Product review (1 stars): Don't trust Broan!
We bought a Broan hood for our new (very expensive) kitchen re-build and it lasted for a little over 11 years. When the controller board failed, we were told "too bad" by Broan because it was past its 10-year warranty. They said the part was "no longer available" and if we wanted, they would sell us - get this - a replacement for full retail price (installation not included). They are not a company you want to do business with, unless you plan  on replacing their products every 10 years, which can be pretty pricey.
