Blower door and duct leakage testing
We provide blower door testing for multifamily buildings and homes, with duct leakage testing when required by your code or certification program.
Find out where the air is going
Blower door testing measures air leakage through the building enclosure. Duct leakage testing measures air lost from the duct system. Oxalis schedules the test, records the results, and helps your team plan corrections when a target is not met.

Common questions
When should testing be scheduled?
Schedule testing when the enclosure or duct system is ready. Leave time in the construction schedule for corrections and another test if needed.

Oxalis records the result, discusses likely leakage paths or site readiness issues, and helps your team plan corrections and another test.
