Frequently Asked Questions
How much does HVAC ductwork installation cost in Toronto?
HVAC ductwork installation in the GTA typically costs $3,000-$8,000 for a single-zone addition or retrofit, and $8,000-$15,000 or more for a complete whole-home system. Costs vary based on home size, duct material, accessibility, and whether the home is new construction or a retrofit. Retrofitting ductwork into older Toronto homes that originally had radiator or baseboard heating adds complexity due to limited chase space.
How often should ductwork be cleaned in a GTA home?
Professional duct cleaning is recommended every 3-5 years for most GTA homes, or immediately after a renovation involving drywall sanding, demolition, or flooring installation. NADCA-standard cleaning uses truck-mounted vacuum systems and costs $300-$700 for a standard residential system. Avoid $99 duct cleaning offers -- these services typically clean only the first few feet visible from each register.
Do I need a permit for ductwork installation in Toronto?
In most cases, yes. The City of Toronto and GTA municipalities require building permits for new HVAC ductwork installations and major modifications. Ontario Building Code Part 6 governs mechanical installations. Minor repairs and duct cleaning do not typically require permits, but adding new duct runs, installing make-up air systems, or rerouting exhaust venting generally do.
How do I know if my ductwork needs repair or replacement?
Common signs include rooms that are consistently too hot or too cold, unusual noises when the HVAC runs, visible duct damage in the basement, excessive dust despite regular cleaning, higher-than-expected energy bills, and musty odours from the vents. Galvanized steel ducts in pre-1980 Toronto homes corrode from the inside out, and a duct system leaking 30% or more of conditioned air is common in older GTA homes.
