Do kitchen exhaust fans need to be vented outside?

Range hoods do not have to be vented to the outside. But, ducted range hoods are almost always preferred over ductless hoods. They remove all the smoke and cooking exhaust from your kitchen, while ductless hoods recirculate your cooking exhaust back into your kitchen.

How do you vent a range hood on an outside wall?

Attach a wall or roof cap to the exterior wall or roof.

1. Determine where you want to vent your range hood.
2. Install your ductwork in the shortest unobstructed path to the outside of your home.
3. Cut a hole 1-2 inches larger than your ductwork where you’ll run the duct from your hood.
4. Attach the range hood to your ductwork.

Can you vent a kitchen exhaust fan into the attic?

No, you should never vent your range hood into the attic. The excess buildup of grease and moisture in your attic will ruin it and over time may cause mold damage. Instead, vent your hood through an interior wall or through the ceiling all the way outside of your home.

How do you vent a kitchen exhaust fan?

The best option is to vent vertically through the roof if possible, since hot air rises. But this is not required. Vent through a side wall if you cannot vent directly above your hood. To have a smooth installation, find a great contractor to install your ductwork.

What is the best way to vent a range hood?

Range hoods are vented up through the roof or out through an exterior wall. Look for a metal duct going through the cabinets above or an exhaust cap on the exterior wall behind the range hood. You should feel air being blown out of the exhaust cap on the roof or wall when the fan is running.

Do exhaust fans bring in outside air?

Yes, any time you operate a bathroom exhaust vent fan you are removing stale (conditioned) air from inside and replacing it with outdoor air. The purpose of the bathroom exhaust fan is to remove excess moisture and odors from the bathroom.

Where should a kitchen exhaust fan be placed?

The exhaust fan is typically located directly over the kitchen stove and is installed in a range hood or cabinet, integrated with a microwave oven, or mounted on the wall. The fan should be ducted to exhaust outside of the home, not into the attic, crawlspace, or another area inside the building.

How do you vent an outside stove?

If your stove is near an exterior wall, the fastest way is to go through the wall. Other vents have to go up through the roof. If your home has a chimney, you can often connect the vent pipe to the chimney instead of creating another hole in an exterior wall.

Does a cooker hood have to be on an outside wall?

Recirculating hoods can be installed almost anywhere in a kitchen because they don’t need to be connected to an external wall. Most cooker hood styles can be configured to either ducted extraction or recirculation, so there’s a good selection of models to choose from for your kitchen.

Can you vent an exhaust fan through soffit?

To clear out any confusion, soffit is the underside area of the roof overhang or eave. It is possible to vent your bathroom fan through the soffit and avoid making a hole in the roof. Usually, a hole in the roof may lead to leaks and other problems.

Are ventless hoods any good?

Unvented range hoods do filter some grease and cooking odors from the air, but the general consensus is that they’re nowhere near as effective. Nor do they remove heat and humidity, so they won’t help keep your kitchen cool while you cook.

Can you vent range hood through soffit?

You must not vent into the soffits, or even under the soffits unless you are more than a foot and a half below the soffit to allow the wind to dissipate the moisture before it rises back up into the attic.
