How much does ductwork replacement cost in Toronto?

Ductwork replacement in Toronto typically ranges from $3,500-$8,000 for an average home, with costs varying significantly based on your home's size, accessibility, and the complexity of your HVAC system.

The cost breakdown for ductwork replacement in the GTA depends on several key factors. For a typical 1,500-2,000 square foot home, expect to pay $4,500-$6,500 for complete ductwork replacement using standard galvanized steel or flexible ducts. Larger homes (2,500+ square feet) or those requiring premium materials like insulated rigid ducts can push costs to $8,000-$12,000. These prices reflect current Toronto market rates, which typically run 15-20% higher than other Ontario cities due to labor costs and demand.

Material choices significantly impact your total cost. Flexible ducts are the most economical option at $8-12 per linear foot installed, while rigid galvanized steel runs $12-18 per linear foot. Insulated rigid ducts, which offer better energy efficiency and noise reduction, cost $15-25 per linear foot. Most Toronto homes require 200-400 linear feet of ductwork, depending on the layout and number of zones.

Accessibility plays a major role in pricing. Homes with easily accessible basements or crawl spaces fall on the lower end of cost ranges, while homes requiring drywall removal, working in tight spaces, or navigating around existing utilities can increase labor costs by 30-50%. Century homes common in neighborhoods like Cabbagetown or The Beaches often present accessibility challenges that drive up costs.

Professional installation is essential - ductwork affects your home's energy efficiency, air quality, and HVAC system performance. In Ontario, while ductwork installation doesn't require specific licensing, it should be done by TSSA-certified HVAC contractors who understand proper sizing, sealing, and integration with your heating and cooling systems. Poorly installed ducts can reduce HVAC efficiency by 20-40% and create humidity issues.

Your next steps should include getting quotes from at least three licensed HVAC contractors who can assess your specific situation. They'll evaluate your existing system, measure your home's heating/cooling load, and recommend appropriate duct sizing and materials. Most reputable contractors offer free estimates and can often complete ductwork replacement within 1-2 days for standard installations.
