Can you replace all the ductwork in a house?
Yes. We install complete supply and return systems for renovations and new construction, as well as targeted corrections when the existing layout can be improved.
Heating and cooling service
Ductwork and ventilation
Comfort problems often start with the air distribution. We handle the duct and ventilation work that supports the equipment.
How we can help
Move the right amount of air to every room.
Ottaway Mechanical installs new duct systems and corrects accessible supply, return and ventilation problems in homes and small commercial properties. We also handle bath exhaust, kitchen exhaust connections and mechanical ventilation within the HVAC scope.
Oversized equipment cannot overcome undersized returns, poor branch layout or disconnected ductwork. We look at the path the air must travel and build a correction around actual airflow needs rather than simply adding a larger unit.
What we look at
The whole system matters.
- Available equipment airflow
- Supply and return trunk capacity
- Branch sizes and room requirements
- Filter and return-grille restrictions
- Accessible leakage, insulation and termination points
Straight answers
Equipment and ductwork have to work together
When airflow is the real problem, replacing equipment alone can leave the same hot rooms, noise and high static pressure. We explain which duct corrections are necessary, which are optional and how they affect the complete system.

Ductwork & ventilation FAQs
Can bad ductwork make a new system perform poorly?
Yes. Restricted returns, undersized trunks, excessive flex or poor branch layout can reduce capacity, create noise and shorten equipment life.
Do you install bathroom exhaust and ventilation?
Yes. We install bath-fan ducting, kitchen exhaust connections and other mechanical ventilation when they are part of the project scope.
Service and diagnostic visits are paid. Estimates for full equipment replacement or new installation are free.
