ClearVu provides full-service air efficiency testing and mitigation through Blower (Large Fans) Door Testing and air-tightness evaluations.

ClearVu Environmental Services offers blower door tests, a diagnostic tool used to assess the airtightness of homes or buildings. During the test, a trained energy professional mounts a powerful fan into an exterior doorway, either pulling air out or increasing air pressure inside. This process reveals unsealed gaps where outside air flows in or indoor air leaks out. Tools like infrared cameras or smoke pencils may be employed to pinpoint specific areas of insulation gaps or air leaks. The test measures the air infiltration rate, helping to reduce energy consumption, prevent moisture issues, eliminate drafts, control contaminants, determine HVAC equipment requirements, and assess indoor air quality needs. Blower door equipment includes a frame, flexible panel, variable-speed fan, digital pressure gauge, and airflow measurement device. Calibrated blower doors provide accurate airflow measurements, essential for assessing overall tightness and guiding improvements for energy efficiency and comfort.
