Questions about ductwork?

How do I know if my ducts are leaking?

Signs of leaky ducts include uneven temperatures, high energy bills, excessive dust, and rooms that are hard to heat or cool. A professional duct test can measure exactly how much air you're losing.

How much does duct sealing cost?

Duct sealing in the East Bay typically costs between $1,000 and $3,000 depending on accessibility and extent of leaks. The energy savings often pay for the service within 1-2 years.

Should I clean or replace my ducts?

Duct cleaning is sufficient for most homes. Replacement is recommended if ducts are severely damaged, poorly designed, or more than 25 years old with deteriorating insulation.
