If there is poor airflow, an HVAC system works twice as hard. As a result, it eats more energy and becomes more vulnerable to damage and breakdown.

Airflow restrictions cause a variety of factors, including:

  • Dirty air filter
  • Closed or obstructed registers
  • Closed duct dampers
  • Debris in the ductwork

Return ducts that are leaking
