exhaust fan installation cost
1 Many kitchen exhaust fans are part of a range hood, which can cost $30-$4,500, depending on size, type and cfm; installation adds another $250-$1,500, depending on whether the project is simply connecting and hanging the range hood, or if new metal ductwork must be installed to exhaust the air outdoors. It can cost $150-$600 or more for a powerful but quiet fan with most or all of the options -- decorative light fixture, heater, nightlight, timer, humidity sensor (turning the fan on whenever needed) and Energy Star rating.
