What the hood ducting and fan installation
involves.

A hood ducting and fan installation is where a kitchen's ventilation is decided, because the fan the maker rates can only do its job through the duct it is given. It covers wall chimney hoods, island hoods, insert liners inside custom cabinetry, under-cabinet hoods, downdraft units behind a cooktop and over-the-range microwaves with a vented fan. The plan starts with the duct: the diameter the instructions call for, never reduced along the way; the shortest route to the outside, through the wall or the roof; as few elbows as possible; and a wall or roof cap with a damper that opens freely and closes against drafts. The hood is mounted at the height above the cooking surface its maker specifies, level and square to the counter, on blocking or a bracket that carries its weight. The ducting joints are sealed, and a run through cold space is insulated so grease-laden moisture does not condense inside it. Stronger fans raise the makeup air question: many local codes require outside air to replace what a large hood removes, and a house with a gas water heater or a fireplace has to be checked for backdraft. A recirculating model gets its charcoal filters. Power is a receptacle in the chimney or a junction box that an electrician provides.

Swapping a hood onto an existing duct of the right size is the lighter case. A new route through a wall or roof, an island hood hung from the ceiling or ducting enlarged to meet a bigger fan takes much longer.

02

Mount the hood or liner level at the maker's height on framing or brackets strong enough for its weight.

03

Run the duct at full size to a wall or roof cap with a working damper, joints sealed and elbows kept few.

04

Connect the fan to the receptacle or junction box already provided, and fit charcoal filters on a recirculating model.

All service areas

Tampa BayFL · 31 areas

A new outdoor kitchen on a Tampa Bay lanai often gets its own hood, and hood ducting and fan installation there fits a unit rated for outdoor use and runs the duct so rain driven by summer storms cannot get into the fan.

OrlandoFL · 30 areas

Orlando builder kitchens often came with a recirculating microwave above the cooktop, and when a homeowner upgrades, hood ducting and fan installation there checks whether a real duct to the outside exists or can be added through the attic.

Miami / South FloridaFL · 47 areas

A new hood in a South Florida condo is usually hung under a cabinet over the old electrical box, and hood ducting and fan installation there sets it up for recirculation with the maker's charcoal kit, because the tower's walls cannot take a new duct.

New York MetroNY · 75 areas

In New York apartments a new hood usually cannot vent outside, so hood ducting and fan installation there fits a recirculating unit with the right charcoal filters, or connects to an existing building duct if the board has approved it.

HoustonTX · 36 areas

Houston's pro-style gas kitchens pair large burners with large fans, and hood ducting and fan installation there matches the duct diameter to the fan's outlet and flags when the maker or local code calls for makeup air in a tight new house.

ChicagoIL · 50 areas

Chicagoland hoods that vent through an outside wall face hard winters, and hood ducting and fan installation there fits a damper that closes firmly and a wall cap that keeps cold air and snow from coming back down the duct.

Los AngelesCA · 95 areas

In Los Angeles hillside houses a hood often vents through a roof above a vaulted ceiling, and hood ducting and fan installation there sizes the duct to the fan, seals every joint with foil tape and sets the cap to shed rain.

San DiegoCA · 31 areas

San Diego's coastal kitchens often open onto a patio, and hood ducting and fan installation there places the outside cap away from doors and windows so smoke leaves the house instead of drifting back in on the breeze.

San Francisco Bay AreaCA · 74 areas

Bay Area induction remodels still need a hood, and hood ducting and fan installation there often reuses the old gas-era duct, checking that its diameter and route suit the new fan before the insert is fixed in the cabinet.

Questions about
the hood ducting and fan installation.

Can a new hood be connected to the smaller duct from the old one?
Reducing the duct below the size in the instructions chokes the fan, makes it louder and cuts the airflow it was bought for. The duct is enlarged to the required size where it can be reached, or a hood is chosen to suit the duct.
What is makeup air, and when is it needed?
It is outside air brought in to replace the air a hood removes. Many residential codes require it above a set fan rating, often around four hundred cubic feet per minute, and your local building department has the exact rule.
Is a recirculating hood a real alternative to ducting outside?
Where no duct route exists, a recirculating hood with charcoal filters catches grease and some odor. It returns the heat and moisture to the kitchen, so a ducted hood is preferred wherever a path outside can be made.
