Exhaust Fan Installation in Vaughan

How Exhaust Fan Installation Works

1. 1

   Assessment & venting check

   We check your existing fan’s wiring and switch setup and, critically, where the duct actually terminates, since a disconnected or attic-vented duct is a common hidden issue.

2. 2

   Fan & circuit planning

   We size the fan in CFM to the room and help you choose between a standard, humidity-sensing, or fan/light/heater combo unit, then confirm whether a dedicated circuit or switch leg is needed.

3. 3

   Installation & duct routing

   We install the fan housing, run or correct the ductwork to a proper exterior vent cap, and wire it to its own switch or sensor control.

4. 4

   Testing

   We test airflow and confirm the duct is fully sealed and venting outside before we consider the job done, not just that the fan spins.

Frequently Asked Questions

We’re building a large custom kitchen in Kleinburg — does the range hood need more than just a plug?

For a large custom hood, yes. Beyond the dedicated circuit, we look at make-up air requirements so the hood doesn’t depressurize the house or pull combustion gases back from a fireplace or furnace, which is a bigger consideration in larger custom kitchens than a standard-size hood.

Our Maple builder-grade bathroom fan is loud and doesn’t have a timer — is upgrading worth it?

It’s one of our most common calls in Maple. Since the ducting in these newer subdivisions is usually already correct, it’s typically just a fan swap to a quieter, independently-switched humidity-sensing unit.

Why does my bathroom still feel humid after running the exhaust fan?

This usually means the fan is underpowered for the room or, more often, that the duct isn’t actually venting outside. We check where your ductwork terminates as part of every assessment, since a disconnected or attic-vented duct is a surprisingly common issue.

Do I need a dedicated circuit for a new exhaust fan?

Not always. Many bathroom fans can run on a shared switch leg with the lighting, but a humidity-sensing or timer-controlled fan usually needs to operate independently, which we can wire as part of the installation.

Can you install an exhaust fan where there isn’t one currently?

Yes, including running new ductwork to a proper exterior vent cap and wiring a new switch or sensor control, for bathrooms or kitchens that were never fitted with one.

Is my home required to have a bathroom exhaust fan?

The Ontario Building Code requires mechanical ventilation in any bathroom without an operable window. Older homes sometimes predate this requirement or had a fan added without a permit, which we can assess and correct.

How much does exhaust fan installation cost?

Cost depends mainly on the ducting: whether an existing vent run can be reused, how far the fan is from an exterior wall or roofline, and whether a dedicated circuit is needed. We provide a clear quote after seeing the space.
