Supply airflow
Registers and supply ducts deliver conditioned air.
Restriction, leakage, poor sizing, or balancing problems can limit room comfort.
Ductwork, Airflow, and Ventilation
Comfort depends on moving the right amount of air to and from each part of the home.
Return airflow
The system must be able to bring enough air back to the equipment without excessive restriction or room pressure problems.
Duct leakage
Leaks can lose conditioned air, draw contaminants into the system, and create pressure or comfort issues.
Ventilation
Fresh air strategies should balance indoor air quality, moisture, energy use, and equipment capacity.
