Weak Airflow From Vents
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Dirty Air Filter
The most common cause of reduced airflow.
Blower Motor Issue
Reduced fan speed or a failing motor.
Duct Restriction
Blockage, damage, or closed dampers limiting flow.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
Could this be affecting my energy bills?
Yes — restricted airflow makes the system work harder and less efficiently.
Is a dirty filter really the cause that often?
It's the single most common cause — worth checking and replacing before assuming a bigger issue.
