An outdoor barbecue exhaust fan, also called a range hood or a vent hood, generally costs between $1,000 and $4,000, as of February 2015, with the average price around $2,500. Prices vary depending on size, features, condition, discounts and brand.
Available sizes for outdoor barbecue range hoods usually range from 30-inches to 60-inches wide. Usual in-between sizes are 36, 42, 48 and 54 inches. Smaller or larger sizes may be available from some sources. The correct size to purchase can be determined from the size of the cooking area needing coverage.
Outdoor barbecue range hoods are built to withstand extensive smoke and grease-based fumes as well as inclement outdoor weather.
