Range hood vent installation typically costs between $300 and $1,500, depending on whether you're venting to the outside, the complexity of your ductwork, and whether you hire a professional or do it yourself.

The largest cost driver is ductwork routing. If your range hood can vent straight out through an exterior wall behind the stove, you'll pay less than if ductwork has to run through walls, ceilings, or across multiple rooms. A straightforward wall vent might cost $300 to $600 installed. Running ductwork through framing, attic space, or around obstacles can push the price to $800 to $1,500 or higher.

Labor makes up most of the expense. A professional installer typically charges $200 to $500 for labor alone, depending on local rates and job complexity. If you already own the range hood and just need installation, you're paying for the ductwork, venting materials, and labor. If you're buying a new hood and having it installed together, some appliance retailers bundle installation into the purchase price or offer it at a discount.

Recirculating hoods (which filter air and push it back into the kitchen instead of venting outside) cost far less to install—often $100 to $300—because they need no ductwork. However, they don't remove moisture or cooking odors as effectively as ducted vents.

Key Takeaways

  • Professional installation of a ducted range hood vent runs $300 to $1,500, with ductwork routing being the main cost variable.
  • Venting straight through an exterior wall costs less than running ductwork through walls, ceilings, or attic space.
  • Labor typically accounts for $200 to $500 of the total cost, and rates vary by region and installer.
  • Recirculating hoods need no ductwork and cost $100 to $300 to install, but they filter rather than remove air from the kitchen.
  • Getting a quote from a local HVAC contractor or appliance installer is the only way to know your actual cost, since ductwork complexity varies by house layout.

What ductwork routing adds to your bill

The path your ductwork takes from the range hood to the outside determines most of the installation cost. If your kitchen is on an exterior wall and the hood vents directly through that wall, the job is straightforward: cut an opening, install a wall cap, connect the hood to the duct, and seal it. This typically costs $300 to $600 installed.

If ductwork has to travel horizontally through walls or vertically through an attic or crawlspace before reaching an exterior wall, the cost rises. The installer has to cut openings in framing, run rigid or flexible ductwork, find it, and patch walls or ceilings afterward. A run of 10 to 20 feet through walls or attic space can add $300 to $700 to the labor cost alone.

Venting through a roof instead of a wall is more expensive because it requires flashing, roof penetration, and weatherproofing. Expect to pay $400 to $800 more than a wall vent. Venting into a soffit (the overhang under your roof) is cheaper than a roof vent but still costs more than a wall vent because it requires careful sealing to prevent moisture from entering the attic.

Labor costs by installer type

An HVAC contractor typically charges $150 to $400 per hour, with most range hood installations taking 2 to 4 hours. That translates to $300 to $1,600 in labor alone, though many contractors quote a flat rate for a standard installation rather than hourly. A flat-rate quote for a straightforward wall vent might be $200 to $400; a complex run through multiple rooms might be $600 to $1,000.

Appliance installation services (often available through the retailer where you buy the hood) typically charge $150 to $350 for installation. These services work well if you're buying a new hood and want everything handled in one transaction, but they may not handle complex ductwork modifications. Always ask whether the quote includes ductwork materials or just labor.

If you're handy and the ductwork is straightforward—a straight run through an exterior wall—you can buy materials (ductwork, wall cap, fasteners, sealant) for $50 to $150 and do the work yourself. This saves labor but requires cutting through framing and exterior walls accurately, which is not trivial if you've never done it.

Materials and supplies you'll need to budget for

Beyond labor, the installer will need ductwork, a wall or roof cap, fasteners, sealant, and possibly dampers or elbows. Rigid ductwork (aluminum or galvanized steel) costs $1 to $3 per linear foot; flexible ductwork costs $0.50 to $1.50 per foot but is less efficient and more prone to kinking. A wall cap runs $20 to $60; a roof cap with flashing runs $40 to $100. Dampers (which prevent backflow) cost $15 to $40.

If the installer has to patch drywall, paint, or caulk after running ductwork, those materials and labor are sometimes included in the quote and sometimes billed separately. Ask upfront whether finishing work is included or will cost extra.

Some installers include materials in their quoted price; others quote labor only and add materials on top. Always clarify what's included before work begins.

When to replace existing ductwork

If you're replacing an old range hood with a new one, the existing ductwork may be reusable if it's in good condition and the new hood's duct diameter matches the old one. Most range hoods use 6-inch or 8-inch diameter ducts. If the old ductwork is damaged, kinked, or the wrong size, replacement adds $200 to $600 to the job.

Ductwork that vents into the attic instead of outside (a common mistake in older homes) should be rerouted to an exterior wall or roof. This is a more expensive job—often $600 to $1,200—because it requires running new ductwork the full distance to the outside. However, it's worth doing because attic venting allows moisture to accumulate and can damage insulation and framing.

Getting an accurate quote for your home

The only way to know what installation will cost in your home is to have a local HVAC contractor or appliance installer visit and assess the job. When you call for a quote, describe your kitchen layout, where the range hood will be located, and where you want it to vent (exterior wall, roof, or soffit). If you already own the hood, have the model number and duct diameter ready.

Most contractors offer free in-home estimates. Get quotes from at least two installers so you can compare pricing and approach. Some may suggest routing options you hadn't considered, which could save money or improve performance.

If you're buying a new range hood, ask the retailer whether installation is included or available at a discount. Some appliance stores offer $100 to $200 off installation if you buy the hood from them, which can offset part of the labor cost.

Frequently Asked Questions

Can I vent a range hood into the attic instead of outside?

No. Venting into the attic traps moisture, which damages insulation, framing, and can cause mold. Range hoods must vent to the outside through an exterior wall, roof, or soffit. If your current hood vents into the attic, rerouting it to an exterior wall is a worthwhile upgrade, though it costs more upfront.

How much does it cost to add a range hood to a kitchen that doesn't have one?

If there's no existing ductwork, you're paying for the full installation: ductwork materials, wall or roof cap, labor, and any wall or ceiling patching. Expect $500 to $1,500 depending on routing. If you choose a recirculating hood instead, the cost drops to $200 to $400 because no ductwork is needed.

Do I need a damper in my range hood vent?

A damper prevents outside air and pests from entering your kitchen through the duct when the hood is off. Most building codes require one, and they cost $15 to $40. Some range hoods have a built-in damper; others need one installed in the ductwork. Ask your installer whether one is included.

What's the difference between rigid and flexible ductwork, and does it affect cost?

Rigid ductwork is more efficient and lasts longer but costs slightly more and requires more precise routing. Flexible ductwork is cheaper and easier to install around obstacles but loses efficiency over long runs and can kink. Most installers use rigid ductwork for the main run and flexible for short connections. The cost difference is usually $50 to $150 total.

Can I install a range hood vent myself to save money?

If the ductwork is straightforward—a straight run through an exterior wall—you can do it yourself and save $200 to $400 in labor. You'll need to cut through framing and siding accurately, which requires a drill, hole saw, and some carpentry skill. Complex runs through walls or attics are harder and risk improper sealing, which reduces performance and can cause moisture problems. Most people hire a professional for anything beyond a straightforward wall vent.
