A complete range hood installation quote gives each part of the job its own line and its own price: the hood, the labor to hang it, the duct run and exterior cap, electrical, makeup air if the hood is large enough to need it, the permit, and the patching afterward. If your bid has fewer lines than that, each missing item is either not part of the job or is folded into a bigger number. Find out which before you sign.

This matters because the spread in range hood installs is wide. Angi's cost guide, updated September 21, 2026, put the 2026 national average at $1,750, with typical jobs running $650 to $2,500. Most of that gap comes from two lines: where the air goes and where the power comes from.

Seven lines, in the order the work happens

1. The hood. The quote should name the model and say who is buying it. HomeGuide puts the unit alone at $100 to $600, and Angi puts it at $100 to $1,500 depending on finish. If the installer supplies the hood, ask for the unit price as its own figure. Angi notes that pros can sometimes buy below retail. We found no reliable figure for how much installers typically mark up a hood. If a general contractor is managing the job, Homewyse puts GC overhead at 13 to 22% on top. Check that the listed CFM is an HVI-Certified rating. The Home Ventilating Institute warns that "inflated performance ratings are common" on uncertified hoods.

2. Labor. HomeGuide puts standard replacement labor at $100 to $250 and island hood labor at $200 to $500. Angi quotes $50 to $100 an hour for 1 to 4 hours. Hoods wider than 30 inches need two installers, so expect a higher line there.

3. Duct run and exterior cap. This line should state the diameter, the material and the route. HomeGuide prices ductwork at $40 to $65 per linear foot. Venting through an exterior wall runs $200 to $650. A roof vent runs $400 to $900 on a one-story home and $1,000 to $2,000 on a two-story home. Code calls for smooth-walled metal duct, so flexible or plastic duct on a standard hood is a red flag. Size matters as well. CopperSmith puts 6-inch duct at roughly 400 to 500 CFM and 8-inch at 500 to 1,000 CFM. A bigger blower cannot make up for a duct that is too small.

4. Makeup air. Under the International Residential Code, a hood exhausting more than 400 CFM needs a makeup air system that brings in roughly the same amount of outside air. The exception is a home where every fuel-fired appliance is direct-vent or mechanically exhausted (GreenBuildingAdvisor). HVACDatabase prices makeup air systems at $1,000 to $3,000. According to Hauslane, New York City requires makeup air at any CFM.

5. Electrical. Connecting to an existing outlet can cost nothing. HomeGuide prices a new outlet at $150 to $350 and a new circuit at $250 to $900, with electrician labor at $50 to $130 an hour.

6. Permit. HomeGuide puts mechanical permits at $100 to $230, and some cities add a fire-safety inspection fee. Permits are usually needed when the job cuts a new exterior wall or roof opening or adds a new circuit. A straight replacement rarely needs one.

7. Patching and haul-away. Arspura puts drywall patching and paint at $100 to $300. HomeGuide puts removal of the old hood at $25 to $50.

Three bids you are likely to be holding

A like-for-like swap. Same size hood, existing duct, existing outlet. HomeGuide puts the total at $300 to $850. The bid should carry only the unit, labor and removal. If it also lists a duct line or a permit, ask what is changing.

A new wall-vented hood where there was none. This job includes a new outlet and new ductwork, and HomeGuide puts it at $650 to $2,100. Every one of the seven lines should appear except makeup air, provided the hood stays at or under 400 CFM.

A 36-inch gas range. FindsBeacon sizes a range of roughly 60,000 BTU at a 600 CFM minimum. That puts the hood over the 400 CFM line, so the bid should either include makeup air or explain in writing why your home is exempt. It should also call for 8-inch duct, not 6-inch. In New York, San Francisco and Boston, Arspura puts installation costs 15 to 25% above other areas.

Connecting power is not the same as adding a circuit

Most bids blur this line. A flat "electrical" charge with no scope is the most common padding on a range hood quote, because you cannot tell which of these two jobs you are paying for.

Connecting to existing power New outlet or circuit
What happens Hood plugs or wires into power already at the hood location Electrician runs new wiring from the panel or a nearby circuit
Fair range $0 (HVACDatabase) $150 to $350 outlet; $250 to $900 circuit (HomeGuide)
Permit Rarely Usually

A recirculating hood is also not a substitute for ducting. HVI states plainly that non-ducted hoods "provide no actual ventilation."

Before you sign

  • Ask who supplies the hood and what the unit costs on its own

    Compare it with the retail price of the same model.

  • Ask for the duct diameter, material, length and number of elbows

    Each 90-degree elbow adds about 15 feet of equivalent resistance, according to FindsBeacon.

  • Ask whether the hood is over 400 CFM and, if so, where makeup air is on the bid

    If the bid leaves it out, ask the installer to confirm in writing that your appliances make you exempt.

  • Replace a flat electrical line with a scope

    It should say existing connection, new outlet or new circuit.

  • Confirm who pulls the permit and that its fee is listed

    Contractors typically handle the application and the inspection.

  • Get the whole estimate in writing, including patching and cleanup

    HomeGuide advises confirming that all labor, parts and cleanup fees are listed before you authorize work.

Check the total against your region

Our pillar guide, [Range Hood Installation Cost by Type and Region](/range-hood-installation-cost-by-type-and-region/), breaks installed costs out by hood type so you can see where your bid lands.

The most reliable way to spot a padded line is to put two or three itemized bids side by side for the same hood.
