Often Asked Questions

How often should I have my air ducts or vents cleaned?
It's typically recommended every 3–5 years for air ducts and at least once a year for dryer vents — though it depends on factors like pets, allergies, and household size.
How long does a typical service take?
Most residential jobs take 2–4 hours, depending on the size of the home and the type of service requested.
Will there be any mess left behind after the service?
No — we use professional equipment and protective coverings to keep your home clean. We always leave the work area tidier than we found it.
How do I know if I need duct or vent cleaning?
Common signs include visible dust around vents, increased allergies, longer dryer cycles, or musty odors when your HVAC runs.
