
✔ Always optional and approved by you first
We’ll show you exactly what we’re seeing and explain everything clearly before any additional work is considered.
If approved, the deep cleaning includes:
• Removal and wet cleaning of the blower wheel
• Evaporator coil cleaning using coil-safe, manufacturer-approved, cleaning solutions specifically formulated for HVAC evaporator coils.
• Drain pan cleaning
• Interior cabinet surface cleaning
Most systems don’t require this—but when they do, it can significantly improve cleanliness and performance.

At Orca Air Services, your comfort and system performance are our top priorities. That’s why every duct cleaning we perform includes sealing the register boots with Foster® 40-20, a professional-grade antimicrobial coating designed to protect fiberglass duct board and flex boots — the most common materials used in Florida homes.
What Is Foster® 40-20?
Foster® 40-20 (First Defense®) is an EPA-registered antimicrobial coating specifically formulated for use on fiberglass HVAC components such as duct board, flex boots, and insulation. When applied, it forms a flexible, durable film designed to inhibit the growth of common surface microbes and help protect treated surfaces after cleaning.
Benefits of Register Boot Sealing with Foster® 40-20
• Helps Inhibit Microbial Activity
Designed for humid environments like Florida, where moisture can contribute to microbial activity on HVAC surfaces.
• Seals Porous Fiberglass Surfaces
Duct board and flex boots are porous and absorb moisture — this coating creates a protective barrier to reduce moisture and debris absorption.
• Improves Indoor Air Quality
Reduces airborne allergens, dust, and irritants associated with debris buildup on fiberglass HVAC materials.
• Supports Cleaner HVAC Surfaces
Adds an extra layer of surface protection for environments with sensitivity to airborne dust and particulates.
• Long Lasting Surface Protection
Once cured, Foster® 40-20 provides ongoing protection for treated HVAC surfaces under normal operating conditions.


• Protects HVAC Surfaces in Humid Conditions
Florida’s humidity can create conditions that allow moisture to accumulate on HVAC components. Sealing register boots helps reduce moisture exposure and support cleaner system surfaces.
• Seals Porous Fiberglass Surfaces
Duct board and flex boots are absorbent. This antimicrobial coating creates a barrier that helps reduce dust, debris, and moisture absorption.
• Improves Indoor Air Quality
Helps reduce dust, allergens, and other airborne particles that would otherwise be recirculated through your vents.
• Protects Your System Between Cleanings
Helps keep register boots cleaner between professional duct cleanings, with no additional steps needed on your part.
