Range hood installation: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering range hood installation

You install range hoods, mounting the unit, running ducting to the outside, wiring the fan and light and sealing every penetration. Customers judge the install on how well the hood clears smoke and how quiet and dry the duct stays.

What customers ask

  • Can you vent the hood outside?
  • What size duct does my hood need?
  • How do you seal the roof or wall opening?
  • Will the fan wiring work with my existing outlet?
  • Why is my hood so loud?

How to win the job

  • On the first call, ask for the hood model, the range position, the cabinet height and a photo of the wall or roof where the duct exits.
  • Confirm the duct route, length and bends before you arrive, and bring the duct, damper, exterior cap and sealant the job needs.
  • Use rigid or approved metal duct, keep bends low, and size the duct to the hood's outlet as the install guide directs.
  • Mount the hood into framing or blocking, and check that it is level and does not shift.
  • Test the fan on every speed and the light before you leave, and check the airflow at the exterior cap.
  • In the quote, list the duct size and material, the penetration method and which licensed trade does any electrical circuit work.

What to put on your profile

  • Photos of finished installs with clean duct runs and sealed exterior caps
  • The range hood brands you install most, listed by name
  • Whether you handle roof and masonry penetrations, and which ones you refer out

Follow-up that helps the customer

  • Offer a check of the duct airflow and the filters after the first few months of use
  • Suggest cleaning the grease filter on the schedule the manual recommends
  • Remind the customer to clean the exterior cap so it does not clog with lint and grease

Licenses and permits

Range hood installs that add new wiring can need a licensed electrician, and roof or wall penetrations and ducting can fall under local building rules that require a permit. Check state and local rules with your licensing agency and building department before taking this work.

Questions

Do I need a permit to vent a range hood through the roof?

Roof and wall penetrations often fall under local building rules, and a permit may be required. Check with your local building department before you cut.
