CryoDucts™ is a proprietary CO₂-based ventilation treatment process designed to support cleaner, safer indoor environments in San Antonio — without chemicals, added moisture, or residue.

How the CryoDucts™ Process Works

Our trained technicians follow a structured, professional approach to ensure safe and effective treatment of your HVAC system.

We begin with a detailed inspection of your HVAC unit and accessible ductwork, including:

  • Supply and return areas
  • Visible duct interiors
  • Signs of dust, moisture, or contamination


If needed, we document conditions for transparency and reporting.

Before treatment:

  • HVAC system is safely powered off
  • Equipment is prepared and secured
  • Work area is evaluated for proper ventilation


Our technicians use specialized tools and protective equipment to ensure a controlled process.

Using proprietary CryoDucts™ equipment, we introduce a controlled application into the duct system.

This process:

  • Reaches internal duct surfaces
  • Provides consistent, targeted coverage
  • Supports reduction of contaminants within the airflow system


The treatment is applied methodically across accessible sections of the HVAC system.

One of the key advantages of CryoDucts™:

  • No chemicals used
  • No moisture introduced
  • No residue left behind


This helps maintain system integrity while supporting indoor air quality.

After completing the process:

  • All access panels are securely closed
  • Final inspection is performed
  • System is confirmed safe for operation

Before departure, our technician will:

  • Explain the completed service
  • Answer any questions
  • Provide maintenance recommendations
