Service
Ductwork & Ventilation Services in Ottawa
Even the best furnace or AC underperforms on leaky, poorly balanced ductwork. We run new duct branches, modify existing layouts for renovations, and install venting for bathroom fans, kitchen hoods, and laundry appliances — sealed and balanced so air actually reaches every room.
Signs you might need this
- Some rooms are noticeably hotter or colder than others
- You're renovating and need ducts moved, added, or capped
- A bathroom fan or range hood vents into the attic instead of outside
- Noticeable dust, noise, or airflow loss at certain vents
Before you book
Planning work around a renovation
Provide any available floor plans and explain which rooms, walls or appliances will move. Discuss access to existing ducts, the proposed work and how the schedule fits with other trades before booking.
Defining the scope of your quote
Ask which duct runs or ventilation connections are included, whether access openings are required and who is responsible for restoring finishes. If particular rooms are uncomfortable, describe when the problem occurs so the assessment can address those rooms.
