Not every finished home is ready for move-in without a few surprises. In South Salem, we were asked by the GC to provide blower door and duct leakage tests. The blower door test passed but we found (4) four new HVAC systems that failed their duct leakage tests after all the sheetrock was up and the house was 99% complete.
We tackled the problem and removed construction dust and debris from the duct work with a full duct cleaning, sanitizing. We then performed the Aeroseal duct sealing process. Each system was pressure-tested, sanitized, and then sealed from the inside using non-toxic materials—no need to cut into finished walls. Our process meant every vent was removed, every duct was inspected, and the final results showed a 97% improvement in system efficiency.
Clean, sealed ducts now mean fresher air and better comfort for this home. Reach out if you want to know how clean your air ducts really are.
