Duct cleaning, room pressure, airflow & COVID-19 spread

Ventilation-&-Airflow-Audit-

If more air is removed through the exhaust than what is supplied through the supply, the room will have negative air pressure. In this case, adjacent rooms & corridors can have different air pressures. If a door between the two spaces is opened, air will flow between them. Room air pressure can change over time and can depend on the cleanliness of air ducts.

Ventilation & Airflow Audit

1) Baseline testing

We'll measure airflow and pressure difference between rooms and corridors. This measurement will be used to establish:

  • The effect duct cleaning (see step 2) has on the building airflow.
  • A baseline airflow record to establish the original airflow plan designed by the buildings' engineers.

2) Duct & hvac cleaning

If more air is removed through the exhaust than what is supplied through the supply, the room will have negative air pressure. That balance can change, and can even be reversed if air ducts are not cleaned properly.

We'll compile post-cleaning evidence which can include:

  • photographic evidence,
  • video evidence,
  • written inspection summary.

If you are in any doubt that duct buildup restricts airflow, take a look at this video:

 

3) Room & corridor airflow re-testing

We'll then re-measure airflow and pressure difference between rooms and corridors. This measurement will be compared against the measurements in step 1 and any other past records to establish:

  • The effect duct cleaning in step 2 has on the building airflow.
  • A baseline airflow record to establish the original airflow plan designed by the buildings' engineers.
 

3) Ongoing duct cleaning plan

We'll take all the information we've collected in step 3 to 4, as well as your individual circumstances, and develop a plan to ensure your business and every person using your building is safe.
