Professional Duct Cleaning Designed for Building Performance
As a property or facility manager, you’re responsible for maintaining the health, comfort, and safety of everyone in your building. A clean HVAC system plays a key role in achieving those goals.
At Pro Tech Commercial Air Duct Cleaning of St. Louis, we make the process transparent, efficient, and compliant—so you can schedule service with confidence and minimal disruption to daily operations.
The Importance of Clear Communication and Planning
Before any cleaning begins, our team conducts a comprehensive system inspection to map out your HVAC layout and determine the best access points. We’ll review building use, scheduling preferences, and safety protocols to create a custom cleaning plan that fits your facility’s needs.
Our pre-cleaning communication includes:
Full system evaluation and inspection report
Service scheduling and work area coordination
Safety, containment, and access plan
Documentation of equipment, filters, and duct zones
Step-by-Step: What Happens During a Commercial Duct Cleaning
1. System Preparation and Containment
We isolate the HVAC zones being cleaned to prevent cross-contamination. Drop cloths, HEPA vacuums, and containment barriers are installed to protect occupied areas and equipment.
2. Negative Air Pressure Setup
Using industrial-grade HEPA vacuum systems, we place the duct system under negative pressure. This ensures all loosened contaminants are captured safely and efficiently.
3. Source Removal Cleaning
Our technicians use high-powered agitation tools and compressed air whips to dislodge dust, debris, and buildup from every section of the ductwork.
This includes air handlers, supply and return ducts, coils, and registers.
4. Antimicrobial and Deodorization Treatment
EPA-registered antimicrobial agents are applied to eliminate mold spores and odor-causing bacteria. This step helps prevent future growth and keeps your indoor environment fresh.
5. Coil and Component Cleaning
Evaporator coils, fans, and blower compartments are cleaned to restore peak system efficiency and ensure even airflow distribution.
6. Post-Cleaning Inspection and Verification
Once cleaning is complete, we perform visual and instrument-based inspections to confirm results. You’ll receive detailed before-and-after documentation and system condition reports for your records.
