Kitchen Ventilation Cost: Range Hood, Fan, and Installation Prices

Base Range Hood Prices by Type

The single largest factor in kitchen ventilation cost is the type of range hood you choose. Basic recirculating hoods that filter air and release it back into the kitchen typically start around $100 to $200. These are common in apartments or homes where ductwork cannot be easily added. At this price, you get a compact unit with a charcoal filter and a simple fan that moves 200 to 400 cubic feet per minute (CFM).

Ducted hoods, which vent air outside through a wall or roof, cost more because they require a metal duct and a more powerful blower. A basic ducted under-cabinet hood runs from $200 to $500. Mid-range models with stainless steel finishes, two or three fan speeds, and 400 to 600 CFM typically cost $400 to $800. High-end ducted hoods from brands like Zephyr, Broan, or Futuro with higher CFM ratings, noise insulation, and designer looks can cost $1,000 to $2,500 or more.

Island and wall-mounted chimney hoods are the most expensive style. A simple island hood starts around $300, but most functional models with adequate airflow for a standard kitchen cost $500 to $1,200. Premium island hoods with 600 to 900 CFM, glass canopies, or smart controls can exceed $2,000. Remember that the hood price is only part of the total; the cost of ducting and installation can add 50% to 100% to the project, especially if you need to run new ductwork through cabinets or the ceiling.

Inline and Remote Fan Costs

Instead of a hood with a built-in blower, some kitchens use a remote or inline fan mounted in the attic, basement, or on an exterior wall. These systems separate the fan motor from the intake grille, which makes the kitchen quieter. The price of an inline fan ranges from $150 to $600 depending on the CFM rating. A 400 CFM fan suitable for a small kitchen costs about $200, while a 1200 CFM unit for a large range or a pro-style cooktop can cost $500 to $800.

Remote fans are often paired with a simple ducted hood that has no motor, which can lower the cost of the hood itself. For example, a basic stainless steel wall hood without a blower might cost $150 to $300, and you add a separate inline fan for $250. The total for the fan and hood is often comparable to buying a hood with a built-in blower of similar performance. However, the installation is more complex because an electrician and a ductwork installer need to work in the attic or crawlspace.

Consider the total CFM you need before choosing a fan. A general rule is 100 CFM per 10,000 BTU of gas burner output, or 100 CFM per linear foot of cooktop. If your kitchen needs more than 600 CFM, you may also need a make-up air system. These systems bring in outside air to replace the air being exhausted, and they add $500 to $1,500 to the total kitchen ventilation cost, including the fan and installation.

Installation Labor Costs

Labor is a major part of kitchen ventilation cost, often $200 to $600 for a straightforward replacement of an existing ducted hood. If you are installing a new hood where none existed, the price rises significantly because the installer must cut through drywall, run ductwork, and possibly add a new electrical circuit. A typical installation for a new ducted range hood, including running duct through a cabinet and out an exterior wall, costs $400 to $900 for labor alone.

Electricians charge $100 to $250 per hour, and most range hoods require a dedicated circuit. If you don't already have an outlet or a hardwired connection near the cooktop, you may pay an extra $200 to $500 for electrical work. For a ductless hood that simply needs a plug-in outlet, the installation is simpler and cheaper, often $150 to $300 for labor. However, you will need to replace charcoal filters every 3 to 6 months, which adds a recurring cost of $15 to $30 per filter.

If your new hood has a higher CFM rating than your current one, the ductwork may need to be upgraded. Larger ducts, usually 6-inch or 8-inch round metal, are required for high-CFM fans. Replacing undersized duct can add $200 to $500 to the project. Always get a written estimate that includes the hood, duct materials, electrical work, and labor, and ask if the installer will patch the drywall, because that is often an additional $100 to $200.

Ductwork and Make-Up Air Costs

Ductwork costs range from $5 to $15 per linear foot for rigid metal duct, plus $10 to $30 per fitting like elbows and transitions. A typical installation uses 10 to 20 feet of duct, so materials alone might be $100 to $300. Flexible duct is cheaper, but it is not recommended for kitchen exhaust because the ribbed interior traps grease and reduces airflow. Most building codes require smooth, rigid metal duct for kitchen ventilation, so budget for that.

Make-up air is a separate but related cost. When a powerful range hood exhausts air, it creates negative pressure in the house. If your kitchen is tight or you have gas appliances, you may need a make-up air damper or a powered fan to bring in outside air. A basic passive make-up air damper costs $100 to $200, but a powered unit with a fan and motorized damper can cost $500 to $1,500, including installation. This is not an optional add-on for many high-CFM systems; building codes in some areas require it for exhaust fans over 400 CFM.

Before you commit to a specific hood, measure the distance from the cooktop to the exterior wall or roof. The longer the duct run, the higher the static pressure and the larger the duct needs to be. A professional installer can calculate the required duct size and CFM for your kitchen layout. Cutting corners on duct size or using too many elbows will reduce the fan's performance and increase noise, so it is worth paying for a proper design.

Hidden Costs and Long-Term Savings

Beyond the hood and installation, budget for a few incidentals. A new hood may require a different size electrical box, a new switch, or a range hood cover kit if the old hood was a different width. These parts add $20 to $100. You might also need to replace the backsplash or tile if you are changing the hood location. If you are installing a hood in a kitchen that has never had one, you may need to cut through crown molding or soffits, which can add $100 to $300 in labor.

Operating costs are another consideration. A typical range hood fan uses 100 to 300 watts on high, and if you run it 30 minutes a day, the annual electricity cost is about $5 to $15. However, a properly vented hood removes heat and humidity in the summer, which can reduce your air conditioning load. In the winter, exhausting warm air increases heating costs, but the impact is usually small—on the order of $20 to $50 per year for a typical household. The larger long-term saving is avoiding grease buildup on cabinets and walls, which can extend the life of your kitchen finishes.

Finally, consider the cost of filters. Metal mesh filters can be washed in the dishwasher and last for years, but charcoal filters for ductless hoods need replacing every 3 to 6 months. At $15 to $30 per filter, that is $30 to $60 per year. Some high-end hoods use baffle filters, which are more expensive to replace, but they are more efficient at trapping grease. Factor these consumables into your annual kitchen ventilation cost so you are not surprised later.
