Frequently Asked Questions
How do I know if my ducts are leaking?
Uneven temperatures, weak airflow and higher bills are common signs. A technician can inspect accessible ductwork and check airflow.
Can you add ducts to a finished basement?
Often, yes. We assess the space and recommend the best route — or suggest a ductless option where ducts are not practical.
Do new systems need new ductwork?
Not always. Many installs reuse existing ducts, but some need modifications to match the new equipment.
Do you work on commercial ductwork?
Yes, we handle both residential and commercial projects.
