How often should ductwork be replaced?

Ductwork typically lasts 15-25 years, but replacement timing depends more on condition than age. Well-maintained ducts in good condition can last decades, while poorly installed or damaged ductwork may need replacement much sooner.

Signs your ductwork needs replacement include visible damage like holes, disconnected joints, or crushed sections, excessive dust throughout your home despite regular cleaning, uneven heating or cooling between rooms, and significantly higher energy bills without explanation. If your ducts are located in unconditioned spaces like crawlspaces or attics and lack proper insulation, replacement with properly insulated ductwork can dramatically improve efficiency.

In Ottawa's climate, ductwork faces unique challenges from our extreme temperature swings and high humidity summers. Ducts in older homes (pre-1980s) often lack adequate insulation and may have been installed with materials that don't meet current standards. Many Ottawa homes have ductwork running through unheated basements or crawlspaces, where poor insulation leads to significant energy loss during our cold winters.

Professional duct inspection can determine if your system needs replacement or if repairs and sealing will suffice. A TSSA-licensed HVAC technician can assess your ductwork's condition, check for proper sizing, and identify any code compliance issues. Sometimes what appears to need full replacement can be addressed with strategic repairs and professional sealing.

Before considering replacement, have your ducts professionally cleaned and inspected. This service typically costs $400-800 in Ottawa and can reveal the true condition of your system while improving air quality and efficiency. If replacement is needed, expect costs of $3,000-8,000 depending on your home's size and complexity.
