How much does ductwork cost in Ontario?
Sealing only: $400-$1,200. Return upsize: $400-$1,500. Full replacement: $25-$55 per linear foot ($2,500-$8,500 typical 80-200 ft layout). HEPA duct cleaning: $400-$800 for logistics-corridor properties.
My South Ontario home has small ducts. Can you fix that?
Yes. Pre-1980 South Ontario homes often have undersized return ducts that strangle modern variable-speed blowers. We upsize or add a second return run as a separate line item, typically $400-$1,200, often the actual fix instead of full system replacement.
My Ontario home is near the airport. Should I clean my ducts more often?
Yes. Logistics-corridor diesel particulate and fine dust accumulate inside supply ducts faster than residential-only cities. Annual HEPA-cabinet duct cleaning ($400-$800) recommended for properties within 1-2 miles of airport approaches or major truck corridors.
Should I seal or replace my Ontario ducts?
Depends on duct condition. Sealing fixes 20-30% air loss when existing ducts are properly sized and intact. Replacement needed when insulation is degraded, ducts are undersized for modern equipment, or rodent contamination is present.
How much does ductwork cost in the High Desert?
Sealing-only jobs run $25-$35 per linear foot. Partial replacement (bad runs only) $35-$45. Full replacement with R-8 insulated flex $45-$55. Average HD home has 100-200 linear ft of duct, so total jobs typically $2,500-$11,000.
How do I know if my ducts need replacing?
Signs include: rooms that never reach setpoint, high summer electric bills, dust accumulation around registers, visible duct sag, and uneven temperatures between rooms. We measure static pressure and inspect with camera to confirm.
Is duct cleaning worth it?
DOE notes that routine duct cleaning rarely improves indoor air quality on its own. Worth it after rodent contamination, post-fire smoke, or major remodels that left construction dust behind. Not a substitute for a clean filter.
