Signs Your Ducts Are Leaking — And What to Do About It
A typical GTA home loses 20–30% of conditioned air through leaking ductwork. This adds hundreds of dollars per year to heating and cooling bills.
Signs You Have Leaking Ducts
- Rooms that are always too hot or too cold — Uneven comfort despite a running furnace/AC
- Higher energy bills — Especially if bills increased without a rate change
- Excessive dust near vents — Leaking ducts draw dust from unconditioned spaces (attic, crawlspace)
- Visible gaps or disconnected duct joints in basement or attic
- Musty or chemical smells — Ducts pulling air from garage or crawlspace
Duct Sealing Solutions
- Mastic sealant — Best for sealing joints and gaps; durable, flexible, non-hardening
- Metal foil tape — For accessible joints (avoid cloth duct tape which dries out)
- Aeroseal (pressurized sealant) — Seals inaccessible leaks from inside the duct system
