Bathroom exhaust fan installation and repair, brampton

The job of a bathroom exhaust fan is to remove moist air and foul odors from the bathroom. When moist air is carried through a duct that passes through a cold attic space, condensation will occur inside the duct. When enough condensate accumulates, it drains to the bottom, leaks through the fan and lives water stain on ceiling. Use an insulated duct inside the attic, make sure the duct is tightly connected to a roof cap with a damper. Improper installation can lead problems.

Venting a exhaust fan in to the attic create a lot of moisture . In cold weather the moisture will condense on the underside of the roof, dripping into the insulation and potentially causing rot or leaking.

Air shall not be exhausted into an attic, soffit, ridge vent or crawl space. ... You certainly CAN run the vent THROUGH a soffit. Then the vent terminates outside. So, then the argument is that your humid bathroom exhaust comes out and is sucked back into the attic by the soffit vents built into most roof/attic systems

If you have two bathrooms that are close together and one has an exhaust fan and the other doesn’t, you might be wondering if you can tie a new exhaust duct into the existing one. Well, you can’t! You’d often blow air from one bathroom into the other, and local building inspectors wouldn’t approve it.

Exhaust fans perform an important function by removing excess moisture from your home. When venting a bathroom exhaust fan, kitchen range hood or laundry dryer make sure to vent the air to the outside, rather than into your attic where it can cause leaking conentation, mold and mildew to form .
