Duct Leakage and Duct Cleaning Services
Smoke-Based Duct Leakage Testing for Precise Detection & Repair
Locate, Document & Eliminate Hidden Air Leaks in HVAC Duct Systems
Thorough Smoke Testing for Leak Detection & System Efficiency
we provide complete duct leakage testing using smoke to visually identify and document air leakage points throughout your HVAC system. This allows our clients to quickly take corrective actions and improve the performance, energy efficiency, and safety of their building’s air distribution systems.
How Our Duct Leakage Testing Works?
Our testing setup includes a calibrated fan, a pressure monitoring device, and a sealing system for supply and return registers. We begin by sealing all but one register or return vent using adhesive tape, reusable seals, or panels. A calibrated fan is then connected to the remaining open vent. As the fan delivers air into the system, we monitor pressure levels in a branch of the ductwork. Any air escaping through seams, joints, or unsealed points in the ductwork becomes visible thanks to the introduction of a non-toxic, highly visible smoke.
Why It Matters:
- Improves HVAC System Efficiency by eliminating air loss
- Enhances Indoor Air Quality by preventing the intake of dust or contaminants from attics, crawlspaces, or mechanical rooms
- Reduces Energy Costs by minimizing pressure imbalances
- Ensures Compliance with modern energy codes and building performance standards
Testing Approaches
- We offer both pressurization and depressurization testing, depending on your building’s layout. For ducts located outside of the conditioned envelope (like in attics or crawlspaces), we recommend pressurization testing to prevent contaminants from entering the system during evaluation.
