Toronto

What ductwork looks like in Toronto.

Toronto's housing mix — from Victorian semis to postwar bungalows to new infills — means every install is different. We plan for chimney-liner requirements, tight mechanical-room footprints, and the venting constraints that come with older homes.

Call us when:

  • Some rooms are boiling, others are freezing
  • The furnace runs constantly but the house is still uncomfortable
  • Vents blow cold air even when the furnace is running
  • Energy bills don't match the equipment's efficiency rating
  • You just finished a basement, addition, or reno and need duct rework
  • Visible tears, mouse damage, or disconnected duct sections

FAQ

Ductwork in Toronto — your top questions

My furnace is brand new but one room is still cold — why?
Almost always ductwork: undersized returns, a closed or blocked damper, a kinked flex run, an unbalanced system, or a leaky run dumping conditioned air into the attic. Equipment upgrades can't compensate for duct problems.
What is Aeroseal?
A process that pressurizes your ducts and injects an aerosolized sealant that plugs leaks from the inside. Great for inaccessible runs (slab-embedded, walled-in). Not necessary for most homes with accessible basement ductwork — mastic works fine there.
How do I know if my ducts are undersized?
Telltale signs: high static pressure on the furnace, whistling vents, loud blower, short-cycling, or rooms that just never get comfortable. A static pressure test at the service call tells us in about 5 minutes.
