A closer look
Look beyond the room that feels warm
Poor airflow may begin with a restricted filter or blocked return, but duct leaks, damaged ducts and blower issues can also affect comfort. The pattern matters: one room behaving differently points to a different investigation than weak airflow throughout the home.
We review the affected rooms and the accessible air path before proposing changes. Closing many supply vents can worsen pressure problems, so avoid using that as a permanent solution.
Common causes of poor airflow
- A dirty or clogged air filter
- A dirty evaporator coil or blower wheel
- Leaky, crushed, or disconnected ducts
- Closed or blocked vents and returns
- A failing blower motor or capacitor
- Ductwork that is undersized for the system
What you can check first
Check the air filter and replace it if it is dirty. Make sure supply vents and return grilles are open and not blocked by furniture. If airflow is still weak, the cause is likely inside the system or ductwork and needs a technician.
How we find the problem
Check the equipment
We inspect the filter, blower, coil and controls.
Check the ductwork
We look for leaks, restrictions and imbalance that keep air from reaching your rooms.
