• Analysis: The collected data from the above measurements are then analyzed to determine if the system delivers the required airflow for heating or cooling needs.
  • Adjustments: If airflow falls short of expectations, adjustments become necessary. These adjustments might involve cleaning or replacing filters, resizing ducts, or re-calibrating the blower fan.
  • Verification: Finally, another round of testing confirms that the adjustments effectively improved airflow.

The Benefits for HVAC Contractors

For HVAC contractors, incorporating airflow testing and diagnostics into their service offerings can lead to several advantages:

  • Competitive Edge: Offering comprehensive HVAC services, including airflow testing, sets contractors apart from the competition. Customers are more likely to choose a contractor who can provide a holistic solution.
  • Customer Satisfaction: Homeowners enjoy better comfort and lower energy bills when HVAC systems operate optimally. Satisfied customers are more likely to become repeat clients and refer the contractor to others.
