Aeroseal duct sealing typically takes a half-day to a full day for a single-family home — usually 4 to 8 hours from setup to teardown. The Aeroseal aerosol injection itself runs for about an hour once the ducts are pressurized; the rest of the time is dedicated to prep, sealing registers, and verification testing.

What to expect

  • Initial duct-leakage measurement
  • Mask off every supply and return register
  • Connect Aeroseal machine to the duct system
  • Inject the sealant aerosol while monitoring leakage in real time
  • Final leakage measurement and certificate

The process is sealed-system, computer-controlled, and verifiable. Schedule through our Aeroseal duct sealing service, often paired with duct cleaning or duct inspection.
